Top Cyber Stories of the Last Week

SMBs Increasingly Vulnerable To Ransomware, Despite The Perception They Are Too Small To Target

A new report this week warns that small and medium-sized businesses (SMBs) are at particular risk based on the attack trends seen during the first six months of the year. The report revealed that during the first half of 2021, 4 out of 5 organisations experienced a cyber security breach originating from a vulnerability in their third-party vendor ecosystem. That’s at a time when the average cost of a data breach rose to around $3.56 million, with the average ransomware payment jumping 33% to more than $100,000.

May 2021 Saw A 440% Increase In Phishing, The Single Largest Phishing Spike On Record

In May 2021, a report revealed a 440% increase in phishing, holding the record for the single largest phishing spike in a single month. It also showed that industries such as oil, gas and mining saw a 47% increase in the same six-month period, with manufacturing and wholesale traders seeing a 32% increase. The report extends its yearly threat intelligence report, with updated metrics between January 1 and June 30 2021. It also investigates the latest trends in malware, phishing and crypto exchanges.

Users Can Be Just As Dangerous As Hackers

Most organisations should be at least as worried about user management as they are about Bond villain-type hackers launching compromises from abroad. Most organisations have deployed single sign-on and modern identity-management solutions. These generally allow easy on-boarding, user management, and off-boarding. However, on mobile devices, these solutions have been less effective. Examples include mobile applications such as WhatsApp, Signal, Telegram, or even SMS-which are common in the workforce. All these tools allow for low-friction, agile communication in an increasingly mobile business environment. Today, many of these tools offer end-to-end encryption (e2ee), which is a boon when viewed through the lens of protecting against outside attackers. However, e2ee also resists internal governance and compliance programs.

With Crime-As-A-Service, Anyone Can Be An Attacker

Crime-as-a-Service (CaaS) is the practice of experienced cybercriminals selling access to the tools and knowledge needed to execute cyber crime – in particular, it’s often used to create phishing attacks. For hackers, phishing is one of the easiest ways to steal your organisation’s data. Traditionally, executing a successful phishing campaign required a seasoned cyber criminal with technical expertise and knowledge of social engineering. However, with the emergence of CaaS, just about anyone can become a master of phishing for a small fee.

The Rise Of Cloud Is Creating Security Blindspots

Businesses are growing increasingly reliant on cloud services, but with all the good, businesses must also face the bad, according to a new report which says that the rise of cloud means greater complexity and more security blind spots.

Increased expansion into the cloud has led to new risks. All of the respondents in the report had suffered at least one incident in their public cloud environment in the last year, with 30 percent saying they had no formal sign-off before pushing to production.

Connected Devices Increasingly At Risk As New Ransomware Attacks Are Reported Almost Daily

A report has been released on the state of connected devices. The 2021 study addresses pandemic-related cyber security challenges, including the growth of connected devices and related increase of security risks from these devices as threat actors took advantage of chaos to launch attacks. The study incorporates security risk and trend analysis of anonymized data for the past 12 months (June 2020 through June 2021) across the company’s 500+ deployments in healthcare, life sciences, retail, and manufacturing verticals. The number of agentless and un-agentable devices increased to 42% in this year’s report (compared to 32% of agentless or un-agentable devices in 2020).

The Value Of PII And How It Still Fuels Malign Activities In The Digital Ecosystem

The COVID-19 pandemic engendered new vulnerabilities in the digital ecosystem for threat actors to exploit, resulting in items like vaccines, fraudulent vaccine certificates, and other COVID-19 related items being sold in dark marketplaces and underground forums, an Intelligence report reveals. The research analysed the value of personally identifiable information (PII), drawing links between the breach economy, PII, and a range of emerging digital threats to executives and brands.

Ransomware Payments Explode Amid ‘Quadruple Extortion’

Two reports slap hard figures on what’s already crystal clear: Ransomware attacks have skyrocketed, and ransomware payments are the comet trails that have followed them skyward. The average ransomware payment spiked 82 percent year over year: It’s now over half a million dollars, according to the first-half 2021 update report. As far as the sheer multitude of attacks goes, researchers on Thursday reported that they’ve identified and analysed 121 ransomware incidents so far in 2021, a 64 percent increase in attacks, year-over-year.

Hackers Netting Average Of Nearly $10,000 For Stolen Network Access

A new report from a cyber security company has spotlighted the thriving market on the dark web for network access that nets cyber criminals thousands of dollars. Researchers have examined network access sales on underground Russian and English-language forums before compiling a study on why criminals sell their network access and how criminals transfer their network access to buyers. More than 37% of all victims in a sample of the data were based in North America while there was an average price of $9,640 and a median price of $3,000.

1M Stolen Credit Cards Hit Dark Web For Free

Threat actors have leaked 1 million stolen credit cards for free online as a way to promote a fairly new and increasingly popular cyber criminal site dedicated to…selling payment-card credentials. Researchers noticed the leak of the payment-card data during a “routine monitoring of cyber crime and Dark Web marketplaces,” researchers said in a post published over the weekend. The cards were published on an underground card-selling market, AllWorld.Cards, and stolen between 2018 and 2019, according to info posted on the forum.

Ransomware Group Demanding $50M In Accenture Security Breach

The hacker group behind a ransomware attack on global solution provider giant Accenture has made a ransom demand for $50 million, according to a cyber security firm that reports seeing the demand. The threat actor is demanding the $50 million in exchange for more than 6 TB of data, according to a tweet.

