Cybersecurity researchers have revealed coordinated cloud-based scanning activities that targeted 75 unique “exposure points” earlier this month. Observed by GreyNoise on May 8, 2025, this activity involved up to 251 malicious IP addresses geolocated in Japan and hosted by Amazon. The threat intelligence firm reported that these IPs exhibited 75 distinct behaviors, including CVE exploits, misconfiguration probes, and reconnaissance activities. Notably, the IPs remained inactive before and after this surge, suggesting they were temporarily rented for a single operation. The scanning efforts targeted various technologies, including Adobe ColdFusion, Apache Struts, Apache Tomcat, Drupal, Elasticsearch, and Oracle WebLogic. This opportunistic operation included attempts to exploit known CVEs and probes for misconfigurations, highlighting the threat actors’ intent to identify weaknesses in web infrastructure.
