If you're new here, these three posts are a good place to start. They're representative of what I like writing about: technical rabbit holes, reverse engineering, product systems, and odd corners of the internet.
-
Illegal streams, decrypting m3u8's, and building a better stream experience - A look at illegal sports streams, how they piggyback real services, and what it took to build a better viewing client.
-
Obfuscated javascript, scam emails, and American Express - Reverse-engineering obfuscated JavaScript from scam emails and tracing the campaign back to its command-and-control server.
-
