PowerShell LNK Byte Extraction
This rule detects PowerShell processes executing commands that involve reading bytes from a .lnk file. This behavior is often associated with malware attempting to extract malicious content embedded within a shortcut file, potentially for further execution or to bypass security controls. The rule specifically looks for `powershell.exe` or `pwsh.exe` in the image filename or original filename, combined with command-line arguments containing both `.lnk` and `readallbytes`.
