π©βπ» Expimont challenge - reversed
Deobfuscated challenge of the Expimont WAF JavaScript challenge
β How it works
The JS challenge sets a cookie based on testcookie_enc_set
. It uses the value of testcookie_enc_set
to call some functions and generate an object. This object is then passed to the decryption function to generate the cookie. Afterwards you get redirected to the page. The decryption object can be dumped at the point where the cookie is being set in order to statically generate the cookie.
