"Software attacks that stop the physical hardware from ever working again are known as Permanent Denial of Service (PDoS) attacks. The Stuxnet virus -- which attacked Iran's nuclear facilities -- was so complex that many security companies concluded it must have been the work of one or more government agencies rather than individual hackers.

"Think about it -- you can "brick" an iPhone or iPod accidentally when you try and jailbreak it," he pointed out. Back in 2008 at EUSecWest, HP researcher Rich West demonstrated that NAS, security and networking appliances can be vulnerable to malware that downloads malicious firmware and flashes the appliance with it, rendering the hardware unusable. For that reason there has been a trend toward ensuring that appliance firmware updates are digitally signed by the manufacturer."
