Extreme Threat
IP address 37.148.132.190 is a maximum-risk address originating from Brazil that has been definitively linked to 311 hacking-related incident reports over a sustained three-month period, with automated honeypot sensors recording persistent malicious activity between March and May 2026. This IP presents a threat level of 10 out of 10 and represents one of the most reliably dangerous sources currently documented in community abuse databases.
The evidence supporting this assessment is robust, with a confidence score of 86 percent across all detection events. All 311 reports uniformly cite hacking activity as the threat category, with the 20 most recent reports originating exclusively from automated honeypot infrastructure. The IP operates within AS210356, allocated to the BattleHost network operator, a provider whose IP space has accumulated significant abuse report volume. The activity frequency rating of 4 out of 10 indicates consistent, recurring behavior rather than opportunistic burst activity, suggesting methodical sustained operations against target infrastructure over the full reporting window.
The dominant threat category—hacking activity—manifests through TCP stream anomalies detected by Suricata intrusion-detection systems. The specific pattern of spurious retransmission detected by sensor alerts indicates abnormal TCP behavior consistent with reconnaissance probing, stateful-inspection evasion attempts, or exploitation of protocol-level vulnerabilities in exposed services. Such activity represents a concrete real-world risk to any service accepting TCP connections from this source, as the underlying techniques are associated with unauthorized access attempts and vulnerability enumeration against targeted systems.
Site operators should immediately block or significantly rate-limit all inbound connections from 37.148.132.190 at the network perimeter. Implementing strict egress filtering and hardening authentication mechanisms on publicly accessible services will reduce exposure to the intrusion techniques this address has demonstrated. Deploying or enhancing Suricata rulesets to detect and alert on anomalous TCP stream patterns provides additional layered defense. Integrating real-time threat-intelligence feeds that consume community abuse data enables automated blocking of repeat-offender IP addresses. Utilities such as fail2ban can proactively ban source addresses generating authentication failure patterns consistent with credential-guessing campaigns.
