Almost a third of the world's encrypted Web connections can be cracked using an exploit that's growing increasingly practical, computer scientists warned Wednesday. They said the attack technique on a cryptographic cipher known as RC4 can also be used to break into wireless networks protected by the Wi-Fi Protected Access Temporal Key Integrity Protocol.
