  • Checks hardware identifiers (DMI) 1 TTPs 4 IoCs

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

  • Enumerates running processes

    Discovers information about currently running processes on the system

  • Legitimate hosting services abused for malware hosting/C2 1 TTPs 3 IoCs
  • 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 45 IoCs
  • Enumerates kernel/hardware configuration 1 TTPs 24 IoCs

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

  • Reads runtime system information 64 IoCs

    Reads data from /proc virtual filesystem.

  • Writes file to tmp directory 2 IoCs

    Malware often drops required files in the /tmp directory.
