The Rise of Akira Ransomware

The Akira ransomware group has racked up more than $244 million through its operations, signaling a significant threat to enterprises worldwide. Emerging in early 2023, Akira has specifically honed its ransomware to target VMware ESXi servers. Their reach spans critical infrastructure across North America, Europe, and Australia.

A notable attack in June 2025 saw Akira encrypt sensitive virtual machine files on Nutanix servers by exploiting a vulnerability in SonicWall firewalls. This highlights their proficiency in navigating complex systems and exploiting known vulnerabilities like CVE-2020-3580 and CVE-2023-28252.

Akira’s tactics are highly sophisticated. They include using stolen credentials to compromise SonicWall devices, employing brute force on VPN endpoints, and deploying remote access tools. They’ve also been known to bypass file protections through clever maneuvers like copying domain controller data. Victims often see their data exfiltrated within hours, followed by a swift encryption process.
