New Scientist:Why is this important? Because Diebold is one of the companies making electronic voting systems, and they're being particularly obnoxious about any claims that their systems might have security issues.
"Cash dispensing ATMs belonging to two US financial institutions were shut down when the computer worm Welchia invaded their embedded Windows XP operating systems in August. Diebold, the Ohio-based company that makes the machines, revealed the security breach on Tuesday.
It is the first known case of a worm actually installing itself on individual ATM operating systems, says Peter Lind, a security expert at Spire Security in Malvern, Pennsylvania. Earlier in 2003, the Blaster worm shut down Bank of America ATMs, but only by causing a flood of traffic that clogged the network's bandwidth."
