Summary
A recent campaign targeting Linux systems and turning them into Monero cryptocurrency miners was discovered. The way the malicious payloads spread is either through SSH hijacking or by exploiting misconfigured public-facing Docker instances. Once a machine is infected, the malicious scripts will install an additional program, which will disable security tools and ensure persistence by storing itself as a cron job and launch at system startup. It also removes any other competing malware. The actual malware is a stealthy variant of the XMRig Monero miner.

Minimum set of Manual Rules to improve protection to block this campaign
IMPORTANT: Always follow best practices when you enable new rules and signatures.
When you implement new rules or signatures, always set them to Report mode first and check the alerts generated. Resolve any issues that arise and then set the rules to Block. This step mitigates against triggering false positives and allows you to refine your configuration.
For more information, see KB87843 - List of and best practices for Endpoint Security Dynamic Application Containment rules.
