Sub-technique of: T1497
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.
Platforms: Linux, macOS, Windows
The following tests are from Atomic Red Team and provide actionable ways to test this technique:
Uses the ping command to introduce a delay before executing a malicious payload.
Supported Platforms: linux, macos
ping -c #{ping_count} 8.8.8.8 > /dev/null
#{evil_command}
If Atomic Red Team tests are not applicable, manually verify the technique by:
Identify Attack Surface: Determine if the target environment is susceptible to Time Based Checks by examining the target platforms (Linux, macOS, Windows).
Assess Existing Defenses: Review whether mitigations for T1497.003 are in place. If defenses are absent or misconfigured, this technique may be exploitable.
Execute Test: Use tools and methods described in the MITRE ATT&CK page and external references below.
No specific mitigations documented for this technique.
