主题：【纽约时报广告】PLA黑客哪家强，中国山东找蓝翔 -- 路人癸

By examining a series of e-mail addresses, the investigators traced the attacks to hackers who appeared to be based in Chengdu, which is home to a large population from neighboring Tibet. Researchers believe that one hacker used the code name “lost33” and that he may have been affiliated with the city’s prestigious University of Electronic Science and Technology. The university publishes books on computer hacking and offers courses in “network attack and defense technology” and “information conflict technology,” according to its Web site.

调查者确定有一位代号叫“LOST33”的黑客，他来自成都市著名的电子科技大学，该学校发布了电脑黑客的书籍，也开设“网络攻击和防御技术”和“信息战技术”的课程。
