The recent cyber-attack on an Iranian nuclear facility using the Stuxnet virus should worry all of us – not just those in close proximity who were in danger of being blown into the next world by the actions of a computer virus. The recent cyber-attack on an Iranian nuclear facility using the Stuxnet virus should worry all of us. The malware utilised multiple zero-day vulnerabilities and employed a signed digital certificate to authenticate itself.
