Extreme Threat
IP 204.76.203.213 is a critical-risk address originating from the Netherlands that has been linked to automated web application attacks and brute-force login attempts against content-management platforms. With 463 abuse reports filed across a two-month window between September and October 2025, this IP presents a sustained and dangerous threat to publicly accessible web services, earning a perfect 10/10 threat score despite a moderate 67% confidence rating.
The activity was detected exclusively through automated honeypot sensors, which logged the IP across 20 distinct detection points over a compressed reporting window. The dominant threat category is web application attacks, representing the majority of recent reports, followed by general hacking activity and targeted brute-force probes against WordPress login and administrative interfaces. Attack-pattern telemetry from sensors confirms Drupal reconnaissance signatures alongside broad web application probing behaviour, indicating an automated infrastructure scanning for known vulnerabilities and misconfigurations in web-facing systems. The network is operated by Pfcloud UG under ASN AS51396, and the high report density relative to the detection span suggests this is a deliberate, systematic campaign rather than opportunistic scanning noise.
Web application attacks exploit vulnerabilities in internet-facing software, including those tracked in the OWASP Top 10, and can lead to data breaches, site defacement or remote code execution depending on the exposed flaw. When combined with brute-force activity targeting WordPress admin panels, an attacker can chain initial reconnaissance with credential-guessing to gain authenticated access to a target site. The detection of Drupal-specific probes reinforces that the actor behind this IP actively enumerates popular CMS platforms for known vulnerabilities, making any unpatched web application a direct target.
Operators exposing web services to this IP range should immediately block or rate-limit the address at the firewall or load-balancer level. Deploying a web application firewall will catch and neutralise probing requests before they reach application logic. Ensuring all CMS installations, plugins and server software are fully patched eliminates the vulnerabilities these automated scans are designed to find. Implementing fail2ban or equivalent log-analysis tools on authentication endpoints can automatically ban repeated login failures from this source. Continuous monitoring of access logs for requests originating from this IP, particularly Drupal-related path probes and WordPress admin page requests, will provide early warning if the activity resumes.
