[sc name=”ad_1″]

Selenium based web scraper to generate passwords list.

Installation

# Download Firefox webdriver from https://github.com/mozilla/geckodriver/releases
$ tar xzf geckodriver-v{VERSION-HERE}.tar.gz
$ sudo mv geckodriver /usr/local/bin # Make sure it is in your PATH
$ geckodriver --version # Make sure webdriver is properly installed
$ git clone https://github.com/dariusztytko/words-scraper
$ sudo pip3 install -r words-scraper/requirements.txt

Use cases

Scraping words from the target’s pages

$ python3 words-scraper.py -o words.txt https://www.example.com https://blog.example.com

Such generated words list can be used to perform online brute-force attack or for cracking password hashes:

$ hashcat -m 0 hashes.txt words.txt

Use –depth option to scrape words from the linked pages as well. Optional –show-gui switch may be used to track the progress and make a quick view of the page:

$ python3 words-scraper.py -o words.txt --depth 1 --show-gui https://www.example.com

Generated words list can be expanded by using words-converter.py script. This script removes special chars and accents. An example Polish word źdźbło! will be transformed into the following words:

  • źdźbło!
  • zdzblo!
  • źdźbło
  • zdzblo
$ cat words.txt | python3 words-converter.py | sort -u > words2.txt

Scraping words from the target’s Twitter
Twitter page is dynamically loaded while scrolling. Use –max-scrolls option to scrape words:

$ python3 words-scraper.py -o words.txt --max-scrolls 300 --show-gui https://twitter.com/example.com

Scraping via Socks proxy

$ ssh -D 1080 -Nf {USER-HERE}@{IP-HERE} >/dev/null 2>&
$ python3 words-scraper.py -o words.txt --socks-proxy 127.0.0.1:1080 https://www.example.com
