Extreme Threat
IP 37.148.133.221 is a maximum-threat-level address that has generated 197 abuse reports within a concentrated two-month window, indicating sustained and systematic hacking activity rather than opportunistic scanning. With a threat score of 10 out of 10 and a 79 percent confidence rating, this Brazilian IP represents a clear danger to any exposed network service it targets.
Automated honeypot sensors logged all 197 reports for IP 37.148.133.221 between March and April 2026, with every classified incident falling under the hacking threat category. The IP operates within AS210356, managed by BattleHost, and the report volume relative to the short detection window (roughly three report events per day) suggests the address is assigned to an active automated attack platform rather than a compromised end-user device. The zero activity-frequency rating indicates that while the IP generates consistent reports, the individual connection attempts are spaced apart, a pattern typical of distributed attack tools cycling through large IP pools to evade simple rate-based blocking.
The hacking classification assigned to IP 37.148.133.221 encompasses broad unauthorized-access activity, including vulnerability exploitation attempts, credential probing, and intrusion-enumeration techniques designed to identify weaknesses in exposed services. Each "attack connection" represents a potential entry vector if the target system lacks proper hardening, updated patching, or strong authentication controls. The real-world risk is that even a single successful connection against an unpatched or misconfigured service could grant an attacker persistent access to sensitive data or complete system control.
Site operators should block or heavily rate-limit traffic from IP 37.148.133.221 at the firewall or load-balancer level. Implementing automated dynamic blocking using tools such as fail2ban in combination with strict authentication policies — including certificate-based authentication where feasible and mandatory multi-factor enforcement for administrative interfaces — will significantly reduce exposure. Regular vulnerability scanning and prompt patching of exposed services eliminate the specific weaknesses such hacking activity targets. Continuous monitoring of authentication logs for repeated failure patterns originating from this address will provide early warning if the IP attempts to circumvent initial blocks.
