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
Ryuk gang estimated to have made more than $150 million from ransomware attacks
In a joint report published today, threat intel company Advanced Intelligence and cyber security firm HYAS said they tracked payments to 61 Bitcoin addresses previously attributed and linked to Ryuk ransomware attacks. "Ryuk receives a significant amount of their ransom payments from a well-known broker that makes payments on behalf of the ransomware victims," the two companies said. "These payments sometimes amount to millions of dollars and typically run in the hundreds of thousands range."
China's APT hackers move to ransomware attacks
Security researchers investigating a set of ransomware incidents at multiple companies discovered malware indicating that the attacks may be the work of a hacker group believed to operate on behalf of China. Although the attacks lack the sophistication normally seen with advanced threat actors, there is strong evidence linking them to APT27, a group normally involved in cyber espionage campaigns, also known as TG-3390, Emissary Panda, BRONZE UNION, Iron Tiger, and LuckyMouse.

SolarWinds hack: Amid hardened security, attackers seek softer targets
Reported theories by SolarWinds hack investigators that federal agencies and private companies were too busy focusing on election security to recognize vulnerabilities tied to the software supply chain are unfair and misleading. And yet, those same experts acknowledge that such accusations offer an important cyber security lesson for businesses: organizations must ensure that their entire attack surface receives attention.
Hackney Council files including alleged passport documents leaked online after cyber attack
The council in East London was hit by what it described as a "serious cyber attack" in October. It reported itself to the data watchdog due to the risk criminals accessed staff and residents' data. The council said it was working with the UK's National Cyber Security Centre (NCSC) and the Ministry of Housing to investigate and understand the impact of the incident.
PayPal users targeted in new SMS phishing campaign
Now, at first glance the message may not seem all that suspicious since PayPal may, in fact, impose limits on sending and withdrawing money. The payment provider usually does so when it suspects that an account has been accessed by a third party without authorization, when it has detected high-risk activities on an account, or when a user has violated its Acceptable Use Policy. However, in this case it really is a case of SMS-borne phishing, also known as Smishing. If you click on the link, you will be redirected to a login phishing page that will request your access credentials. Should you proceed to “log in”, your credentials will be sent to the scammers behind the ruse and the fraudulent webpage will attempt to gather further information, including the full name, date of birth address, and bank details.

SolarWinds, top executives hit with class action lawsuit over Orion software breach
SolarWinds and some of its top executives have been hit with a class action lawsuit by stockholders, who allege the company lied and materially misled them about security practices leading up to a massive breach of its Orion management software that has reverberated throughout the public and private sector.
The rise of cyber-mercenaries poses a growing threat for both governments and companies
These days, 21st century mercenaries are as likely to be seated behind a computer screen, wreaking havoc for their paymasters’ enemies as slugging it out on a real-world battlefield. But the rapid rise of cyber-mercenaries - or Private Sector Offensive Actors (PSOAs) - is vexing some of the biggest names in the global technology industry, and for good reason. Globally, the cyber security industry is already vast, raking in an estimated $156bn in revenues in 2019. It is set to nearly double in size by 2027.
Declutter Your Devices to Reduce Security Risks
Everyone should set aside time to review what they’ve installed on their various devices—typically apps, but that can also include games and addons. In fact, this should be an annual cleaning, at minimum.
You’re not just doing this because you want your device to look good. That’s one benefit you get from cleaning up your digital life, but it’s not the most important one. You’re also doing this to bolster your digital security. Yes, security.
