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.
https://www.itproportal.com/news/the-rise-of-cloud-is-creating-security-blindspots/
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).
https://www.helpnetsecurity.com/2021/08/12/connected-devices-risks/
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.
https://www.helpnetsecurity.com/2021/08/10/pii-value-digital-ecosystem/
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.
https://www.zdnet.com/article/hackers-netting-average-of-nearly-10000-for-stolen-network-access/
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.
https://threatpost.com/1m-stolen-credit-cards-dark-web/168514/
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 21 May 2021: Ransomware Attacks Are Spiking. Is Your Company Prepared?; Ban Ransom Payments To Hackers, Urges Ex-GCHQ Boss; How Penetration Testing Can Promote A False Sense Of Security; Ransomware’s New Swindle - Triple Extortion; ‘It’s A Battle, It’s Warfare’ - Experts Seek To Defeat Ransomware Attackers; 5 Reasons Why Enterprises Need Cyber Security Awareness And Training; 10 Emerging Cyber Security Trends To Watch In 2021
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
5 Reasons Why Enterprises Need Cyber Security Awareness And Training
Research shows that most cyber attacks rely on exploiting the human factor with the help of creative and innovative phishing techniques and other attack vectors. Almost 90% of all data breaches are caused due to human error. Therefore, even if an organisation has a robust cyber security infrastructure in place, the absence of cyber security awareness among employees can leave a huge gap in its cyber security framework. This gap can be easily exploited by cyber criminals to launch various types of cyber attacks. Hence, cyber security awareness and training are very much needed for any enterprise to secure it against cyber attacks.
Ban Ransom Payments To Hackers, Urges Ex-GCHQ Boss
Britain’s former cyber security chief has called for a ban on ransomware payments after the Irish health service became the latest to be hit by a major attack from international criminals. Ciaran Martin, the founding chief executive of GCHQ’s National Cyber Security Centre (NCSC), said that making payments illegal would help to break the lucrative global hacking business model. Martin said that businesses were helping to fund the organised criminals who locked and stole their data. “At the moment you can pay to make it quietly go away. There’s no legal obligations involved,” he said. “There’s no obligation to report to anybody, there’s no traceability of payment of crypto currency. We have allowed this to spiral in an invisible way.”
Ransomware’s New Swindle: Triple Extortion
Ransomware attacks are exploding at a staggering rate, and so are the ransoms being demanded. Now experts are warning against a new threat — triple extortion — which means that attackers are expanding out to demand payments from customers, partners and other third parties related to the initial breach to grab even more cash for their crimes. Check Point’s latest ransomware report found that over the past year, ransomware payments have spiked by 171 percent, averaging about $310,000 — and that globally, the number of attacks has surged by 102 percent.
https://threatpost.com/ransomwares-swindle-triple-extortion/166149/
‘It’s A Battle, It’s Warfare’: Experts Seek To Defeat Ransomware Attackers
Cyber security experts like to joke that the hackers who have turned ransomware attacks into a multibillion-dollar industry are often more professional than even their biggest victims. Ransomware attacks — when cyber attackers lock up their target’s computer systems or data until a ransom is paid — returned to the spotlight this week after attacks hit one of the biggest petroleum pipelines in the US, Toshiba’s European business, and Ireland’s health service. While governments have pledged to tackle the problem, experts said the criminal gangs have become more enterprising and continue to have the upper hand. For businesses, they said, there is more pain to come. “This is probably the biggest conundrum in security because companies have to decide how far they participate in this cat-and-mouse game,” said Myrna Soto, former chief strategy and trust officer at Forcepoint and current board member of gas and electricity group Consumers Energy. “It’s a battle, it’s warfare, to be honest.”

Colonial Pipeline Boss Confirms $4.4M Ransom Payment
Its boss told the Wall Street Journal he authorised the payment on 7 May because of uncertainty over how long the shutdown would continue. "I know that's a highly controversial decision," Joseph Blount said in his first interview since the hack. The 5,500-mile (8,900-km) pipeline carries 2.5 million barrels a day. According to the firm, it carries 45% of the East Coast's supply of diesel, petrol and jet fuel. Chief executive Mr Blount told the newspaper that the firm decided to pay the ransom after discussions with experts who had previously dealt with DarkSide, the criminal organisation behind the attack.

