Malware Config

Signatures

  • Deletes itself 1 IoCs
  • Runs EXE from memory 1 IoCs

    Runs an executable from memory, likely to minimize footprint

  • Unexpected DNS network traffic destination 5 IoCs

    Network traffic to other servers than the configured DNS servers was detected on the DNS port.

  • Creates/modifies Cron job 1 TTPs 9 IoCs

    Cron allows running tasks on a schedule, and is commonly used for malware persistence.

  • Enumerates running processes

    Discovers information about currently running processes on the system

  • Modifies init.d 2 TTPs 1 IoCs

    Adds/modifies system service, likely for persistence.

  • Reads MAC address of network interface 2 TTPs 1 IoCs

    Fetches the MAC address of active network interfaces. May be used to detect known values for hypervisors.

  • Reads process memory 1 TTPs 50 IoCs

    Read the memory of a process through the /proc virtual filesystem. This can be used to steal credentials.

  • Changes its process name 1 IoCs
  • Enumerates kernel/hardware configuration 1 TTPs 2 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 1 IoCs

    Malware often drops required files in the /tmp directory.
