Summary:
A novel cryptojacking attack campaign called Commando Cat exploits exposed Docker remote API servers to deploy cryptocurrency miners using Docker images from the open-source Commando project. Malicious actors use the cmd.cat/chattr image to gain initial access, employing techniques like chroot and volume binding to access the host system. Recommendations for mitigating such attacks include proper configuration of containers and APIs, using trusted Docker images, and following container security best practices.
Based on the meeting notes, the key takeaways are:
1. A cryptojacking attack campaign called Commando Cat exploits exposed Docker remote API servers to deploy cryptocurrency miners using Docker images from the open-source Commando project, specifically the cmd.cat/chattr image.
2. Malicious actors use cmd.cat/chattr to gain initial access, employing techniques like chroot and volume binding to break out of the container and access the host system.
3. Attack indicators include specific User-Agent strings and the use of DropBear SSH on TCP port 3022, which can help detect the presence of the malware.
4. To mitigate similar attacks, it is essential to adhere to container security best practices, properly configure containers and APIs, and use trusted Docker images.
Potential actions to address these takeaways include implementing security best practices for containers and APIs, such as minimizing exploitable attack surfaces, using official or certified images, running containers with restricted privileges, and conducting regular security audits.
Additionally, security solutions are recommended for safeguarding Docker servers, such as Trend Vision One™ for automated container image and registry scanning and Trend Cloud One™ – Workload Security for protecting workloads against unknown threats.
Threat hunting can also be supported through potentially useful queries in Trend Vision One. Furthermore, the noted MITRE ATT&CK techniques and associated indicators of compromise should be highlighted for further security measures.