10 Emerging Cyber Security Trends To Watch In 2021
A flurry of new threats, technologies and business models have emerged in the cyber security space as the world shifted to a remote work model in response to the COVID-19 pandemic. The lack of a network perimeter in this new world accelerated the adoption of SASE (secure access service edge), zero trust and XDR (extended detection and response) to ensure remote users and their data are protected. Adversaries have taken advantage of the complexity introduced by newly remote workforces to falsely impersonate legitimate users through credential theft and have upped the ante by targeting customers in the victim’s supply chain. The ability to monetize ransomware attacks by threatening to publicly leak victim data has made it more lucrative, while employers continue to fend off insiders with an agenda.

How Penetration Testing Can Promote A False Sense Of Security
Rob Gurzeev is concerned about blind spots—past and present. In his DarkReading article Defending the Castle: How World History Can Teach Cyber security a Lesson, Gurzeev mentioned, "Military battles bring direct lessons and, I find, often serve as a reminder that attack surface blind spots have been an Achilles' heel for defenders for a long time." "Cyber security attackers follow this same principle today," wrote Gurzeev. "Companies typically have a sizable number of IT assets within their external attack surface they neither monitor nor defend and probably do not know about in the first place."
https://www.techrepublic.com/article/how-penetration-testing-can-promote-a-false-sense-of-security/
Ransomware Attacks Are Only Getting Worse, Darkside Group "Quits," But That May Just Be A Strategy
Earlier this month, a hacker group named DarkSide launched a ransomware attack against the business network of the Colonial Pipeline, forcing the company to shut down the 5,500-mile main pipeline and leading to fuel shortages in 17 states and Washington DC last week. According to a Bloomberg report, Colonial paid 75 Bitcoin (around $5 million on the day of the transaction) in ransom to the Eastern European hackers, but officially the company has maintained a different narrative of not having any intention of paying the extortion fee in crypto currency, as the DarkSide group had demanded. However, the Georgia-based company is said to have made the payment within hours of the attack, possibly using a cyber insurance policy to cover it.

Learning From Cyber Attacks Could Be The Key To Stopping Them
Organisations should use major cyber incidents as a way to think through the core of their security strategies in order to prevent or recover better from similar attacks. "A significant cyber incident is really an opportunity; because it's an opportunity to focus on the core issues that led to these cyber incidents," said Anne Neuberger, deputy national security advisor for cyber and emerging technology at the White House, speaking at the UK National Cyber Security Centre's (NCSC) CYBERUK 21 virtual conference. Neuberger said that whether it's something like the SolarWinds sophisticated supply chain attack or the Colonial Pipeline ransomware incident, "we know that vulnerabilities across software and hardware can bring on larger concerns", but that looking at the core issues can help everyone improve their security.

Microsoft Remote Desktop Protocol (RDP) Allegedly Has An Alarming Active Vulnerability
The Remote Desktop Protocol (RDP) is an incredibly useful feature used by likely millions of people every day. Considering it is free and preinstalled from Microsoft, it beats out most other Windows-based remote desktop software with ease. This, however, does not give it a free pass from having flaws; however, as a security researcher has discovered his password in cleartext within the RDP service’s memory. Researcher Jonas Lykkegård of the Secret Club, a group of hackers, seems to stumble across interesting things from time to time. He recently posted to Twitter about finding a password in cleartext in memory after using the RDP service. It seems he could not believe what he had found, as he tested it again and produced the same results using a new local account.
Amazon’s Ring Is The Largest Civilian Surveillance Network The US Has Ever Seen
In a 2020 letter to management, Max Eliaser, an Amazon software engineer, said Ring is “simply not compatible with a free society”. We should take his claim seriously. Ring video doorbells, Amazon’s signature home security product, pose a serious threat to a free and democratic society. Not only is Ring’s surveillance network spreading rapidly, it is extending the reach of law enforcement into private property and expanding the surveillance of everyday life. What’s more, once Ring users agree to release video content to law enforcement, there is no way to revoke access and few limitations on how that content can be used, stored, and with whom it can be shared.
Ransomware Attacks Are Spiking. Is Your Company Prepared?
With the migration to remote work over the last year, cyber attacks have increased exponentially. We saw more attacks of every kind, but the headline for 2020 was ransom attacks, which were up 150% over the previous year. The amount paid by victims of these attacks increased more than 300% in 2020. Already 2021 has seen a dramatic increase in this activity, with high-profile ransom attacks against critical infrastructure, private companies, and municipalities grabbing headlines on a daily basis. The amount of ransom demanded also has significantly increased this year, with some demands reaching tens of millions of dollars. And the attacks have become more sophisticated, with threat actors seizing sensitive company data and holding it hostage for payment.

