Severe Risk
IP 45.173.176.254 is a critical-risk address linked to 572 abuse reports and sustained hacking activity, originating from the Brazilian network AS268818 operated by Kobertura Telecom LTDA, with automated honeypot sensors detecting persistent intrusion attempts during January-February 2026.
The available intelligence shows all 20 recent reported incidents categorized as hacking activity, sourced exclusively from automated honeypot detection systems. While the overall confidence score stands at 64%, the cumulative report volume paints a consistent picture of a threat actor engaged in systematic probing and unauthorized access attempts. The activity timeframe spans from January through February 2026, indicating a concentrated campaign rather than isolated incidents. Geographic attribution to Brazil places this source within a South American network operator, which aligns with patterns observed in automated credential-based attacks targeting internet-facing services globally.
Hacking activity in this context encompasses vulnerability exploitation attempts, intrusion enumeration, and unauthorized access probing against exposed services such as SSH, Telnet, or web interfaces. The volume of 572 reports demonstrates persistent interest from this address in compromising target systems, with each report representing a detected attempt that would have succeeded against unpatched or misconfigured targets. Real-world risk includes credential theft, data exfiltration, and establishment of footholds for subsequent lateral movement within victim networks. The honeypot-derived detections suggest this IP participates in broad scanning campaigns that systematically catalogue and exploit exposed attack surfaces.
Network defenders should immediately block this IP at perimeter firewalls and intrusion prevention systems based on its confirmed malicious reputation. Implementing fail2ban or equivalent authentication hardening tools on SSH and remote access services will automate blocking of repeated connection attempts. Rate-limiting login attempts and enforcing strong, unique credentials alongside multi-factor authentication significantly reduces the effectiveness of the intrusion techniques employed. Regular security patching and monitoring of authentication logs for the geographic origin patterns associated with this source address will further strengthen defensive posture.
