Maximum Danger
IP 206.123.145.48 is a critical-risk address associated with active SSH intrusion attempts, having accumulated 782 abuse reports from automated honeypot sensors between March and April 2026. With a threat level scored at 10 out of 10, this US-hosted IP represents a persistent and focused adversary targeting exposed login services.
The IP operates within AS60223 under Netiface Limited and has been flagged across 20 separate honeypot detection points, generating a remarkably high report volume of approximately 39 incidents per sensor on average. Detection sensors specifically flagged SSH session activity on an expected port, indicating the operator is actively probing for weak or default SSH credentials rather than conducting broad reconnaissance. Despite the low activity frequency rating of 0/10, the sheer density of targeted reports within a compressed two-month window demonstrates deliberate, sustained intent rather than opportunistic scanning.
SSH brute-force and credential-stuffing attacks remain one of the most common initial-access vectors in real-world breaches. An attacker who successfully guesses weak administrative credentials on an exposed SSH daemon can gain direct command-line access to a target system, potentially escalating privileges and deploying persistent backdoors or ransomware. The pattern detected here—targeted SSH sessions in progress—suggests automated tooling cycling through authentication attempts in search of a vulnerable entry point. Even organizations with moderate internet-facing footprints are routinely scanned for open SSH ports within hours of going online.
Site operators should immediately block or rate-limit connections from 206.123.145.48 at the network edge and audit SSH access controls across all internet-facing hosts. Enforcing key-based authentication exclusively, disabling root login over SSH, and implementing tools such as fail2ban to automatically block repeated authentication failures will substantially reduce exposure. Continuous monitoring of authentication logs for source IPs matching this range and enforcing least-privilege access principles are essential complementary measures against credential-based intrusion attempts of this nature.
