A company called Bodacion Technologies is offering $100,000 to anyone who can crack their biomorphic number generator and predict the final, one-thousandth, number in a sequence of 999.
The company is doing this to promote its Hydra server, which uses biomorphic computation for crypto routines. Additional security enhancements come from using an embedded OS and not having anything but a Web and Java applet server running. So there's basically a lot less to attack, which is of course inherently more secure than running hundreds of services.
To claim the $100K, all one needs to do is obtain the 999 numbers and accurately predict the thousandth one, and explain how it was done (guessing doesn't count).
In addition to the number challenge, the company also has a Hydra box at 18.104.22.168 which it invites you to own if you can. There's no prize for the CTF challenge; but perhaps one might get a Bodacion t-shirt or coffee mug, and of course a mention in The Register, if one should succeed.
Happy cracking. ®
