ATT&CK analytic guidance

DET0563 Detection Strategy for Defense Impairment via Prevent Command History Logging across OS platforms.

AN1555 Analytic 1555

Detection of environment variable tampering (HISTFILE, HISTCONTROL, HISTFILESIZE) and absence of expected bash history writes. Correlation of unset or zeroed history variables with active shell sessions is indicative of adversarial evasion.

AN1556 Analytic 1556

Detection of bash/zsh history suppression via HISTFILE/HISTCONTROL manipulation and absence of ~/.bash_history updates. Observing environment variable changes tied to terminal processes is a strong indicator.

AN1557 Analytic 1557

Detection of PowerShell history suppression using Set-PSReadLineOption with SaveNothing or altered HistorySavePath. Correlating these options with PowerShell usage highlights adversarial evasion attempts.

AN1558 Analytic 1558

Detection of unset HISTFILE or modified history variables in ESXi shell sessions. Correlation of suspicious shell sessions with no recorded commands despite active usage.

AN1559 Analytic 1559

Detection of CLI commands that disable history logging such as 'no logging'. Anomalous lack of new commands in session logs while activity persists is a strong signal.

Threat actor context

These are explicit actor-to-technique associations in the existing Threat Matrix snapshot, not attribution of an event or proof that a detector identifies the actor. No tool-to-actor relationship is inferred.
