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")
