Maximum Danger
IP address 176.65.149.45 represents a critical threat with a maximum threat level of 10/10, based on 213 total abuse reports and a 91% confidence score indicating highly reliable attribution to malicious activity. This Netherlands-based address has been consistently flagged for hacking activity, including intrusion attempts and unauthorized access operations, with automated honeypot sensors recording the bulk of detections across the first half of 2026.
The IP resides within AS51396 operated by Pfcloud UG (haftungsbeschrankt), a Netherlands network provider, and has generated a notably high volume of reports relative to typical malicious actors. All 20 of the most recent threat reports classify the activity as hacking, and detection originated exclusively from automated honeypot sensors, suggesting sustained, automated scanning or exploitation campaigns rather than isolated manual attempts. The activity frequency rating of 8/10 confirms persistent engagement with target systems over approximately six months, from January through June 2026.
Hacking activity encompasses a broad spectrum of intrusion tradecraft, including vulnerability probing, brute-force authentication attacks, and exploitation of unpatched services. The sustained nature of this IP's engagement with honeypot infrastructure indicates an actor systematically cataloguing internet-exposed systems for compromise. Organizations with SSH, RDP, web applications, or other network services directly accessible to the internet face the highest risk, as these represent the most likely targets of such systematic reconnaissance and exploitation attempts.
Site operators should immediately block 176.65.149.45 at the firewall level and implement automated blocking via tools such as fail2ban to handle repeated attempts dynamically. Enforcing strong, unique credentials combined with multi-factor authentication dramatically reduces the effectiveness of credential-based intrusion. Keeping all systems patched and running intrusion detection monitoring provides defense-in-depth against the exploitation techniques this actor employs. Regular review of access logs for connections originating from this address and similar Netherlands netblocks will help identify any successful compromise attempts.
