Maximum Danger
IP 85.11.167.11 is a critical-risk address originating from Bulgaria that has been linked to sustained brute-force attacks, with a threat level of 10/10 and over 2,000 abuse reports filed through automated honeypot sensors since December 2025. The address, operated under AS213438 by ColocaTel Inc., has demonstrated an activity frequency of 8/10, indicating near-continuous malicious engagement against exposed database services, with recent reports dominated by PostgreSQL authentication probing and general intrusion attempts.
The threat assessment for 85.11.167.11 is grounded in substantial empirical data: 2,026 total reports submitted by 20 independent automated honeypot sensors yield a confidence score of 92%, placing this address among the most consistently reported sources of database-oriented credential attacks in the observed timeframe. The detected attack patterns include systematic PostgreSQL brute-force activity and generic attack connection attempts, suggesting the host is engaged in credential stuffing campaigns targeting misconfigured or internet-exposed database servers. The sustained seven-month reporting window from December 2025 through July 2026 indicates persistent, organized scanning behavior rather than opportunistic or transient activity.
Brute-force attacks against database authentication systems represent a serious threat to any organization running PostgreSQL or similar services on internet-facing infrastructure. Attackers systematically cycle through credential combinations, exploiting weak or default passwords to gain unauthorized database access. Successful authentication grants adversaries direct access to sensitive data stores, application backends, and potentially lateral movement opportunities within the network. The automated nature of these attacks enables mass scanning across millions of IP addresses, making any exposed database authentication endpoint a likely target.
Organizations running PostgreSQL or comparable database services should immediately audit authentication configurations and restrict access to trusted IP ranges wherever feasible. Deploying rate-limiting mechanisms and account lockout policies substantially raises the computational cost of brute-force campaigns. Enforcing strong, unique passwords across all database accounts and enabling multi-factor authentication mechanisms provides critical defense-in-depth. Monitoring authentication logs for the originating IP and similar sources, potentially with tools such as fail2ban, enables rapid automated response to ongoing brute-force activity.
