Malware Config

Signatures

  • Checks hardware identifiers (DMI) 1 TTPs 1 IoCs

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

  • Reads hardware information 1 TTPs 1 IoCs

    Accesses system info like serial numbers, manufacturer names etc.

  • Changes its process name 64 IoCs
  • Checks CPU configuration 1 TTPs 1 IoCs

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

  • Reads CPU attributes 1 TTPs 9 IoCs
  • Enumerates kernel/hardware configuration 1 TTPs 41 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.
