New malware targets Apache Tomcat servers, hijacking resources through stealthy payloads & lateral movement. What to watch for to protect your workloads

Tomcat Vulnerability explore some of the techniques used by the Mirai botnet to exploit a single attack directed at one of our Apache Tomcat honeypots.

Trend Micro Threat Research observed active exploitation of the Spring4Shell vulnerability assigned as CVE-2022-22965, which allows malicious actors to weaponize and execute the Mirai botnet malware. The exploitation allows threat actors to download the Mirai sample to the “/tmp” folder and execute them after permission change using “chmod”.

We began seeing malicious activities at the start of April 2022. We also found the malware file server with other variants of the sample for different CPU architectures.
