High Risk
45.144.212.240 is a high-risk IP address with a threat level of 8/10, linked to SSH brute-force attempts and SMTP spam activity. Operating from Kprohost LLC's AS214940 network infrastructure in Ukraine, this address has accumulated 645 total abuse reports with an activity frequency rating of 8/10, indicating persistent and aggressive malicious behavior across multiple targeting vectors.
Automated honeypot sensors across 20 distinct detection points confirmed activity spanning October 2025 through January 2026, with 12 reports specifically documenting SSH intrusion attempts and 8 reports tied to email spam abuse. The detection confidence stands at 77%, and defensive systems have already responded by blocking SSH access attempts via fail2ban. The sustained volume of reports over this three-month window demonstrates this is not opportunistic scanning but rather a deliberate, repeated campaign targeting exposed services across multiple victims simultaneously.
SSH brute-force attacks represent a direct pathway to server compromise through systematic credential guessing. Successful authentication grants attackers persistent command-level access, enabling data exfiltration, cryptocurrency mining deployment, or use of the compromised host as a pivot point for lateral network movement. The concurrent SMTP spam activity suggests possible participation in coordinated botnet operations or phishing distribution networks, amplifying the threat beyond a single targeting vector. Each failed authentication attempt signals an active adversary continuing to probe for misconfigured or weakly secured SSH daemons.
Site operators should immediately block 45.144.212.240 at the firewall level and implement key-based authentication for SSH access while disabling password-based login entirely. Changing the default SSH port reduces automated scanning exposure, and deploying tools such as fail2ban with aggressive ban thresholds provides automated response to repeated authentication failures. Enabling two-factor authentication, monitoring authentication logs for patterns originating from this address range, and integrating IP blocklists into mail gateway filtering collectively reduce both attack surfaces this threat actor has demonstrated willingness to exploit.
