Severe Risk
IP 2.57.121.148 is a critical-risk address that has generated 25,577 abuse reports linked to hacking activity, including intrusion attempts and exploitation of vulnerable services, detected primarily through automated honeypot sensors operating within Romanian network space. The IP has been actively reported since August 2025 with the most recent activity in October 2025, placing it squarely within the current threat landscape for any organization with internet-facing infrastructure.
The volume of reports alone makes this one of the most prolific hostile addresses in recent threat-intelligence collections. All 20 of the most recent reported threat events map directly to the hacking category, indicating a sustained focus on unauthorized access attempts rather than opportunistic scanning noise. The IP routes through AS47890 (Unmanaged Ltd) in Romania, a network operator frequently associated with limited abuse coordination. While the confidence score sits at 59%, the sheer volume of reports elevates this address to high-priority status for blocking and real-time monitoring regardless of the statistical confidence figure.
Hacking activity encompasses the exploitation of vulnerable services, credential-based attacks, and attempts to compromise systems through known vulnerability chains. The honeypot events detected for this IP suggest automated scanning and exploitation attempts targeting services that may be unpatched or misconfigured. This pattern poses a concrete risk to any organization running SSH, RDP, web applications, or database services without adequate hardening, as successful exploitation can lead to data breach, lateral movement, or ransomware deployment.
Site operators should block this IP at the firewall or edge-device level immediately and implement geo-blocking for Romanian source traffic if business operations do not require it. Authentication hardening—including fail2ban or similar tools, multi-factor authentication, and strict password policies—substantially reduces the success rate of such intrusion attempts. Continuous monitoring of authentication logs and regular vulnerability scanning will help detect any successful compromise attempts originating from hostile addresses like this one.
