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
Many Organisations Lack Basic Cyber Hygiene Despite High Confidence In Their Cyber Defences
A new report released this week analysed IT security leaders’ perceived threat of ransomware attacks and the maturity of their cyber security defences. The report found that while 81% of those surveyed consider their security to be above average or exceptional, many lack basic cyber hygiene – 41% lack a password complexity requirement, one of the cheapest, easiest forms of protection, and only 55.6% have implemented multi-factor authentication (MFA). https://www.helpnetsecurity.com/2021/10/21/organizations-cyber-hygiene/
83% Of Ransomware Victims Paid Ransom
A new survey of 300 US-based IT decision-makers found that 64% have been victims of a ransomware attack in the last 12 months, and 83% of those attack victims paid the ransom demand.
Cybersecurity company ThycoticCentrify released its "2021 State of Ransomware Survey & Report" on Tuesday, featuring the insights of IT leaders who have dealt with ransomware attacks over the last year. https://www.zdnet.com/article/83-of-ransomware-victims-paid-ransom-survey/
Ransomware Affected 72% Of Organisations In Past Year
72% of organisations were affected by ransomware at least once within the past twelve months, with 18% impacted more than six times in the past year. Organizations of all sizes were affected nearly to the same extent, with the exception of those with more than 25,000 employees. https://venturebeat.com/2021/10/20/report-ransomware-affected-72-of-organizations-in-past-year/
Ransomware: Looking For Weaknesses In Your Own Network Is Key To Stopping Attacks
Ransomware is a major cybersecurity threat to organisations around the world, but it's possible to reduce the impact of an attack if you have a thorough understanding of your own network and the correct protections are in place.
While the best form of defence is to stop ransomware infiltrating the network in the first place, thinking about how the network is put together can help slow down or stop the spread of an attack, even if the intruders have successfully breached the perimeter. https://www.zdnet.com/article/ransomware-looking-for-weaknesses-in-your-own-network-is-key-to-stopping-attacks/
A Hacker Warns: Give Up Trying To Keep Me Out — And Focus On Your Data
There is a misconceived notion that the security arena is a battlefield. It is not. It is a chess board and requires foresight and calculated pawn placement to protect the king — your data. If your main focus lies on keeping hackers out of your environment, then it’s already check mate. Your mission should be to buy time, slow hackers down and ultimately contain an attack.
Businesses must therefore make it as hard as possible for adversaries to exploit the relationships that allow them to move laterally through the corporate network. They can do this by distrusting anyone within their data’s environment and repeatedly corroborating that all users are who they say they are, and that they act like it too. That last part is crucial, because while identities are easy to compromise and imitate, behaviours are not. https://www.ft.com/content/93cec8b6-3fe9-4e9e-800a-62e13a0e2eac
Cyber Risk Trends Driving The Surge In Ransomware Incidents
During the COVID-19 crisis, another outbreak took place in the cyber space: a digital pandemic driven by ransomware. In a recent report, Allianz Global Corporate & Specialty (AGCS) analyzes the latest risk developments around ransomware and outlines how companies can strengthen their defenses with good cyber hygiene and IT security practices
The increasing frequency and severity of ransomware incidents is driven by several factors:
· Growing number of different attack patterns such as double and triple extortion campaigns
· Criminal business model around ‘ransomware as a service’ and cryptocurrencies
· Recent skyrocketing of ransom demands
· Rise of supply chain attacks.
Not all attacks are targeted. Criminals also adopt a scattergun approach to exploit those businesses that aren’t addressing or understanding the vulnerabilities they may have. Businesses must understand the need to strengthen their controls.
