CTF Resources

During the time I have collected various resources that help me practicing CTF skills, divided per each category. Some of the exercises found in these sites are solved in the Security Exercises section.

Web

The repo offer a good collection of XSS related challenges. Although last update is from 2014, it stores a lot of references to other websites with related solution.

The repo offers examples of XSS in different scenarios.

The repo has good reference material to understand XSS and some references to existing challenges.

Reverse

It offers many reverse challenges dividing them in categories as OS, architecture and levels. It does not provide solutions.

Crypto

Very good reference to implementing algorithms. It goes from zero to hero. It helps you to build famous crypto attacks like breaking an MD4 and SHA-1 keyed MAC using length extension. It doesn't offer challenges like broken algorithms to brake or CTF like challenges.

Exploit

Miscellaneous

A collection of write ups from previous CTFs divided per year.
