Black Arrow Cyber Threat Briefing 18 June 2021: Ransomware Now Ranks As UK’s Top Cyber Security Danger; 54% of all employees reuse passwords across accounts; Most Firms Face Second Ransomware Attack After Paying Off First; Bad Cyber Security Behaviours Plaguing The Remote Workforce; VPN Attacks Up Nearly 2000% As Companies Embrace A Hybrid Workplace; Over 65,000 Ransomware Attacks Expected In 2021; Business Leaders Now Feel More Vulnerable To Cyber Attacks
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
Ransomware Now Ranks As UK’s Top Cyber Security Danger
Ransomware hackers are now the biggest cyber security threat in the UK for the majority of individuals and businesses in the region, Lindy Cameron, chief executive of the National Cyber Security Centre (NCSC), said in a speech. “For the vast majority of UK citizens and businesses, and indeed for the vast majority of critical national infrastructure providers and government service providers, the primary key threat is not state actors but cyber criminals,” Cameron said in the speech at the second annual cyber security meeting at the Royal United Services Institute (RUSI), the oldest independent defense and security think tank worldwide.
54% of all employees reuse passwords across multiple work accounts
Results of a study into current attitudes and adaptability to at-home corporate cyber security, employee training, and support in the current global hybrid working era revealed some interesting results. The report surveyed 3,006 employees, business owners, and C-suite executives at large organisations (250+ employees), who have worked from home and use work issued devices in the UK, France and Germany.
According to the findings 54% of all employees use the same passwords across multiple work accounts. 22% of respondents still keep track of passwords by writing them down, including 41% of business owners and 32% of C-level executives.
42% of respondents admit to using work-issued devices for personal reasons daily while working from home. Of these, 29% are using work devices for banking and shopping, and 7% admit to watching illegal streaming services. Senior workers are among the biggest offenders, as 44% of business owners and 39% of C-level executives admit to performing personal tasks on work-issued devices every day since working from home, with 23% of business owners and 15% of C-level respondents using them for illegal streaming/watching TV.
A year after the pandemic began and work-from-home policies were implemented, 37% of all employees across all sectors are yet to receive cyber security training to work from home, leaving businesses largely exposed to evolving risks. 43% of all employees suggest that cyber security isn’t the responsibility of the workforce, with 60% believing this should be handled by IT teams.

VPN Attacks Up Nearly 2000% As Companies Embrace A Hybrid Workplace
In Q1 2021, there was a 1,916% increase in attacks against Fortinet’s SSL-VPN and a 1,527% increase in Pulse Connect Secure VPN. These vulnerabilities allow a threat actor to gain access to a network. Once they are in, they can exfiltrate information and deploy ransomware. “2020 was the era of remote work and as the workforce adjusted, information technology professionals scrambled to support this level of remote activity by enabling a wide variety of remote connectivity methods,” said J.R. Cunningham, CSO at Nuspire. “This added multiple new attack vectors that enabled threat actors to prey on organisations, which is what we started to see in Q1 and are continuing to see today.”

Most Firms Face Second Ransomware Attack After Paying Off First
Most businesses that choose to pay to regain access to their encrypted systems experience a subsequent ransomware attack. And almost half of those that pay up say some or all their data retrieved were corrupted. Some 80% of organisations that paid ransom demands experienced a second attack, of which 46% believed the subsequent ransomware to be caused by the same hackers. Amongst those that paid to regain access to their systems, 46% said at least some of their data was corrupted, according to a survey released Wednesday. The study polled 1,263 security professionals in seven markets worldwide, including 100 in Singapore, as well as respondents in Germany, France, the US, and UK.

Over 65,000 Ransomware Attacks Expected In 2021: Former Cisco CEO
U.S. companies are expected to endure over 65,000 ransomware attacks this year — and that's “a conservative number,” according to John Chambers, former CEO of Cisco Systems. With McDonald’s, JBS, and Colonial Pipeline Co. all recently coming under cyber attacks, Chambers does not foresee an end to the onslaught of cyber security threats anytime soon. He estimated that the number of ransomware attacks in 2021 could end up being as high as 100,000, with each one costing companies an average of $170,000. In the case of Colonial, just one password was needed for hackers to compromise the entire company’s IT infrastructure. This led to Colonial and JBS paying a combined $15 million in ransom against FBI advice.
Business Leaders Now Feel More Vulnerable To Cyber Attacks
Geographically speaking, 55% of US and 49% of UK respondents have experienced the most severe impact to their network security due to these attacks (suggesting that their businesses are more of a target than those in continental Europe) which, in turn, has resulted in a clear majority of respondents (60%) increasing their investment in this area. A sizeable 68% of leaders said their company has experienced a DDoS attack in the last 12 months with the UK (76%) and the US (73%) experiencing a significantly higher proportion compared to 59% of their German and 56% French counterparts. Additionally, over half of the leaders who participated in the survey confirmed that they specifically experienced a DDoS ransom or extortion attack in that time, with a large number of them (65%) targeted at UK companies, compared with the relatively low number in France (38%).

Ransomware Gang Turns To Revenge Porn
At least one ransomware gang has taken a rare and highly invasive step in order to convince its victims to pay: leaking nude images allegedly uncovered as part of their hack of a target company. The news presents an escalation in the world of ransomware and digital extortion, and comes as the U.S. government and other countries discuss new measures to curb the spike in ransomware incidents. Ransomware groups have recently targeted, and in some cases extracted payment from, the Colonial Pipeline Company, meat producer JBS, and the Irish healthcare system. Locking down computers with ransomware can already have a substantial impact on business operations; leaking information on top of that can present victims with another risk. But posting nude images publicly on the internet threatens to make extortion of organisations a much more personal matter.

Bank Of America Spends Over $1 Billion Per Year On Cyber Security
Bank of America CEO Brian Moynihan said Monday that the company has ramped its cyber security spending to over $1 billion a year. “I became CEO 11 and a half years ago, and we probably spent three to $400 million [per year] and we’re up over a billion now,” Moynihan said on CNBC’s “Squawk Box.” “The institutions around us, other institutions and my peers, spend like amounts, and our contracting parties spend like amounts,” he added. “In other words, we cause spending in third parties that provide services to us to protect us in the same way. So there’s a lot of money being spend on this, and I think one of the things our industry has done a great job of is work together.”

Bad Cyber Security Behaviours Plaguing The Remote Workforce
According to the report, younger employees are most likely to admit they cut cyber security corners, with 51% of 16-24 year olds and 46% of 25-34 year olds reporting they’ve used security workarounds. In addition, 39% say the cyber security behaviours they practice while working from home differ from those practiced in the office, with half admitting it’s because they feel they were being watched by IT departments. IT leaders are optimistic about the return to office, with 70% believing staff will more likely follow company security policies around data protection and privacy. However, only 57% of employees think the same.

Black Arrow Cyber Threat Briefing 11 June 2021
Black Arrow Cyber Threat Briefing 11 June 2021: World’s Biggest Meat Producer JBS Pays $11m Ransom; New Type Of Ransomware Could Be 10 Times As Dangerous; Lewd Phishing Lures Aimed At Business Explode; UK Schools Forced To Shut Following Ransomware; COVID-19 Has Transformed Work, But Cyber Security Is Not Keeping Pace; Colonial Pipeline Ransomware Attack Stemmed From Old VPN Password; Evil Corp Rebrands Ransomware To Escape Sanctions; Billions Of Passwords Leaked Online From Past Data Breaches
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.
