What it detects

This rule detects RAR being used to archive collected files into the hardcoded C\ProgramData\NetWorks\ZZ staging directory. This behavior was observed in attacks against industrial organizations that deploy data-upload implants and archive victim data before exfiltration. Catching the local staging stage exposes collection before data leaves the network.
