Substantial Risk
IP 45.135.193.3 is a high-risk address operating from the Netherlands that has been linked to credential-based attacks against WordPress installations, with automated honeypot sensors recording 252 abuse reports across a concentrated two-month detection window. The Dutch network is AS51396, operated by Pfcloud UG, and the volume of reports combined with the consistent targeting of WordPress login and administrative interfaces places this IP firmly in the 8/10 threat-level category.
Detection data indicates that honeypot infrastructure flagged this address specifically for WordPress Login Brute Force and WordPress Admin Brute Force activity, with each category contributing equally to the reported incidents. The first reports emerged in November 2025, with activity continuing through December 2025. Notably, the activity frequency metric registers at 0/10, suggesting that while historical reports are significant, the IP may be currently dormant or operating below detection thresholds. The 77% confidence score reflects substantial corroboration across the twenty reporting honeypot sensors without reaching absolute certainty.
WordPress brute-force attacks involve automated credential-stuffing campaigns that systematically attempt common username-password combinations against wp-login.php and wp-admin endpoints. These attacks exploit default or weak administrative credentials to gain unauthorised backend access, potentially enabling malware deployment, data exfiltration or complete server compromise. The Drupal-related detection signature further suggests this actor maintains multi-platform capabilities, adapting techniques observed in compromise attempts against other popular content-management systems.
Site operators running WordPress should enforce strong unique passwords for all administrative accounts and consider implementing two-factor authentication as a primary defence against credential-based intrusions. Deploying tools such as fail2ban to dynamically block repeated login failures can significantly reduce exposure, while restricting wp-admin access to trusted IP ranges via .htaccess or firewall rules adds a meaningful barrier. Continuous monitoring of authentication logs for unusual geographic patterns or burst activity from this address remains advisable given the confirmed threat classification.
