High Risk

IP 3.137.73.221 is a high-risk address with a threat level of 8/10, linked to persistent hacking activity detected by automated honeypot sensors over approximately six months of reporting. Originating from Amazon's AWS infrastructure (AS16509 / AMAZON-02) in the United States, this IP accumulated 10,228 abuse reports, representing a substantial volume of malicious connection attempts despite its current inactivity status of 0/10.

The evidence base for this assessment comes entirely from 20 automated honeypot sensors that logged connection attempts fitting the hacking category between August 2025 and February 2026. With a confidence score of 63%, the analysis reflects moderate certainty that these reports accurately represent the IP's behavior. The network operator, Amazon Web Services, hosts millions of IP ranges that are frequently repurposed by both legitimate customers and threat actors due to AWS's global scale and reputation for reliable connectivity. The extreme disparity between the 10,228 total reports and the current 0/10 activity frequency suggests this host either successfully achieved its objectives, changed tactics, or was remediated or abandoned by its operators during the reporting window.

Hacking activity encompasses a broad spectrum of intrusion attempts, vulnerability exploitation and unauthorized access probes that automated honeypot sensors flag as suspicious connection behavior. While the abstract attack pattern prevents granular attribution, the sheer volume of reports indicates sustained, systematic scanning or exploitation attempts against exposed services. Even though current activity appears dormant, an IP with this abuse history poses a potential risk if reactivated, as its operators have demonstrated intent to probe target systems. The Amazon AWS origin means traffic from this address may originate through EC2 instances, Lambda functions or other cloud services that can be rapidly provisioned and deprovisioned, complicating long-term reputation tracking.

Site operators should implement defensive measures regardless of this IP's current inactivity status. Deploying fail2ban or similar dynamic blocking tools can automatically ban IPs that trigger honeypot-style connection thresholds. Enforcing strong authentication on all exposed services, particularly SSH and RDP, substantially reduces the effectiveness of the credential guessing and exploitation attempts typical of hacking activity. Regular patching of internet-facing systems eliminates known vulnerabilities that these automated probes often target. Finally, monitoring for renewed connection attempts from this address range and maintaining updated blocklists ensures that any reactivation of this threat can be rapidly identified and neutralized.
