Maximum Danger
IP 167.250.224.25 is a maximum-threat Brazilian address generating 8,244 abuse reports across automated honeypot sensors over approximately seven months, with a dominant pattern of hacking activity and web application probing that warrants immediate blocking at network perimeters.
Operating from autonomous system AS265210 under the operator designation OSCAR M DE CARVALHO - ME, this address was first reported in October 2025 and most recently flagged in May 2026, indicating sustained malicious behavior spanning the majority of the observation window. The threat level registers at the maximum score of 10/10, while the confidence rating of 65% reflects the automated nature of detection rather than human-verified attribution. Twenty distinct honeypot sensors across the community contributed reports, with the majority of recent flags categorizing the activity as hacking intrusion attempts (17 reports) supplemented by web application attack vectors (7 reports). The activity frequency of 1/10 suggests that while the address is persistently present, individual connection events occur intermittently rather than in concentrated bursts, consistent with systematic reconnaissance rather than opportunistic noise.
The Suricata stream alerts detected against this IP — specifically spurious retransmissions and packets with broken acknowledgments — reveal TCP-level manipulation techniques designed to exploit stateful inspection weaknesses or evade detection by fragmenting attack signatures across anomalous network sequences. The web application probe component indicates active scanning for vulnerabilities including file inclusion, injection points, and other OWASP Top 10 exposure categories. Together, these patterns suggest an actor conducting persistent reconnaissance against exposed services, probing for entry points rather than relying on volume-based exploitation.
Network defenders should block this address at the firewall or edge router level immediately, implementing strict inbound filtering based on geographic origin where Brazilian traffic is not business-required. Deploy fail2ban or equivalent connection-rate limiting to throttle repeated probe attempts. Ensure all web-facing applications are current on patches and consider deploying a web application firewall to absorb and log the specific probe patterns observed. Monitor logs for any successful connections from this address to identify potential prior reconnaissance against internal assets.