Cyber intrusion activity globally jumped 125% in the first half of 2021 compared to the previous year, according to Accenture, with ransomware and extortion operations one of the major contributors behind this increase. According to the FBI, there was a 62% increase in ransomware incidents in the US in the same period that followed an increase of 20% for the full year 2020. https://www.helpnetsecurity.com/2021/10/18/five-ransomware-trends/
US Ransomware Victims Paid $600 Million to Hackers in 1H of 2021
US Ransomware victims coughed up nearly $600 million to cyber hijackers in the first six months of 2021, further stamping cyber extortionists as an “increasing threat” to the U.S. financial, business and public sectors, a recent report released by the Treasury Department said.
Data gathered by the Financial Crimes Enforcement Network (FinCEN) derived from financial institutions’ Suspicious Activity Reports (SARs) revealed that the 635 reports filed for the first six months of this year is already 30 percent greater than the 487 filed for all of last year. Some 458 financial transitions have been reported as of June 30, 2021 with the total value of suspicious activity reported in ransomware-related SARs during the first six months of 2021 amounting to $590 million, or 42 percent more than the $416 million filed for all of 2020. https://www.msspalert.com/cybersecurity-research/victims-paid-600-millon-1h-2021/
Hacking Group Created Fake Cyber Security Companies To Hire Experts And Involve Them In Ransomware Attacks Tricking Them Of Conducting A Pentest
The FIN7 hacking group is attempting to enter in the ransomware business and is doing it with an interesting technique. The gang is creating fake cyber security companies that hire experts requesting them to carry out pen testing attacks under the guise of pentesting activities.
FIN7 is a Russian criminal group that has been active since mid-2015, it focuses on restaurants, gambling, and hospitality industries in the US to harvest financial information that was used in attacks or sold in cybercrime marketplaces.
One of the companies created by the cyber criminal organizations with this purpose is Combi Security, but researchers from Gemini Advisory discovered other similar organizations by analyzing the site of another fake cybersecurity company named Bastion Security. https://securityaffairs.co/wordpress/123673/cyber-crime/fin7-fake-cybersecurity-firm.html
Nearly Three-Quarters of Organisations Victimized by DNS Attacks in Past 12 Months
Domain name system (DNS) attacks are impacting organizations at worrisome rates. According to a new survey from the Neustar International Security Council (NISC) conducted in September 2021, 72% of study participants reported experiencing a DNS attack within the last 12 months. Among those targeted, 61% have seen multiple attacks and 11% said they have been victimized regularly. While one-third of respondents recovered within minutes, 58% saw their businesses disrupted for more than an hour, and 14% took several hours to recover. https://www.darkreading.com/attacks-breaches/nearly-three-quarters-of-organizations-victimized-by-dns-attacks-in-past-12-months
Cyber Crime Matures As Hackers Are Forced To Work Smarter
An analysis of 500 hacking incidents across a wide range of industries has revealed trends that characterize a maturity in the way hacking groups operate today.
Researchers at Kaspersky have focused on the Russian cybercrime underground, which is currently one of the most prolific ecosystems, but many elements in their findings are common denominators for all hackers groups worldwide.
One key finding of the study is that the level of security on office software, web services, email platforms, etc., is getting better, browser vulnerabilities have reduced in numbers, and websites are not as easy to compromise and use as infection vectors today.
This has resulted in making web infections too difficult to pursue for non-sophisticated threat groups.
The case is similar with vulnerabilities, which are fewer and more expensive to discover.
Instead, hacking groups are waiting for a PoC or patch to be released, and then use that information to create their own exploits. https://www.bleepingcomputer.com/news/security/cybercrime-matures-as-hackers-are-forced-to-work-smarter/
Hackers Stealing Browser Cookies to Hijack High-Profile YouTube Accounts
Since at least late 2019, a network of hackers-for-hire have been hijacking the channels of YouTube creators, luring them with bogus collaboration opportunities to broadcast cryptocurrency scams or sell the accounts to the highest bidder.
