This weekend I took part in an security challenge. I had great fun doing it but i found a huge gap in my knowledge that I'm really keen to fill and hope someone here can help get me pointing in the right direction.
Midway into the challenge I discovered 2 files that appeared to contain encrypted data, but i could find no clues at to the encryption method or a key that may unlock them.
On the assumption that I'd not just overlooked this information, how could i of started to extract the information from the data? I'd be happy to share the files somewhere if someone can recommend a place to upload?
