North Korean Lazarus Group Now Working With Medusa Ransomware

North Korean state-backed attackers are utilizing Medusa ransomware in their ongoing extortion attacks against the U.S. healthcare sector. The Symantec and Carbon Black Threat Hunter Team discovered evidence of North Korean actors employing Medusa in an attack on a Middle Eastern target and an unsuccessful attempt on a U.S. healthcare organization. Medusa, launched in 2023, operates as a ransomware-as-a-service. The Lazarus sub-group Stonefly has been a key player in North Korean ransomware attacks, using proceeds to fund espionage activities. Despite indictments and rewards, the attacks continue unabated. The current campaign employs various tools, including Comebacker, Blindingcan, ChromeStealer, and RP_Proxy. While the attacks bear similarities to previous Stonefly operations, the exact sub-group responsible remains unclear.

Mủ cao su nguyên chất là màu trắng, nhưng lốp xe lại nhuộm màu đen vì nhà sản xuất pha “carbon black” vào cao su. Thành phần này tăng độ bền, giảm mài mòn, cải thiện khả năng tỏa nhiệt và chống tia UV, nên lốp xe xanh hơn, bền hơn và an toàn hơn. 🚗🖤 #Rubber #Tire #Science #CaoSu #LopXe #CôngNghệ #Physics #ĐộBền #UV #CarbonBlack
