Welcome to this week’s Black Arrow Cyber Threat Briefing – a weekly digest, collated and curated by our cyber experts to provide senior and middle management with an easy to digest round up of the most notable threats, vulnerabilities, and cyber related news from the last week.
Top Cyber Stories of the Last Week
Ransomware Preparedness Is Low Despite Executives’ Concerns
86.7% of C-suite and other executives say they expect the number of cyber attacks targeting their organisations to increase over the next 12 months, according to a recent poll conducted by researchers. While 64.8% of polled executives say that ransomware is a cyber threat posing major concern to their organisations over the next 12 months, only 33.3% say that their organisations have simulated ransomware attacks to prepare for such an incident. https://www.helpnetsecurity.com/2021/09/15/ransomware-preparedness/
MSPs That Cannot Modernize Will Find Themselves And Their Clients Falling Behind
Researchers sought feedback from IT professionals to explore the performance of modern (and not-so-modern) managed service providers (MSPs). The survey found that even satisfactory MSPs are falling short in certain key areas: cloud strategy, security, and IT spending. https://www.helpnetsecurity.com/2021/09/16/msps-falling-behind/
Two-Thirds Of Cloud Attacks Could Be Stopped By Checking Configurations, Research Finds
On Wednesday, researchers published its latest Cloud Security Threat Landscape report, spanning Q2 2020 through Q2 2021. According to the research, two out of three breached cloud environments observed by the tech giant "would likely have been prevented by more robust hardening of systems, such as properly implementing security policies and patching systems." https://www.zdnet.com/article/two-thirds-of-cloud-attacks-could-be-stopped-by-checking-configurations-research-finds/
Open Source Software Cyber Attacks Increasing By 650%, Popular Projects More Vulnerable
Researchers released a report that revealed continued strong growth in open source supply and demand dynamics. Further, with regard to open source security risks, the report reveals a 650% year over year increase in supply chain attacks aimed at upstream public repositories, and a fascinating dichotomy pertaining to the level of known vulnerabilities present in popular and non-popular project versions. https://www.helpnetsecurity.com/2021/09/17/open-source-cyberattacks/
Third-Party Cloud Providers: Expanding The Attack Surface
In the era of digital transformation, which is essentially an organisation’s way of stating they are increasing their reliance on cloud-based services—enterprises’, digital landscapes are more interconnected than ever before. This means that the company you buy a technology function from may have downstream third-party providers that enable plumbing, infrastructure and development technology that drive their business. With modern computing environments moving further away from the enterprise, the safety assumption paradigm is shifting. This has impacted the threat landscape because as organisations increase migration to the cloud (a third party), they must now consider that these newly onboarded third parties may have serious security issues that could present adversaries with opportunities to infiltrate your network. https://www.helpnetsecurity.com/2021/09/13/third-party-cloud-providers/
Ransomware Encrypts South Africa's Entire Dept Of Justice Network
The justice ministry of the South African government is working on restoring its operations after a recent ransomware attack encrypted all its systems, making all electronic services unavailable both internally and to the public. As a consequence of the attack, the Department of Justice and Constitutional Development said that child maintenance payments are now on hold until systems are back online. https://www.bleepingcomputer.com/news/security/ransomware-encrypts-south-africas-entire-dept-of-justice-network/
2021’s Most Dangerous Software Weaknesses
Researchers recently updated a list of the top 25 most dangerous software bugs, and it’s little surprise that a number of them have been on that list for years. The Common Weakness Enumeration (CWE) list represents vulnerabilities that have been widely known for years, yet are still being coded into software and being bypassed by testing. Both developers and testers presumably know better by now, but keep making the same mistakes in building applications. https://threatpost.com/2021-angerous-software-weaknesses/169458/
46% Of All On-Prem Databases Are Vulnerable To Attack, Breaches Expected To Grow
A five-year longitudinal study comprising nearly 27,000 scanned databases discovered that the average database contains 26 existing vulnerabilities. 56% of the Common Vulnerabilities and Exposures (CVEs) found were ranked as ‘High’ or ‘Critical’ severity, aligned with guidelines from the National Institute of Standards and Technology (NIST). This indicates that many organisations are not prioritizing the security of their data and neglecting routine patching exercises. Based on Imperva scans, some CVEs have gone unaddressed for three or more years. https://www.helpnetsecurity.com/2021/09/15/on-prem-databases-vulnerable/
Most Fortune 500 Companies’ External IT Infrastructure Considered At Risk
Nearly three quarters of Fortune 500 companies’ IT infrastructure exists outside their organisation, a quarter of which was found to have a known vulnerability that threat actors could infiltrate to access sensitive employee or customer data, as research reveal. https://www.helpnetsecurity.com/2021/09/15/external-it-infrastructure-risk/
Thousands Of Internet-Connected Databases Contain High Or Critical Vulnerabilities
After spending five years poring over port scan results, researchers reckon there's about 12,000 vulnerability-containing databases accessible through the internet. The study also found that of the 46 per cent of 27,000 databases scanned, just over half that number contained "high" or "critical" vulns as defined by their CVE score. https://www.theregister.com/2021/09/14/imperva_12k_database_vuln_report/
Only 30% Of Enterprises Use Cloud Services With End to End Encryption For External File Sharing
A recent study of enterprise IT security decision makers conducted by researchers shows that majority of enterprises use additional encryption methods to boost the security of cloud collaboration and file transfer, however, tools with built-in end-to-end encryption are still less frequent despite the growing popularity of this privacy and security enhancing technology. https://www.helpnetsecurity.com/2021/09/13/external-file-sharing/

