The recent spearphishing attacks on security firm RSA and on the International Monetary Fund are both suspected of being attacks by foreign powers to steal data that could be used in a cyberoffensive against the United States. In fact, the CIA website and the U.S. Senate were also breached by the hacking group LulzSec, and government contractors Lockheed Martin and Booz Allen Hamilton were attacked more recently. Cyberattacks on U.S. assets aren't necessarily anything new, but the rash of recent high-profile break-ins has led the current administration to take a hard stance and draw a line in the sand.