Black Arrow Cyber Threat Briefing 28 May 2021

Black Arrow Cyber Threat Briefing 28 May 2021: Cyber Insurance Firms Start Tapping Out As Ransomware Continues To Rise; Irish Health Service Faces Final Bill Of At Least €100M Following Cyber Attack; The 10 Most Dangerous Cyber Threat Actors; Dramatic Increase In Ransomware Attacks Is Causing Harm On A Significant Scale; Deepfakes Could Be The Next Big Security Threat To Businesses; Two-Thirds Of Organisations Say They'll Take Action To Boost Their Ransomware Defences

Top Cyber Stories of the Last Week

Cyber Insurance Firms Start Tapping Out As Ransomware Continues To Rise

In early May, global insurer AXA made a landmark policy decision: The company would stop reimbursing French companies for ransomware payments to cyber criminals. The decision, which reportedly came after French authorities questioned whether the practice had fuelled the current epidemic in ransomware attacks, may be just the beginning of a general retreat that will force companies to reconsider their attempts to outsource cyber-risk to insurance firms. Already, the massive damages from one damaging crypto worm, NotPetya, caused multiple lawsuits when insurers refused to pay out on cyber insurance claims.

Irish Health Service Faces Final Bill Of At Least €100M Following Cyber Attack

The cyber attack on IT systems in the health service will cost it at least €100 million, according to chief executive Paul Reid. This is at the lower end of estimates of the total cost, he indicated, and includes the cost of restoring the network, upgrading systems to Microsoft 365 and the disruption caused to patients. Appointments for about 7,000 patients a day are being cancelled, almost two weeks after a criminal gang hacked the HSE systems. Mr Reid said the HSE was keen to see an independent and objective assessment of the cyber attack.

Ransomware: Dramatic Increase In Attacks Is Causing Harm On A Significant Scale

A dramatic increase in the number of ransomware attacks and their severity is causing harm on a significant scale, the UK's National Crime Agency (NCA) has warned. The NCA's annual National Strategic Assessment (NSA) of Serious and Organised Crime details how the overall threat from cyber crime has increased during the past year, with more severe and high-profile attacks against victims. Ransomware attacks have grown in frequency and impact over the course of the last year, to such an extent that they rank alongside other major crimes "causing harm to our citizens and communities on a significant scale," warns the report.

Deepfakes Could Be The Next Big Security Threat To Businesses

An overwhelming majority of businesses say that manipulated online content and media such as deepfakes are a serious security risk to their organisation. Deepfakes have already been shown to pose a threat to people portrayed in the manipulated videos, and could have serious repercussions when the individual holds a position of importance, be it as a leader of a country, or a leader of an enterprise. Earlier in 2021, the FBI’s cyber division warned that deepfakes are a critical emerging threat that can be used in all manners of social engineering attacks including ones aimed at businesses.

Ransomware: Two-Thirds Of Organisations Say They'll Take Action To Boost Their Defences

The severe disruption caused by the Colonial Pipeline ransomware attack has alerted organisations to the need to bolster their defences against cyber attacks – and two-thirds are set to take actions required to prevent them becoming another ransomware victim following the incident. The ransomware attack against Colonial Pipeline – one of the largest pipeline operators in the United States, providing almost half of the East Coast's fuel – caused disruption to operations and led to gas shortages, demonstrating how cyber attacks can have physical consequences.

The 10 Most Dangerous Cyber Threat Actors

When hacking began many decades ago, it was mostly the work of enthusiasts fuelled by their passion for learning everything they could about computers and networks. Today, nation-state actors are developing increasingly sophisticated cyber espionage tools, while cyber criminals are cashing in millions of dollars targeting everything from Fortune 500 companies to hospitals. Cyber attacks have never been more complex, more profitable, and perhaps even more baffling. At times, drawing clear lines between different kinds of activities is a challenging task. Nation-states sometimes partner with each other for a common goal, and sometimes they even appear to be working in tandem with cyber criminal gangs.

Cyber Security Leaders Lacking Basic Cyber Hygiene

Constella Intelligence released the results of a survey that unlocks the behaviours and tendencies that characterize how vigilant organisations’ leaders are when it comes to reducing cyber vulnerability, allowing the industry to better understand how social media is leveraged as an attack vector and how leaders are responding to this challenge. The findings from the survey, which polled over 100 global cyber security leaders, senior-level to C-suite, across all major industries, including financial services, technology, healthcare, retail, and telecommunications, revealed that 57% have suffered an account takeover (ATO) attack in their personal lives—most frequently through email (52%), followed by LinkedIn (31%) and Facebook (26%).

Watch Out: Crypto Jacking Is On The Rise Again

During the last year, though, malicious crypto mining has seen a resurgence, with NTT’s 2021 Global Threat Intelligence Report, published this month, revealing that crypto miners have now overtaken spyware as the world’s most common malware. Crypto miners, says NTT, made up 41% of all detected malware in 2020, and were most widely found in Europe, the Middle East, Africa, and the Americas. The most common coinminer variant was XMRig, which infects a user’s computer to mine Monero, accounting for 82% of all mining activity. Others included Crypto miner and XMR-Stack.

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

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.

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.

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.
