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.

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")

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

       Commonoptions:-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

       Rewritingrules: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
