Maximum Danger
IP address 37.148.132.43 is a critical-risk address that automated honeypot sensors flagged 306 times over approximately two months for hacking activity, including intrusion attempts, vulnerability exploitation and unauthorized access probing. The volume of abuse reports and the sustained nature of the detections across honeypot sensors establish a pattern consistent with deliberate hostile reconnaissance rather than accidental misconfiguration.
The address originates from Brazil and terminates within AS210356, operated by BattleHost, a network provider associated with prior abuse activity. Detection occurred exclusively through automated honeypot sensors, which recorded 20 reports citing general hacking activity as the threat category. Suricata alert signatures triggered on the target infrastructure flagged anomalous TCP stream behavior, including spurious retransmissions characteristic of coordinated attack traffic patterns. The first reports emerged in March 2026, with continued activity recorded through April 2026, indicating a sustained engagement window of roughly eight weeks. Despite the high report count, activity frequency registered at zero out of ten, suggesting the hostile traffic was concentrated in short bursts rather than continuous bombardment.
Hacking activity encompasses a broad spectrum of intrusion tradecraft, from automated vulnerability scanning to targeted exploitation of unpatched services and credential-based entry attempts. The observed TCP anomalies point toward infrastructure probing, potentially preceding a data exfiltration attempt, service disruption or lateral movement within a compromised network. The presence of spurious retransmissions often indicates either a stressed target environment or fragmented packet crafting designed to evade detection by security appliances. Each successful probe against an exposed service represents a potential pivot point for an adversary.
Site operators should block or aggressively rate-limit traffic originating from this address at the network perimeter. Exposed services such as SSH, RDP and web administration panels warrant immediate hardening through strong, unique credentials and the enforcement of key-based authentication where feasible. Deploying or configuring defensive tools such as fail2ban can automatically detect and mitigate brute-force patterns. Continuous monitoring of honeypot telemetry and maintain up-to-date threat intelligence feeds will help anticipate follow-on infrastructure used by the same actors.
