1. Titan Rain
Target: U.S. military intel
Damages: In 2004, a Sandia National Laboratories employee, Shawn Carpenter (pictured above), discovered a series of large “cyber raids” carried out by what is believed were government-supported cells in China. “Titan Rain” is the name given to these attacks by the FBI, and it was found that several sensitive computer networks were infiltrated by the hackers, such as those at Lockheed Martin and Sandia (owned by Lockheed), but also at the likes of NASA. The danger here is not only can the attackers make off with military intelligence and classified data; they can also leave backdoors and “zombify” machines that make future cyber espionage easier. Titan Rain is considered one of the largest cyberattacks in history.
