SYNFlood.py - A multithreaded SYN Flooder

January 18, 2013 at 12:00 PM

I wrote this script a long time ago when I was just starting to learn about networking basics. During that time, I came across a Python library that makes it easy to craft and manipulate network traffic at a packet level by the name of Scapy.

I wrote this script as a demonstration of a SYN/ACK Three Way Handshake Attack as discussed by Halla of Information Leak in an article that has since mysteriously disappeared from his site. I also mentioned this script in an article I wrote about hacking gibsons or something to that effect, that I have since removed form this site because the writing in it was atrocious. (Well it was written by a ninth grader, so that's not a huge surprise.)

Anyway, aside from searches for the phrase "How can you say you love her if you can't even eat her poop?" (oh yeah, I'm an SEO master), the majority of external search engine hits to my website come from people looking for this script. Therefore, I decided I'd spruce it up a touch, and repost it in all of its glory here.

So without further adieu, gaze and behold!

Pokebot (poh-kay-bot) - A Facebook Poke Autoresponse Bot

January 3, 2013 at 12:00 PM

== Source code available on my Github. ==

A friend of mine asked me to write him a bot that would automatically poke back anyone who poked him on Facebook, so that's what I did.

This bot doesn't make use of any of the actual Facebook APIs, but instead performs all of its actions by mimicking the behavior of an actual web browser. I designed it this way for three reasons.

  1. I was bored and enjoy a challenge.
  2. It takes me back to my days as a freelance spam bot developer.
  3. Working with official APIs can be messy when you have to deal with getting access tokens, and the possibility of having your access revoked if your actions are deemed excessive. So while it's not nearly as straight forward as working with the official API, mimicking a web browser does have its perks.


Requirements


Usage

Assuming you meet all the requirements listed above, all you need to do is run main.py Pokebot will ask for your Facebook email and password, as well as an amount of time to wait between checking for pokes. Once all of that information is squared away, Pokebot will run on a continuous loop until you tell it to stop.

Randomized User Agent Header Generator

October 24, 2012 at 12:00 PM

I put together a scraping bot for a website I frequent occasionally, but they got wise to my Python shenanigans after I released the source code (who'd have thought?), so I had to step up my bot code a bit.

After some tinkering I found that they had just blacklisted the user agent header I was using for the script, instead of doing something more effective like setting access timers between page requests, or getting strict on referer headers, or just banning my account.

But I digress...

Since all they did was ban the user agent string I was using before, all I had to do was change it , and I was back in business. But in the long run this isn't really the best solution since they could always just ban the user agent header again. So instead I decided to throw together a quick Python function that generates a randomized, realish looking user agent header.

Gaze and behold!

def get_random_useragent():
              base_agent = "Mozilla/%.1f (Windows; U; Windows NT 5.1; en-US; rv:%.1f.%.1f) Gecko/%d0%d Firefox/%.1f.%.1f"
              return base_agent % ((random.random() + 5),
                               (random.random() + random.randint(1, 8)), random.random(),
                               random.randint(2000, 2100), random.randint(92215, 99999),
                               (random.random() + random.randint(3, 9)), random.random())
          
          >>> print get_random_useragent()
          Mozilla/5.2 (Windows; U; Windows NT 5.1; en-US; rv:2.5.0.5) Gecko/2009098692 Firefox/3.3.0.4
          >>> print get_random_useragent()
          Mozilla/5.5 (Windows; U; Windows NT 5.1; en-US; rv:3.3.0.7) Gecko/2006095233 Firefox/3.2.0.2
          >>> print get_random_useragent()
          Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.1.0.4) Gecko/2064093484 Firefox/4.4.0.8
          >>> print get_random_useragent()
          Mozilla/5.6 (Windows; U; Windows NT 5.1; en-US; rv:7.5.0.6) Gecko/2063099117 Firefox/3.6.0.6
          

I hope someone out there besides me can find a use for this.

Gentle Brute

December 3, 2011 at 12:00 PM

== Source code available on my Github. ==

One of the major drawbacks to using a brute force attack to crack a password, is that it can literally take billions of years (if not more) to try all of the possible permuations of a user's password. One way to cut down on this, is to skip trying passwords that would be unlikely for a target user to have. (Things like 'aaaaaa', 'asdf7777772dn', etc) Gentle-Brute is a Ruby gem designed to generate only "English-like" words and phrases for more heuristic brute force password cracking attacks. An English-like word is a sequence of characters that may not necessarilly be an actual English word, but still adheres to the "rules" of English words. By only using these kinds of words and phrases when attempting to crack a password with brute force, it's possible to greatly reduce amount of time it takes to find a matching hash.


What are the "Rules" of English-like words and phrases?

Please see my article Building the Better Brute Force Algorithm - A Guide to Heuristic Password Cracking for a detailed explanation of this subject.


Installation

Rubygems

gem install gentle_brute
          

Github

git clone git@github.com:jamespenguin/gentle-brute.git
          gem build gentle_brute.gemspec
          gem install gentle_brute-<version>.gem
          


Usage

Gentle-Brute includes a handy dandy pre-written application (GentleBrute) for crackng MD5 hashes, or you can write your own custom password cracking programs.

Using GentleBrute

~/GentleBrute --help
          GentleBrute [options]
          
          options:
          
                  --word-list                Generate a word list of valid English-like words and phrases for a given length
                  --cross-compare-crack      Cross compare brute force cracking times for a given md5 hash between GentleBrute, and regular brute forcing.
                  --validate                 Test whether a given word or phrase is considered valid
                  --crack-md5                Crack a single MD5 password hash
                  --crack-md5-list           Crack a series of MD5 password hashes in a given file
                  --rainbow-table            Build MD5 hash rainbow table
              -h, --help                     Print this help message
          

Writing Your Own Password Cracker

require 'digest/md5'
          require 'gentle_brute'
          
          target_hash = '58e53d1324eef6265fdb97b08ed9aadf'
          
          b = GentleBrute::BruteForcer.new
          while true
            phrase = b.next_valid_phrase
            attempt_hash = Digest::MD5.hexdigest(phrase)
            puts "Password is #{phrase}" if attempt_hash == target_hash
            break if attempt_hash == target_hash
          end
          


Is there really a big difference in speed?

You bet there is!


But does it really work?

See for yourself!

gem install gentle_brute
          wget https://raw.github.com/jamespenguin/gentle-brute/master/passwords.txt
          GentleBrute --crack-md5-list passwords.txt

Decaptcher API Python Module

October 13, 2011 at 12:00 PM

Decaptcher is a website that offers automated CAPTCHA image solving for the price of a fraction of a penny per image. They offer round the clock CAPTCHA solving, which they claim is all done by humans over on their end, which leads me to believe that there is some massive sweatshop somewhere in India wherein there are several hundred small children being forced to solve CAPTCHAs all day. Oh well, it makes for a great tool for writing bots.

Decaptcher doesn't have an official Python API, so I cooked up my very own based off of their terrible documentation, enjoy!

Usage Example

import decaptcher
          d = decaptcher("username", "password")
          print "You have $%.2f left on your Decaptcher balance." % d.get_balance()
          print "CAPTCHA image answer is: %s" % d.solve_image(path_to_image_file)
          

This module requires Requests

              new_line = []
              for a in range(line_len):
                  if a == 0 or a == line_len - 1:
                      new_line.append(1)
                      continue
                  new_line.append(last_line[a] + last_line[a-1])
              print new_line
              last_line = new_line
