Significant Threat
31.57.184.107 is a high-risk address operated by Netiface LLC (AS36680, United States) that represents a significant 8/10 threat level, validated at 100% confidence and supported by 199 total abuse reports. This IP has demonstrated concentrated, persistent malicious activity spanning April to June 2026, primarily focusing on WordPress authentication infrastructure through brute-force and user enumeration attack vectors. The activity frequency of 8/10 indicates sustained, aggressive targeting rather than opportunistic scanning.
Detection data from automated honeypot sensors and community reports confirms that 31.57.184.107 has been systematically probing WordPress installations with 5 authentication attempts observed within 5-minute windows against multiple target organizations. The fail2ban system logged 50 violations classified under wordpress-escalation rules, indicating repeated detection and mitigation across different WordPress deployments. Report volume attribution shows 12 honeypot detections and 8 community submissions, demonstrating this threat actor has been active long enough to generate significant cross-source intelligence. The geographic clustering of targets in European regions suggests this IP participates in coordinated scanning campaigns with geographic specificity beyond simple random discovery.
The dominant attack pattern involves WordPress login brute-forcing combined with user enumeration reconnaissance, creating a two-phase credential compromise pipeline. During enumeration, the hostile actor queries WordPress query parameters to harvest valid usernames before deploying automated password-guessing tools against identified accounts. Successful brute-force compromise grants administrative panel access, enabling website defacement, malware injection, data exfiltration, or use of the compromised host as a pivot point for deeper network intrusion. The 5-probe burst pattern observed in honeypot logs indicates sophisticated attack tooling configured to evade basic threshold detection while maintaining aggressive persistence.
Site operators running WordPress deployments should immediately block 31.57.184.107 at the network perimeter firewall or web application firewall level and implement fail2ban rules monitoring authentication endpoints. Enforcing multi-factor authentication on all administrator accounts eliminates credential-based compromise even when passwords are successfully guessed. Rate-limiting login attempts to three or fewer per minute per IP dramatically reduces brute-force viability. Disabling XML-RPC and REST API enumeration endpoints through server configuration or security plugins prevents the reconnaissance phase that enables targeted credential attacks. Continuous monitoring of authentication logs for this IP address pattern remains essential given its demonstrated persistence.
