Detects the execution of a binary from the Linux shared memory directory /dev/shm.
This directory is a tmpfs mount backed entirely by RAM and is abused by attackers for fileless malware staging because files written there never touch physical disk and may evade disk-based detection.

Detects the usage of wmic.exe to modify Windows registry via the WMI StdRegProv class write methods (CreateKey, DeleteKey, SetStringValue, etc.).
This behaviour could be potentially suspicious because it uses an alternative method to modify registry keys instead of legitimate registry tools like reg.exe or regedit.exe.
Attackers specifically choose this technique to evade detection and bypass security monitoring focused on traditional registry modification commands.
