Signatures

  • Family: Mozi, Mozi Botnet

    Mozi aka MoziBotnet is a multi-platform linux botnet targeting IoT devices.

    botnetmozi
  • Detects Mozi Payload 1 IoCs
  • Contacts a large (10404) amount of remote hosts 1 TTPs

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

    discovery
  • Patched UPX-packed file 1 IoCs

    Sample is packed with UPX but required header fields are zeroed out to prevent unpacking with the default UPX tool.

  • Modifies Watchdog functionality 1 TTPs 2 IoCs

    Malware like Mirai modifies the Watchdog to prevent it restarting an infected system.

    defense_evasion
  • Creates a large amount of network flows 1 TTPs

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

    discovery
  • Enumerates active TCP sockets 1 TTPs 1 IoCs

    Gets active TCP sockets from /proc virtual filesystem.

    discovery
  • 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.

    persistence
  • Reads system routing table 1 TTPs 1 IoCs

    Gets active network interfaces from /proc virtual filesystem.

    discovery
  • Writes file to system bin folder 2 IoCs
  • UPX packed file 1 IoCs

    Detects executables packed with UPX/modified UPX open source packer.

    upx
  • Changes its process name 1 IoCs
  • Reads system network configuration 1 TTPs 3 IoCs

    Uses contents of /proc filesystem to enumerate network settings.

    discovery
  • Reads runtime system information 64 IoCs

    Reads data from /proc virtual filesystem.

    discovery
  • System Network Configuration Discovery 1 TTPs 16 IoCs

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

    discovery
  • Writes file to tmp directory 1 IoCs

    Malware often drops required files in the /tmp directory.
