Black Arrow Cyber Threat Briefing 01 April 2021: Boards Still Aren't Taking Cyber Security Seriously, That Means Everyone Is At Risk; Nearly 40% Of New Ransomware Families Use Both Data Encryption And Data Theft In Attacks; Ransomware - Why We Are Now Facing A Perfect Storm; Nearly A Fifth Of Ransomware Victims Who Pay Off Extortionists Fail To Get Their Data Back; Shadow IT Is Your Organisation's Next Remote-Working Nightmare
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
Boards Still Aren't Taking Cyber Security Seriously, That Means Everyone Is At Risk
Cyber security still is not taken as seriously as it should be by boardroom executives – and that's leaving organisations open to cyber attacks, data breaches and ransomware, the new boss of the National Cyber Security Centre (NCSC) has warned. In her first speech since taking the helm of the UK cyber security agency, CEO Lindy Cameron said cyber security should be viewed with the same importance to CEOs as finance, legal or any other vital day-to-day part of the enterprise.
Nearly 40% Of New Ransomware Families Use Both Data Encryption And Data Theft In Attacks
2020 saw an explosion of ransomware that also steals data, giving the attackers more leverage over their victims. If organisations first refuse to pay a ransom to decrypt their data, attackers threaten to leak the stolen information, increasing pressure on victims to pay. This evolution, referred to as Ransomware 2.0 in the report, was a significant development in 2020. Only one ransomware group was observed using this type of extortion in 2019. By the end of 2020, 15 different ransomware families had adopted this approach. Furthermore, nearly 40% of ransomware families discovered in 2020, as well as several older families, were known to also steal data from victims by the end of last year.

Ransomware: Why We Are Now Facing A Perfect Storm
Ransomware is becoming more successful than ever before because of a combination of factors that allow cyber criminals to easily gain access to corporate networks – and they are finding success because a significant number of organisations that fall victim to attacks are willing to pay the ransom. A report warns that the 'perfect storm' of conditions have come together and allowed ransomware attacks to run rampant against organisations around the world.
https://www.zdnet.com/article/ransomware-why-were-now-facing-a-perfect-storm/
Ransomware: Nearly A Fifth Of Victims Who Pay Off Extortionists Fail To Get Their Data Back
The poll found that close to half (46%) of UK ransomware victims paid the ransom to restore access to their data last year, yet an unfortunate 11% of victims who shelled out did not have their stolen data returned. Whether they paid or not, only 18% of 1,006 UK victims surveyed were able to restore all their encrypted or blocked files following an attack. Internationally the picture is still worse with more than half (56%) paying off extortionists and nearly one in five of whom (17%) failing to get their data back even after paying out.
Billions Of Records Have Been Hacked Already. Make Cyber Security A Priority Or Risk Disaster
More data records have been compromised in 2020 alone than in the past 15 years combined, in what is described as a mounting "data breach crisis" in the latest study from analysis. Over the past 12 months, 31 billion data records have been compromised. This is up 171% from the previous year and constitutes well over half of the 55 billion data records that have been compromised in total since 2005.
Ransomware Gang Urges Victims’ Customers To Demand A Ransom Payment
A ransomware operation known as 'Clop' is applying maximum pressure on victims by emailing their customers and asking them to demand a ransom payment to protect their privacy. A common tactic used by ransomware operations is to steal unencrypted data before encrypting a victim's network. This data is then used in a double-extortion tactic where they threaten to release the data if a ransom is not paid.
Employee Lockdown Stress May Spark Cyber Security Risk
Stressed-out employees in a remote-working world could be a major contributor to poor cybersecurity postures for companies, according to a survey. Among other findings, the survey found that younger employees as well as people caring for children or other family members reported more stress in their lives, as well riskier IT behaviours when compared to other demographics. For instance, 67 percent of employees under 30 said they use shadow IT (unsanctioned apps, services, and equipment) to help them to perform certain tasks more easily, compared to 27 percent of older workers.
https://threatpost.com/employee-lockdown-stress-cybersecurity-risk/165050/
Shadow IT Is Your Organisation's Next Remote-Working Nightmare
Shadow IT refers to the use of devices, systems and software outside of those permitted by an organisational IT department. According to new research by software company Forcepoint, more than a third (37%) of UK employees are now relying on shadow IT at home, increasing companies' exposure to cyber security risks.
The use of personal devices appears to be one of the biggest culprits: 48% of respondents admitted to using their own devices to access work documents and corporate networks while working from home. Meanwhile, 34% of employees reported using private email or file-sharing cloud services for work purposes – again against the advice of employers.