Top Cyber Stories of the Last Week
Ransomware Gangs Made At Least $350 Million In 2020
Ransomware gangs made at least $350 million in ransom payments last year, in 2020, blockchain analysis. The figure was compiled by tracking transactions to blockchain addresses linked to ransomware attacks. Although Chainalysis possesses one of the most complete sets of data on cryptocurrency-related cybercrime, the company said its estimate was only a lower bound of the true total due.
https://www.zdnet.com/article/ransomware-gangs-made-at-least-350-million-in-2020/
Home Working Increases Cyber Security Fears
"We see tens of different hacking attacks every single week. It is never ending."A senior computer network manager says they are bombarded from all directions. "We see everything," he says. "Staff get emails sent to them pretending to be from the service desk, asking them to reset their log-in passwords. "We see workers being tricked into downloading viruses from hackers demanding ransoms, and we have even had employees sent WhatsApp messages pretending to be from the CEO, asking for money transfers.
https://www.bbc.co.uk/news/business-55824139
3.2 Billion Emails And Passwords Exposed Online
A whopping 3.2 billion password-username pairs are up for grabs in an unnamed online hacking forum. But don't panic — the data is nothing new. It's a compilation of stolen credentials from dozens of old data breaches, some going back ten years. That doesn't mean you shouldn't be aware that your old passwords are floating out there. Yes, your passwords, and ours too. Pretty much anyone who's ever created more than three online accounts has had a password compromised by now.
https://www.tomsguide.com/news/3-2-billion-passwords-leaked
Account Takeover Attacks Spiked In 2020
Occurring whenever a bad actor can steal login credentials and seize control of an online account, takeover attacks rose from 34% of fraud detected in 2019 to 54% by the end of December 2020. Other methods of fraud were blips on the radar compared to account takeovers: The next most popular method, at just 16% of detected fraud, was money laundering/mule transactions, followed by new account fraud (14%), and a mere 12% of instances used remote access or hacking tools to accomplish their goals.
https://www.techrepublic.com/article/account-takeover-attacks-spiked-in-2020-kaspersky-says/
30% Of “Solarwinds Hack” Victims Didn’t Actually Use Solarwinds
When security last week that it had been targeted by the same attacker that compromised SolarWinds' Orion software, it noted that the attack did not use SolarWinds itself. According to Malwarebytes, the attacker had used "another intrusion vector" to gain access to a limited subset of nearly a third of the organizations attacked had no direct connection to SolarWinds.
Data Leakage Attacks Saw Huge Rise In 2020
The number of data leakage incidents grew by an “unprecedented” rate in 2020, a new report from Imperva argues. Through online means alone, not counting leaks caused by lost hardware or word of mouth, Imperva researchers tracked a 93 percent rise. By the end of the year, Imperva had identified a total of 1.7 million leaks, with the the number growing even faster in the second half of the year. Between Q3 and Q4, there was a 47 percent increase.
https://www.itproportal.com/news/data-leakage-attacks-saw-huge-rise-in-2020/
Automated Tools Increasingly Used to Launch Cyber Attacks
Cyber-criminals are increasingly making use of automation and bots to launch attacks, according to a new analysis. revealed that over half (54%) of all cyber-attacks it blocked in November and December were web application attacks which involved the use of automated tools. The most prevalent form was fuzzing attacks, making up around one in five (19.5%). This uses automation to detect and exploit the points at which applications break. This was followed by injection attacks (12%), in which cyber-criminals make use of automation tools such as sqlmap to gain access to applications.
https://www.infosecurity-magazine.com/news/automated-tools-launch-cyber/
A Second SolarWinds Hack Deepens Third-Party Software Fears
It’s been more than two months since revelations that alleged Russia-backed hackers broke into the IT management firm SolarWinds and used that access to launch a massive software supply chain attack. It now appears that Russia was not alone; Reuters reports that suspected Chinese hackers independently exploited a different flaw in SolarWinds products last year at around the same time, apparently hitting the US Department of Agriculture's National Finance Center.
https://www.wired.com/story/solarwinds-hack-china-usda/
93% Of Workers Overshare Online, Causing Security Risks
Reveals just how much, and how often, people divulge about their lives online and how attackers take advantage of it. With insights from both professionals and hackers, the report explores how cybercriminals use an abundant and seemingly cheap resource — the personal information people share on social media and in out-of-office alerts — to craft social engineering attacks.
https://www.helpnetsecurity.com/2021/02/03/workers-overshare-online/
Is There A Widening Gulf Between You And Your Remote Workers? Yes – And It’s Security Shaped
It’s been almost a year since large parts of the workforce beat a hasty retreat from their offices, and began a mass experiment in working from home, often courtesy of Microsoft 365. And after 12 or so months, it’s safe to say that the case for productive remote working has been proved, and that many workers will continue to do so even when the all clear sounds. But is there a question as to whether remote working is as secure as the traditional, office bound, hard perimeter setup? Well, yes, and it’s fair to say the jury is still very much out.

