IDS: Tor Exit Node
This IP is a known Tor network exit node. Tor anonymizes user traffic by routing it through a series of relays; exit nodes are the final hop where traffic re-enters the public internet. While Tor has legitimate privacy uses, it is heavily abused for anonymous attacks, credential stuffing, and fraud — as the real attacker IP is concealed behind the exit node.
WordPress XML-RPC Abuse
This IP targeted xmlrpc.php, a legacy WordPress endpoint that has been abused for brute-force authentication attacks, credential stuffing, and DDoS amplification. Any direct access to xmlrpc.php is an attack or reconnaissance attempt; modern WordPress sites should disable it entirely.
