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
World’s Biggest Meat Producer JBS Pays $11m Cyber Crime Ransom
JBS, the world’s biggest meat processor, has paid an $11m (£7.8m) ransom after a cyber attack shut down operations, including abattoirs in the US, Australia and Canada. While most of its operations have been restored, the Brazilian-headquartered company said it hoped the payment would head off any further complications including data theft. JBS, which supplies more than a fifth of all beef in the US, reportedly made the payment in bitcoin.
Jackware: A New Type Of Ransomware Could Be 10 Times As Dangerous
Between the attacks on Colonial Pipeline and JBS, which disrupted nearly half of the East Coast’s gasoline supply for a week and threatened 20% of the U.S. meat market, respectively, consumers are finally experiencing the first physical impacts to their daily lives from cyber attacks. As bad as these attacks are, they could get a lot worse. Cyber criminals are constantly evolving, and what is keeping many security professionals up at night is the growing risk of “jackware” — a new type of ransomware that could be 10 times more dangerous because instead of encrypting Windows computers and servers. Jackware hijacks the actual physical devices and machines that make modern life possible. It’s only a matter of when we will see these attacks happen
Lewd Phishing Lures Aimed At Business Explode
Attackers have amped up their use of X-rated phishing lures in business email compromise (BEC) attacks. A new report found a stunning 974-percent spike in social-engineering scams involving suggestive materials, usually aimed at male-sounding names within a company. The Threat Intelligence team with GreatHorn made the discovery and explained it’s not simply libido driving users to click on these suggestive scams. Instead, these emails popping up on people’s screens at work are intended to shock the user, opening the door for them to make a reckless decision to click. It’s a tactic GreatHorn called “dynamite phishing.”

UK Schools Forced To Shut Following Critical Ransomware Attack
Two schools in the south of England have been forced to temporarily close their doors after a ransomware attack that encrypted and stole sensitive data. The Skinners' Kent Academy and Skinners' Kent Primary School were attacked on June 2, according to a statement on the trust’s website which said it is currently working with third-party security experts, the police, and the National Cyber Security Centre (NCSC). It revealed that on-premises servers were targeted at the Tunbridge Well-based schools. As student and staff emergency contact details, medical records, timetables, and registers were encrypted by the attackers, the decision was taken to close on Monday.

Emerging Ransomware Targets Dozens Of Businesses Worldwide
An emerging ransomware strain in the threat landscape claims to have breached 30 organisations in just four months since it went operational by riding on the coattails of a notorious ransomware syndicate. First observed in February 2021, "Prometheus" is an offshoot of another well-known ransomware variant called Thanos, which was previously deployed against state-run organisations in the Middle East and North Africa last year. The affected entities are believed to be government, financial services, manufacturing, logistics, consulting, agriculture, healthcare services, insurance agencies, energy and law firms in the U.S., U.K., and a dozen more countries in Asia, Europe, the Middle East, and South America.

COVID-19 Has Transformed Work, But Cyber Security Is Not Keeping Pace, Report Finds
An international survey of tech professionals from the Thales Group finds some bleak news for the current state of data security: the COVID-19 pandemic has upended cyber security norms, and security teams are struggling to keep up. The problems appear to be snowballing; lack of preparation has led to a scramble resulting in poor data protection practices, outdated security infrastructure not receiving needed overhauls, a jumble of new systems that only make matters worse and priority misalignment between security teams and leadership.
Colonial Pipeline Ransomware Attack Was The Result Of An Old VPN Password
It took only one dusty, no-longer-used password for the DarkSide cyber criminals to breach the network of Colonial Pipeline Co. last month, resulting in a ransomware attack that caused significant disruption and remains under investigation by the U.S. government and cyber security experts. Attackers used the password to a VPN account that was no longer in use but still allowed them to remotely access Colonial Pipeline’s network, Charles Carmakal, senior vice president at FireEye’s cyber security consulting firm Mandiant, told Bloomberg in an interview, according to a published report on the news outlet’s website.

Evil Corp Rebrands Ransomware To Escape Sanctions
Threat actors behind a notorious Russian cyber crime group appear to have rebranded their ransomware once again in a bid to escape US sanctions prohibiting victims from paying them. Experts took to Twitter to point out that a leak site previously run by the Babuk group, which famously attacked Washington DC’s Metropolitan Police Department (MPD), had rebranded to “PayloadBin.” The Babuk group claimed that it was shutting down its affiliate model for encrypting victims and moving to a new model back in April. A ‘new’ ransomware variant with the same name has also been doing the rounds of late, but according to CTO of Emsisoft, Fabian Wosar, it’s nothing more than a copycat effort by Evil Corp.

Billions Of Passwords Leaked Online From Past Data Breaches
A list of leaked passwords discovered on a hacker forum may be one of the largest such collections of all time. A 100GB text file leaked by a user on a popular hacker forum contains 8.4 billion passwords, likely gathered from past data breaches.
