Substantial Risk
IP 3.131.215.38 is a high-risk address assessed at 8/10 threat level that has accumulated 15,106 abuse reports, with automated honeypot sensors flagging it primarily as an exploited host actively engaged in malware and exploit activity against exposed services.
The address belongs to Amazon's global cloud infrastructure (AS16509, AMAZON-02) in the United States and was first reported in August 2025 with continued reporting through December 2025. Despite the exceptionally high volume of total reports, the current activity frequency registers at 0/10, suggesting the aggressive scanning phase may have subsided or shifted patterns. The 61% confidence score indicates moderate certainty in the classification, reflecting that while the exploited-host classification is well-supported by 20 recent reports from honeypot sensors, some ambiguity remains in the full scope of malicious behaviour.
The exploited-host designation means this IP address does not represent a threat actor's own infrastructure but rather a compromised server being weaponised without the owner's knowledge. The reported malware and exploit activity indicates the system is likely running malicious scripts or participating in automated attack campaigns, such as scanning for vulnerabilities, launching exploits against web applications, or propagating further compromise. Because the legitimate operator is unaware of the misuse, this IP poses an ongoing risk to any exposed services it targets, particularly those accessible from the internet with unpatched software or weak authentication.
Site operators should block this IP address at the firewall or web application layer as an immediate precaution. Implementing automated blocking tools such as fail2ban or equivalent intrusion-prevention systems can detect and deny repeated connection attempts in real time. Organizations running internet-facing services should ensure all software is patched, enforce strong authentication, and monitor logs for scanning activity originating from this address. Operators who identify sustained targeting are encouraged to report the activity to Amazon's abuse team, as notifying the hosting provider may help remediate the compromised system and disrupt the attack chain.
