Top Cyber Stories of the Last Week

Ransomware Volumes Hit Record Highs As 2021 Wears On

Ransomware has seen a significant uptick so far in 2021, with global attack volume increasing by 151 percent for the first six months of the year as compared with the year-ago half. Meanwhile, the FBI has warned that there are now 100 different strains circulating around the world. From a hard-number perspective, the ransomware scourge hit a staggering 304.7 million attempted attacks. To put that in perspective, the firm logged 304.6 million ransomware attempts for the entirety of 2020.

Ransomware Gangs Recruiting Insiders To Breach Corporate Networks

The LockBit 2.0 ransomware gang is actively recruiting corporate insiders to help them breach and encrypt networks. In return, the insider is promised million-dollar payouts. Many ransomware gangs operate as a Ransomware-as-a-Service, which consists of a core group of developers, who maintain the ransomware and payment sites, and recruited affiliates who breach victims' networks and encrypt devices. Any ransom payments that victims make are then split between the core group and the affiliate, with the affiliate usually receiving 70-80% of the total amount. However, in many cases, the affiliates purchase access to networks from other third-party pentesters rather than breaching the company themselves. With LockBit 2.0, the ransomware gang is trying to remove the middleman and instead recruit insiders to provide them access to a corporate network.

More Than 12,500 Vulnerabilities Disclosed In First Half Of 2021

Two new reports were released, covering data breaches and vulnerabilities in the first half of 2021, finding that there was a decline in the overall number of reported breaches but an increase in the number of vulnerabilities disclosed.  The company's data breach report found that there were 1,767 publicly reported breaches in the first six months of 2021, a 24% decline compared to the same period last year. The number of reported breaches grew in the US by 1.5% while 18.8 billion records were exposed year to date, a 32% decline compared to the 27.8 billion records leaked in the first half of 2020.

New DNS Vulnerability Allows 'Nation-State Level Spying' On Companies

Security researchers found a new class of DNS vulnerabilities impacting major DNS-as-a-Service (DNSaaS) providers that could allow attackers to access sensitive information from corporate networks.

DNSaaS providers (also known as managed DNS providers) provide DNS renting services to other organisations that do not want to manage and secure yet another network asset on their own.

These DNS flaws provide threat actors with nation-state intelligence harvesting capabilities with a simple domain registration.

Constant Review Of Third Party Security Critical As Ransomware Threat Climbs

Enterprises typically would give their third-party suppliers "the keys to their castle" after carrying out the usual checks on the vendor's track history and systems, according to a New York-based Forrester analyst who focuses on security and risk. They believed they had done their due diligence before establishing a relationship with the supplier, but they failed to understand that they should be conducting reviews on a regular basis, especially with their critical systems suppliers. Third-party suppliers should have the ability to deal with irregular activities in their systems and the appropriate security architecture in place to prevent any downstream effects, he added.

Kaseya Ransomware Attack Sets Off Race To Hack Service Providers

A ransomware attack in July that paralyzed as many as 1,500 organisations by compromising tech-management software from a company called Kaseya has set off a race among criminals looking for similar vulnerabilities, cyber security experts said. An affiliate of a top Russian-speaking ransomware gang known as REvil used two gaping flaws in software from Florida-based Kaseya to break into about 50 managed services providers (MSPs) that used its products, investigators said. Now that criminals see how powerful MSP attacks can be, "they are already busy, they have already moved on and we don’t know where," said head of the non-profit Dutch Institute for Vulnerability Disclosure, which warned Kaseya of the weaknesses before the attack.

‘It’s Quite Feasible To Start A War’: Just How Dangerous Are Ransomware Hackers?

Secretive gangs are hacking the computers of governments, firms, even hospitals, and demanding huge sums. But if we pay these ransoms, are we creating a ticking time bomb? They have the sort of names that only teenage boys or aspiring Bond villains would dream up (REvil, Grief, Wizard Spider, Ragnar), they base themselves in countries that do not cooperate with international law enforcement and they don’t care whether they attack a hospital or a multinational corporation. Ransomware gangs are suddenly everywhere, seemingly unstoppable – and very successful.

Joint UK/US Advisory Detailing Top 30 Vulnerabilities Include Plenty Of Usual Suspects

A joint advisory from law enforcement agencies in the US, UK, and Australia this week tallied the 30 most-frequently exploited vulnerabilities. Perhaps not surprisingly, the list includes a preponderance of flaws that were disclosed years ago; everything on the list has a patch available for whoever wants to install it. But as we've written about time and again, many companies are slow to push updates through for all kinds of reasons, whether it's a matter of resources, know-how, or an unwillingness to accommodate the downtime often necessary for a software refresh. Given how many of these vulnerabilities can cause remote code execution—you don't want this—hopefully they'll start to make patching more of a priority.

Average Total Cost Of A Data Breach Increased By Nearly 10% Year Over Year

Based on in-depth analysis of real-world data breaches experienced by over 500 organisations, the global study suggests that security incidents became more costly and harder to contain due to drastic operational shifts during the pandemic, with costs rising 10% compared to the prior year. Businesses were forced to quickly adapt their technology approaches last year, with many companies encouraging or requiring employees to work from home, and 60% of organisations moving further into cloud-based activities during the pandemic. The new findings suggest that security may have lagged behind these rapid IT changes, hindering organizations’ ability to respond to data breaches.

65% Of All DDoS Attacks Target US And UK

Distributed denial of service (DDoS) attacks are common for cyber criminals who want to disrupt online-dependent businesses. According to the data analysed by a VPN team, 65% of all distributed denial of service (DDoS) attacks are directed at the US or UK. Computers and the internet industry are the favourite among cyber criminals. The United States was a target for 35% of all DDoS attacks in June 2021. Cyber criminals launched DDoS attacks against Amazon Web Services, Google, and other prominent US-based companies in the past. The United Kingdom comes second as it fell victim to 29% of all DDoS attacks. As the UK has many huge businesses, they often are targeted by hackers for valuable data or even a ransom. China was threatened by 18% of all DDoS attacks in June 2021. Assaults from and to China happen primarily due to political reasons, to interrupt some government agency.

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.
