This rule monitors for the potential memory dump of the init process (PID 1) through gdb. Attackers may leverage memory
|
|
dumping techniques to attempt secret extraction from privileged processes. Tools that display this behavior include
|
|
"truffleproc" and "bash-memory-dump". This behavior should not happen by default, and should be investigated thoroughly.
