What it detects

This rule detects execution of an lsa.exe tool with debug and module switches writing to a debug.bin file, the credential-dumping utility used in Operation GhostShell. Attackers run this to extract secrets from LSASS-related material and stage them for exfiltration. The specific command-line switches and output filename make this a distinctive credential-theft indicator.
