1. About Hyenae
Hyenae is a highly flexible and platform independent network packet generator.
It allows you to reproduce low level ethernet attack scenarios (such as MITM,
DoS and DDoS) to reveal potential security vulnerabilities of your network.
Besides smart wildcard-based address randomization, a highly customizable
packet generation control and an interactive attack assistant, Hyenae comes
with a clusterable remote daemon for setting up distributed attack networks.
Hyenae was developed with ease-of-use in mind while still remaining flexible
and configurable. To realize this aim, Hyenae uses address patterns, which
will minimize the number of arguments you have to provide because all
necessary parameters, such as the way you want to randomize your addresses or
the IP address version to use, can be derived from the pattern format you
provided. See section 5, "Address Patterns", for more detailed information.
This utility suite was developed only for network security testing purposes
such as evaluation of firewall rules, flood detection and intrusion detection.
Hyenae's developers disclaim all liability for any direct, indirect or
consequential damages arising out of or connected with the use or misuse of
Hyenae Utility Suite. The user alone assumes all risks and responsibility of
his/her own actions associated with the use of the Hyenae Utility Suite. Every
effort has been made to supply accurate information related to Hyenae. It is
subject to change without prior notice.

-s Source address pattern
-d Destination address pattern. Is also used to define the virtual
IP-Address pattern on HSRP based attacks.
-S Secondary source address pattern. Defines the sender address on ARP-Based
attacks, the requested IP-Address on DHCP-Request attacks and the TCP
source address pattern on TCP based ICMP "Destination Unreachable"
attacks.
-D Secondary destination address pattern. Defines the target address on
ARP-Based attacks, the server identifier (IP-Address) on DHCP-Release
attacks and the TCP destination address pattern on TCP based ICMP
"Destination Unreachable" attacks.
-i Network interface to operate on (specified by name). This argument is
ignored on remote attacks.
-I Network interface to operate on (specified by index). A list
of all available network interfaces and their indexes can be obtained
by starting Hyenae with the -l option. This argument is ignored on remote
attacks.
-r Single remote attack. If set, Hyenae will execute the specified attack
on the Hyenae Daemon specified by the given server address pattern. A
server address pattern has the following pattern format:
// For plain connections
[IP-Address]@[Port]
// For password protected daemons
[IP-Addresss]@[Port]+[Password]
Hyenae will automatically recognize the provided IP address version.
Wildcards are not valid within server address patterns. The password
strip is only required when connecting to a Hyenae Daemon which has
activated password authentication. Note: Since Hyenae currently does not
support encrypted communication, your password is transferred in plain
text, and can be logged by others.
-R Clustered remote attack. If set, Hyenae will simultaneously execute the
specified attack using the Hyenae Daemons specified in the server file at
the given path. A server list file should have the following format:
# Comment
Server=[IP-Address]@[Port]
Server=[IP-Address]@[Port]+[Password]
...
Hyenae will automatically recognize the version of the IP address
provided. Wildcards are not valid within server address patterns. The
password strip is only required when connecting to a Hyenae Daemon which
has activated password authentication. Note: Since Hyenae currently does
not support encrypted communication, your password is transferred in
plain text, and can be logged by others.
-a Attack protocol. A list of all available attacks can be obtained by
starting Hyenae with the -L option.
-A IP address version to assume when a completely random IP strip is found
within an address pattern. This value can be either 4 or 6. By default
this is set to 4 (IPv4).
-t Defines the hop limit (TTL) on IP based attacks. The hop limit can be a
value between 1 and 255. If not set, a hop limit size of 128 will be
used.
-o Defines the ICMP "Destination Unreachable" message code on ICMP
"Destination Unreachable" based attacks, the PPPoE discover code on
PPPoE-Discover based attacks or the HSRP state code on HSRP based
attacks.
Valid values on PPPoE attacks:
padi (Active Discovery Initiation)
padt (Active Discovery Termination)
If not set, the default value is 'padi'.