Black Arrow Cyber Threat Briefing 29 January 2021
Black Arrow Cyber Threat Briefing 29 January 2021: Phishing Attacks Show High-Ranking Execs ‘Most Valuable Asset’ and ‘Greatest Vulnerability’; Paying Ransomware Funding Organised Crime; Police take down botnet that hacked millions of computers; After SolarWinds Hack, Who Knows What Cyber Dangers We Face; Russian businesses warned of retaliatory cyber attacks; iOS vulns actively exploited; Top Cyber Attacks of 2020
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
Phishing Attacks Show High-Ranking Execs May Be ‘Most Valuable Asset,’ and ‘Greatest Vulnerability’
Cyber criminals have been using a phishing kit featuring fake Office 365 password alerts as a lure to target the credentials of chief executives, business owners and other high-level corporate leaders. The scheme highlights the role and responsibility upper management plays in ensuring the security of their own company’s assets.
Insurers 'Funding Organised Crime' by Paying Ransomware Claims
Insurers are inadvertently funding organised crime by paying out claims from companies who have paid ransoms to regain access to data and systems after a hacking attack, Britain’s former top cybersecurity official has warned.
Emotet: Police raids take down botnet that hacked 'millions of computers worldwide'
Emotet, one of the world's most dangerous cyber crime services, has been taken down following one of the largest ever internationally-coordinated actions against cyber criminals. Although it began as banking malware designed to steal financial credentials, Emotet had become an infrastructure tool leased out to cyber criminals to break into victim computer networks and install additional malicious software.
After the SolarWinds Hack, We Have No Idea What Cyber Dangers We Face
Months before insurgents breached the Capitol and rampaged through the halls of Congress, a stealthier invader was muscling its way into the computers of government officials, stealing documents, monitoring e-mails, and setting traps for future incursions. Last March, a hacking team, believed to be affiliated with Russian intelligence, planted malware in a routine software upgrade from a Texas-based I.T. company called SolarWinds, which provides network-management systems to more than three hundred thousand clients.
FSB warns Russian businesses of cyber attacks as retaliation for SolarWinds hack
Russian authorities are alerting Russian organizations of potential cyberattacks launched by the United States in response to SolarWinds attack. The Russian intelligence agency FSB has issued a security alert this week warning Russian organizations of potential cyberattacks launched by the United States in response to the SolarWinds supply chain attack.
Update your iPhone — Apple just disclosed hackers may have 'actively exploited' a vulnerability in its iOS
On Tuesday released a new iOS software update that includes fixes for three security weaknesses in the former version. Its support website that it is aware of the three security bugs and that they "may have been actively exploited. “Also, it does not disclose details regarding security issues "until an investigation has occurred."
Top Cyber Attacks of 2020
"Zoombomb" became the new photobomb—hackers would gain access to a private meeting or online class hosted on Zoom and shout profanities and racial slurs or flash pornographic images. Nation-state hacker groups mounted attacks against organisations involved in the coronavirus pandemic response, including the World Health Organization and Centres for Disease Control and Prevention, some in an attempt to politicize the pandemic.

