According to Edward Snowden NSA and Isreal worked together to create Stuxnet, a computer worm that was used to attack Iran’s nuclear facilities. It was spread via Microsoft Windows and its target was industrial control systems by Siemens. After that, a more sophisticated virus called Flame was linked with Stuxnet. Kaspersky researchers concluded that the creators of the Flame were the same that also created Stuxnet due to the similarities in the code. So, if what the whistleblower says is true then NSA created both malicious software. I guess they created more than the ones we just learned about. But don’t worry, they create malicious software, worms and viruses to protect you, at least this is what they will say if you ask them. They don’t want to but they have to in order to protect the people.