That's according to a new report published by Google's Threat Analysis Group (TAG), which said it disrupted financially motivated phishing campaigns targeting the video platform with cookie theft malware. The actors behind the infiltration have been attributed to a group of hackers recruited in a Russian-speaking forum. https://thehackernews.com/2021/10/hackers-stealing-browser-cookies-to.html

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
The Human Element Is the Weakest Link
Within the last week, Facebook has become the subject of a whistleblowing campaign featuring thousands of documents alleging malpractice. Despite their size and expected security controls, these documents have been exfiltrated without detection, lending credence to the idea of the insider threat. https://www.darkreading.com/risk/the-human-element-is-the-weakest-link
Ransomware is the Biggest Cyber Threat to Business But Most Firms Still Aren't Ready for It
Ransomware is still the most significant cyber security threat facing organisations – ranging from critical national infrastructure providers and large enterprises to schools and local businesses – but it's a threat that can be countered. https://www.zdnet.com/article/ransomware-is-now-the-most-urgent-cyber-threat-to-business-but-most-firms-arent-ready-for-it/
Most Known Ransomware Targets Windows Devices
Recently conducted research shows that 95% of identified ransomware is targeting Windows machines. Furthermore, the stats show that Israel are submitting by far the most ransomware samples, followed by South Korea, Vietnam, and China, with the UK in 10th place. https://www.theregister.com/2021/10/14/googles_virustotal_malware/
67% of Organisations Have Been Hit by Ransomware at Least Once
A recent report found that two-thirds of surveyed organizations have suffered a ransomware attack, with about half having been hit multiple times, and 16% having been hit three or more times. https://threatpost.com/podcast-67-percent-orgs-ransomware/175339/
Russian Cyber Crime Gang Targets Finance Firms With Stealthy Macros
A new phishing campaign dubbed MirrorBlast is deploying weaponized Excel documents that are extremely difficult to detect to compromise financial service organizations. The most notable feature of MirrorBlast is the low detection rates of the campaign's malicious Excel documents by security software, putting firms that rely solely upon detection tools at high risk. https://www.bleepingcomputer.com/news/security/russian-cybercrime-gang-targets-finance-firms-with-stealthy-macros/
70% of Businesses Can’t Ensure the Same Level of Protection for Every Endpoint
Recent research found that 86% of UK respondents believe it is not possible to fully prevent ransomware and malware attacks from compromising their organisations. It also found that the rise in the number of endpoints that businesses need to protect continues to be a key source of risk exposure. https://www.helpnetsecurity.com/2021/10/15/endpoint-protection-level/
Over 90% of Firms Suffered Supply Chain Breaches Last Year
A recent survey polled 1200 IT and procurement leaders responsible for supply chain and cyber risk management. Those polled came from global companies with 1,000+ employees and were used to compile its report: Managing Cyber Risk Across the Extended Vendor Ecosystem. The report revealed the average number of breaches experienced in the past 12 months grew from 2.7 in 2020 to 3.7 in 2021 – a 37% year-on-year increase. https://www.infosecurity-magazine.com/news/90-firms-supply-chain-breaches/
Cyber Security Shortcomings Exposed By The Pandemic
According to a survey by SecureAge, 48% of businesses have experienced a cyber breach during the COVID-19 pandemic and another 8% ‘were not sure’. In addition, 16% of employees said they personally had to deal with a cyber security incident during the same period. https://www.helpnetsecurity.com/2021/10/13/cybersecurity-shortcomings/
6 Things to Know About 'Killware,' Cyber Security's Next Big Threat
Threat actors are adopting a “killware” cyber model, which launches attacks on critical infrastructure with the intent to cause harm. Alejandro Mayorkas, secretary for Homeland Security, told USA Today he is worried about killware because it has the potential to kill. Hackers breached a water system in February this year, which was considered an unsuccessful attempt to distribute contaminated water to residents of Florida. "[The] attack was not for financial gain but rather purely to do harm,” he said. https://www.beckershospitalreview.com/cybersecurity/6-things-to-know-about-killware-cybersecurity-s-next-big-threat.html
2021 Nastiest Malware: Here to Stay and Ever Evolving
This year was yet another year with COVID-19 and malware running rampant in the headlines. Be it in person or online, the world is still struggling in the fight against viruses. This year took another turn for the worse when attacks on critical infrastructure and supply chains became a hot trend. https://www.helpnetsecurity.com/2021/10/12/nastiest-malware-2021/

Black Arrow Cyber Threat Briefing 04 December 2020
Black Arrow Cyber Threat Briefing 4 December 2020: Covid vaccine supply chain targeted by hackers; Criminals Favour Ransomware and BEC; Bank Employee Sells Personal Data of 200,000 Clients; 2020 Pandemic changing short- and long-term approaches to risk; Cyber risks take the fun out of connected toys; Remote Workers Admit Lack of Security Training
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
Covid vaccine supply chain targeted by hackers, say security experts
Cyber attackers have targeted the cold supply chain needed to deliver Covid-19 vaccines, according to a report detailing a sophisticated operation likely backed by a nation state.
