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 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.

Black Arrow Cyber Threat Briefing 05 March 2021: New Strain Of Ransomware Implements Self-Spreading Capabilities; One In Four People Use Work Passwords For Consumer Websites; Massive Rise In Threats Across Expanding Attack Surfaces; Half of Orgs Concerned Remote Working Puts Them at Greater Risk of Cyber Attacks; Microsoft Patches Four Zero-Day Exchange Server Bugs; A Booming Trade In Bugs Is Undermining Cyber Security; Weaponized Spectre Exploit Discovered; Solarwinds Security Fiasco May Have Started With Simple Password Blunders
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.
https://www.infosecurity-magazine.com/news/half-orgs-remote-working-risk/
Microsoft Patches Four Zero-Day Exchange Server Bugs
Microsoft has been forced to release out-of-band patches to fix multiple zero-day vulnerabilities being exploited by Chinese state-backed threat actors. The unusual step was taken to protect customers running on-premises versions of Microsoft Exchange Server.
https://www.infosecurity-magazine.com/news/microsoft-patch-four-zeroday/
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.
https://www.zdnet.com/article/cyberattack-shuts-down-online-learning-at-15-uk-schools/
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.
https://therecord.media/first-fully-weaponized-spectre-exploit-discovered-online/
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 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.

Christmas malware spreading fast: Protect yourself now
Holiday party invitations may infect your PC
It's time for ugly Christmas sweaters — and for ugly Christmas-themed malicious spam emails.
A new malspam campaign dumps an email in your inbox marked "Christmas Party," "Christmas Party next week," "Party menu," "Holiday schedule" or something similar. But the attached Word document delivers a lump of coal: the notorious Emotet Trojan malware.
"HAPPY HOLIDAYS," begins the email, as spotted by researchers. "I have attached the menu for the Christmas Party next week. If you would like bring something, look at the list and let me know.
"Don't forget to get your donations in for the money tree," the email adds. "Also, wear your tackiest/ugliest Christmas sweater to the party." Sometimes it adds, "Details in the attachment."

Ransomware Gangs Now Outing Victim Businesses That Don’t Pay Up
As if the scourge of ransomware wasn’t bad enough already: Several prominent purveyors of ransomware have signaled they plan to start publishing data stolen from victims who refuse to pay up. To make matters worse, one ransomware gang has now created a public Web site identifying recent victim companies that have chosen to rebuild their operations instead of quietly acquiescing to their tormentors.
The cyber criminals behind the Maze Ransomware strain erected a Web site on the public Internet, and it currently lists the company names and corresponding Web sites for eight victims of their malware that have declined to pay a ransom demand.
“Represented here companies dont wish to cooperate with us, and trying to hide our successful attack on their resources,” the site explains in broken English. “Wait for their databases and private papers here. Follow the news!”
Researchers were able to verify that at least one of the companies listed on the site indeed recently suffered from a Maze ransomware infestation that has not yet been reported in the news media.
The information disclosed for each Maze victim includes the initial date of infection, several stolen Microsoft Office, text and PDF files, the total volume of files allegedly exfiltrated from victims (measured in Gigabytes), as well as the IP addresses and machine names of the servers infected by Maze.
As shocking as this new development may be to some, it’s not like the bad guys haven’t warned us this was coming.

Ransomware: The number of victims paying up is on the rise, and that's bad news
The number of organisations that are giving into the extortion demands of cyber criminals after falling victim to ransomware attacks has more than doubled this year.
A rise in the number of ransomware attacks in the past year has contributed to to the increased number of organisations opting to pay a ransom for the safe return of networks locked down by file-encrypting malware.
That's according to figures in the newly released 2019 CrowdStrike Global; Security Attitude Survey, which said the total number of organisations around the world that pay the ransom after falling victim to a supply-chain attack has more than doubled from 14% of victims to 39% of those affected.
In the UK specifically, the number of organisations that have experienced a ransomware attack and paid the demanded price for the decryption key stands at 28% – double the 14% figure of the previous year.

Microsoft Office apps hit with more cyber attacks than ever
New reports have claimed Microsoft Office was the most commonly exploited application worldwide as of the the third quarter of this year.
Researchers found that Microsoft Office solutions and applications were the target of exactly 72.85 percent of cyber exploits this year according to the firm's research.
However, cyber criminals also targeted web browsers with 13.47 percent of the total number of exploits, Android (9.09 percent), Java (2.36 percent), and Adobe Flash (1.57 percent).

