Operation Aurora

Operation Aurora was a 2010 cyber attack that targeted over 30 large companies, including Google and Adobe, in Europe and the United States. It was a sophisticated attack that used many different tools and techniques to steal data from these companies. The attackers were able to get access to sensitive information, such as patent and source code, as well as employee emails. This made it easier for the attackers to steal even more data from these companies. So far, it is not clear who was behind this attack, but it is believed to be a foreign government or group of hackers.
