Basic server hardening that includes patching, turning off unused services, and limiting external footprints can go a long way toward minimizing the risk of server-based attacks. “Many of the cryptomining samples from Linux-based systems have some relationship to the XMRig application,” explained the report, which showed that 89% of cryptomining attacks used XMRig-related libraries. “Therefore, when XMRig-specific libraries and modules in Linux binaries are identified, it is likely evidence of potential cryptomining behavior.

Some Bitcoin miners https://www.tokenexus.com/what-is-videocoin-vid/ use specialized hardware, and many coin miners join mining pools in which many computers combine their resources and divide the spoils. When coin miners are used without the consent of the device owner, that’s called cryptojacking, and it’s definitely unethical and possibly illegal.