Valid values on ICMP attacks:
network (Network Unreachable)
host (Host Unreachable)
protocol (Protocol Unreachable)
port (Port Unreachable)
If not set, the default value is 'network'.
Valid values on HSRP attacks:
init
learn
listen
speak
standby
active
If not set, the default value is 'init'.
-f TCP flags. This option is required on TCP attacks and defines the TCP
control flags to set for the generated packets. Valid values are any
combination of:
F (FIN)
S (SYN)
R (RST)
P (PSH)
A (ACK)
-k TCP acknowledgement number. Defines the TCP acknowledgement number to use
on TCP based attacks. If not set or set to 0, an acknowledgement number
of 0 will be used.
-w TCP window size. Defines the TCP window size to use on TCP based attacks.
If not set or set to 0, a window size of 0 will be used.
-q TCP sequence number / PPPoE session id. Defines the TCP sequence number
on TCP based, or the session id on PPPoE-Discover based attacks. If not
set or set to 0 on TCP based attacks, every generated packet (unless a
step value was given) will carry a completely randomized sequence number.
If set to 0 on PPPoE attacks, every generated packet (unless a step value
was given) will carry the session id 0. If a sequence number or session
id incrementation step value was given, this argument will be used as
the initial sequence number or session id to be incremented.
-Q TCP sequence number / PPPoE session id incrementation steps. If set, the
sequence number or session id of every generated packet will be
incremented by the given value.
-y DNS query pattern. A DNS query pattern is required on DNS-Query based
attacks to define the list of domain names to query. The list should have
the following format:
# Single DNS query
[www.domain1.com]
# Multiple DNS queries
[www.domain1.com],[www.domain2.com],...
-h Defines the HSRP authentification data field value and is required on
HSRP based attacks. If not set, the default auth. data will be used
instead. Auth. data values must not be longer than 8 characters.
-z Defines the HSRP priority field value and is required on HSRP based
attacks. This value can be any number betwen 1 up to 255.
-g Defines the HSRP group number on HSRP based attacks. This value can be
any number betwen 0 up to 255. If not set, the group number will be set
to 0.
-c Minimum number of packets to generate. If not set or set to 0, an
unlimited amount of packets will be generated, unless an attack duration
was set. If you provide a maximum number of packets to generate, the
minimum number of packets will be automatically set to one. If not set or
set to 0 on remote attacks, the packet limit of the daemon will be used
instead.
-C Maximum number of packets to generate. If not set or set to 0, the
specified minimum number of packets (-c X) will be generated. If no
minimum number of packets to generate is specified, an unlimited
amount of packets will be generated.
-e Minimum number of milliseconds to wait until the next packet is sent.
On HSRP based attacks the send delay will be used as the hello/hold time
field value and must not be greater than 255000. The hold time on HSRP
based attacks will be hello time multiplied by 3.
-E Maximum number of milliseconds that may pass before the next packet is
sent. If set, Hyenae will wait a random number of milliseconds between
the minimum (-e X or 0 if not set) and the maximum number (-E X) before
sending the next packet. This is useful for breaking flood detections.
On HSRP based attacks the send delay will be used as the hello/hold time
field value and must not be greater than 255000. The hold time on HSRP
based attacks will be hello time multiplied by 3.
-u Minimum attack duration in milliseconds. If not set or set to 0, the
attack duration will be endless, unless a packet count was given. If not
set or set to 0 on remote attacks, the attack duration limit of the
daemon will be used instead.
-U If set, Hyenae will stop the attack when a duration of a random number
of milliseconds between the minimum (-u X or 0 if not set) and the
maximum number (-U X) is reached.
-p Random packet payload. If set, a random data block (payload) of the
given length will be added to the generated packets (if supported by the
chosen attack type). By default all packets will be generated with an
empty data block. If the total length of the packet (including the
protocol headers) exceeds the MTU limit and Hyenae was called without the
-m option, an error occurs. The total length of a packet depends on IP
protocol and the attack type used. The default MTU limit is 1500 bytes.
