Extreme Threat
IP 37.148.132.172 is a critical-risk address operating from Brazilian network infrastructure (AS210356 / BattleHost) that has generated 161 abuse reports within a two-month window, with automated honeypot sensors flagging it exclusively for general hacking activity including unauthorized access attempts and anomalous TCP stream behavior.
The aggregate confidence score of 82 percent across 20 identical automated honeypot detections establishes a consistent threat profile for this IP during March and April 2026. The detection sources recorded Suricata alerts indicating that the hostile traffic involved RST and FIN packets sent with no corresponding active session, along with spurious retransmissions — patterns that are characteristic of port scanning, session enumeration, or connection testing against exposed services. Despite a stated activity frequency of 0/10, the 161 total reports and critical 10/10 threat classification confirm this address represents an active, persistent actor in the threat landscape.
The dominant "Hacking" classification encompasses intrusion attempts, vulnerability probing, and unauthorized access vectors that exploit unpatched or misconfigured services. The Suricata stream anomalies observed are consistent with reconnaissance activity — the attacker mapping open ports and services before attempting exploitation — or could indicate attempts to manipulate TCP session state to bypass authentication or firewall rules. Any exposed service listening on this IP's targeted infrastructure faces a concrete risk of credential stuffing, brute-force attempts, or exploitation of known vulnerabilities.
Site operators should immediately block or rate-limit traffic from 37.148.132.172 at the network perimeter firewall, implement geo-based restrictions if Brazilian source traffic is not expected, and audit exposed services for unnecessary open ports or authentication bypass vectors. Deploying or strengthening fail2ban rules on SSH, RDP, and web login endpoints will automate hostile IP blocking based on failed-authentication thresholds. Maintaining comprehensive logging and alerting for the observed Suricata signatures will enable rapid identification of follow-on activity from this or neighboring addresses within AS210356.
