Ignore Process Interrupts

Linux · macOS · Windowsnothing on this site yetT1564.011 on attack.mitre.org

Adversaries may evade defensive mechanisms by executing commands that hide from process interrupt signals. Many operating systems use signals to deliver messages to control process behavior. Command interpreters often include specific commands/flags that ignore errors and other hangups, such as when the user of the active session logs off.

how MITRE says to see it

Detection Strategy for Ignore Process Interrupts

Execution of processes using nohup or shell redirection to ignore SIGHUP and continue running after session termination. Defender perspective: correlation between commands including nohup, disowned jobs, or `&` suffix with continued process execution after parent terminal exit.
PowerShell or script execution with parameters that suppress errors or ignore user interrupts, such as `-ErrorAction SilentlyContinue`. Defender perspective: detecting discrepancies between suppressed error arguments and continued execution behavior.
Use of nohup, disown, or AppleScript constructs to suppress process interrupts. Defender perspective: commands containing nohup or hidden background tasks (`osascript` with persistent execution) correlated with processes surviving user logouts.
