Malware Config

Signatures

  • File and Directory Permissions Modification 1 TTPs 5 IoCs

    Adversaries may modify file or directory permissions to evade defenses.

  • Executes dropped EXE 5 IoCs
  • Renames itself 1 IoCs
  • Creates a large amount of network flows 1 TTPs

    This may indicate a network scan to discover remotely running services.

  • Enumerates running processes

    Discovers information about currently running processes on the system

  • 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 system routing table 1 TTPs 1 IoCs

    Gets active network interfaces from /proc virtual filesystem.

  • Reads process memory 1 TTPs 64 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
  • Reads system network configuration 1 TTPs 1 IoCs

    Uses contents of /proc filesystem to enumerate network settings.

  • Reads runtime system information 64 IoCs

    Reads data from /proc virtual filesystem.

  • System Network Configuration Discovery 1 TTPs 1 IoCs

    Adversaries may gather information about the network configuration of a system.

  • Writes file to tmp directory 10 IoCs

    Malware often drops required files in the /tmp directory.
