Unbelievably, it appears that spammers are able to achieve a 5% gain on pumped stock before dumping it, along with a dramatic increase in transaction volume of the stock. Paper summary, full paper."

giorgiofr (887762) writes "How to steal an election by hacking the vote: Ars Techinca has a nice write-up detailing how to rig elections on Diebold machines. Some conclusions: "The problem is much deeper than most people realize. The standards are extremely weak (1990 and 2002 both), and VOLUNTARY. The systems are built to minimum standards rather than attempting to be meaningfully secure. The evaluations are commissioned and paid for by the vendors, and are proprietary. The entire voting process consists of weak links.""