The hackers appeared to be trying to disrupt or steal information about the vital processes to keep vaccines cold as they travel from factories to hospitals and doctors’ offices.
https://www.ft.com/content/9c303207-8f4a-42b7-b0e4-cf421f036b2f
Criminals to Favour Ransomware and BEC Over Breaches in 2021
The era of the mega-breach may be coming to an end as cyber-criminals eschew consumers’ personal data and focus on phishing and ransomware.
Cyber-criminals are relying less on stolen personal information and more on “poor consumer behaviors” such as password reuse to monetize attacks.
https://www.infosecurity-magazine.com/news/criminals-favor-ransomware-bec/
Bank Employee Sells Personal Data of 200,000 Clients
South Africa–based financial services group Absa has stated that one of its employees sold the personal information of 200,000 clients to third parties.
The group confirmed on Wednesday that the illegal activity had occurred and that 2% of Absa's retail customer base had been impacted.
The employee allegedly responsible for it was a credit analyst who had access to the group's risk-modeling processes.
Data exposed as a result of the security incident included clients' ID numbers, addresses, contact details, and descriptions of vehicles that they had purchased on finance.
https://www.infosecurity-magazine.com/news/bank-employee-sells-personal-data/
LastPass review: Still the leading password manager, despite security history
"'Don't put all your eggs in one basket' is all wrong. I tell you 'put all your eggs in one basket, and then watch that basket,'" said industrialist Andrew Carnegie in 1885. When it comes to privacy tools, he's usually dead wrong. In the case of password managers, however, Carnegie is usually more dead than wrong. To wit, I have been using LastPass so long I don't know when I started using LastPass and, for now, I've got no reason to change that.
The most significant security innovations of 2020
Who gets access? That is the question that drives every security measure and innovation that’s landed on PopSci’s annual compendium since we launched the category in 2008. Every year, that question gets bigger and bigger. In 2020, the world quaked under a global pandemic that took 1.4 million lives, the US saw a rebirth in its civil rights movement, and a spate of record-breaking wildfires forced entire regions to evacuate. And those are just the new scares. A buildup of angst against ad trackers and app snooping led to major changes in hardware and software alike. It was a year full of lessons, nuances, and mini revolutions, and we strive to match that with our choices.
https://www.popsci.com/story/technology/most-important-security-innovations-2020/
2020 security priorities: Pandemic changing short- and long-term approaches to risk
Security planning and budgeting is always an adventure. You can assess current risk and project the most likely threats, but the only real constant in cybersecurity risk is its unpredictability. Layer a global pandemic on top of that and CISOs suddenly have the nearly impossible task of deciding where to request and allocate resources in 2021.
Show how the COVID pandemic has changed what security focuses on now and what will drive security priorities and spending in 2021. Based on a survey of 522 security professionals from the US, Asia/Pacific and Europe, the study reveals how the pandemic has changed the way organizations assess risk and respond to threats—permanently.
