First precaution for Wi-Fi breach came from Microsoft

First precaution for Wi-Fi breach came from Microsoft

This is specifically linked with the WPA2 security protocol, an exploit for which allows attackers within the physical proximity of a vulnerable device or wireless access point to intercept passwords, read e-mails, and other traffic that is now running on that network. "We updated to protect customers as soon as possible, but as a responsible industry partner, we withheld disclosure until other vendors could develop and release updates".

Android 6.0 and above, along with many Linux variants, use a newer version of the wpa_supplicant application that is the vector for this variation of the attack.

2. Avoid using public Wi-Fi networks.

While Windows users were dutifully installing October 10th's Patch Tuesday security updates, little did they know they were also installing a fix for the KRACK vulnerability that was not publicly disclosed until today.

We all love to be connected on Wi-Fi, but the very same Wi-Fi that we are using has a serious vulnerability.

Mulvaney: We'll Help Puerto Rico Rebuild; Must 'Fix Itself' From Debt
Trump visited relief camps meeting the survivors and distributed supplies even throwing paper-towel rolls into the crowd . In another missive, Trump said too many people in Puerto Rico "want everything to be done for them".

A recently uncovered Wi-Fi vulnerability poses real security risks, Vladimir Kuskov, an analyst at the Russian software company Kaspersky Lab, said. Not only are routers and switches affected though, but there are millions upon millions of internet of things devices which will be much harder to update to fix this problem.

Manufacturers and vendors have promised updates that are already available or will be soon.

The hacker would have to be within Wi-Fi range to carry out any of those exploits. That means your phone, your computer, and even your Wi-Fi light bulbs. And you can watch the video above for additional information. The Krack vulnerability, which was identified by a security researcher overseas affects nearly all devices including computers, mobile phones, routers and smart TV.

Finally, consider browsing the Web with an extension or browser add-on like HTTPS Everywhere, which forces any site that supports https:// connections to encrypt your communications with the Web site - regardless of whether this is the default for that site. Apple, Android and Windows software are all susceptible to some version of the vulnerability, which is not fixed by changing Wi-Fi passwords. "Users can expect all their Wi-Fi devices, whether patched or unpatched, to continue working well together", the statement said.
