Stuxnet is a huge virus that was discovered last July. What sets it apart from other viruses is its invisibility meaning any system it hacks, the security system won’t realize anything has happened. Most importantly, it is a virus capable of killing, triggering bombs, shutting down security of any kind and pretty much do anything. The person(s) behind it are unknown but what is more scary is that the code is available online and it is open-source. Watch the infographic for more, and even more on Wiki.
