Numerous NPM users and packages have been observed by Checkmarx researchers to be automatically created recently, with all of the packages found to have nearly the same code as the Eazyminer package for Monero mining.
While downloading the packages would not adversely impact machines, CuteBoi altered the configuration files of Eazyminer to specify the recipient server of mined cryptocurrency.
"At the heart of these packages are the XMRig miners. Their binaries, compiled for Windows and Linux systems, are shipped along with the packages. The attacker changes the names of these binaries to match the random names of the package themselves," wrote researchers.
