0

Hello and welcome to our weekly roundup of cybersecurity news.

We start with the big story of the week, the former Twitter CSO filing whistleblower testimony against his former employer. Peiter Zatko claims Twitter misled users and US federal regulators about glaring weaknesses in its ability to protect personal data. Zatko also claims that Twitter has underestimated the number of automated bots on its platform – – billionaire Elon Musk’s argument for backing out of its bid on the company. A statement to Agence France-Presse on Tuesday from a Twitter spokesperson said: “What we have seen so far is a false narrative about Twitter and our privacy and data security practices that is riddled with inconsistencies and inaccuracies and lack of important context,” adding, “Security and privacy have long been company-wide priorities at Twitter and will continue to be.”

Widely used password manager LastPass has just announced a security incident involving an unauthorized party accessing its internal network. Fortunately, the users’ master passwords were not compromised. However, LastPass has made it clear that due to its “zero-knowledge” architecture, master passwords are never stored. However, the attackers took portions of the source code and some proprietary technical details. The attackers gained access through a compromised developer account.

Hackers continue to focus their efforts on some of the most important institutions – hospitals and critical infrastructure. In France, the Center Hospitalier Sud Francilien (CHSF) was hit by a ransomware attack on Sunday. The attack on the 1,000-bed hospital forced the medical center to refer patients to other hospitals. Operations also had to be postponed. The attackers are reportedly demanding a ransom of $10 million. According to Safety Detectives, security experts believe it’s likely that CHSF has been hit by a strain of Ragnar Locker ransomware, the same ransomware strain that targeted DESFA, one of the major natural gas operators in Greece. This attack also took place last weekend. Following the incident, DESFA disabled most of its IT services and then slowly brought the services back online. For a few days, the company had refused to negotiate with the cybercriminals responsible for the attack.

Accelya, the airlines’ leading technology provider, confirmed on Tuesday that it was the victim of a ransomware attack. Data from the company, which provides services to some of the world’s largest airlines, was published on a ransomware leak site. The perpetrator is the AlphV/Black Cat ransomware group, which claims to have stolen emails, employee contracts and more. The hacking group is believed to be linked to recent incidents at a major energy supplier in Luxembourg and the German oil company OilTanking GmbH. According to Security Affairs, Blackcat ransomware is one of the fastest growing underground Ransomware-as-a-Service (RaaS) groups, practicing what is called “quadruple extortionby pressuring victims to pay – leveraging encryption, data theft, denial of service (DoS) and harassment.

Also this week, one of the UK’s largest car dealerships was hit by what was described as a major ransomware attack. This has resulted in data theft and “irreparable” damage to some central systems. Stoke-on-Trent-based Holdcroft Motor Group has been the subject of a ransom demand after hackers stole two years of data, including personnel details. The attack took place on July 28. While most systems are now operational again, some of the company’s core systems have been permanently removed.

It’s a wrap. Have a good week-end!