Black Arrow Cyber Threat Briefing 14 May 2021: Two Thirds Of CISOs Expect Damaging Cyber Attack In Next 12 Months; Ransomware - Don't Pay, It Just Shows Cyber Criminals That Attacks Work; Most Significant Cyber Attacks 2006-2020; The Shape Of Fraud And Cyber Crime, 10 Things We Learned From 2020; US Pipeline Ransomware Serves As Warning To Persistent Corporate Inertia Over Security; Ransomware Attackers Now Using Triple Extortion Tactics; AXA Pledges To Stop Reimbursing French Ransomware Victims; Cyber Experts Warn Over Online Wine Scams
Welcome to this week’s Black Arrow Cyber Threat Briefing – a weekly digest, collated and curated by our cyber experts to provide senior and middle management with an easy to digest round up of the most notable threats, vulnerabilities, and cyber related news from the last week.
Top Cyber Stories of the Last Week
Two Thirds Of CISOs Across World Expect Damaging Cyber Attack In Next 12 Months
More than 1,000 CISOs around the world have expressed concerns about the security ramifications of the massive shift to remote work since the beginning of the pandemic. One hundred CISOs from the US, Canada, the UK, France, Germany, Italy, Spain, Sweden, the Netherlands, UAE, Saudi Arabia, Australia, Japan, and Singapore were interviewed for the report, with many highlighting significant problems in the current cyber security landscape.
Ransomware: Don't Pay Up, It Just Shows Cyber Criminals That Attacks Work, Warns Home Secretary
For victims of ransomware attacks, paying the ransom does not guarantee that their network will be restored – and handing money to criminals only encourages them to try their luck infecting more companies with the file-encrypting malware. The impact of ransomware attacks continues to rise as cyber criminals encrypt networks, while also blackmailing victims with the prospect of stolen data being published, to generate as much money as possible from extortion.
The Most Significant Cyber Attacks From 2006-2020, By Country
Committing a cyber crime can have serious consequences. In the US, a cyber criminal can receive up to 20 years in prison for hacking into a government institution if it compromises national security. Yet, despite the consequences, cyber criminals continue to wreak havoc across the globe. But some countries seem to be targeted more than others. Using data from SpecOps Software, this graphic looks at the countries that have experienced the most significant cyber attacks over the last two decades.
https://www.visualcapitalist.com/cyber-attacks-worldwide-2006-2020/
The Shape Of Fraud And Cyber Crime: 10 Things We Learned From 2020
While it remains true that the older you are, the greater the financial loss, why would fraudsters target the young, who are arguably less well off? The answer lies in volume. Criminals have been offsetting higher monetary gain for higher attack rates, capitalising on the fact that the young are perhaps both more liberal with personal information (and privacy in general) and, at the same time, heavy digital users (social media, surveys, games, and so on). In fact, it is scary to see how much value the humble email address can have for criminals. We often forget that once obtained, it can be used further down the line to commit more fraud.
Is Third-Party Software Leaving You Vulnerable To Cyber Attacks?
When companies buy digital products, they expect them to be secure. In most cases, they do not test for vulnerabilities down the digital supply chain — and do not even have adequate processes or tools to do so. Hackers have taken note, and incidents of supply chain cyber attacks, which exploit weaknesses within the digital supply chain to break into organisations’ internal networks, are on the rise. As a result, there have been many headline incidents that not only bring shame to the companies involved, but rachet up the visibility of these threats to top executives who want to know their offerings are secure.
https://hbr.org/2021/05/is-third-party-software-leaving-you-vulnerable-to-cyberattacks
US Pipeline Ransomware Attack Serves As Fair Warning To Persistent Corporate Inertia Over Security
Organisations that continue to disregard the need to ensure they have adopted basic cyber security hygiene practices should be taken to task. This will be critical, especially as cyber criminals turn their attention to sectors where cyber threats can result in real-world risks, as demonstrated in the US Colonial Pipeline attack. In many of my conversations with cyber security experts, there is a shared sense of frustration that businesses still are failing to get some of the most basic things right. Default passwords are left unchanged, frontline staff and employees are still falling for common scams and phishing attacks, and major businesses think nothing of using technology that are decades old.
Ransomware Attackers Are Now Using Triple Extortion Tactics
The number of organisations affected by ransomware so far this year has more than doubled, compared with the same period in 2020, according to the report. Since April, Check Point researchers have observed an average of 1,000 organisations impacted by ransomware every week. For all of 2020, ransomware cost businesses worldwide around $20 billion, more than 75% higher than the amount in 2019. The healthcare sector has been seeing the highest volume of ransomware with around 109 attacks per organization each week. Amid news of a ransomware attack against gas pipeline company Colonial Pipeline, the utilities sector has experienced 59 attacks per organization per week. Organisations in the insurance and legal sector have been affected by 34 such attacks each week.
https://www.techrepublic.com/article/ransomware-attackers-are-now-using-triple-extortion-tactics/
AXA Pledges To Stop Reimbursing Ransom Payments For French Ransomware Victims
Insurance company AXA has revealed that, at the request of French government officials, it will end cyber insurance policies in France that pay ransomware victims back for ransoms paid out to cyber criminals. While unconfirmed, the Associated Press reported that the move was an industry first. AXA is one of the five biggest insurers in Europe and made the decision as ransomware attacks become a daily occurrence for organisations across the world.
The Dystopic Future Of Cyber Security And The Importance Of Empowering CISOs
Over a decade ago, in 2007, the first iPhone was released and with it emerged an ecosystem of apps that continues to expand to this day. This was a watershed moment, not solely for the technology industry, but civilization. It was a catalyst for what was to come. Suddenly, every consumer could access the internet at a touch of a button, and the accumulation of their data by private companies began en masse. It was at this point that data was established as an increasingly valuable commodity, and in turn, became a heightened exploitation risk. It also instigated a wave of innovation that has yet to break and is only growing rapidly in pace. In this state, technology providers, users, and manufacturers get excited about new functionalities, new features, new developments, while little thought is given to the negative consequences that could arise as a result. Indeed, fear has no place in the state of innovation as it is this primal thinking that inhibits creativity.

