ATT&CK analytic guidance
DET0454 Detect Malicious Modification of Pluggable Authentication Modules (PAM)
AN1250 Analytic 1250
Detects unauthorized modifications to PAM configuration files or shared object modules. Correlates file modification events under /etc/pam.d/ or /lib/security/ with unusual authentication activity such as multiple simultaneous logins, off-hours logins, or logons without corresponding physical/VPN access.
AN1251 Analytic 1251
Detects suspicious changes to macOS authorization and PAM plugin files. Correlates file modifications under /etc/pam.d/ or /Library/Security/SecurityAgentPlugins with unexpected authentication attempts or anomalous account usage.
