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
