  • Xorbot

    Xorbot is a linux botnet and trojan targeting IoT devices.

  • Xorbot family
  • Contacts a large (2032) amount of remote hosts 1 TTPs

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

  • Creates a large amount of network flows 1 TTPs

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

  • File and Directory Permissions Modification 1 TTPs 8 IoCs