Cyber Security Experts Warn Over Online Wine Scams
Online wine scams became a bigger threat as cyber criminals sought to take advantage of more people and businesses organising virtual drinks and ordering bottles on the internet in the wake of Covid-19 restrictions, suggests the report. So-called ‘phishing emails’ were a particular concern, according to findings published in April by US-based group Recorded Future in partnership with Area 1 Security. From January 2020 onwards, the authors found a significant rise in legitimate wine-themed web domain registrations using terms like Merlot, Pinot, Chardonnay or Vino.

Black Arrow Cyber Threat Briefing 26 March 2021
Black Arrow Cyber Threat Briefing 26 March 2021: Cyber Warfare Will Grind Britain’s Economy To A Halt; $2 Billion Lost To BEC Scams In 2020; Ransomware Gangs Targets Firms With Cyber Insurance; Three Billion Phishing Emails Are Sent Every Day; $50 Million Ransomware For Computer Maker Acer; Office 365 Phishing Attack Targets Financial Execs; MS Exchange Hacking, Thousands Of Email Servers Still Compromised; Average Ransom Payment Surged 171% in 2020; Phishers’ Perfect Targets: Employees Getting Back To The Office; Nasty Malware Stealing Amazon, Facebook And Google Passwords
Welcome to this week’s Black Arrow Cyber Threat Briefing – a weekly digest, collated and curated by our cyber experts to provide senior and middle management with an easy to digest round up of the most notable threats, vulnerabilities, and cyber related news from the last week.
Top Cyber Stories of the Last Week
Cyber Warfare Will Grind Britain’s Economy To A Halt
The UK Integrated Security, Defence, Development and Foreign Policy Review was published this week, reflecting on current concerns and previously announced initiatives. The policy made it clear that emerging networks and technologies, such as electric vehicle charging points, provide an opportunity for adversaries to unbalance, paralyse or even defeat us, and a large scale attack on the UK could grind Britain’s economy to a halt.
https://www.telegraph.co.uk/technology/2021/03/22/cyber-warfare-will-grind-britains-economy-halt/
Almost $2 Billion Lost To BEC Scams In 2020
Losses emanating from Business Email Compromise (BEC) and Email Account Compromise (EAC) scams surpassed US$1.86 billion last year, which is more than the combined losses stemming from the next six costliest types of cyber crime. 19,000 reports of BEC/EAC scams last year, a decrease compared to the almost 24,000 incidents reported in 2019. The associated losses, however, increased by over US$90 million and accounted for 45 percent of the total losses (US$4.2 billion).
https://www.welivesecurity.com/2021/03/23/almost-2billion-lost-bec-scams-2020/
Ransomware Gang Says It Targets Firms Who Have Cyber Insurance
What I found particularly fascinating was a claim made by “Unknown” that the REvil gang specifically targets firms who have taken out insurance against ransomware attacks – presumably in the understandable belief that those corporate victims are more likely to pay up.
https://grahamcluley.com/ransomware-gang-says-it-targets-firms-with-cyber-insurance/
Three Billion Phishing Emails Are Sent Every Day
Cyber criminals are sending over three billion emails a day as part of phishing attacks designed to look like they come from trusted senders. By spoofing the sender identity used in the 'from' field in messages, cyber criminals attempt to lure potential victims into opening emails from names they trust. This could be the name of a trusted brand like a retailer or delivery company, or even, in more sophisticated attacks, the name of their CEO or a colleague.
Ransomware Gang Demands $50 Million From Computer Maker Acer
Acer has suffered a ransomware attack over the past weekend at the hands of the REvil ransomware gang, which is now demanding a whopping $50 million ransom payment to decrypt the company’s computers and not leak its data on the dark web. The attack has not disrupted production systems but only hit the company’s back-office network. The security breach was not deemed disruptive enough to prevent or delay the computer maker from announcing its Q4 2020 financial results on Wednesday.
https://therecord.media/ransomware-gang-demands-50-million-from-computer-maker-acer/
Office 365 Phishing Attack Targets Financial Execs
A new phishing scam is on the rise, targeting executives in the insurance and financial services industries to harvest their Microsoft 365 credentials and launch business email compromise (BEC) attacks. These new, sophisticated attacks are aimed at C-suite executives, their assistants, and financial departments, and can work around email security and Office 365 defences.
https://threatpost.com/office-365-phishing-attack-financial-execs/164925/
Microsoft Exchange Hacking: Thousands Of Email Servers Still Compromised – Ransomware Operators Still Piling In On Already Hacked Servers
Thousands of Microsoft Exchange servers are still compromised by hackers even after applying fixes. Owners of email servers that were compromised before Microsoft Corp. issued a patch nearly three weeks ago must take additional measures to remove the hackers from their networks. Microsoft has previously warned that patching will not evict a hacker who has already compromised a server.
Average Ransom Payment Surged 171% in 2020
The average ransomware payment soared by 171% year-on-year in 2020 as cyber crime gangs queued up to exploit the pandemic. The security vendor’s Unit 42 division compiled its Ransomware Threat Report 2021 from analysis of over 19,000 network sessions, 252 ransomware leak sites and 337 victim organizations.
https://www.infosecurity-magazine.com/news/average-ransom-payment-surged-171/
Phishers’ Perfect Targets: Employees Getting Back To The Office
Phishers have been exploiting people’s fear and curiosity regarding breakthroughs and general news related to the COVID-19 pandemic from the very start and will continue to do it for as long it affects out private and working lives. Cyber criminals continually exploit public interest in COVID-19 relief, vaccines, and variant news, spoofing the Centers for Disease Control (CDC), U.S. Internal Revenue Service (IRS), U.S. Department of Health and Human Services (HHS), World Health Organization (WHO), and other agencies and businesses.
https://www.helpnetsecurity.com/2021/03/22/phishers-employees/
Nasty Malware Stealing Amazon, Facebook And Google Passwords
A new piece of malware called CopperStealer is lurking in “cracked” software downloads available on pirated-content sites, and the malware can compromise your login info for Amazon, Apple, Facebook and Google, among other services. Notably, CopperStealer runs on the same basic principles as SilentFade, a pernicious piece of malware that ravaged Facebook accounts back in 2019.

