New Threat in Spotlight

Microsoft updates on ransomware families
Microsoft revealed that it discovered over 35 unique ransomware families and 250 unique threat actors last year. Most of these ransomware leveraged Cobalt Strike and several legitimate enterprise tools ( AnyDesk, Splashtop, and Teamviewer) to gain initial access and persistence on networks. Upon gaining access, most of the attackers create new backdoor user accounts to proceed with the infection chain process. 

Update on COBALT MIRAGE’s attack
Researchers have shared new details about a lesser-known COBALT MIRAGE threat actor group. The gang has been held responsible for launching ransomware attacks across the U.S. The ransomware strains used in the campaign are BitLocker and DiskCryptor.
