When we talk about improvements in international communication, this isn't what we mean. A Chinese hacking operation targeted at least 20 defense contractors worldwide over the course of two years, the New York Times reported on Friday. The hackers reportedly have a strong focus on drone technology, and affected companies believe they are looking to turn China into a world leader in drone manufacturing for both domestic use and export. The country's Foreign Ministry even claims to be a victim itself. But here's where things get complicated: the hacking group, called the Comment Crew, has been tracked to a People's Liberation Army building near Shanghai.
