Hyenae-Ng - An Advanced Cross-Platform Network Packet Generator And The Successor Of Hyenae

#473
Topic created · 1 Posts · 0 Views

  • Hyenae NG (Next Generation) is a re-write of the original Hyenae tool which
    was originally published back in the year 2010.
    Besides switching from C to C++, using modern design concepts, Hyenae NG was
    (just like the original Hyenae) written with maximum portability in mind.
    Since the original Hyenae had a very complex command line syntax Hyenae NG
    comes with a fast and intuitively usable command line menu that will allow
    you to effectively set up even complex stress-tests or attack scenarios
    within seconds.

      Project Goals
      The original Hyenae project started out as a study of network stack
      implementations but then quickly gained more complex features such as a
      remote daemon and an attack asistent. Even if it was widely accepted and is
      still a very commonly used tool in todays pen-testing workflows it has a
      complex command line syntax and requires some training and research in order
      to be used properly.
      With Hyenae NG i would like to provide the complexity and felxibility of
      Hyenae in a clean and easy to use command line tool which can be instantly
      used without any futher research on the command line arguments to pass for
      the specific scenarios.

      Improvement ideas and bug reports are very welcomed.
      Basic Usage
      Once you start Hyenae NG, it will enter the main menu state. From here you can
      set up your desired output, generator and dispatcher configuration.
    • Output Setup
      The output setup let you choose from several different output option. You
      can either have Hyenae NG's output ignore by selecting "No Output" our you
      can have it send to either a file or a network adapter. Once you have
      selected an output, you can enter it's sub setup by selecting it again by
      either entering it's menu item number again or by simply pressing enter.
      Outputs that have a sub-setup are marked with a (...) once they are
      selected.
    • Generator Setup
      The generator setup let you chose from several different generators. Most
      generators provide a payload option for which you can select another
      generator and so on. Since network frame generators are nested in transport
      layers, their available payload generators will differ based on the
      previously chosen frame generator. Here is an example of a typical
      payload nesting for an ethernet packet:
    Ethernet +-> ARP  
    |  
    +

    IPv4 +-> ICMPv4

    ICMP Echo Payload | +-> TCP | +-> UDP | +-> ... | +

    IPv6 +-> ICMPv4

    ICMP Echo Payload +

    ICMPv6

    ICMP Echo Payload +-> TCP +-> UPD +-> ...
    • Dispatcher Setup
      The dispatcher setup will let you set up the actual data dispatcher. You
      can define stop-limits or configure a fixed or random send delay in order
      to break flood detection mechanisms on your target system.
      IMPORTANT
      It is reccomended to use a fixed send delay of at least 100 ms on low
      spec systems such as the GPD Pocket 2 in order to prevent key-press
      detection issues.
    • Start Dispatcher
      Once you have set a generator, you can choose this option to start up the
      dispatcher and start sending packets. If you haven't set a generator yet,
      an error message will be shown instead. The dispatcher will operate until
      either a stop-limit (if set) is reached or the user presses any key. After
      the dispatcher has stopped you can either return to the main menu by
      entering 0 or start it again by either entering 1 or simply pressing enter.
      Generator Patterns
      A lot of packet generator parameters such as for address-, port- and number-
      fields can be providing with a generator pattern. These patterns will be used
      in order to generate a new value on every new packet. Here are some examples
      of a few basic patterns:
    • Random 5-digit number:
      *****
    • Incremental 3-digit number:
      +++
    • Decremental 2-digit number:
      --
    • Random number between 100 and 190:
      1*0
    • Incremental number from 1 to 991:
      ++1
    • Decremental number from 299 to 200:
      2--
    • Random IPv4 address between .200 and .255:
      129.168.0.2**
    • Incremental MAC address between :00 and :FF:
      AA:BB:CC:DD:EE:++
    • Decremental IPv6 address between :FFFF and :FF00:
      1000:2000:3000:4000:5000:6000:7000:FF--
      Configuration File
      When Hyenae NG is started it will look for a configuration file named
      "hyenae.conf" in it's startup folder. If the file does not exist it will
      automatically create it.
      IMPORTANT
      If the configuration file can not be parsed, Hyenae NG will give out an
      error message, requesting you to either fix or delete the configuration
      file.
    • Frontend Section
    • terminal_colors
      If set to "on" (default), Hyenae will use ANSI terminal colors in order
      to enhance it's user interface. If for some reasons the terminal you
      are using does not support ANSI colors, you should set this to "off".
    • line_chars
      If set to "on" (default) hyenae will use special line characters for
      it's menu separators (In ASCII on Windows and UniCode on *nix based
      systems). If you are encountering any strange separator outputs, you
      should set this to "off".