Travelex paid $2.3M in Bitcoin to get its systems back from hackers
Travelex paid hackers $2.3 million worth of Bitcoin to regain access to its computer systems after a devastating ransomware attack on New Year’s Eve.
The London-based company said it decided to pay the 285 BTC based on the advice of experts, and had kept regulators and partners in the loop throughout the recovery process.
Although Travelex, which manages the world’s largest chain of money exchange shops and kiosks, did confirm the ransomware attack when it happened, it hadn’t yet disclosed a Bitcoin ransom had been paid to restore its systems.
Travelex previously blamed the attack on malware known as Sodinokibi, a ‘Ransomware-as-a-Service’ tool-kit that has recently begun publishing data stolen from companies that don’t pay up.
Travelex‘ operations were crippled for almost all of January, with its public-facing websites, app, and internal networks completely offline. It also reportedly interrupted cash deliveries to major banks in the UK, including Barclays and Lloyds.
At the time, BBC claimed that Travelex‘ attackers had demanded $6 million worth of Bitcoin to unlock its systems.
Zoom sets up CISO Council and hires ex-CSO of Facebook to clean up its privacy mess
The ongoing coronavirus pandemic has seen people relying on work collaboration apps like Teams and Slack to talk to others or conduct meetings. Zoom, in particular, has seen incredible growth over the past few weeks but it came at a cost. The company has been under a microscope after various researchers discovered a number of security flaws in the app. To Zoom’s credit, the company responded immediately and paused feature updates to focus on security issues.
The company announced that it’s taking help from CISOs to improve the security and patch the flaws in the app. Zoom will be taking help from CISOs from HSBC, NTT Data, Procore, and Ellie Mae, among others. Moreover, the company is also setting up an Advisory Board that will include security leaders from VMware, Netflix, Uber, Electronic Arts, and others. Lastly, the company has also asked Alex Stamos, ex-CSO of Facebook to join as an outside advisor. Alex is a well-known personality in the cybersecurity world who left Facebook after an alleged conflict of interest with other executives about how to address the Russian government’s use of its platform to spread disinformation during the 2016 U.S. presidential election.

Researchers discover IoT botnet capable of launching various DDoS attacks
Cyber security researchers have found a new botnet comprised of more than a thousand IoT devices, capable of launching distributed denial of service (DDoS) attacks.
According to a report, researchers have named the botnet Dark Nexus, and believe it was created by well-known malware developer greek.Helios - a group that has been selling DDoS services and botnet code for at least the past three years.
Analysing the botnet through a honeypot, the researchers found it is comprised of 1,372 bots, but believe it could grow extremely quickly.
Dark Nexus is based on Mirai and Qbot, but has seen some 40 iterations since December 2020, with improvements and new features added almost daily.

Microsoft: Cyber-Criminals Are Targeting Businesses Through Vulnerable Employees
Microsoft has warned that cyber-criminals are preying on people’s vulnerable psychological states during the COVID-19 pandemic to attack businesses. During a virtual press briefing, the multinational technology company provided data showing how home working and employee stress during this period has precipitated a huge amount of COVID-19-related attacks, particularly phishing scams.
Working from home at this time is very distracting for a lot of people, particularly if they are looking after children. Additionally, many individuals are in a stressful state with the extra pressures and worries as a result of COVID-19. This environment is providing new opportunities for cyber-criminals to operate.
“We’re seeing a significant increase in COVID-related phishing lures for our customers,” confirmed Microsoft. “We’re blocking roughly 24,000 bad emails a day with COVID-19 lures and we’ve also been able to see and block through our smart screen 18,000 malicious COVID-themed URLs and IP addresses on a single day, so the volume of attacks is quite high.”

