Hello and welcome to our weekly cybersecurity news wrap up.
We begin with the big story of the week, Twitter's former CSO filing a whistleblower testimony against his former employer. Peiter Zatko claims that Twitter misled users and U.S. federal regulators about glaring weaknesses in its ability to protect personal data. Zatko also claims that Twitter underestimated the number of automated bots on its platform - - billionaire Elon Musk's argument for withdrawing from his bid for the company. A statement to Agence France-Presse on Tuesday from a Twitter spokesperson said, "What we've seen so far is a false narrative about Twitter and our privacy and data security practices that is riddled with inconsistencies and inaccuracies and lacks important context," adding, "Security and privacy have long been company-wide priorities at Twitter and will continue to be."
Widely used password manager LastPass just announced a security incident involving an unauthorized party gaining access to its internal network. Fortunately 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 did take portions of 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. Surgeries also had to be postponed. The attackers are reportedly demanding a $10 million ransom. According to Safety Detectives, security experts believe it is likely CHSF was hit by a strain of the Ragnar Locker ransomware, the same ransomware strain that targeted DESFA, one of Greece’s major natural gas operators. That attack also occurred last weekend. Following the incident, DESFA deactivated most of its IT services and then slowly brought services back online. As of several days ago, the company was refusing to negotiate with the cybercriminals responsible for the attack.
Major airline technology provider Accelya confirmed on Tuesday it is a victim of a ransomware attack. Data from the company, which provides services to some of the world's top airlines, has been posted on a ransomware leak site. The perpetrator is the AlphV/Black Cat ransomware group, which claims it has stolen emails, employee contracts and more. The hacking group is allegedly connected with recent incidents at a major energy supplier in Luxembourg and German fuel company OilTanking GmbH. According to Security Affairs, Blackcat ransomware is one of the fastest fastest-growing Ransomware-as-a-Service (RaaS) underground groups practicing so called “quadruple extortion” by pressing 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 has been described as a major ransomware attack. It resulted in data theft and the damage “beyond repair” of some core systems. Stoke-on-Trent-based Holdcroft Motor Group was hit with a ransom demand after hackers stole two years’ worth of data including staff information. The attack occurred on July 28th. While most systems are now back up and running, some of the company's core systems have been permanently deleted.
That's a wrap. Have a great weekend!

ZDNet (August 24, 2022) Peiter 'Mudge' Zatko: CSO-turned-whistleblower says Twitter security was in a shambles
The former chief of security at Twitter has filed a whistleblower testimony that its physical and digital security systems for protecting user privacy and moderating content suffered extreme deficiencies.
Peiter 'Mudge' Zatko was hired as Twitter's chief security officer by company co-founder Jack Dorsey in November 2020, but was terminated in January 2022 by current CEO Parag Agrawal, who assumed that role after Dorsey stepped down in November 2021.

Bleeping Computer (August 23, 2022) French hospital hit by $10M ransomware attack, sends patients elsewhere
The Center Hospitalier Sud Francilien (CHSF), a 1000-bed hospital located 28km from the center of Paris, suffered a cyberattack on Sunday, which has resulted in the medical center referring patients to other establishments and postponing appointments for surgeries.
CHSF serves an area of 600,000 inhabitants, so any disruption in its operations can endanger the health, and even lives, of people in a medical emergency.
"This attack on the computer network makes the hospital's business software, the storage systems (in particular medical imaging), and the information system relating to patient admissions inaccessible for the time being," explains CHSF's announcement (translated).
