Don’t let your Wi-Fi KRACK – Upgrade Patches available NOW

Most of you will now be aware of the KRACK Wi-Fi flaw that emerged over the last couple of days.

KRACK stands for Key Reinstallation Attack and allows hackers to eavesdrop on virtually every internet connected device via a flaw in WPA2 (or Wi-Fi Protected Access 2). WPA2 networks are the current industry standard for protecting against eavesdroppers. They’ve been in use since 2004, so they’re everywhere, but it’s only recently that Belgian security researcher Mathy Vanhoef identified a flaw that could give hackers the opportunity to “steal your passwords, intercept financial data, or manipulate commands to send money to themselves” (source:

There is also the potential for hackers to inject ransomware or other malware into websites. Offenders need to be within range of a Wi-Fi network in order to capitalise on this flaw, but with WPA2 enabled on tens of millions of devices globally, that offers little consolation.

According to The Age, the Australian Cyber Security Centre is investigating the issue, but in the meantime Australian organisations and individuals should “patch or update your software and applications when new versions become available”.
