Maximum Danger
IP 85.11.167.11 is a critically dangerous address associated with sustained automated intrusion activity, ranking at a maximum threat level of 10/10 with over 2,000 independent abuse reports from honeypot sensors spanning approximately eight months of observed malicious behavior originating from Bulgarian infrastructure.
The IP address, registered to ColocaTel Inc. under autonomous system AS213438, generated a substantial volume of 2,027 reports across 20 distinct automated honeypot sensors between December 2025 and July 2026. The activity frequency score of 8/10 indicates near-continuous hostile engagement, while the confidence rating of 91% reflects high certainty in the malicious classification based on consistent detection patterns. The dominant threat categories include general hacking intrusion attempts (18 recent reports) and brute-force authentication attacks (2 recent reports), with sanitized pattern data specifically referencing PostgreSQL database brute-force activity alongside generic attack connections. This concentration of database-focused credential guessing against a backdrop of broad intrusion activity points to an actor systematically probing for weak database authentication across exposed infrastructure.
The dual threat profile presented by this address poses significant real-world risk to any organization running publicly accessible PostgreSQL instances or similar database services without proper access controls. PostgreSQL brute-force campaigns attempt to systematically guess administrative credentials, and successful access grants attackers complete control over stored data, the ability to exfiltrate sensitive information, or leverage the compromised database as a persistent foothold into internal networks. Combined with generalized hacking attempts, this IP demonstrates the automated, opportunistic scanning behavior characteristic of botnets or coordinated attack infrastructure seeking any exploitable target rather than a specific organization.
Organizations should immediately block IP 85.11.167.11 at the network perimeter firewall level and implement fail2ban or equivalent intrusion prevention tools configured to detect and auto-block PostgreSQL authentication failures. Enforcing strong, non-default database passwords alongside multi-factor authentication for administrative access substantially raises the cost of successful brute-force attempts. Rate-limiting authentication endpoints and implementing account lockout policies after repeated failures further disrupt automated attack cycles. Continuous monitoring of authentication logs for source IP 85.11.167.11 remains essential given the sustained, high-volume nature of the observed activity.
