Malware Config

Signatures

  • XMRig Miner payload 2 IoCs
  • Xmrig family
  • Xmrig_linux family
  • xmrig

    XMRig is a high performance, open source, cross platform CPU/GPU miner.

  • Checks hardware identifiers (DMI) 1 TTPs 4 IoCs

    Checks DMI information which indicate if the system is a virtual machine.

  • Reads hardware information 1 TTPs 14 IoCs

    Accesses system info like serial numbers, manufacturer names etc.

  • Checks CPU configuration 1 TTPs 1 IoCs

    Checks CPU information which indicate if the system is a virtual machine.

  • Reads CPU attributes 1 TTPs 46 IoCs
  • Enumerates kernel/hardware configuration 1 TTPs 26 IoCs

    Reads contents of /sys virtual filesystem to enumerate system information.

  • Reads runtime system information 10 IoCs

    Reads data from /proc virtual filesystem.

  • Writes file to tmp directory 4 IoCs

    Malware often drops required files in the /tmp directory.
