Smash and Grab: Aggressive Akira Campaign Targets SonicWall VPNs, Deploys Ransomware in an Hour or Less
In late July 2025, Arctic Wolf Labs began observing a surge of intrusions involving suspicious SonicWall SSL VPN activity.

Victims spanned across multiple sectors and organization sizes, suggesting opportunistic mass exploitation. This campaign has recently escalated, with new infrastructure linked to it observed as late as September 20, 2025.
