NAME

       sucrack - is a multithreaded Linux/UNIX tool for brute-force cracking of local user accounts via su.

SYNOPSIS

       sucrack [options] wordlist

DESCRIPTION

       sucrack is a multithreaded Linux/UNIX tool brute-force cracking tool that drives su(1) with referencing a
       specific user and uses words from a  wordlist  as  passwords.  Running  sucrack  does  not  require  high
       privileges on the target system.

OPTIONS

       sucrack  allows  reading  passwords  from  stdin. In that case, use '-' instead of a filename as wordlist
       parameter.

       Common options:

       -h     print help message

       -a     use ansi escape codes for nice  looking  statistics  (requires  --enable-statistics  configuration
              flag)

       -s <seconds>
              statistics display intervall (requires --enable-statistics configuration flag)

       -c     only print statistics if a key other than `q' is pressed

       -r     enable rewriting of dictionary words (see rules below)

       -w <num>
              number of threads to run with.

       -b <size>
              size of the word list buffer

       -u <user>
              user account to su to

       -l <rules>
              specify certain rules for the rewriting process

       Rewriting rules:

       A      Rewrite word with only upper case characters

       F      Rewrite word with first character as upper case

       L      Rewrite word with last character as upper case

       a      Rewrite word with only lower case characters

       f      Rewrite word with first character as lower case

       l      Rewrite word with last character as lower case

       D      Prepend each digit (0-9) to the word

       d      Append each digit (0-9) to the word

       e      enleet the word

       x      apply all rules to a word

ENVIRONMENT VARIABLES

       SUCRACK_SU_PATH
              The path to su (usually /bin/su or /usr/bin/su)

       SUCRACK_AUTH_FAILURE
              The  message  su  returns  on an authentication failure (like "su: Authentication failure" or "su:
              Sorry")

       SUCRACK_AUTH_SUCCESS
              The message that indicates an authentication success. This message must not be a  password  listed
              in the wordlist (default is "SUCRACK_SUCCESS")
