Reverse Engineering the Speedtest.net Protocol, Gökberk Yaltıraklı

Reverse Engineering the Speedtest.net Protocol

After finishing my command line speed tester written in Rust, I didn't have a proper blog to document this process. A few days ago I wrapped up a simple blogging script in Python so hopefully it works good enough to explain how everything works.

By now I have already figured out the whole protocol for performing a speed test but I will write all the steps that I took so you can learn how to reverse engineer a simple protocol.

The code that I wrote can be found at https://github.com/gkbrk/speedtest-rust.
