What it detects

This rule detects curl saving a remote file into the ProgramData Microsoft WindowsDoc directory, matching the CloudZ RAT staging chain that writes update.txt into a fabricated WindowsDoc folder. Downloading a payload directly into a Microsoft-themed ProgramData path masquerades attacker tooling as system content. This ingress behavior indicates active payload retrieval.
