MYRA Linux RAT Fileless Execution via memfd_create and fexecve
Detects a fileless execution technique used by the MYRA Linux RAT where a payload is executed from memory using memfd_create and fexecve, effectively bypassing disk-based detection. The rule identifies processes originating from Node.js or npm installation scripts that exhibit anonymous, memory-backed execution paths typical of this malware's lifecycle.
