The new miner can be a threat to ordinary Linux users, not just servers.
Analysts specializing in cyber security discovered the Japanese company Trend Micro, a crypto-money miner KORKERDS, characterized by some atypical behavior. It is reported on the company's website.
Researchers have not yet determined exactly how the threat has spread. However, most likely, the download takes place after some software has been installed or has a security vulnerability.
The researchers were assigned the Coinminer.Linux.KORKERDS.AB identifier for Mining cryptocurrency miner miner (XMR). It is noteworthy that another component is also used – the rootkit that "hides" the mining process from the monitoring tools (Rootkit.Linux.KORKERDS.AA).
After starting the secret miner's job in the system, the CPU load increases to 100%. However, it is not easy for the user to find out why. The status is complex by readdir and readdir64 APIs and a rootkit that uses the hook for libc library. If the normal library file is overwritten, readdir is replaced with a fake version.
The malicious version of Readdir is used to hide the mining process (kworkerds). After that, despite the fact that the processor load points to suspicious activity, it is much more difficult to define a miner.
According to the researchers, the new miner can be a threat not only to the servers, but also to ordinary Linux users.
