Description

A password protected neural network stored in a custom binary format. Your goal: extract the hidden flag. The model file (model.nli) is a tiny trained MLP that acts as a password gate. Feed it the right password and it will reveal the flag but there's no explicit password check in the code. To solve it you'll need to: reverse the custom .nli binary format, decrypt and parse the model weights, implement inference for a neural network, and search for the password the model was trained to accept.
