Maximum Danger
IP 45.135.194.48 is a maximum-threat-level address originating from Germany that has accumulated 240 abuse reports from automated honeypot sensors, signalling sustained malicious activity focused on IoT exploitation and unauthorized access attempts against networked devices between January and April 2026.
The IP operates within AS51396 owned by Pfcloud UG (haftungsbeschrankt) and has been flagged across 20 separate automated honeypot sensors, with the report distribution spanning four months. The dominant threat categories are hacking activity, accounting for 11 recent reports, and IoT-targeted attacks representing 9 recent reports. Despite a low activity frequency score of 0/10, the sheer volume of reports combined with a 70% confidence rating and the maximum threat classification indicates this address poses a significant and credible danger to any exposed service.
The IoT-targeted activity is particularly concerning because Internet of Things devices commonly run outdated firmware, retain default credentials and lack proper security hardening, making them ideal targets for compromise and recruitment into botnets or pivoting points for deeper network intrusion. The concurrent hacking category suggests this address is also conducting general intrusion attempts beyond IoT-specific probes, indicating a broad attack methodology targeting multiple vulnerability classes across exposed systems.
Site operators should immediately block 45.135.194.48 at the firewall level, implement rate-limiting on authentication endpoints using tools such as fail2ban, segregate IoT devices onto isolated network segments away from critical infrastructure, and enforce strong unique credentials alongside regular firmware updates on all connected devices to reduce exposure to this threat profile.
