Severe Risk
IP 2.57.122.177 is a maximum-threat-level address originating from Romania that has generated 12,364 abuse reports over an eight-month period, with automated honeypot sensors identifying it primarily through repeated SSH brute-force attack patterns against exposed authentication endpoints. The IP has earned a perfect 10/10 threat score and an 8/10 activity frequency rating, making it one of the most persistently hostile addresses documented in recent threat-intelligence collections.
Detection data collected between October 2025 and June 2026 shows 20 independent automated honeypot sensors reporting this activity with 86 percent confidence. The dominant threat category is SSH-related intrusion, followed by general hacking attempts and brute-force credential attacks. Suricata intrusion-detection systems flagged repeated sessions on expected SSH ports, while fail2ban blocks confirmed that mitigation systems are actively intervening against this traffic. The IP operates within AS47890 under Unmanaged Ltd, and the sustained high-volume reporting across multiple independent sources paints a clear picture of an address dedicated to systematic authentication attacks.
SSH brute-force attacks systematically cycle through credential combinations to gain unauthorized server access, and the concrete real-world risk is remote code execution or data exfiltration once an account is compromised. The presence of exploited-host classifications in recent reports suggests this address has already been used to successfully breach systems and may now be leveraged for lateral movement or secondary payload delivery. Automated attack tools make this technique scalable, and any exposed SSH service with weak or default credentials faces immediate risk from this type of persistent scanning.
Site operators should block this address at the network perimeter and implement key-based SSH authentication exclusively while disabling password-based logins and root access. Deploying fail2ban to automatically ban repeated authentication failures provides dynamic protection, and rate-limiting incoming SSH connections further reduces exposure. Regular monitoring of authentication logs for unusual patterns and maintaining prompt patch cycles for SSH services closes the window of opportunity for exploitation.
