Severe Risk
IP 204.76.203.219 is a critical-risk address operated by Pfcloud UG in the Netherlands that has accumulated 513 abuse reports from automated honeypot sensors between September 2025 and January 2026, with web application attacks dominating its recent threat profile and indicators that the host itself may be compromised and weaponized.
The sustained activity window spanning approximately five months across 20 distinct honeypot sensors reflects persistent hostile reconnaissance rather than opportunistic scanning bursts. The 10/10 threat level combined with a 79% confidence score indicates strong correlation between observed behavior and known malicious patterns, while the AS51396 network registration with Pfcloud UG places this IP within a hosting environment rather than consumer infrastructure. Detection signatures reveal both automated exploitation toolkit activity and structured web application probing patterns consistent with vulnerability scanners.
Web application attacks represent the dominant threat category, encompassing exploitation attempts against common web vulnerabilities including those listed in OWASP Top 10 classifications. The secondary exploited host classification suggests this address may simultaneously function as a compromised attack platform being leveraged by threat actors without the system owner's awareness. This dual role elevates risk exposure for any organization with web-facing services, as the IP presents both an active threat to external targets and potential command-and-control infrastructure characteristics.
Blocking or significantly restricting inbound access from this IP address at the network perimeter is strongly recommended given its maximum threat classification. Deploying web application firewalls, maintaining rigorous patch management cycles, and implementing strict authentication controls on all exposed services will substantially reduce vulnerability to the observed attack patterns. Organizations should consider utilizing automated defensive tools such as fail2ban to dynamically block repeated connection attempts matching known malicious signatures. Additionally, community reporting mechanisms should be consulted to monitor for any shifts in this IP's threat behavior or emerging attack campaigns.
