Assistant Attorney General Leslie R. Caldwell, of the Justice Department’s Criminal Division, said "the American economy is driven by innovation. But American innovation is only valuable when it can be protected. Today's guilty pleas show that we will protect America's intellectual property from hackers, whether they hack from here or from abroad."

He added: "As the indictment charges, the members of this international hacking ring stole trade secret data used in high-tech American products, ranging from software that trains U.S. soldiers to fly Apache helicopters to Xbox games that entertain millions around the world."
