I know it's science-fiction, but the 2010 book <a href="http://en.wikipedia.org/wiki/The_Quantum_Thief>The Quantum Thief</a> makes use of weapons like these: basically firing a missile to get physical access to your adversary's computer systems with some sort of payload, and that payload of which will scan and disrupt the opponent's system.
Physical attack on enemy corporation was just a diversion.
The real attack was on corporation network. Main computer gone nuts and started selling and buying in most ineffective way. Corporation was destroyed after several minutes.
