The New York Times is reporting that members of China's most advanced hacking group have been traced to the same small neighborhood as a Chinese Army base, a revelation that all but confirms that the Chinese military is behind the attacks. The hackers, known as the "Comment Crew," have targeted various parts of the U.S. government as well as major corporations like Coca-Cola and, more troubling, a company that has remote access to more than 60 percent of the oil and gas pipelines in North America. Mandiant, the same American computer security company the Times used to rid its networks of hackers last year, traced hundreds of attacks — 90% of the ones they examined — to the Shanghai neighborhood that houses the base, called P.L.A. Unit 61398.
