Description

Adversaries may employ various time-based methods to detect virtualization and analysis environments, particularly those that attempt to manipulate time mechanisms to simulate longer elapses of time. This may include enumerating time-based properties, such as uptime or the system clock.

Adversaries may use calls like GetTickCount and GetSystemTimeAsFileTime to discover if they are operating within a virtual machine or sandbox, or may be able to identify a sandbox accelerating time by sampling and calculating the expected value for an environment’s timestamp before and after execution of a sleep function.(Citation: ISACA Malware Tricks)

How GTK Cyber trains on this

GTK Cyber's hands-on training programs cover detection engineering across the MITRE ATT&CK framework, including the stealth, Discovery tactic this technique falls under. Our practitioner-led courses focus on building real detections, not just memorizing technique IDs.
