Elevated Risk
IP 83.142.209.41, registered in Ukraine and operated by Demenin B.V, is classified as a high-risk address with a threat level of 7 out of 10, primarily linked to email spam distribution and web application reconnaissance activity. The IP has accumulated 1,348 total abuse reports across automated honeypot sensors, making it one of the more frequently reported addresses within recent tracking windows, though its current activity frequency is assessed as minimal at 0 out of 10.
Detection data shows this address was first reported in November 2025 and most recently in April 2026, indicating sustained abuse across approximately five months of observation. The concentration of reports spans 20 distinct automated honeypot sensors, suggesting broad automated detection coverage rather than isolated flagging. Email spam constitutes the dominant threat category with 19 documented instances, while web application probing accounts for a single reported event. Despite the high report volume, the low activity frequency score indicates that the IP may be currently dormant or operating below detection thresholds, which is typical of abuse infrastructure that has been partially blocked or is cycling through targets.
Email spam activity from this address poses concrete risks to organizational infrastructure, as mass unsolicited messages frequently serve as delivery mechanisms for phishing campaigns and malware payloads. The web application probe detected against this IP suggests automated vulnerability scanning behavior, likely attempting to identify exposed services, misconfigured endpoints, or OWASP Top 10 weaknesses such as injection points and file inclusion vectors. The discrepancy between the high total report count and low current activity frequency may indicate that this IP was previously active at scale before receiving broad blocks, though it remains a verifiable threat vector based on historical evidence.
Site operators should implement email authentication protocols including SPF, DKIM, and DMARC to reject unauthorized sending from this address and similar sources. Deploying a web application firewall with rulesets targeting automated scanning patterns will mitigate probing attempts. Rate-limiting incoming connections and implementing fail2ban or equivalent dynamic blocking tools on exposed services provides an additional hardening layer. Continuous monitoring of abuse feeds and blocking repeat offenders from thisASN range remains advisable given the volume and duration of reported activity.
