Coordinated Scanning Activity Targeting ColdFusion, Struts, and Elasticsearch Uncovered
May 28, 2025 | Network Security / Vulnerability
Recent investigations by cybersecurity experts revealed a coordinated scanning initiative that exploited vulnerabilities across a range of platforms. On May 8, 2025, GreyNoise observed suspicious activity from approximately 251 malicious IP addresses, all linked to Amazon Web Services and geolocated in Japan. These IPs engaged in 75 varied actions, which included attempts to exploit known vulnerabilities (CVEs), probes for misconfigurations, and reconnaissance efforts targeting web infrastructures.
The targeted technologies encompassed notable frameworks and services, including Adobe ColdFusion, Apache Struts, Apache Tomcat, Drupal, Elasticsearch, and Oracle WebLogic. The nature of these scanning operations indicates that the threat actors were probing for weaknesses, exhibiting a strategic approach aimed at identifying exploitable points in the web architecture of organizations utilizing these technologies. GreyNoise noted that the activity was marked by a distinct silence surrounding these IPs before and after the observed surge, suggesting they were temporarily rented to undertake this specific operation.
In terms of tactics potentially employed in this incident, the MITRE ATT&CK framework offers insight into the methodologies likely at play. Initial access could have been achieved by leveraging known vulnerabilities associated with the targeted technologies. The attack may also reflect persistence tactics, wherein the threat actors sought to establish ongoing access to compromised systems. Moreover, privilege escalation techniques could have been utilized to gain elevated permissions once inside the infrastructure.
The implications of such scanning activities are significant. Threat actors often utilize similar methods to identify and exploit vulnerabilities that can lead to unauthorized access or data breaches, underlining the importance of proactive monitoring and fortification of web applications. Organizations are advised to ensure that they maintain current security patches, conduct regular security audits, and stay vigilant against such scanning activities to bolster their defenses against potential exploitation.
As the cybersecurity landscape continues to evolve, staying informed about emerging threats is crucial for business owners. The findings from this recent episode serve as a reminder that even established technologies can be points of vulnerability if not adequately protected. Awareness and preparedness are essential in mitigating the risks posed by opportunistic attacks like these.
