Gentlemen ransomware uses multiple EDR killers to disable defenses

The Gentlemen ransomware gang has been actively developing and maintaining a suite of endpoint detection and response (EDR) killers to help affiliates evade detection in attacks. The gang employs a collection of EDR-killing tools, most notably a utility dubbed GentleKiller, which has at least eight variants impersonating various legitimate security products.

What Happened

• The Gentlemen ransomware gang has been using EDR killers to disable defenses in attacks.
• Novo Nordisk suffered a data breach due to a leaked GitHub token, highlighting the risk of software development pipeline vulnerabilities.
• Nintendo of America confirmed that threat actors stole survey data from a third-party service used internally.
• A critical bug in FIFA's World Cup streams was exposed, allowing for potential remote takeover.

Why It Matters

The recent incidents demonstrate the evolving threat landscape and the need for organizations to prioritize cybersecurity. The use of EDR killers by the Gentlemen ransomware gang highlights the importance of robust defenses, while the data breaches at Novo Nordisk and Nintendo emphasize the need for secure software development pipelines.
