Simple concurrent web crawler and crawler identifying suspicious typosquatting URLs

Primary LanguagePython

web-crawler

Implementation of a simple concurrent web crawler in Python. The program crawls a single URL (which is input by the user into the program), retrieving all links on that page. Any links found are also crawled and this is repeated until it has found and validated n URLs (n can be input by the user, or is 100 by default), which are output to stdout.

I have extended this to create a suspicious_url_crawler, which generates typos of the 100 most popular domains and crawls these to find valid typosquatting URLs.

Usage

Packages

The following packages are required.

  • requests
  • bs4 (beautifulsoup4)

Run

To run the web crawler program, enter the following terminal command:

python3 web_crawler.py [-v|--verbose] starting_url [--num_urls num_urls_to_scrape]

To run the suspicious url crawler program, enter the following terminal command:

python3 suspicious_url_crawler.py [-v|--verbose] [--num_urls num_urls_to_scrape]

Examples of Suspicious URLs Identified Using suspicious_url_crawler

Many of these are legitimately misleading or malicious, often being filled with spam advertising.
