Threat intelligence analysis has linked 13.250.145.97 to malicious activity originating from Singapore, Singapore, operating on the network of Amazon.com, Inc.. The address has been under observation since its initial detection. Over a period of 86 days, this IP generated 2,534 malicious requests, averaging approximately 29.5 requests per day. The diversity of 3 separate attack methods suggests a comprehensive attack toolkit — likely an automated scanner that tests for vulnerabilities across multiple categories. Singapore currently accounts for 101 blocked IPs in our database, making it a significant source of malicious traffic. The score of 70/100 indicates a confirmed malicious actor. Network-level blocking is appropriate.
Distributed denial of service attacks overwhelm infrastructure with traffic volume. Effective mitigation combines always-on traffic scrubbing, anycast network distribution, rate limiting, and the ability to quickly scale absorption capacity during attacks.
Digital forensics preserves and analyzes electronic evidence following attacks. Proper chain of custody, forensic imaging, timeline reconstruction, and artifact analysis are essential for understanding attack scope, attribution, and preventing recurrence.
