The Anonymous hacker community's AntiSec project gave Apple a love tap for the July 4 holiday and, in essence, warned Cupertino to brush up on its security measures. "Not being so serious ... Apple could be target too," the group tweeted. "But don't worry, we are busy elsewhere." Given that Apple has made the iCloud the focal point of its move forward, this could put a crimp in Cupertino's plans as it appears to demonstrate how easily its servers can be hacked into. At the very least, it should put Apple users on guard.
