We saw a bit of ransomware drama this week, mostly centered around LockBit, who saw their data leak sites taken down by a DDoS attack after they started leaking the allegedly stolen Entrust data.
Last week, LockBit claimed responsibility for a ransomware attack on cybersecurity giant Entrust and began leaking the company’s allegedly stolen data Friday evening.
Soon after leaking the data, LockBit’s Tor data leak sites experienced a DDoS attack that made them inaccessible.
Researchers released reports this week on a Genshin Impact anti-cheat driver being abused to terminate antivirus processes during ransomware attacks and a new extortion group called Donut Leaks.
Finally, this week’s ransomware attacks include DESFA, Center Hospitalier Sud Francilien (CHSF), Instituto Agrario Dominicano, and Bombardier Recreational Products (BRP).
