Every Wi-Fi connection is potentially vulnerable to an unprecedented security flaw that allows hackers to snoop on internet traffic, researchers have revealed.
The vulnerability can be exploited by hackers to steal personal information such as your credit card numbers, passwords, emails, photos, and more.
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.
While the KRACK Wi-Fi exploit exposure has made billions of devices vulnerable, Windows users with enabled automatic updates can stay at ease. For this sort of an attack to be mounted on your Wi-Fi network, a hacker has to be within the range of the network-this can not be remotely.
"During our initial research, we discovered ourselves that Android, Linux, Apple, Windows, OpenBSD, MediaTek, Linksys, and others, are all affected by some variant of the attacks", he continued. Microsoft says it's already deployed patches.
Even if you were bored enough to actually click on the More info button, you would have had to be REALLY bored to even spot a reference to a vague mention of a wireless security update in the last bullet item of the knowledge base article.
It's safe to say this newfound weakness poses a serious privacy risk - here are a few things you can do to protect yourself from a potential attack.

Danny Murphy categorically argued with Wenger's claim the decision was scandalous. It was not a penalty, it was a creation of the referee.
Now since the vulnerability is so widespread, tech giants will have to speed up the patch process and issue updates to their users as soon as possible. Google says it is working on a patch, and Microsoft says it's already released a security update to fix the issue.
In the meantime, avoid connecting to public Wi-Fi networks.
"The attack works against all modern protected Wi-Fi networks", Vanhoef writes.
As I've previously written, the padlock indicates that traffic to and from a site is encrypted - via the HTTPS protocol- which basically means no one but that site can read any sensitive information you share.
"Wi-Fi Alliance now requires testing for this vulnerability within our global certification lab network and has provided a vulnerability detection tool for use by any Wi-Fi Alliance member".
