What it detects

This rule detects execution of Advanced Port Scanner, a dual-use network discovery tool frequently abused by ransomware operators to map internal hosts and services before lateral movement. It was observed in RMM-driven intrusions culminating in Akira ransomware. Presence of this tool on servers or endpoints often indicates hands-on-keyboard reconnaissance.
