Stuxnet copycats: Let the hacking begin

Last March on 60 Minutes, Steve Kroft unraveled the mysterious Stuxnet computer virus, which he calls "the most sophisticated cyber weapon ever invented."

About two years ago, the all-important centrifuges at Iran's nuclear fuel enrichment facility at Natanz began failing at a suspicious rate. Computer security experts now agree that the sophisticated computer worm dubbed Stuxnet was behind it.

Although the identities of Stuxnet's designers have been the subject of endless speculation and anonymous leaks to reporters, the code itself is no secret. Hackers -- and our own producer Graham Messick -- found it simply by looking on the Internet.

Could international hackers exploit the Stuxnet code and design similar viruses that target critical infrastructure in the United States?

"At its core, Stuxnet was an elegant and novel weapon, one that could be reverse-engineered and repurposed," says Messick. 60 Minutes Overtime explores the possibility of Stuxnet-style catastrophe on American soil.
