Elevated Risk
IP 2.57.122.89 is a high-risk address originating from Romania, operated by Unmanaged Ltd under ASN AS47890, that has been reliably linked to sustained SSH brute-force attacks with a threat level of 8/10 and a confidence score of 83 percent. The IP generated 289 total abuse reports across 20 distinct automated honeypot sensors between December 2025 and June 2026, indicating persistent, high-volume malicious activity that operated continuously over a seven-month period with an activity frequency rated 8/10.
Detection data reveals that the overwhelming majority of hostile activity from 2.57.122.89 consists of automated SSH brute-force attempts, with additional hacking and general brute-force activity accounting for a smaller portion of the 289 reports. The honeypot sensor logs document repeated violation events in the sshd jail, with some entries showing 25 repeated violations, and notably the recidive jail triggered multiple times, confirming that this source was previously blocked and subsequently returned to resume attacks. The volume and pattern of these automated detection events across twenty separate sensor sources strongly indicate a coordinated, scripted campaign rather than isolated manual probing.
SSH brute-force attacks systematically attempt to guess server credentials by iterating through common username and password combinations, exploiting systems that retain weak or default authentication settings. When successful, such intrusions grant attackers persistent remote access to servers, enabling data exfiltration, malware deployment, botnet recruitment, or lateral movement within networks. The recidive classification for IP 2.57.122.89 signals that this source persisted despite prior countermeasures, demonstrating determined intent and automated retry capability that heightens the risk to any exposed SSH service.
Network defenders should immediately block 2.57.122.89 at the firewall or network perimeter level and monitor for future reappearance. Exposed SSH services should enforce key-based authentication exclusively, disable root login, and consider relocating the SSH daemon to a non-standard port. Implementing rate limiting and account lockout policies substantially raises the cost of brute-force campaigns, while deploying tools such as fail2ban can automatically ban repeat offenders. All SSH servers should receive prompt patch management to mitigate any vulnerabilities that might aid authentication bypass attempts.
