comment What would you define as an “advanced” hacker attempt?
Advanced: A breakin that doesn't make you think "How stupid I/we/somebody involved was!"

comment Compute the AES-encryption key given the plaintext and its ciphertext?
@Morons: You're not going to recover the key by brute force attack only using the entire resources of the solar system until it's all cold and dead, unless you're really really lucky. IIRC, AES encrypts units of 64 bits, so a rainbow table would need 2^128 entries, which you aren't going to be able to generate given said resources. The danger is that repeated plaintext will generate repeated ciphertext using AES naively, and that may give the attacker some information.

comment What type of captcha will you recommend?
Aside from the manpower solution, there's the fact that image recognition and OCR is very good nowadays, and it's hard to reliably get one that humans can answer and bots can't.

comment What type of captcha will you recommend?
Aside from the obvious problem that most people will not be able to solve it, there's the less obvious problem that there's probably a fairly small number of these, and the answers can be precalculated and entered automatically.
