Linux Magic SysRq Key Abuse
Detects potential abuse of the Linux Magic SysRq (System Request) key by adversaries with root or sufficient privileges to manipulate or destabilize a system. Writing to /proc/sysrq-trigger can crash the system, kill processes, or bypass standard logging. Monitoring SysRq abuse helps detect stealthy post-exploitation activity. Correlate with related EXECVE or PROCTITLE events to identify the process or user responsible for the access or modification.
