Virtual Machine Fingerprinting via Grep

• source: elastic
• technicques:
  • T1082

Description

An adversary may attempt to get detailed information about the operating system and hardware. This rule identifies common locations used to discover virtual machine hardware by a non-root user. This technique has been used by the Pupy RAT and other malware.

Detection logic

process where event.type == "start" and
 process.name in ("grep", "egrep") and user.id != "0" and
 process.args : ("parallels*", "vmware*", "virtualbox*") and process.args : "Manufacturer*" and
