Critical Threat
IP 50.212.116.145 is a high-risk address associated with SSH brute-force attacks, generating 1,598 reports from automated honeypot sensors across a two-month window in early 2026. Assigned to Comcast Cable Communications under ASN AS7922 in the United States, this residential IP has been flagged with a maximum threat score of 10 out of 10, reflecting a sustained and aggressive campaign targeting Secure Shell services.
Analysis of the reported threat categories shows an even split between general hacking attempts and SSH-specific activity, with 19 reports attributed to each classification. Suricata sensor alerts explicitly document recurring SSH brute-force attempts and established sessions on expected SSH ports, confirming systematic credential-guessing behaviour. The detection footprint spans 20 independent honeypot sources, indicating broad probing across multiple infrastructure points. Although current activity frequency is assessed at zero out of ten, the sheer volume of historical reports demonstrates a persistent automated threat that operators should not dismiss.
SSH brute-force activity represents a direct path to server compromise. Attackers systematically iterate through username and password combinations to gain unauthorized shell access; a single successful guess can yield full administrative control over a target host. Compromised servers frequently become platforms for data exfiltration, lateral network movement, cryptocurrency mining or botnet recruitment. The volume of 1,598 reports from this single IP reflects an automated, high-frequency operation rather than casual scanning, meaning any exposed SSH service within range faced repeated, targeted attempts during the reporting window.
Operators maintaining publicly accessible SSH services should implement key-based authentication exclusively, eliminating password-based logins that are vulnerable to guessing. Moving the SSH daemon to a non-standard port reduces exposure to automated scanners that target port 22 by default. Deploying fail2ban or equivalent intrusion-prevention tools to dynamically block IPs after repeated failed attempts provides an automated defensive layer. Disabling root login, enforcing strong passphrase policies, and implementing connection rate-limiting at the network perimeter further harden exposure. Continuous monitoring of authentication logs for unusual patterns remains essential for early detection of any successful intrusion despite these precautions.
