COPACOBANA cost ~$10 000 and apparently is as fast as 2500 PCs for the DES cracking it's optimized for, so ~$4/PC-work-unit plus insignificant power costs. You'd need to find someone with experience with implementing crypto in hardware, though. On the other hand, botnets risk detection.
(If you're buying in bulk, ASICs are cheaper, but few will be willing to pay for that much cracking power.)
- marshray 15y agoYeah, I suspect it depends on your bad guys (er, sorry, "threat model") whether or not they feel more comfortable trying to buy botnet time or acquire $10,000 worth of FPGAs in an untraceable way. If I were a bad guy, I would prefer to not have a password-cracking special-purpose supercomputer in my possession. (But I'm not a bad guy, and in fact I would love to have a few around the house. :-)