Top Cyber Stories of the Last Week
Tens Of Thousands Of Microsoft Exchange Customers Are Under Assault From Hackers, Experts Warning Of Unprecedented Damage, Exploits Being Targeted By "At Least 10 Hacker Groups"
Four exploits in Microsoft Exchange Server hit the news last week, when we heard that a Chinese hacking group had targeted the email servers of some 30,000 U.S. government and commercial organisations. The exploits had been patched by Microsoft, but the hacking group known as “Hafnium” had doubled-up on efforts targeting unpatched servers. Security researchers found that at least 10 APT groups are taking advantage of the exploits in an attempt to compromise servers around the world. Winniti Group, Calypso, Tick, and more are among the groups identified.
https://www.techspot.com/news/88913-microsoft-exchange-server-exploits-targeted-least-10-hacker.html
Over $4.2 Billion Officially Lost To Cyber Crime In 2020
Cyber crime affecting victims in the U.S., noting a record number of complaints and financial losses in 2020 compared to the previous year. The Internet Crime Complaint Center (IC3) received last year 791,790 complaints - up by 69% from 2019 - of suspected internet crime causing more than $4 billion in losses. While most complaints were for phishing, non-payment/non-delivery scams, and extortion, about half of the losses are accounted by business email compromise (BEC), romance and confidence scams, and investment fraud.
Cyber Attacks Multiply On Wealthy Investors
An email nearly cost a wealthy British art collector £6m, after hackers monitored email correspondence between the client and an art dealer the client had been negotiating with for a year, with hackers impersonating the genuine art dealer, learning to impersonate the tone and language used — even gleaning private family news and the names of partners and children.
Just when the collector and the art dealer finally reached a conclusion on price, the client received an email to say something along the lines of, I hope the children are recovering from their colds — we have just amended our bank details for security and here they are. As it matched the tone of previous emails the art-loving client didn't think anything was amiss.
Fortunately, his family office phoned the real dealer to check the transaction before approving a transfer and the scam was discovered in time, but many people are not so lucky.

Cyber Strength Now Key To National Security, Says UK
In what has been billed as the largest security and foreign policy strategy revamp since the Cold War, the UK government has outlined new defence priorities – with at their heart, the imperative to boost the use of new technologies to safeguard the country. Prime minister Boris Johnson unveiled the integrated review this week, which has been in the making for over a year and will be used as a guide for spending decisions in the future. Focusing on foreign policy, defense and security, the review sets goals for the UK to 2025; and underpinning many of the targets is the objective of modernizing the country's armed forces.
https://www.zdnet.com/article/cyber-strength-now-key-to-national-security-says-uk/
Largest Ransomware Demand Now Stands At $30 Million As Crooks Get Bolder
Ransomware shows no sign of slowing down as the average ransom paid to cyber criminals by organisations that fall victim to these attacks has nearly tripled over the past year. Cyber security researchers analysed ransomware attacks targeting organisations across North America and Europe and found that the average ransom paid in exchange for a decryption key to unlock encrypted networks rose from $115,123 in 2019 to $312,493 in 2020.
Mimecast: SolarWinds Attackers Stole Source Code
Hackers who compromised Mimecast networks as part of the SolarWinds espionage campaign have swiped some of the security firm’s source code repositories, according to an update by the company. The email security firm initially reported that a certificate compromise in January was part of the sprawling SolarWinds supply-chain attack that also hit Microsoft, FireEye and several U.S. government agencies.
https://threatpost.com/mimecast-solarwinds-attackers-stole-source-code/164847/
71 Percent Of Office 365 Users Suffer Malicious Account Takeovers
88 percent of companies have accelerated their cloud and digital transformation projects due to COVID-19. But it also finds that 71 percent of Microsoft Office 365 deployments have suffered an account takeover of a legitimate user's account, not just once, but on average seven times in the last year.

More Than 16 Million Covid-Themed Cyber Attacks Launched In 2020
COVID-19 dominated everyone's lives throughout 2020 but a new report from a cyber security company found that the pandemic was also the main theme of nearly 16.5 million threats and attacks launched against its customers. Researchers wrote that they dealt with 16,393,564 threats that had a COVID-19-related tint to them, with 88% of the threats coming in spam emails and another 11% coming in the form of URLs. Malware accounted for 0.2%, or nearly 33,000, of the threats
“Expert” Hackers Used 11 0-Days To Infect Windows, iOS, And Android Users
Using novel exploitation and obfuscation techniques, a mastery of a wide range of vulnerability types, and a complex delivery infrastructure, the group exploited four zero-days in February 2020. The hackers’ ability to chain together multiple exploits that compromised fully patched Windows and Android devices led members of Google’s Project Zero and Threat Analysis Group to call the group “highly sophisticated.”
Cyber Attacks: Is The ‘Big One’ Coming Soon?
2020 was the year that the COVID-19 crisis also brought a cyber pandemic. Late last year, the security industry’s top experts from global cyber security company leadership predicted even worse cyber security outcomes for 2021 compared to what we saw in 2020. In December, we learned about how SolarWinds’ Orion vulnerability was compromised, causing one of the worst data breaches in history that is still evolving for about 18,000 organisations.

