Researchers discover vulnerability affecting Wi-Fi security

AUSTIN, Tx. -  Security researchers have discovered a Wi-Fi network vulnerability that could allow attackers to steal sensitive information or spread malicious software while someone is logged into a computer or mobile device.  A report published Monday said the breach could only happen if an attacker is within range of the potential victim, but the weakness could affect anyone using a Wi-Fi network, whether at home, the office or at a public coffee shop. &am
