Severe Risk
IP 37.148.132.208 is a critical-risk address linked to 303 accumulated abuse reports and associated with sustained hacking activity detected by automated honeypot sensors. Operating from Brazil under network operator BattleHost (ASN AS210356), this IP has earned a maximum threat rating of 10 out of 10, reflecting a consistent pattern of intrusion-oriented behavior over its reporting window in April 2026.
The confidence score of 79 percent across 303 total reports indicates reliable, corroborated evidence of malicious activity rather than isolated noise. Twenty recent reports specifically categorize the activity as Hacking, with detection attributed entirely to automated honeypot infrastructure monitoring exposed services. The attack signatures include SURICATA STREAM spurious retransmission alerts, which flag anomalous TCP behavior where packets are transmitted without legitimate connection context. This pattern is characteristic of reconnaissance operations, port scanning, or sophisticated evasion techniques designed to probe network defenses without establishing proper handshake protocols.
Spurious TCP retransmissions represent a concrete threat vector beyond generic brute-force attempts. Attackers use malformed or orphaned packets to test firewall reaction rules, identify filtering weaknesses, or fingerprint operating systems before launching targeted exploits. The presence of an explicit "attack connection" notation alongside stream anomalies suggests active exploitation attempts rather than passive scanning, elevating the risk profile for any exposed service listening on this IP's targeted ports.
Network defenders should treat 37.148.132.208 as hostile and implement immediate blocking at the perimeter firewall or intrusion prevention system. Enforcing strict TCP stateful inspection will reject packets lacking valid three-way handshake context, neutralizing retransmission-based probing. Deploying tools such as fail2ban or equivalent connection-rate monitoring can automate dynamic blocking based on anomalous behavior thresholds. Regular review of honeypot telemetry feeds and maintenance of up-to-date blocklists aligned with community abuse reports will further reduce exposure to this and similar threat actors.