Welcome to this week’s Black Arrow Cyber Threat Briefing – a weekly digest, collated and curated by our cyber experts to provide senior and middle management with an easy to digest round up of the most notable threats, vulnerabilities, and cyber related news from the last week.
Top Cyber Stories of the Last Week
New Strain Of Ransomware Implements Self-Spreading Capabilities
French experts spotted a new Ryuk ransomware variant that implements self-spreading capabilities to infect other devices on victims’ local networks.
This new version has a new attribute that allows it to self replicate over the local network allowing the malware to propagate itself – machine to machine – within the Windows domain. Once launched, it will spread itself to every Windows machine it can reach.
https://securityaffairs.co/wordpress/115064/reports/ryuk-ransomware-self-spreading-capabilities.html
One In Four People Use Work Passwords For Consumer Websites
The report found that one in four consumers admit to using their work email or passwords to log in to consumer websites and applications such as food delivery apps, online shopping sites and even dating apps. The report found that consumers are neglecting to implement fundamental security safeguards across smart IoT devices at home, which could have serious security ramifications on both the individual and the enterprise amid increased and ongoing remote work spurred by the COVID-19 pandemic.
https://www.helpnetsecurity.com/2021/02/26/use-work-passwords-for-consumer-websites/
Massive Rise In Threats Across Expanding Attack Surfaces
New malware samples nearly doubled: New ransomware samples increased 106% year-over-year. Trojans increased 128%, with threat actors using trojans to exploit lower-severity vulnerabilities. Sophisticated, multi-staged attacks and malware-as-a-service have become the norm. Vulnerabilities hit a new high: 18,341 new vulnerabilities in 2020 have been reported. To stay ahead of attacks, security and risk leaders need sophisticated insights into which vulnerabilities are high-risk and remediation options for all assets, including non-patching options.
https://www.helpnetsecurity.com/2021/02/26/expanding-attack-surfaces/
Half of Organisations Concerned Remote Working Puts Them at Greater Risk of Cyber Attacks
Half of organizations are concerned that the shift to remote work is putting them a greater risk of Cyber Attacks, according to a new study with IDG. A survey of UK CIOs, CTOs and IT decision makers revealed that insecure practices are regularly taking place among remote workers, providing more opportunities for Cyber Criminals to strike.

A Booming Trade In Bugs Is Undermining Cyber Security
If you discover that a favourite vending-machine dispenses free chocolate when its buttons are pressed just so, what should you do? The virtuous option is to tell the manufacturer, so it can fix it. The temptation is to gorge.
Is Your Browser Extension A Botnet Backdoor?
A company that rents out access to more than 10 million Web browsers so that clients can hide their true Internet addresses has built its network by paying browser extension makers to quietly include its code in their creations. This story examines the lopsided economics of extension development, and why installing an extension can be such a risky proposition.
https://krebsonsecurity.com/2021/03/is-your-browser-extension-a-botnet-backdoor/
Cyber Attack Shuts Down Online Learning At 15 UK Schools
A threat actor was able to access the trust's central network infrastructure and while an investigation took place, all existing phone, email, and website communication had to be pulled. Students are still learning remotely in England. Schools are set to reopen on March 8, but in the meantime, only a small subset of children are attending school physically, such as the children of key workers.

First Fully Weaponized Spectre Exploit Discovered Online
A fully weaponized exploit for the Spectre CPU vulnerability was uploaded on the malware-scanning website VirusTotal last month, marking the first time a working exploit capable of doing actual damage has entered the public domain. The exploit was discovered and targets Spectre, a major vulnerability that was disclosed in January 2018. According to its website, the Spectre bug is a hardware design flaw in the architectures of Intel, AMD, and ARM processors that allows code running inside bad apps to break the isolation between different applications at the CPU level and then steal sensitive data from other apps running on the same system.

Solarwinds Security Fiasco May Have Started With Simple Password Blunders
We still do not know just how bad the SolarWinds security breach is. We do know over a hundred US government agencies and companies were cracked. "The largest and most sophisticated attack the world has ever seen," with more than a thousand hackers behind it. It may have all started when an intern first set an important password to "'solarwinds123." Then, adding insult to injury, the intern shared the password on GitHub.

