The hacktivist collective Anonymous celebrated Guy Fawkes Day on Monday by claiming it had stolen data from Symantec and ImageShack servers. Security experts say they have found no evidence that customer data was stolen. The group also claimed to have found a zero-day flaw in ZPanel’s password reset function. Initial reports said Anonymous had hacked PayPal and Zynga, but there was no indication either site had been hacked. In September, AntiSec claimed it stole information on millions of Apple iPhone and iPad users from an FBI agent’s laptop.”]