-P File-based packet payload. If set, the contents of a file at the
given path will be added as the data block (payload) of the generated
packets. If the total length of the packet (including the protocol
headers) exceeds the MTU limit and Hyenae was called without the -m
option, an error occurs. The total length of a packet depends on IP
protocol and the attack type used. The default MTU limit is 1500 bytes.
-m If set, the default MTU limit of 1500 bytes will be ignored and even
packets with a length greater than 1500 bytes will by sent. If the packet
length exceeds the supported MTU limit, pcap will fail to write the data
to the network. You should never provide this option unless you know what
you are doing.
-N No sending (cold run). If set, Hyenae will start a run through its attack
routines without actually writing any data to the network. This can be
very useful to pre-check the generated packets or the remote daemon
behaviour before executing the actual attack.
-l Prints a list of all available network interfaces and exits.
-L Prints a list of all available attacks and exits.
-V Prints the current version of Hyenae and exits.

...
Wildcards are not valid within IP address list files.
-T Untrusted IP address list. Specifies an IP list file which will be
used as a list of untrusted IP addresses. If set, all clients using
the specified IP addresses will not be able to connect to the daemon. An
IP address list has the following format:

milliseconds a single client can request to attack for. If not set or set
to 0, you must specify a packet limit.
-m Maximum number of clients allowed to connect. The default value is 10.
-k Password protection. If set, only clients which are using this password
will be able to control this daemon. Note: Since Hyenae currently does
not support encrypted communication, your password is transferred in
plain text, and can be logged by others.
-f Log-File path. By default, all daemon logs will be written to
/var/log/hyenaed.log on *nix systems or .\hyenaed.log on windows
systems.
-l Prints a list of all available network interfaces and exits.
-V Prints the current version of Hyenae and exits.
--------------------------------------------------------------------------------
5. Address Patterns
Hyenae uses address patterns to define the source and destination address
(and for ARP-Replies, sender and target as well) of the generated packets.
Each pattern can contain wildcards to randomize certain octets or even the
whole address strip or port. Hyenae uses an address adequate randomization
algorithm that makes sure to produce valid addresses. As an example, if you
have a pattern with an IP address strip like 25%.168.0.1, Hyenae will
recognize that it can only place a random value from 0 to 5 here. It will
also use the required notation (decimal or hexadecimal) and detect that the
specified address is an IPv4 address and will use the IPv4 protocol for the
given attack (if possible). Address patterns can have the following formats:
[HW-Address]-[IP-Address]@[Port]
[HW-Address]-[IP-Address]
[HW-Address]
Hyenae will automatically recognize the pattern and even every single
address format (HW, IPv4 or IPv4), so you don't have to pass extra arguments,
since everything we need to know can be derived from the given pattern. If you
want to randomize a complete address strip (HW-Address or IP-Address) simply
put a single % in it:
%-192.1%%.%.%%@%2%
This one will use a random hardware address and a partially randomized IP
address, adequate to the octet digits you specified. Notice that you can
even specify the number of random octet digits to create (but make sure that
the number of digits within the octet is valid for the used format), the last
octet of the IP address strip will be a random 2 digit value. The same works
within the port strip (separated by an '@'), the more wildcards you place,
the more digits the random port number will have. In the example above, the
port number will be 3 digits long and will also have a 2 within its center.
Here are some examples:
// Ok
00:D2:F%:D4:DD:%%-192.168.%%.%@%%
%-192.168.%%%.%@%%
00:D2:F%:D4:DD:%%-%@%%
%-%@%
%-%
// Error: HW address octets have a fixed length of 2 digits!
00:%:00::00:00:00-192.168.0.1@21
If you are using only a single wildcard as the IP address strip, Hyenae will
generate a complete random IP address. By default, Hyenae will interpret or
"assume" random IP address strips as IPv4 addresses. You can change the
assumed version by calling Hyenae with the -A option.
In some cases you will need to randomize a pattern equaly to another one. If
you are generating ARP packets for example, the source hardware address needs
equal the senders hardware address otherwise the packet will be droped by the
target host. In such a case, Hyenae will use an equal randomization on both of
