Evolution of Akira Ransomware Gang
Since its emergence in March 2023, the Akira ransomware gang has conducted a staggering 250 attacks, accumulating approximately $42 million in ransom payments. The rapid success and significant earnings of the gang indicate a high level of expertise and adaptability in their tactics.
Initially focusing on Windows systems, the gang has now expanded its operations by deploying a Linux variant targeting VMware ESXi virtual machines.
