# Awesome Sec Challenges [![Awesome](https://awesome.re/badge.svg)](https://awesome.re)

A curated list of Awesome Security Challenges that is aimed at getting beginners and experts alike involved in upskilling their ethical hacking, pentesting, and crypto skill through online challenges.

There are a lot of great security challenges on the Internet, but it's hard to keep track of them all or work on different types of challenges. This list helps keep all those scattered platforms in one place.
