XMRig is a widely used open-source software designed for mining Monero (XMR), a privacy-focused cryptocurrency. While it serves legitimate purposes for cryptocurrency enthusiasts and miners, XMRig is frequently exploited by cybercriminals who secretly install it on victims' computers to mine Monero without consent - a practice known as cryptojacking. This unauthorized mining can significantly slow down affected devices and increase electricity usage, making XMRig a common tool in cyberattacks targeting both individuals and organizations.
