Lastly, the downloaded shell script is executed. Figure 2: How the shell script is downloaded and saved. Once executed, the shell script first checks whether there is an update available for the malware.

If there are no updates available, the shell script will then proceed to its routine by first calling its downloadrun function shown in Figure 4 , which downloads the actual malicious cryptocurrency miner. Although the extension of the URL it connects to is. After downloading and executing the cryptocurrency-mining malware, the shell script then calls its init function, which downloads a version of the initial file. Afterwards , the echocron function is called. The shell script will sleep for 10 seconds then check whether a connection was made on port If there were no connections, it will execute its downloadrunxm function.

It first checks whether there is already a rootkit installed in the affected machine. Typically, process monitoring tools can detect the presence of a cryptocurrency miner. To that end, the rootkit hooks the readdir and readdir64 application programming interfaces APIs of the libc library.

These APIs are commonly used by process monitoring tools to get its information. While the rootkit fails to hide the high CPU usage and the connections made by the cryptocurrency miner, it improved its stealth by just editing a few lines of code and repurposing existing code or tools.

Cryptocurrency-mining malware can cause significant performance issues, especially on Linux systems, given their ubiquity in running and maintaining business processes — from servers, workstations, application development frameworks, and databases to mobile devices.