Shadow IT Represents Major #COVID19 Home Working Threat
Rising threat levels and remote working challenges stemming from the COVID-19 pandemic are putting increased pressure on IT security professionals, according to new data.
A poll of over 400 respondents from global organisations with over 500 employees was conducted to better understand the current challenges facing security teams.
It revealed that 71% of security professionals had reported an increase in security threats or attacks since the start of the virus outbreak. Phishing (55%), malicious websites (32%), malware (28%) and ransomware (19%) were cited as the top threats.
These have been exacerbated by home working challenges, with 95% of respondents claiming to be under new pressures.
Top among these was providing secure remote access for employees (56%) and scalable remote access solutions (55%). However, nearly half (47%) of respondents complained that home workers using shadow IT solutions represented a major problem.
These challenges are only going to grow, according to the research.

'Unkillable' Android malware gives hackers full remote access to your phone
Security experts are warning Android users about a particularly nasty strain of malware that's almost impossible to remove.
A researcher has written a blog post explaining how the xHelper malware uses a system of nested programs, not unlike a Russian matryoshka doll, that makes it incredibly stubborn.
The xHelper malware was first discovered last year, but the researcher has only now established exactly how it gets its claws so deeply into your device, and reappears even after a system restore.
Although the Google Play Store isn't foolproof, unofficial third party app stores are much more likely to harbour malicious apps. App-screening service Google Play Protect blocked more than 1.9 million malware-laced app installs last year, including many side-loaded or installed from unofficial sources, but it's not foolproof.
xHelper is often distributed through third-party stores disguised as a popular cleanup or maintenance app to boost your phone's performance, and once there, is amazingly stubborn.
Decade of the RATs (Remote Access Trojan): Novel APT Attacks Targeting Linux, Windows and Android
BlackBerry researchers have released a new report that examines how five related APT groups operating in the interest of the Chinese government have systematically targeted Linux servers, Windows systems and Android mobile devices while remaining undetected for nearly a decade.
The report comes on the heels of the U.S. Department of Justice announcing several high-profile indictments from over 1,000 open FBI investigations into economic espionage as part of the DOJ’s China Initiative.
The BlackBerry report, titled Decade of the RATs: Cross-Platform APT Espionage Attacks Targeting Linux, Windows and Android, examines how APTs have leveraged the “always on, always available” nature of Linux servers to establish a “beachhead” for operations. Given the profile of the five APT groups involved and the duration of the attacks, it is likely the number of impacted organisations is significant.
The cross-platform aspect of the attacks is also of particular concern in light of security challenges posed by the sudden increase in remote workers. The tools identified in these ongoing attack campaigns are already in place to take advantage of work-from-home mandates, and the diminished number of personnel onsite to maintain security of these critical systems compounds the risks. While the majority of the workforce has left the office as part of containment efforts in response to the Covid-19 outbreak, intellectual property remains in enterprise data centres, most of which run on Linux.
Most large organizations rely on Linux to run websites, proxy network traffic and store valuable data. While Linux may not have the visibility that other front-office operating systems have, it is arguably the most critical where the security of critical networks is concerned. Linux runs nearly all of the top 1 million websites, 75% of all web servers, 98% of the world’s supercomputers and 75% of major cloud service providers (Netcraft, 2019, Linux Foundation, 2020).

Bot traffic fueling rise of fake news and cybercrime
The coronavirus pandemic has disrupted daily life around the world and the WHO recently warned that an overabundance of information about the virus makes it difficult for people to differentiate between legitimate news and misleading information.
At the same time, EU security services have warned that Russia is aggressively exploiting the coronavirus pandemic to push disinformation and weaken Western society through its bot army.
A cyber security firm has been using its bot manager to monitor internet traffic in an attempt to track the “infodemic” that both the WHO and EU security services have issued warnings on.
According to the data, bots have upped their game and organisations in the social media, ecommerce and digital publishing industries have experienced a surge in bad bot traffic following the coronavirus outbreak.
The bots have been found to be executing various insidious activities including spreading disinformation, spam commenting and more. In February, 58.1 percent of bots had the capability to mimic human behaviour. This means that they can disguise their identities, create fake accounts on social media sites and post their masters' propaganda while appearing as a genuine user.
