APT1 - Exposing One Of China's Cyber Espionage Units

Since 2004, Mandiant has investigated computer security breaches at hundreds of organizations around the world. The majority of these security breaches are attributed to advanced threat actors referred to as the "Advanced Persistent Threat" (APT). They first published details about the APT in their January 2010 M-Trends report. As they stated in the report, their position was that "The Chinese government may authorize this activity, but there's no way to determine the extent of its involvement." Now, three years later, they have the evidence required to change their assessment. The details they have analyzed during hundreds of investigations have convinced them that the groups conducting these activities are based primarily in China and that the Chinese Government is aware of them.
