sucrack

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

sucrack [options] wordlist

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 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

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")
