For example, in 2008 Chinese intruders based in Shanghai and linked to the People’s Liberation Army used a computer document labeled “salary increase — survey and forecast” as bait as part of the sophisticated intrusion scheme that yielded more than 50 megabytes of electronic mail messages and a complete list of user names and passwords from a United States government agency that was not identified.

In most cases the intruders took great pains to conceal their identities, but occasionally they let their guard down. In one case described in the documents, investigators tracked one of the intruders who was surfing the Web in Taiwan “for personal use.”