Black Arrow Cyber Threat Briefing 27 November 2020
Black Arrow Cyber Threat Briefing 27 November 2020: Hundreds of C-level executives’ credentials available for $100 to $1500; Bluetooth Attack Can Steal a Tesla Model X in Minutes; Three members of TMT cybercrime group arrested in Nigeria; Cyber criminals make £2.5m raid on law firms in lockdown; Hackers post athletes’ naked photos online
Welcome to this week’s Black Arrow Cyber Threat Briefing – a weekly digest, collated and curated by our cyber experts to provide senior and middle management with an easy to digest round up of the most notable threats, vulnerabilities and cyber related news from the last week.
Top Cyber Headlines of the Week
Hundreds of C-level executives’ credentials available for $100 to $1500 per account
A credible threat actor is offering access to the email accounts of hundreds of C-level executives for $100 to $1500 per account.
The availability of access to the email accounts of C-level executives could allow threat actors to carry out multiple malicious activities, from cyber espionage to BEC scams.
The threat actor is selling login credentials for Office 365 and Microsoft accounts and the price depends on the size of the C-level executives’ companies and the internal role of the executive.
The threat actor claims its database includes login credentials of high-level executives such as:
CEO, CTO, COO, CFO, CMO. President, Vice President, Executive Assistant, Finance Manager, Accountant, Director, Finance Director, Financial Controller and Accounts Payables
https://securityaffairs.co/wordpress/111588/cyber-crime/executives-credentials-dark-web.html
This Bluetooth Attack Can Steal a Tesla Model X in Minutes
Tesla has always prided itself on its so-called over-the-air updates, pushing out new code automatically to fix bugs and add features. But one security researcher has shown how vulnerabilities in the Tesla Model X's keyless entry system allow a different sort of update:
A hacker could rewrite the firmware of a key fob via Bluetooth connection, lift an unlock code from the fob, and use it to steal a Model X in just a matter of minutes.
https://www.wired.com/story/tesla-model-x-hack-bluetooth/
Three members of TMT cybercrime group arrested in Nigeria
Three Nigerians suspected of being part of a cybercrime group that has made tens of thousands of victims around the world have been arrested today in Lagos, Nigeria, Interpol reported.
In a report disclosing its involvement in the investigation, security firm Group-IB said the three suspects are members of a cybercrime group they have been tracking since 2019 and which they have been tracking under the codename of TMT.
Group-IB said the group primarily operated by sending out mass email spam campaigns containing files laced with malware.
https://www.zdnet.com/article/three-members-of-tmt-cybercrime-group-arrested-in-nigeria/
Cyber criminals make £2.5m raid on law firms in lockdown
The large number of lawyers working from home has become a magnet for cyber criminals, the Solicitors Regulation Authority has said, revealing a 300% increase in phishing scams in the first two months of lockdown alone.
In the first half of 2020, firms reported that nearly £2.5m held by them had been stolen by cybercriminals, more than three times the amount reported in the same period in 2019.
Law firm staff working remotely on less secure devices than the office network and those without dedicated office space finding it hard to keep information confidential. Those using video meetings also need to make sure that unauthorised parties cannot overhear or see a confidential meeting.
Hackers post athletes’ naked photos online
Four British athletes are among hundreds of female sports stars and celebrities whose intimate photographs and videos have been posted online in a targeted cyberattack.
The hack, which the athletes became aware of this week, has caused panic and one leading sports agency has advised its clients to take extra measures to protect their private data.
The athletes, who had photographs and videos stolen from their phones, were considering steps last night to have the material removed from the dark net.
https://www.thetimes.co.uk/article/hackers-post-athletes-naked-photos-online-86sq27hgl
Threats
Ransomware
Manchester United hackers 'demanding million-pound ransom'
Manchester United are still suffering the effects of a significant cyberattack that targeted the club earlier this week.
Following last weekend's 'sophisticated' attack, the club has revealed it is still suffering severe disruption to its internal systems, several of which had to be shut down following the incident.
Reports have also claimed that the hackers are demanding "millions of pounds" before they let the club regain full control.
https://www.techradar.com/sg/news/manchester-united-hackers-demanding-million-pound-ransom
Egregor Ransomware Attack Hijacks Printers to Spit Out Ransom Notes
The South American retail giant Cencosud was hit with ransomware last week? The retailer was infected by an Egregor ransomware attack which, in time honoured fashion, stole sensitive files that it found on the compromised network, and encrypted data on Cencosud’s drives to lock workers out of the company’s data.
A text file was left on infected Windows computers, telling the store that private data would be shared with the media if it was not prepared to begin negotiating with the hackers within three days.
That’s nothing unusual, but Egregor’s novel twist is that it can also tell businesses that their computer systems are well and truly breached by sending its ransom note to attached printers.
Sopra Steria: Adding up outages and ransomware clean-up, Ryuk attack will cost us up to €50m
Sopra Steria has said a previously announced Ryuk ransomware infection will not only cost it "between €40m and €50m" but will also deepen expected financial losses by several percentage points.
The admission comes weeks after the French-headquartered IT outsourcing firm's Active Directory infrastructure was compromised by malicious people who deployed the Ryuk ransomware, using what the company called "a previously unknown strain."
https://www.theregister.com/2020/11/25/sopra_steria_ransomware_damage_50m_euros/
Phishing
GoDaddy scam shows how voice phishing can be more deceptive than email schemes
Companies can protect employees from phishing schemes through a combination of training, secure email gateways and filtering technologies. But what protects workers from phone-based voice phishing (vishing) scams, like the kind that recently targeted GoDaddy and a group of cryptocurrency platforms that use the Internet domain registrar service?
Experts indicate that there are few easy answers, but organizations intent on putting a stop to such activity may have to push for more secure forms of verification, escalation procedures for sensitive requests, and better security awareness of account support staffers and other lower-level employees.
Google Services Weaponized to Bypass Security in Phishing, BEC Campaigns
A spike in recent phishing and business email compromise (BEC) attacks can be traced back to criminals learning how to exploit Google Services, according to research from Armorblox.
Social distancing has driven entire businesses into the arms of the Google ecosystem looking for a reliable, simple way to digitize the traditional office. A report detailing how now-ubiquitous services like Google Forms, Google Docs and others are being used by malicious actors to give their spoofing attempts a false veneer of legitimacy, both to security filters and victims.
Malware
Malware creates scam online stores on top of hacked WordPress sites
A new cybercrime gang has been seen taking over vulnerable WordPress sites to install hidden e-commerce stores with the purpose of hijacking the original site's search engine ranking and reputation and promote online scams.
The attacks were discovered earlier this month targeting a WordPress honeypot which was set up and managed.
The attackers leveraged brute-force attacks to gain access to the site's admin account, after which they overwrote the WordPress site's main index file and appended malicious code.

