What it detects

This rule detects extraction of the password-protected ClickFix archive at.7z with 7-Zip, which unpacks the NetSupport RAT binary neservice.exe onto the host. Adversaries leverage password-protected archives to smuggle the RAT past content inspection, making extraction of this campaign-specific archive a useful post-delivery indicator.
