Python Exploit Pattern Tool

Python implementation of Metasploit's pattern generator and search. Should be python version agnostic, tested and working with Python 2.7.12 up to and including Python 3.9.1

Starts faster and rolls both tools into one.

No extra dependencies required, works with vanilla python

Generate a pattern

$> pattern.py 100
Aa0Aa0Aa1Aa1Aa2Aa2Aa3Aa3Aa4Aa4Aa5Aa5Aa6Aa6Aa7Aa7Aa8Aa8Aa9Aa9Ab0Ab0Ab1Ab1Ab2Ab2Ab3Ab3Ab4Ab4Ab5Ab5Ab6A

Search for a pattern

$> pattern.py Bf4B
Pattern Bf4 first occurrence at position 942 in pattern.
$> pattern.py 0x42346642
Pattern 0x42346642 first occurrence at position 942 in pattern.

Optional automatically copy to clipboard

(Thanks to abeljm for this feature)

If your Python installation has the clipboard package installed, the generated DeBruijin pattern is automatically copied to the system clipboard when it is generated as well as printed to stdout. If the package is missing, the copy to clipboard feature is skipped.

NOTE: On KDE 5 there is an issue with klipper and the clipboard package. You may need to manually run klipper in a terminal before running pattern.py

Use it in your own python code

After placing pattern.py in the same directory as your script:

from pattern import pattern_gen

print(pattern_gen(10))

or

from pattern import pattern_search

found_at = pattern_search('Bf4B')

Obtaining

Clone the repo, or if you are on a machine without git you can use

$> curl https://is.gd/xpattern -o pattern.py

or

$> wget https://is.gd/xpattern -o pattern.py

Or change the pattern.py to whatever filename you like
