Stuxnet is Much Older than We Thought
Schneier on Security 2013-03-15
Summary:
Symantec has found evidence of Stuxnet variants from way back in 2005. That's much older than the 2009 creation date we originally thought it had. More here and here.
What's impressive is how advanced the cyberattack capabilities of the U.S. and/or Israel were back then.
