MYRA RAT LD_PRELOAD Persistence via node.exe Dropping .libcache.so

Detects evidence of the MYRA RAT attempting to establish persistence via the LD_PRELOAD environment variable. This is achieved by creating or modifying malicious shared libraries (e.g., .libcache.so) and configuring system startup files (e.g., /etc/profile.d/.sh.local) to ensure the library is loaded by the dynamic linker on startup.
