Duncan Hollis, an international law and foreign affairs expert at Temple's Beasley School of Law, joined CNN's "American Morning" to discuss a massive cyber-espionage scheme targeting U.S. corporations, non-profits, government agencies and defense contractors. Some speculate the attack had roots in China. "Dozens of governments" have set up their own "cyber-commands," Hollis explained, "making the environment much more complicated in terms of the various actors that are now out there — not just cyber-criminals any more, but actual military operations in cyberspace."