Black Arrow Cyber Threat Briefing 15 January 2021
Black Arrow Cyber Threat Briefing 15 January 2021: Two Thirds of Employees Don’t Consider Security Whilst Working from Home; Ransomware Gangs Targeting Top Execs; Microsoft emits 83 security fixes – and miscreants are already exploiting vulnerabilities in Windows Defender; Android malware gives hackers full control of your smartphone; Massive fraud campaign sees millions vanish from online bank accounts
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
Two-Thirds of Employees Don’t Consider Security Whilst Home Working
More than two-thirds (68%) of UK workers do not consider the cyber security impact of working from home, according to a new study. The survey of 2043 employees in the UK demonstrated a lack of awareness about how to stay secure whilst working remotely, which is putting businesses at risk of attacks. The shift to home working as a result of COVID-19 means that staff in many organizations are operating across insecure devices and networks, providing opportunities for cyber-criminals.
https://www.infosecurity-magazine.com/news/two-thirds-employees-security-home/
Ransomware Gangs Scavenge for Sensitive Data by Targeting Top Executives
In their attempt to extort as much money as quickly as possible out of companies, ransomware gangs know some effective techniques to get the full attention of a firm’s management team. And one of them is to specifically target the sensitive information stored on the computers used by a company’s top executives, in the hope of finding valuable data that can best pressure bosses into approving the payment of a sizeable ransom.
Microsoft emits 83 security fixes – and miscreants are already exploiting one of the vulnerabilities in Windows Defender
83 vulnerabilities in its software, which does not include the 13 flaws fixed in its Edge browser last week. That's up from 58 repairs made in December, 2020, a relatively light month by recent standards. Affected applications include: Microsoft Windows, Microsoft Edge (EdgeHTML-based), Microsoft Office and Microsoft Office Services and Web Apps, Microsoft Windows Codecs Library, Visual Studio, SQL Server, Microsoft Malware Protection Engine, .NET Core, .NET Repository, ASP .NET, and Azure.
https://www.theregister.com/2021/01/12/patch_tuesday_fixes/
This Android malware claims to give hackers full control of your smartphone
The 'Rogue' remote administration tool (RAT) infects victims with a keylogger, allowing attackers to easily monitor the use of websites and apps in order to steal usernames and passwords, as well as financial data. The low cost of the malware reflects the increasing sophistication of the criminal ecosystem that is making it possible for wannabe crooks with limited technical skills to acquire the tools to stage attacks.
Massive fraud campaign sees millions vanish from online bank accounts
Researchers have uncovered an extensive fraud campaign that saw millions of dollars drained from victims’ online bank accounts. The operation was discovered by experts at IBM Trusteer, the IT giant’s security division, who described the attack as unprecedented in scale. To gain access to online banking accounts, the fraudsters are said to have utilized a piece of software known as a mobile emulator, which creates a virtual clone of a smartphone.
SolarWinds Hack Followed Years of Warnings of Weak Cyber Security
Congress and federal agencies have been slow or unwilling to address warnings about cyber security, shelving recommendations that are considered high priority while investing in programs that have fallen short. The massive cyber-attack by suspected Russian hackers, disclosed in December, came after years of warnings from a watchdog group and cyber security experts. For instance, the Cyberspace Solarium Commission, which was created by Congress to come up with strategies to thwart sizable cyber-attacks, presented a set of recommendations to Congress in March that included additional safeguards to ensure more trusted supply chains.

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.

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.

Enter WAPDropper – An Android Malware Subscribing Victims to Premium Services by Telecom Companies
WAPDropper, a new malware which downloads and executes an additional payload. In the current campaign, it drops a WAP premium dialler which subscribes its victims to premium services without their knowledge or consent.
The malware, which belongs to a newly discovered family, consists of two different modules: the dropper module, which is responsible for downloading the 2nd stage malware, and a premium dialler module that subscribes the victims to premium services offered by legitimate sources – In this campaign, telecommunication providers in Thailand and Malaysia.
https://research.checkpoint.com/2020/enter-wapdropper-subscribe-users-to-premium-services-by-telecom-companies/
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
UK-based cyber-security vendor Sophos is currently notifying customers via email about a security breach the company suffered earlier this week.
Exposed information included details such as customer first and last names, email addresses, and phone numbers (if provided).
Privacy
Microsoft productivity score feature criticised as workplace surveillance
Microsoft has been criticised for enabling “workplace surveillance” after privacy campaigners warned that the company’s “productivity score” feature allows managers to use Microsoft 365 to track their employees’ activity at an individual level.
The tools, first released in 2019, are designed to “provide you visibility into how your organisation works”, according to a Microsoft blogpost, and aggregate information about everything from email use to network connectivity into a headline percentage for office productivity.

