Security Experts Have Bad News for 'Basically Every Device' User

Protocol-level security flaws in WPA2 may affect ALL Wi-Fi devices!

Cybersecurity experts say that executing such an attack is hard, and the chances of it happening on a private connection are low.

You may have heard about a massive new Wi-Fi security vulnerability. This kind of attack does not rely on password guessing. The United States Computer Emergency Readiness Team issued a warning about Krack Sunday, and Britain's National Cyber Security Centre says it is investigating the weakness. On Monday, Vanhoef posted the details of the KRACK vulnerability and dos and don'ts for users on a website called

There is still a question mark on Wi-Fi routers however. In the past, the WEP encryption method was cracked to the point where it became useless and was superceded by WPA and WPA2 in subsequent years.

Vanhoef has responded to the difficulty question in the blog.

This attack technique bypasses established network defenses, including encryption, and works against all modern protected WiFi networks. It is expected that nearly all manufacturers will roll out updates for routers that are now in use with consumers-you will just need to keep an eye out for those on the website of your router's manufacturer-there are different installation and update processes for different router types. "While you wait for an update, you can use your Wi-Fi in hidden mode".

Make sure Wi-Fi is turned off when you're not using it. "We're aware of the issue, and we will be patching any affected devices in the coming weeks". According to The Verge, Microsoft has already released a fix for customers using Windows devices.

The group said in a statement it had advised members to release patches quickly and recommended that consumers quickly install those security updates. Customers who have Windows Update enabled and who applied the latest security updates are protected automatically.

While, I am not typically a fan of sneaky updates, I understand why it was necessary to fix the vulnerability while keeping information about it secret until it was officially disclosed.

Finnish security firm F-Secure said experts have always been cautious about Wi-Fi's ability to withstand security challenges of the 21st century. Note that as protocol-level issues, most or all correct implementations of the standard will be affected. Another expert says home users need not be too anxious, as the attack is "quite. carry out in practice", but that they should update their software whenever an update becomes available.

Most modern Wi-Fi networks have their traffic encrypted by a protocol known as WPA or WPA-2, which has existed since 2003 and until now has never been broken. He also says that the efficacy of the attack depends on how close the victim is to the network. That means your phone, your computer, and even your Wi-Fi light bulbs. It recommended installing vendor updates on affected products, such as routers provided by Cisco Systems or Juniper Networks. Those with status listed as "Unknown" included Google, IBM, Apple, AT&T, D-Link Systems, Microsoft Corporation and others.