LightBot: TrickBot’s new reconnaissance malware for high-value targets
The notorious TrickBot gang has released a new lightweight reconnaissance tool used to scope out an infected victim's network for high-value targets.
Over the past week, security researchers began to see a phishing campaign normally used to distribute TrickBot's BazarLoader malware switch to installing a new malicious PowerShell script.
IoT
The smart video doorbells letting hackers into your home
Smart doorbells with cameras let you see who’s at the door without getting up off the sofa, but in-depth security testing has found some are leaving your home wide open to uninvited guests.
With internet-connected smart tech on the rise, smart doorbells are a common sight on UK streets. Popular models, such as Ring and Nest doorbells, are expensive, but scores of similar looking devices have popped up on Amazon, eBay and Wish at a fraction of the price.
https://www.which.co.uk/news/2020/11/the-smart-video-doorbells-letting-hackers-into-your-home/
Password Attacks
Up to 350,000 Spotify accounts hacked in credential stuffing attacks
An unsecured internet-facing database containing over 380 million individual records, including login credentials that were leveraged for breaking into 300,000 to 350,000 Spotify accounts. The exposed records included a variety of sensitive information such as people’s usernames and passwords, email addresses, and countries of residence.
The treasure trove of data was stored on an unsecured Elasticsearch server that was uncovered. Both the origin and owners of the database remain unknown. However, the researchers were able to validate the veracity of the data as Spotify confirmed that the information had been used to defraud both the company and its users.
Passwords exposed for almost 50,000 vulnerable Fortinet VPNs
A hacker has now leaked the credentials for almost 50,000 vulnerable Fortinet VPNs.
Over the weekend a hacker had posted a list of one-line exploits to steal VPN credentials from these devices.
Present on the list of vulnerable targets are IPs belonging to high street banks, telecoms, and government organizations from around the world.
Vulnerabilities
UK urges orgs to patch critical MobileIron RCE bug
The UK National Cyber Security Centre (NCSC) issued an alert yesterday, prompting all organizations to patch the critical CVE-2020-15505 remote code execution (RCE) vulnerability in MobileIron mobile device management (MDM) systems.
An MDM is a software platform that allows administrators to remotely manage mobile devices in their organization, including the pushing out of apps, updates, and the ability to change settings. This management is all done from a central location, such as an admin console running on the organization's server, making it a prime target for attackers.
Critical Unpatched VMware Flaw Affects Multiple Corporates Products
VMware has released temporary workarounds to address a critical vulnerability in its products that could be exploited by an attacker to take control of an affected system.
"A malicious actor with network access to the administrative configurator on port 8443 and a valid password for the configurator admin account can execute commands with unrestricted privileges on the underlying operating system," the virtualization software and services firm noted in its advisory.
Tracked as CVE-2020-4006, the command injection vulnerability has a CVSS score of 9.1 out of 10 and impacts VMware Workspace One Access, Access Connector, Identity Manager, and Identity Manager Connector.

GitHub fixes 'high severity' security flaw spotted by Google
GitHub has finally fixed a high severity security flaw reported to it by Google Project Zero more than three months ago.
The bug affected GitHub's Actions feature – a developer workflow automation tool was "highly vulnerable to injection attacks".
GitHub's Actions support a feature called workflow commands as a communication channel between the Action runner and the executed action.
https://www.zdnet.com/article/github-fixes-high-severity-security-flaw-spotted-by-google/
Google Chrome users still vulnerable to multiple zero-day attacks
As business users and consumers have moved most of their workloads to the cloud, more and more of their work is being done in web browsers such as Google Chrome as opposed to in applications installed locally on their systems.
This means that the web browser is now an essential yet vulnerable entry point that if compromised, could give cybercriminals access to a user's entire digital life including their email, online banking, social networks and more. However, despite this risk, users are failing to update to the latest version of Google Chrome.
https://www.techradar.com/news/google-chrome-users-still-vulnerable-to-multiple-zero-day-attacks
Microsoft releases patching guidance for Kerberos security bug
Released details on how to fully mitigate a security feature bypass vulnerability in Kerberos KDC (Key Distribution Centre) patched during this month's Patch Tuesday.
The remotely exploitable security bug tracked as CVE-2020-17049 exists in the way KDC decides if service tickets can be used for delegation via Kerberos Constrained Delegation (KCD).
Kerberos is the default authentication protocol for domain connected devices running Windows 2000 or later. Kerberos KDC is a feature that manages service tickets used for encrypting messages between network servers and clients.
Data Breaches
Sophos notifies customers of data exposure after database misconfiguration

Coronavirus Scams: Prepare for Phishing Emails, Fake Alerts and Cyberthreats
As new global stories emerge by the hour on the coronavirus, bad actors are (again) trying to confuse online updates with phishing scams and destructive malware. Here’s why action is required now.
Wherever you turn for news coverage online, coronavirus alarm bells are ringing louder.
But users should not trust all of those bells, as fake news, phishing scams and even malicious malware is actively being distributed under the coronavirus umbrella.
Sadly, a perfect storm may be brewing. As government officials and health experts appeal louder for calm, the public is actually getting more worried and searching the Internet for answers.