If you’re pressed for time watch the 60 second quick fire video summary of the top cyber and infosec stories from the last week:
Half of employees admit they are cutting corners when working from home
Half of employees are cutting corners with regards to cyber security while working from home – and could be putting their organisation at risk of cyber attacks or data breaches as a result.
The coronavirus pandemic has forced both employers and employees to quickly adjust to remote working – and, often without the watchful eyes of IT and information security teams, workers are taking more risks online and with data than they would at the office.
Analysis by researchers reveals that 52% of employees believe they can get away with riskier behaviour when working from home, such as sharing confidential files via email instead of more trusted mechanisms.
Some of the top reasons employees aren't completely following the same safe data practices as usual include working from their own device, rather than a company issued one, as well as feeling as if they can take additional risks because they're not being watched by IT and security.
In some cases, employees aren't purposefully ignoring security practices, but distractions while working from home are having an impact on how people operate.
Meanwhile, some employees say they're being forced to cut security corners because they're under pressure to get work done quickly.
Half of those surveyed said they've had to find workarounds for security policies in order to efficiently do the work they're required to do – suggesting that in some cases, security policies are too much of a barrier for employees working from home to adapt to.

C-Level Executives the Weakest Link in Organisations’ Mobile Security
C-suite executives are the people most susceptible to mobile-based cyber-attacks in businesses, according to a new study. The report found that while these executives are highly targeted by cyber-criminals in attacks on organisations, they are also more likely than anyone else to have a relaxed attitude to mobile security.
In the analysis, research from 300 enterprise IT decision makers across Benelux, France, Germany, the UK and the US was combined with findings from 50 C-level executives from the UK and the US. It revealed that many C-level executives find mobile security protocols frustrating, with 68% feeling IT security compromises their personal privacy, 62% stating it limits the usability of their device and 58% finding it too complex to understand.
As a result of these issues, 76% of C-suite executives had asked to bypass one or more of their organisation’s security protocols last year. This included requests to: gain network access to an unsupported device (47%), bypass multi-factor authentication (45%) and obtain access to business data on an unsupported app (37%).
These findings are concerning because all of these C-suite exemptions drastically increase the risk of a data breach. Accessing business data on a personal device or app takes data outside of the protected environment, leaving critical business information exposed for malicious users to take advantage of. Meanwhile, multi-factor identification – designed to protect businesses from the leading cause of data breaches, stolen credentials – is being side-stepped by C-suite execs.
To exacerbate this issue, IT decision makers included in the study overwhelmingly stated that C-suite is the group most likely to both be targeted by (78%), and fall victim to (71%), phishing attacks.
These findings highlight a point of tension between business leaders and IT departments. IT views the C-suite as the weak link when it comes to cyber security, while execs often see themselves as above security protocols.

Majority of companies suffered a cloud data breach in the past 18 months
Nearly 80% of companies have experienced at least one cloud data breach in the past 18 months, and 43% reported 10 or more breaches, a new survey reveals.
According to the 300 CISOs that participated in the survey, security misconfiguration (67%), lack of adequate visibility into access settings and activities (64%) and identity and access management (IAM) permission errors (61%) were their top concerns associated with cloud production environments.
Meanwhile, 80% reported they are unable to identify excessive access to sensitive data in IaaS/PaaS environments. Only hacking ranked higher than misconfiguration errors as a source of data breaches.
Even though most of the companies surveyed are already using IAM, data loss prevention, data classification and privileged account management products, more than half claimed these were not adequate for protecting cloud environments.

