Extreme Threat
IP 37.60.141.158 is a high-risk address operating from Bulgaria (AS213438, ColocaTel Inc.) with a critical threat level of 10/10, supported by 581 total abuse reports filed through automated honeypot sensors over a concentrated two-month window from September to October 2025. The dominant threat profile centers on general hacking activity and web application attacks, accounting for 20 categorized reports, with the remaining volume attributed to undifferentiated probe activity detected across the sensor network.
The report volume of 581 events over a 60-day period represents sustained hostile activity, with detection sourced from 20 distinct automated honeypot installations that captured both web application probe patterns and generic intrusion attempts. The 62% confidence score reflects the nature of the data—automated detection of suspicious behavior rather than confirmed successful compromises. Geographic attribution to Bulgaria and network ownership by ColocaTel Inc. provides context for the IP's origin, though threat actors frequently utilize bulletproof hosting providers and compromised infrastructure, meaning the stated operator does not necessarily imply direct malicious intent by the ASN holder.
Hacking activity in this context refers to unauthorized access attempts, vulnerability exploitation, and intrusion probing against exposed services, while web application attacks specifically target application-layer weaknesses such as those enumerated in OWASP Top 10 classifications. The combined 20 categorized reports indicate that automated honeypot sensors identified this address attempting to exploit web-facing applications and potentially compromise systems through standard intrusion methodologies. The concrete risk involves unauthorized data access, service disruption, or establishing persistent access to vulnerable infrastructure.
Site operators should implement immediate blocking or rate-limiting for this address and similar Bulgarian ranges exhibiting comparable behavior, particularly on SSH, RDP, and web application ports. Deploying fail2ban or equivalent log analysis tools to automatically ban repeat offenders provides an additional layer of automated defense. Organizations running web applications should ensure all software is patched and consider deploying a web application firewall to filter common attack patterns. Continuous monitoring of authentication logs for source IPs matching this address will help identify any successful connection attempts that may require credential rotation or incident response procedures.
