Notable Threat
IP 77.83.39.131, allocated to Ukrainian hosting provider Kprohost LLC under autonomous system AS214940, presents a moderate-to-elevated threat profile with a 7/10 threat level and a total of 1,040 abuse reports sourced from 20 automated honeypot sensors. The dominant threat classification is Email Spam, accounting for the vast majority of recent reports, supplemented by a single Hacking-category report. Despite the high cumulative report count, the activity frequency metric of 0/10 indicates that the most recent observed hostile behavior has subsided relative to peak periods. The IP was first flagged in January 2026 and most recently reported through March 2026, establishing a multi-month threat window.
The report corpus reveals a heavily email-focused abuse pattern: 19 of the 20 categorized reports cite Email Spam, while only 1 report attributes Hacking activity. Network-level inspection additionally surfaced a Suricata alert referencing a broken acknowledgement in a TCP stream, a pattern consistent with anomalous SMTP session handling that is characteristic of mass-mailing botnets or misconfigured spam-sending infrastructure. The honeypot sensor network detected these behaviors across multiple unrelated deployments, lending moderate credibility to the aggregate signal at a 60% confidence score. The geographic attribution to Ukraine and the AS214940 network context further situate this activity within a commercial hosting environment where threat actors frequently provision short-lived abusive assets.
Email spam is not a victimless nuisance; mass-distribution campaigns serve as delivery vehicles for credential-phishing lures, business email compromise payloads, and malware-dropping attachments that directly endanger end users and corporate networks. The broken-ack Suricata alert additionally signals that whatever process drove the SMTP abuse engaged in non-standard TCP behaviour, which can indicate either compromised end-hosts running covert relay scripts or deliberately evasive sending techniques designed to bypass basic connection-rate thresholds. Even a single hacking-category report suggests that the same infrastructure was simultaneously used for intrusion-adjacent probing, expanding the IP's risk surface beyond purely reputational harm.
