What it detects

This rule detects execution of Advanced IP Scanner, a dual-use network mapping tool frequently staged by ransomware crews to enumerate reachable hosts before lateral movement. The Gentlemen ransomware operators run it during the discovery phase of their intrusions. Detecting it in unexpected contexts can reveal pre-encryption reconnaissance.
