Description
The Akira ransomware group has been targeting UK businesses since 2023, primarily affecting retail, finance, manufacturing, and medical sectors. Their tactics include exploiting SSL VPNs, using double extortion, and focusing on financial gain. Key observations from 2023-2025 include initial access through VPN exploitation, discovery tools like Netscan and Advanced Port Scanner, privilege escalation via Veeam vulnerabilities, lateral movement through RDP and SSH, and exfiltration using tools like WinSCP and FileZilla. Akira targets backup systems, encrypts virtual disks and physical devices, and publishes stolen data on a Tor-based website. The group's activities show similarities to the Conti cybercrime organization, indicating possible links between them.
