Major flaw threatens most wi-fi networks, warns cyber watchdog

Are you affected?  The most likely answer to this question is - yes you are!  Unless all the devices (laptops, smart phones, tablets etc) on your Wi-Fi network have had an update applied then yes, you are likely vulnerable as a result of this flaw.  For Windows devices, Microsoft have released a patch and we have applied this patch to all devices covered by our Managed Service.  Smart phone and tablet devices will have updates released from the device manufacturer or mobile carrier in many cases.  We recommend getting all of your staff to apply any updates released recently to ensure you have the latest patches applied.

A top United States government cybersecurity watchdog issued an advisory about the attack, called Krack (Key Reinstallation Attack), warning users to update their devices. The US Computer Emergency Readiness Team's announcement comes after a security expert at the University of Leuven in Belgium published findings that showed that a widely used encryption system for wireless networks could give attackers an opening to steal sensitive information such as emails, chat histories and credit card numbers.

The exploit would allow hackers to eavesdrop on internet traffic between computers and wireless access points. The findings are significant because of the wide range of devices that could be affected.

​"The attack works against all modern protected wi-fi networks," Mathy Vanhoef said on a website he created to share his research.
