Maximum Danger
IP 45.139.104.213 is a critical-risk address originating from Bulgaria (AS399979, AS-493NETWORKING) that has been directly linked to automated hacking activity, with 598 abuse reports submitted through honeypot sensors and community channels during August 2025. This IP presents a severe threat level of 10/10 based on sustained intrusion-oriented behavior, making it a strong candidate for immediate blocking at network perimeters.
The volume of reports filed against 45.139.104.213 is substantial at 598 total submissions, with the overwhelming majority (19 detections) originating from automated honeypot sensors designed to simulate vulnerable services and one additional community report. All confirmed threat categorizations specifically identify hacking activity, with the first and most recent reports both logged within August 2025. While the activity frequency metric registers at 0/10, the historical report concentration demonstrates a clear pattern of automated exploitation attempts targeting exposed infrastructure rather than one-off scanning events. The geographic origin in Bulgaria and the autonomous system assignment provide network-level context for filtering or enhanced monitoring decisions.
The dominant threat category for this IP is general hacking activity, which encompasses unauthorized access attempts, vulnerability exploitation, and intrusion preparation techniques. The detected patterns suggest this address is engaged in systematic reconnaissance and probing of web server configurations, specifically targeting exposed version control metadata that could reveal source code structure or deployment details. Such enumeration attempts often precede more targeted exploitation campaigns, as the information gathered can inform attackers about software versions, directory structures, and potential vulnerabilities in exposed applications.
Network defenders should implement immediate blocking of this IP address at the firewall level based on its confirmed malicious reputation, while also deploying fail2ban or equivalent intrusion prevention tools to automatically neutralize similar scanning patterns. Organizations should ensure no version control system metadata is accessible via web servers, as this represents a standard hardening practice that eliminates the information advantage attackers seek. Maintaining current patch management cycles and deploying web application firewalls will further reduce exposure to the exploitation techniques this address has been observed attempting. Ongoing traffic monitoring and log analysis for the detection signatures associated with this IP will help identify any attempted follow-up activity from adjacent threat infrastructure.