Metamorfo Returns with Keylogger Trick to Target Financial Firms
The malware uses a tactic to force victims to retype passwords into their systems – which it tracks via a keylogger.
Researchers have discovered a recent spate of phishing emails spreading a new variant of Metamorfo, a financial malware known for targeting Brazilian companies. Now, however, it’s expanding its geographic range and adding a new technique.
Metamorfo was first discovered in April 2018, in various campaigns that share key commonalities (like the use of “spray and pray” spam tactics). These campaigns however have small, “morphing” differences — which is the meaning behind its name.
This newest variant, which targets payment-card data and credentials at financial institutions with Windows platforms, packs a new trick up its sleeve. Once executed, the malware kills the auto-suggest data entry fields in browsers, forcing victims to write out their passwords – which it then tracks via a keylogger.

What's in your network? Shadow IT and shadow IoT challenge technology sensibilities
A couple of years ago, a survey found most CIOs thought they had roughly 30 to 40 apps running within their enterprises, but researchers at Symantec estimated that the average enterprise actually had at least 1,516 applications -- a number that has doubled over a three-year period.
It's not that CIOs are naive. It's just that shadow IT is a difficult thing to measure, since employees pull down apps outside the official channels, and off budget sheets. To some degree, it's even purposely overlooked, condoned, or even encouraged, as employees need the right tools to do their jobs, and IT can't always be there.
Now, it appears CIOs are battling shadow IT on two fronts. There's the user-initiated apps and clouds, and there's something more insidious -- "shadow IoT."

Remote workers prime targets for cyber attacks
According to a study into the future of work, more than half of CIOs expect a rise in employees working remotely, while 97% say that soon their workforce will be widely dispersed across geographies and time zones. Businesses are being forced to adapt to the rising demand for a dynamic working environment, which can manifest as anything from workers bringing their own devices to work to employees using corporate machines at home as part of a flexible work schedule. However, this increases the security burden through the need for better identity management.

Critical Cisco vulnerabilities put millions of network devices at risk
Five different critical vulnerabilities, collectively known as CPDwn, have been discovered in Cisco’s Discovery Protocol, potentially putting tens of millions of enterprise network devices such as desk phones, cameras, and network switches, at risk.
Cisco Discovery Protocol (CDP) is a level 2 protocol that is used to discover information about Cisco equipment that are directly connected nearby.
According to researchers, this flaw could allow hackers to control the products deep within the network without any human intervention. This could be done remotely by just sending a malicious CDP packet to the target device.
This latest phishing scam is spreading fake invoices loaded with malware - campaigns are launched against financial institutions in the US and UK.
A notorious malware campaign is targeting banks and financial institutions in the US and the UK with cyberattacks that are not only destructive in their own right, but could also be used as the basis for future intrusions by other hackers.
Emotet started life as a banking trojan, but has also evolved into a botnet, with its criminal operators leasing out its capabilities to those who want to distribute their own malware to compromise machines.
Such is the power of Emotet that at one point last year it accounted for almost two-thirds of malicious payloads delivered in phishing attacks.
Emotet activity appeared to decline during December, but it sprung back to life in January – and it currently shows no signs of slowing down as researchers have detailed yet another campaign.

90% of UK Data Breaches Due to Human Error in 2019
Human error caused 90% of cyber data breaches in 2019, according to a CybSafe analysis of data from the UK Information Commissioner’s Office (ICO).
According to the cybersecurity awareness and data analysis firm, nine out of 10 of the 2376 cyber-breaches reported to the ICO last year were caused by mistakes made by end-users. This marked an increase from the previous two years, when respectively, 61% and 87% of cyber-breaches were ascribed to user error.
CybSafe cited phishing as the primary cause of breaches in 2019, accounting for 45% of all reports to the ICO. ‘Unauthorized access’ was the next most common cause of cyber-breaches in 2019, with reports relating to malware or ransomware, hardware/software misconfiguration and brute force password attacks also noted.

Police Warning: Cyber Criminals Are Using Cleaners to Hack Your Business
Criminal gangs are planting “sleepers” in cleaning companies so that they can physically access IT infrastructure, a senior police officer with responsibility for cyber crime has warned, urging businesses to bolster their physical security processes in the face of the growing threat.
Shelton Newsham, who manages the Yorkshire and Humber Regional Cyber Crime Team, told an audience at the SINET security event that he was seeing a “much larger increase in physical breaches” as cyber crime groups diversify how they attack and move laterally inside institutions.

The Mirai IoT botnet holds strong in 2020
The Mirai botnet has been a constant IoT security threat since it emerged in fall 2016. The subsequent release of its source code only extended Mirai's reach and is one of the many reasons it has been labelled the "king of IoT malware."
Mirai continues to be successful for a well-known reason: Its targets are IoT devices with hardcoded credentials found in a simple web search. Such devices listen for inbound telnet access on certain ports and have backdoors through which Mirai can enter. Once a device is subsumed in the botnet it immediately scans for other victims.

Governments Are Soft Targets for Cyber-criminals
New research has found that governments are more vulnerable to cyber-attacks than other organisations.
A report on the security of municipal governments and agencies identified three key factors that made governments particularly soft targets. Researchers found that governments had larger attack surfaces, lower usage rates of even the most basic email authentication schemes, and much higher rates of internal hosting than other organisations.
Government attack surfaces, consisting of open ports and applications, were found to be on average 33% larger than those risked by other organisations.

BYO Hardware Driver: New Ransomware Attacks Kernel Memory and brings its own vulnerability
A ransomware strain dubbed “RobbinHood” is using a vulnerability in a “legitimate” and signed hardware driver to delete security products from targeted computers before encrypting users files, according to security researchers.
The ransomware exploits a known vulnerability in the driver from Taiwan’s GIGABYTE to subvert a setting in kernel memory in Windows 10, 8 and 7, meaning it “brings its own vulnerability” and can attack otherwise patched systems.