Cyber risks take the fun out of connected toys
As Christmas approaches, internet-enabled smart toys are likely to feature heavily under festive trees. While some dolls of decades past were only capable of speaking pre-recorded phrases, modern equivalents boast speech recognition and can search for answers online in real time.
Other connected gadgets include drones or cars such as Nintendo’s Mario Kart Live Home Circuit, where players race each other in a virtual world modelled after their home surroundings.
But for all the fun that such items can bring, there is a risk — poorly-secured Internet of Things toys can be turned into convenient tools for hackers.
https://www.ft.com/content/c653e977-435f-4553-8401-9fa9b0faf632
Remote Workers Admit Lack of Security Training
A third of remote working employees have not received security training in the last six months.
400 remote workers in the UK across multiple industries, while 83% have had access to security best practice training and 88% are familiar with IT security policies, 32% have received no security training in the last six months.
Also, 50% spend two or more hours a week on IT issues, and 42% felt they had to go around the security policies of their organization to do their job.
https://www.infosecurity-magazine.com/news/remote-workers-training/
Threats
Ransomware
Delaware County Pays $500,000 Ransom After Outages
A US county is in the process of paying half-a-million dollars to ransomware extorters who locked its local government network, according to reports.
Pennsylvania’s Delaware County revealed the attack last week, claiming in a notice that it had disrupted “portions of its computer network.
“We commenced an immediate investigation that included taking certain systems offline and working with computer forensic specialists to determine the nature and scope of the event. We are working diligently to restore the functionality of our systems,” it said.
https://www.infosecurity-magazine.com/news/delaware-county-pays-500k-ransom/
MasterChef Producer Hit by Double Extortion Ransomware
A multibillion-dollar TV production company has become the latest big corporate name caught out by ransomware, it emerged late last week.
The firm owns over 120 production firms around the world, delivering TV shows ranging from MasterChef and Big Brother to Black Mirror and The Island with Bear Grylls.
In a short update last Thursday, it claimed to be managing a “cyber-incident” affecting the networks of Endemol Shine Group and Endemol Shine International, Dutch firms it acquired in a $2.2bn deal in July.
Although ransomware isn’t named in the notice, previous reports suggest the firm is being extorted.
https://www.infosecurity-magazine.com/news/masterchef-producer-double/
Sopra Steria to take multi-million euro hit on ransomware attack
The company revealed in October that it had been hit by hackers using a new version of Ryuk ransomware.
It now says that the fallout, with various systems out of action, is likely to have a gross negative impact on operating margin of between €40 million and €50 million.
The group's insurance coverage for cyber risks is EUR30 million, meaning that negative organic revenue growth for the year is now expected to be between 4.5% and five per cent (previously between two per cent and four per cent). Free cash flow is now expected to be between €50 million and €100 million (previously between €80 million and €120 million).
BEC
FBI: BEC Scams Are Using Email Auto-Forwarding
The agency notes in an alert made public this week that since the COVID-19 pandemic began, leading to an increasingly remote workforce, BEC scammers have been taking advantage of the auto-forwarding feature within compromised email inboxes to trick employees to send them money under the guise of legitimate payments to third parties.
This tactic works because most organizations do not sync their web-based email client forwarding features with their desktop client counterparts. This limits the ability of system administrators to detect any suspicious activities and enables the fraudsters to send malicious emails from the compromised accounts without being detected, the alert, sent to organizations in November and made public this week, notes.
https://www.bankinfosecurity.com/fbi-bec-scams-are-using-email-auto-forwarding-a-15498
Phishing
Phishing lures employees with fake 'back to work' internal memos
Scammers are trying to steal email credentials from employees by impersonating their organization's human resources (HR) department in phishing emails camouflaged as internal 'back to work' company memos.
These phishing messages have managed to land in thousands of targeted individuals' mailboxes after bypassing G Suite email defences according to stats provided by researchers at email security company Abnormal Security who spotted this phishing campaign.
There is a high probability that some of the targets will fall for the scammers' tricks given that during this year's COVID-19 pandemic most companies have regularly emailed their employees with updates regarding remote working policy changes.
