Critical Threat
IP 206.123.145.76 is a high-risk address associated with sustained unauthorized access attempts, scoring a maximum threat level of 10/10 with 784 independent abuse reports submitted through automated honeypot sensors over a concentrated two-month window in early 2026.
The address, registered to Netface Limited under autonomous system AS60223 in the United States, has generated a substantial volume of incident reports since its first appearance in March 2026, with continued activity through April 2026. All 20 of the most recent threat reports classify the observed behavior exclusively under the hacking category, indicating a persistent focus on intrusion and exploitation rather than opportunistic scanning. Network detection systems flagged a Suricata alert corresponding to an active SSH session detected on an expected port, suggesting the address has been observed attempting to establish or maintain persistent remote access to target systems. Despite the elevated report count, the activity frequency metric registers at zero out of ten, which may reflect either recent dormancy following enforcement actions or limitations in the frequency sampling methodology used by reporting sensors.
The hacking classification encompasses a broad spectrum of intrusion activity including vulnerability exploitation, credential attacks, and unauthorized access attempts against exposed services. When an attacker successfully identifies an accessible SSH daemon, even on a standard port, they gain a direct pathway to authenticate against a system's most privileged accounts. The confirmed presence of an active SSH session detected by honeypot infrastructure indicates this address has progressed beyond mere scanning into active engagement with target systems, elevating the risk from theoretical to concrete.
Site operators running publicly accessible SSH services should treat any inbound connection from this address as malicious by default. Implementing fail2ban or equivalent dynamic blocking tools that automatically add repeat offenders to firewall deny-lists provides an effective first line of defense. Enforcing key-based authentication exclusively, disabling password authentication entirely, and restricting SSH access to known administrative IP ranges will substantially reduce the attack surface. Continuous monitoring of authentication logs for source IP 206.123.145.76 combined with automated alerting ensures rapid detection of any follow-up attempts to circumvent initial blocks.
