It’s the Year of the (Clandestine) Linux Desktop!

As if EDR evasions weren’t enough, attackers are now employing yet another method to hide their presence on enterprise systems: deploying tiny Linux VMs. Attackers are using Hyper-V and/or WSL to deploy tiny (120MB disk space and 256MB memory) Linux VMs to host a custom reverse shell and reverse proxy.

In this segment, we’ll discuss strategies and mitigations to battle this novel technique with Rob Allen from Threatlocker.
