Maximum Danger
IP 206.123.145.78 is a critical-risk address operated by Netiface Limited (AS60223) under a United States network registration, flagged for sustained SSH hacking activity detected by automated honeypot sensors between March and April 2026. With 785 total abuse reports and a maximum threat score of 10 out of 10, this IP represents a persistent, high-confidence threat to exposed network services.
The 785 reports attributed to 206.123.145.78 were generated exclusively through automated honeypot detection mechanisms, with 20 independent sensor sources confirming the malicious activity within the most recent reporting window. Suricata intrusion-detection signatures specifically identified an SSH session in progress on a standard expected port, indicating that the attacking host was actively attempting to establish an authenticated or semi-authenticated remote-access connection. All 20 recent reports consistently categorised the activity as general hacking, encompassing intrusion attempts, vulnerability exploitation and unauthorized access vectors. Although the attack window spans only approximately two months, the volume of reports relative to the detection period signals concentrated, high-frequency hostile scanning behaviour during the active phase.
SSH brute-force and session-hijacking campaigns against port 22 represent one of the most prevalent initial-access vectors in internet-facing infrastructure attacks. An established SSH session on an expected port, as flagged by the Suricata alert, can indicate either a successful credential-guessing attempt in progress or the use of pre-authenticated tunnelling techniques to pivot deeper into a network. The confidence score of 79% for this IP's threat classification reflects strong evidentiary support from sensor data while acknowledging minor uncertainty inherent in automated detection. Organisations with exposed Secure Shell services face material risk of credential theft, lateral movement and data exfiltration if this IP's activity is not mitigated.
Network operators should immediately block 206.123.145.78 at the firewall or edge-router level and monitor inbound connection logs for any successful authentication events. Implementing fail2ban, ConfigServer Security Firewall or similar dynamic blocking tools can automatically respond to repeated SSH connection attempts from this source. Enforcing key-based authentication exclusively, disabling password authentication for SSH daemons and applying rate-limiting rules to connection attempts will substantially reduce the attack surface. Continuous monitoring of authentication logs for source IP 206.123.145.78 and correlated indicators remains essential even after blocking, as threat actors frequently rotate sources while maintaining consistent targeting patterns.
