Significant Threat
IP 3.129.187.38 is a high-risk address operating from Amazon Web Services infrastructure (AS16509, AMAZON-02) in the United States, with a threat level of 8/10 and a confidence score of 90% based on 2,915 total abuse reports and activity detected across 20 automated honeypot sensors over a seven-month window between February and August 2026.
The volume and consistency of reporting make this IP particularly notable. With an activity frequency rated 8/10, the address has generated nearly three thousand incident reports in a relatively compressed timeframe, with the dominant threat category being general hacking activity alongside a smaller number of exploited-host classifications. Detection sensors flagged malware or exploit activity consistent with unauthorized intrusion attempts, including Suricata alerts indicating malformed TLS record types — a technique sometimes employed to evade detection or exploit vulnerable SSL/TLS implementations. The combination of high report volume, diverse attack vectors, and sustained activity intensity strongly suggests this IP is either deliberately conducting scanning and intrusion operations or has been compromised and is being leveraged as an unwitting attack platform by external threat actors.
The detected hacking activity represents a concrete risk to any exposed service accepting connections from this address. Such activity typically encompasses vulnerability probing, exploit delivery attempts, and unauthorized access escalation — patterns that can compromise unpatched systems or misconfigured services within minutes of exposure. The presence of exploited-host classification further indicates that this cloud-hosted address may itself have been compromised and is now being weaponized to launch secondary attacks, effectively laundering malicious traffic through reputable cloud infrastructure and complicating attribution. Organizations with services reachable from this IP face heightened exposure to credential theft, data exfiltration, or malware deployment if proper defensive controls are absent.
Blocking or rate-limiting connections from this IP at the firewall or load-balancer level is the most immediate mitigation step, with tools such as fail2ban capable of automating dynamic blocking based on observed abuse patterns. Enforcing strong authentication — including multi-factor authentication and key-based authentication where applicable — and maintaining a strict patch management cycle will reduce the window of opportunity for successful exploitation. Network defenders should also monitor for the specific Suricata TLS anomaly detected, as malformed SSL/TLS records may indicate early-stage exploit toolkit activity. Finally, organizations receiving connections from Amazon AWS address space should review security group rules and ensure no unnecessary ports or services are exposed to the internet, regardless of the apparent reputation of any single source IP.