NSA and NCSC publicly warn of attacks by Kremlin hackers – so take this critical Exim flaw seriously
The NSA has raised the alarm over what it says is Russia's active exploitation of a remote-code execution flaw in Exim for which a patch exists.
The American surveillance agency said last week that the Kremlin's military intelligence hackers are actively targeting some systems vulnerable to CVE-2019-10149, a security hole in the widely used Exim mail transfer agent (MTA) that was fixed last June.
Because Exim is widely used on millions of Linux and Unix servers for mail, bugs in the MTA are by nature public-facing and pose an attractive target for hackers of all nations.

Malware-laced CVs steal banking credentials from users' PCs
If you work for a financial institution that happens to be hiring, be extra careful when downloading and opening CVs - many could be carrying a password-stealing banking malware.
This is according to a new report which identified the new malware distribution campaign in the wild.
According to the report, criminals are sending out emails with the subject lines “applying for a job” and “regarding job”, containing an Excel attachment with a malicious macro. Once the file is opened, the victim is prompted to “enable content”, which triggers the download of ZLoader malware.
ZLoader is capable of stealing credentials from the infected PC, as well as passwords and cookies stored in the target’s browser. With the stolen intel, the attacker could also use the victim’s device to make illicit financial transactions.

Hackers are targeting your smartphone as way into the company network, mobile phishing up a third in a few months
The number of phishing attacks targeting smartphones as the entry point for attempting to compromise enterprise networks has risen by more than a third over the course of just a few months.
Analysis by cyber security company Lookout found that there's been a 37% increase in mobile phishing attacks worldwide between the last three months of 2019 and the first few months of 2020 alone.
Phishing emails have long been a problem for desktop and laptop users, but the increased use of mobile devices – especially as more people are working remotely – has created an additional attack vector for cyber criminals who are targeting both Android and IOS phones.
Attacks targeting desktop email applications can leave tell-tale signs that something might not be quite right, such as being able to preview links and attachments, or see email addresses and URLs that might look suspicious.
However, this is harder to spot on mobile email, social media and messaging applications because the way they're designed for smaller screens.

Tens of thousands of malicious Android apps flooding user devices
Tens of thousands of dangerous Android apps are putting mobile users at heightened risk of fraud and cyber attack, a report has claimed.
A mobile security firm identified over 29,000 malicious Android apps in active use during Q1 2020, double the number logged in the same quarter last year (just over 14,500).
The investigation also showed that almost all (90%) of the ten most malicious apps were - or are still - present on the official Google Play Store. This suggests that hackers consistently found ways to dance their way through Google’s vetting system.
In line with this trend, this time period also saw a 55% rise in fraudulent transactions on Android platforms, as well as a spike in the number of malware-infected devices.

George Floyd: Anonymous hackers re-emerge amid US unrest
As the United States deals with widespread civil unrest across dozens of cities, "hacktivist" group Anonymous has returned from the shadows.
The hacker collective was once a regular fixture in the news, targeting those it accused of injustice with cyber-attacks.
After years of relative quiet, it appears to have re-emerged in the wake of violent protests in Minneapolis over the death of George Floyd, promising to expose the "many crimes" of the city's police to the world.
However, it's not easy to pin down what, if anything, is genuinely the mysterious group's work.
The "hacktivist" collective has no face, and no leadership. Its tagline is simply "we are legion", referring to its allegedly large numbers of individuals.
Without any central command structure, anyone can claim to be a part of the group.
This also means that members can have wildly different priorities, and there is no single agenda.
But generally, they are activists, taking aim at those they accuse of misusing power. They do so in very public ways, such as hijacking websites or forcing them offline.
Their symbol is a Guy Fawkes mask, made famous by Alan Moore's graphic novel V for Vendetta, in which an anarchist revolutionary dons the mask to topple a corrupt fascist government.

EasyJet Cyber Attack Likely the Work of Chinese Hackers
The recent high-profile cyber attack that struck British budget airline easyJet may have been carried out by Chinese hackers, new research and multiple sources have suggested.
The cyber attack, which saw the email addresses and travel details of millions of passengers being robbed—as well as the credit card details of some 2,000—was reportedly conducted by the very same group of Chinese hackers responsible for other attacks on a number of airlines in recent months.
