Intro This post will try to do a small introduction to the QL language using real-world vulnerabilities that I found in the past, and it will end with a small challenge using QL. A few months ago, I heard of Semmle QL for the first time, what they do is perform multiple code analysis techniques against source code, and dump these results into a database. Then using the QL language, you can query this data to perform variant analysis.
