Critical Threat
IP 176.65.139.11 is a high-risk German address with a maximum threat score of 10/10 that has generated 201 abuse reports from automated honeypot sensors since February 2026, indicating sustained and aggressive intrusion activity.
The address belongs to AS51396, operated by Pfcloud UG (haftungsbeschrankt), and was first flagged in February 2026 with continued activity logged through May 2026. All 201 reports cite general hacking activity, including unauthorized access attempts and vulnerability exploitation patterns. The 94% confidence score reflects strong agreement across detection sources, while the 8/10 activity frequency demonstrates persistent engagement against target systems over a four-month period.
Hacking activity represents one of the most dangerous threat categories an exposed service can face. This classification encompasses a wide spectrum of intrusion techniques, from automated vulnerability scanning to targeted exploitation attempts. The volume and persistence of reports suggest this address is part of an active automated attack infrastructure, capable of systematically probing networks for entry points and exploiting known vulnerabilities in unpatched systems.
Blocking this address at the network perimeter is strongly recommended, along with implementing strict rate-limiting on authentication endpoints to slow brute-force attempts. Deploying defensive tools such as fail2ban or comparable intrusion prevention systems can automatically detect and respond to suspicious connection patterns. All exposed services should be kept current with security patches, and operators should enforce strong, unique credentials alongside multi-factor authentication where possible to limit the impact of any successful intrusion attempt.