Inconsistent password advice could increase risk of cyber attacks
New research suggests that ‘inconsistent and misleading’ password meters seen on various websites could increase the risk of cyber attacks.
The study, led by researchers at the University of Plymouth, investigated the effectiveness of 16 password meters that people are likely to use or encounter on a regular basis.
It tested 16 passwords against the various meters, with 10 of them being ranked among the world’s most commonly used passwords (including ‘password’ and ‘123456’).
Of the 10 explicitly weak passwords, only five of them were consistently scored as such by all the password meters, while ‘Password1!’ performed far better than it should do and was even rated strongly by three of the meters.
However, the team at Plymouth said one positive finding was that a browser-generated password was consistently rated strong, meaning users can seemingly trust these features to do a good job.

This ‘grab-bag’ hacking attack drops six different types of malware in one go
'Hornet's Nest' campaign delivers a variety of malware that could create a nightmare for organisations that fall victim to attacks, warn researchers.
A high-volume hacking campaign is targeting organisations around the world with attacks that deliver a 'grab-bag' of malware that includes information-stealing trojans, a remote backdoor, a cryptojacker and a cryptocurrency stealer.
Uncovered by researchers at Deep Instinct, the combination of the volume of attacks with the number of different malware families has led to the campaign being named 'Hornet's Nest'.
The attacks are suspected to be offered as part of a cybercrime-as-a-service operation with those behind the initial dropper, which researchers have dubbed Legion Loader, leasing out their services to other criminals.
Clues in the code point to the Legion Loader being written by a Russian-speaker – and researchers note that the malware is still being worked on and updated. Attacks using the loader appear to be focused on targets in the United States and Europe.

Tiny band of fraud police left to deal with third of all crime
Only one in 200 police officers is dedicated to investigating fraud despite it accounting for more than a third of all crimes, The Times revealed.
Most forces have less than half of 1 per cent of their officers allocated to fraud cases and some have none at all, according to figures disclosed under the Freedom of Information Act. In some areas the number of officers tackling fraud has fallen significantly.
Amid a surge in online and cold-calling scams, there were 3.8 million incidents of fraud last year, more than a third of all crimes in England and Wales. Victims are increasingly targeted online and can lose their life savings. However, as few as one in 50 fraud reports leads to a “judicial outcome” such as a suspect being charged.
Last night police bosses said the failure to investigate the cases was due to budget cuts and “poor government direction” and the situation had become a national emergency. Boris Johnson has pledged to “make the streets safer” by recruiting an extra 20,000 police officers but there are concerns that victims of fraud will continue to be failed.

IT worker with a grudge jailed for cyber attack that shut down network for 12 hours
A contractor with a grudge over the handling of an incident in Benidrom has been jailed for carrying out a revenge cyber attack. Scott Burns, 27, was unhappy with the way a disciplinary matter against him by Jet2 was dealt with so decided to cause harm. The attack led to the company’s computer network being shut down for 12 hours and it was only thanks to a fast-thinking colleague that a ‘complete disaster’ was avoided. Burns’s attack cost the company £165,000 in lost business, Leeds Crown Court was told. Jailing Burns for 10 months, Judge Andrew Stubbs QC heard how the motive was revenge because Burns was unhappy about how Jet2 dealt with a disciplinary matter against him relating to an incident at a ‘roadshow in Benidorm’ in 2017. No further details of the incident were outlined in court.

30 years of ransomware: How one bizarre attack laid the foundations for the malware taking over the world
In December 1989 the world was introduced to the first ever ransomware - and 30 years later ransomware attacks are now at crisis levels.
Ransomware has been one of the most prolific cyber threats facing the world throughout 2019, and it's unlikely to stop being a menace any time soon.
Organisations from businesses and schools to entire city administrations have fallen victim to network-encrypting malware attacks that are now demanding hundreds of thousands of dollars in bitcoin or other cryptocurrency for the safe return of the files.
While law enforcement recommends that victims don't give into the demands of cyber criminals and pay the ransom, many opt to pay hundreds of thousands of dollars because they view it as the quickest and easiest means of restoring their network. That means some of the criminal groups operating ransomware campaigns in 2019 are making millions of dollars.
But what is now one of the major cyber scourges in the world today started with much more humble origins in December 1989 with a campaign by one man that would ultimately influence some of the biggest cyber attacks in the world thirty years later.
The first instance of what we now know as ransomware was called the AIDS Trojan because of who it was targeting – delegates who'd attended the World Health Organization AIDS conference in Stockholm in 1989.
Attendees were sent floppy discs containing malicious code that installed itself onto MS-DOS systems and counted the number of the times the machine was booted. When the machine was booted for the 90th time, the trojan hid all the directories and encrypted the names of all the files on the drive, making it unusable.
Victims saw instead a note claiming to be from 'PC Cyborg Corporation' which said their software lease had expired and that they needed to send $189 by post to an address in Panama in order to regain access to their system.
It was a ransom demand for payment in order for the victim to regain access to their computer.