Warning: Massive Zoom phishing targets Thanksgiving meetings
Everyone should be on the lookout for a massive ongoing phishing attack today, pretending to be an invite for a Zoom meeting. Hosted on numerous landing pages, BleepingComputer has learned that thousands of users' credentials have already been stolen by the attack.
With many in the USA hosting virtual Thanksgiving dinners and people in other countries conducting Zoom business meetings, as usual, today is a prime opportunity to perform a phishing attack using Zoom invite lures.
Malware
All-new Windows 10 malware is excellent at evading detection
Security researchers at Kaspersky have discovered a new malware strain developed by the hacker-for-hire group DeathStalker that has been designed to avoid detection on Windows PCs.
While the threat actor has been active since at least 2012, DeathStalker first drew Kaspersky's attention back in 2018 because of its distinctive attack characteristics which didn't resemble those employed by cybercriminals or state-sponsored hackers.
https://www.techradar.com/news/all-new-windows-10-malware-is-excellent-at-evading-detection
New TrickBot version can tamper with UEFI/BIOS firmware
The operators of the TrickBot malware botnet have added a new capability that can allow them to interact with an infected computer's BIOS or UEFI firmware.
The new capability was spotted inside part of a new TrickBot module, first seen in the wild at the end of October, security firms Advanced Intelligence and Eclypsium said in a joint report published today.
The new module has security researchers worried as its features would allow the TrickBot malware to establish more persistent footholds on infected systems, footholds that could allow the malware to survive OS reinstalls.
https://www.zdnet.com/article/new-trickbot-version-can-tamper-with-uefibios-firmware/
Russia-linked APT Turla used a new malware toolset named Crutch
Russian-linked APT group Turla has used a previously undocumented malware toolset, named Crutch, in cyberespionage campaigns aimed at high-profile targets, including the Ministry of Foreign Affairs of a European Union country.
The Turla APT group (aka Snake, Uroburos, Waterbug, Venomous Bear and KRYPTON) has been active since at least 2007 targeting diplomatic and government organizations and private businesses in the Middle East, Asia, Europe, North and South America, and former Soviet bloc nations.
https://securityaffairs.co/wordpress/111813/apt/turla-crutch-malware-platform.html
MacBooks under attack by dangerous malware: What to do
a recent spate of malware attacks targeting macOS of late that installs backdoors to steal sensitive personal information. The security firm discovered that a new malware variant is being used online and backed by a rogue nation-state hacking group known as OceanLotus, which also operates under the name AKTP2 and is based in Vietnam.
The new malware was created by OceanLotus due to the “similarities in dynamic behavior and code” from previous malware connected to the Vietnamese-based hacking group.

The company’s intelligence team said a group called BISMUTH hit government targets in France and Vietnam with relatively conspicuous monero mining trojans this summer. Mining the crypto generated side cash for the group, but it also distracted victims from BISMUTH’s true campaign: credential theft.
Crypto-jacking “allowed BISMUTH to hide its more nefarious activities behind threats that may be perceived to be less alarming because they’re ‘commodity’ malware,” Microsoft concluded. It said the conspicuousness of monero mining fits BISMUTH’s “hide in plain sight” MO.
Microsoft recommended organizations stay vigilant against crypto-jacking as a possible decoy tactic.

'We've heard the feedback...' Microsoft 365 axes per-user productivity monitoring after privacy backlash
If you heard a strange noise coming from Redmond today, it was the sound of some rapid back-pedalling regarding the Productivity Score feature in its Microsoft 365 cloud platform.
Following outcry from subscribers and privacy campaigners, the Windows giant has now vowed to wind back the functionality so that it no longer produces scores for individual users, and instead just summarizes the output of a whole organization. It was feared the dashboard could have been used by bad bosses to measure the productivity of specific employees using daft metrics like the volume of emails or chat messages sent through Microsoft 365.
