All wifi networks’ are vulnerable to hacking, security expert discovers

WPA2 protocol used by vast majority of wifi connections has been broken by Belgian researchers, highlighting potential for internet traffic to be exposed

Mathy Vanhoef, a security expert at Belgian university KU Leuven, discovered the weakness in the wireless security protocol WPA2, and published details of the flaw on Monday morning.

The United States Computer Emergency Readiness Team (Cert) issued a warning on Sunday in response to the vulnerability.

“The impact of exploiting these vulnerabilities includes decryption, packet replay, TCP connection hijacking, HTTP content injection and others,” the alert says, detailing a number of potential attacks. It adds that, since the vulnerability is in the protocol itself, rather than any specific device or software, “most or all correct implementations of the standard will be affected”.
