TA0005 · DEFENSE EVASION
Run Virtual Instance
Adversaries may carry out malicious operations using a virtual instance to avoid detection. A wide variety of virtualization technologies exist that allow for the emulation of a computer or computing environment.
Detect it with
Consider monitoring for files and processes associated with running a virtual instance, such as binary files associated with common virtualization technologies (ex: VirtualBox, VMware, QEMU, Hyper-V). Consider monitoring the size of virtual machines running on the system.
Why it matters on shift
Run Virtual Instance is one of the concrete ways adversaries achieve defense evasion. Recognising it in telemetry lets you name the technique in your ticket and pivot to what came before and after.
What to look for next
After defense evasion, the next tactic is usually Credential Access. Search your telemetry for the transition before closing the ticket.
