Webassembly

The 3rd Annual Binary Golf Grand Prix (BGGP3) is to find the smallest file which will crash a specific program.

Last week a friend of mine asked me to debug/RE some phishing emails that had been sent to them. These phishing emails were visually very clever and looked identical to the real site! But as I looked at the javascript I frankly became embarassed for the developer. Sure, they’d run the code through an obfuscation engine and added some basic anti-debug tricks, but that’s nothing you can’t defeat with AST and proxying function calls.

Let’s build the smallest WASM / GBA ROM / 7Zip polyglot in 584 bytes for the Binary Golf Grand Prix 2021.
