Do you use a Wi-Fi router? I would recommend you read this Reuters news service article.

 

(Reuters) - Cyber security watchdogs and researchers are issuing warnings over risks associated with a widely used system for securing Wi-Fi communications after the discovery of a flaw that could allow hackers to read information thought to be encrypted, or infect websites with malware.


An alert from the U.S. Department of Homeland Security Computer Emergency Response Team on Monday said the flaw could be used within range of Wi-Fi using the WPA2 protocol to hijack private communications. It recommended installing vendor updates on affected products, such as routers provided by Cisco Systems Inc or Juniper Networks Inc.


Belgian researchers Mathy Vanhoef and Frank Piessens of Belgian university KU Leuven disclosed the bug in WPA2, which secures modern Wi-Fi systems used by vendors for wireless communications between mobile phones, laptops and other connected devices with Internet-connected routers or hot spots.

"If your device supports Wi-Fi, it is most likely affected," they said on the www.krackattacks.com website, which they set up to provide technical information about the flaw and methods hackers might use to attack vulnerable devices.

 

It was not immediately clear how difficult it would be for hackers to exploit the bug, or if the vulnerability has previously been used to launch any attacks.

Finnish security firm F-Secure said experts have long been cautious about Wi-Fi's ability to withstand security challenges of the 21st century.

 

"But the worst part of it is that it's an issue with Wi-Fi protocols, which means it affects practically every single person in the world that uses Wi-Fi networks," it said on its website.

Microsoft Corp said it had released a security update for Windows. Customers who applied the update, or had automatic updates enabled, would already be protected, it said in a statement emailed to Reuters.



CERT New Zealand and CERT India asked users to apply security updates. CERT NZ suggested using ethernet cables and to connect directly into the network, when possible.

"Given the complexity of updating smart devices such as mobile phones, CERT NZ also strongly recommends disabling Wi-Fi when it isn't required," it said in its advisory. (http://bit.ly/2gfho2b)


The Wi-Fi Alliance, an industry group that represents hundreds of Wi-Fi technology companies, said the issue "could be resolved through a straightforward software update".

The group said in a statement it had advised members to release patches quickly and recommended that consumers quickly install those security updates.

I got to thinking about this vulnerability this evening and it's not just laptops & smartphones one should be concerned about. With more consumers using all kinds of smart devices that connect to the wireless network in their homes or businesses this possibly could become a bigger issue than researchers are willing to admit or originally thought. If a hacker can find a way they'll certainly take advantage of any vulnerability, it's just a matter of time & effort.

 

Think about it, there's smart light switches, door locks, door bells, heating/cooling thermostats, baby monitors, televisions, security alarm systems, security cameras and smoke alarms to name just a few that can use a Wi-Fi connection these days. Just how vulnerable does that make these devices to hacking as well? This, in my opinion, makes it imperative that Wi-Fi router manufactures issue firmware security updates/patches & consumers install them ASAP!
