Are the Chinese after us? According to a new report, yes. Security firm Mandiant has detailed the exploits of a Chinese cyber espionage group it calls APT1. Mandiant claims to have evidence that APT1 has stolen "hundreds of terabytes of data" from 141 American organizations. Evidence that includes this video of an elite Chinese hacker in action.

In other words, the report confirms what educated observers have been saying for ages: That the Chinese military is after our secrets. Watch the video for a narrated blow-by-blow of an APT1 attack. The video may not be quite as riveting as a spy movie, but it's captivating—and plenty terrifying—nonetheless. [Mandiant via Washington Post via Digg]
