Severe Risk
IP 77.90.185.18 is a German IP address operated by Inside Network LTD (AS215476) that presents a critical threat level of 10/10, according to automated honeypot sensors that logged 1,441 abuse reports between January and April 2026. The dominant threat category recorded against this address is general hacking activity, including exploitation attempts and unauthorized access vectors. Despite a low current activity frequency score, the sheer volume of historical reports establishes this as a high-risk address that should be treated with suspicion on any exposed network perimeter.
The detection data for IP 77.90.185.18 reveals sustained malicious behavior over a four-month window, with automated honeypot sensors documenting repeated intrusion-oriented activity. The reported threat categories consistently center on hacking, with a confidence score of 65% indicating moderate certainty in the classification. Network traces associated with this address show TCP stream anomalies, specifically packets with broken acknowledgment flags, a pattern commonly observed during reconnaissance sweeps and vulnerability probing. The volume of 1,441 reports against this single address within a compressed timeframe strongly suggests automated scanning or sustained campaign activity rather than isolated probe attempts.
Hacking activity of this nature represents an immediate risk to any exposed service, particularly those accessible from the internet without robust authentication controls. The broken acknowledgment packets detected are consistent with techniques used to fingerprint operating systems, evade detection, or establish stateful connections for subsequent exploitation. An address with this report density has almost certainly been used to scan for vulnerable services, attempt credential-based attacks, or probe for unpatched software. Organizations exposing SSH, RDP, web interfaces, or database services to this IP range face elevated risk of compromise if preventive measures are not in place.
Site operators should implement immediate blocking or rate-limiting for IP 77.90.185.18 at the firewall or intrusion prevention level. Enforcing strong authentication mechanisms—including key-based authentication for SSH and multi-factor authentication for remote access services—substantially reduces the effectiveness of any ongoing credential attacks. Deploying tools such as fail2ban or similar dynamic blocklist utilities can automatically mitigate repeated connection attempts. Additionally, maintaining current intrusion detection signatures and monitoring for the TCP stream anomalies described will help identify any attempts to bypass filters. Regular patch management and network segmentation further limit exposure should this or any similar address successfully breach perimeter defenses.
