Insider threats are real. The worrying aspect of this story is the fact that Xu had worked for IBM for about 4 years, thats a long time to gain access to a lot of information.

Xu pled guilty and could face up to 15 years for economic espionage.
Xu Jiaqiang, 30, a former software engineer for IBM, pleaded guilty on Friday to charges of economic espionage after the FBI had caught him attempting to sell IBM's source code, and later discovered he sold it to parties in China.
