What MITRE ATT&CK T1546.004: Unix Shell Configuration Modification (Enterprise Tactic TA0004 - Privilege Escalation / TA0003 - Persistence) requires
MITRE ATT&CK T1546.004 (Unix Shell Configuration Modification) is an Enterprise Privilege Escalation and Persistence sub-technique of T1546 (Event Triggered Execution). Adversaries may establish persistence through executing malicious commands triggered by a user's shell. User Unix Shells execute several configuration scripts at different points throughout the session based on events. For example, when a user opens a command-line interface or remotely logs in (such as via SSH) a login shell is initiated. The login shell executes scripts from the system (/etc) and the user's home directory (~/) to configure the environment. Affected platforms: Linux, macOS. MITRE-documented mitigations include M1022 Restrict File and Directory Permissions. The Center for Threat-Informed Defense maps this technique to NIST SP 800-53 Rev 5 controls AC-02, AC-03, AC-06, CA-07, CM-02, CM-03, CM-06, IA-09.
