Cyber missiles mean war without bloodshed

"You're seeing an evolution of warfare that's really intriguing," said Phil Lieberman, a security consultant and chief executive of Lieberman Software in Los Angeles. "Warfare where no one is dying."

Cyber warfare, while the subject of thrilling movies and espionage novels, isn't quite revolutionary. "The ability to inhibit [an enemy's] infrastructure has been part of warfare since the dawn of electronic communication," Lieberman said. Cyber missiles are evolving and becoming more sophisticated, targeted and devastatingly effective. And, when done properly and under the radar, you get "outcome without attribution," he said. "That's the beauty of it." What we're talking about is not your typical click-and-disturb computer virus that most of us update to guard against.
