Notable Threat
IP 3.151.241.153 is a high-risk address operating from Amazon's AWS infrastructure (AS16509, AMAZON-02) that has generated 441 abuse reports at a threat level of 8/10, indicating sustained malicious activity over a four-month window between February and May 2026. With a confidence score of 94% and activity frequency rated 8/10, this IP presents a concrete and ongoing threat to exposed network services. The dominant threat profile combines general hacking intrusions, web application probing, and evidence of potential exploited-host behavior, suggesting the address may be performing multi-vector attacks against target systems at scale. Community and automated honeypot sensors have logged over 400 distinct incident reports, making this one of the more actively detected hostile addresses in recent operational data.
Detection across 20 separate honeypot sensors captured varied attack patterns including protocol mismatch anomalies, web application probes, and malware-related activity. The primary threat category—Hacking, representing 19 of the most recent reports—encompasses unauthorized access attempts and exploitation of vulnerable services, while Web App Attack (3 recent reports) indicates deliberate targeting of application-layer weaknesses. The geographic location in the United States and association with a major cloud provider does not imply legitimate use, as compromised cloud instances are frequently leveraged as attack platforms due to their reputation for reliability and broad network access.
Web application attacks targeting this IP have included probing for application-layer vulnerabilities and exploitation patterns consistent with OWASP Top 10 categories. The detected protocol mismatch events suggest the address is testing network configurations or attempting to bypass detection by sending malformed traffic. Combined with the high volume of reports, this activity indicates systematic, automated reconnaissance and exploitation efforts rather than manual probing. Organizations running exposed web services, SSH endpoints, or other network-facing applications should treat any connection attempt from this IP as hostile until proven otherwise.
Site operators should block IP 3.151.241.153 at the network perimeter or firewall level immediately. Deploying fail2ban or equivalent dynamic blocking tools can automate this process for continued protection. All exposed services should enforce strong authentication, apply security patches promptly, and be monitored for unusual access patterns. A web application firewall provides an additional layer of defense against application-layer probing. Given the Exploited Host classification in recent reports, considering notification to the hosting provider about potential compromise aligns with responsible security practices.
