The latest cyber scare to grip the world has hit and it will effect an unprecedented number of users and devices. KRACK targets the WPA2 security protocol, which is the standard Wi-Fi security protocol for all modern Wi-Fi networks. This means that any device that has ever connected to a modern Wi-Fi network will most likely have been effected. If you value your privacy you need to update all of your devices now.
KRACK stands for Key Reinstallation Attack. A researcher at a Belgian university released information on the startling via a special KRACK website:
“This can be abused to steal sensitive information such as credit card numbers, passwords, chat messages, emails, photos, and so on. The attack works against all modern protected Wi-Fi networks. Depending on the network configuration, it is also possible to inject and manipulate data. For example, an attacker might be able to inject ransomware or other malware into websites.”
The vulnerability affects a core encryption protocol. It can trick a user into reinstalling an already-in-use security key. These keys are supposed to be unique and only used once. KRACK can break up the process of creating new keys for every Wi-Fi connection so that old ones can be reused.
With this vulnerability affecting almost every device that connects to the internet it has never been more important to take the necessary steps to protect yourself when you’re online. The need for a robust antivirus suite has never been more pronounced. We recently looked at the new features introduced into the Avast Premier 2018 suite and we’ve also teamed up with Avast to give away 100 Premier licenses.
On top installing a strong Antivrus suite, there are a number of steps you should take to protect yourself against a KRACK attack:
How to protect yourself against a KRACK attack
1. Avoid Public Wi-Fi at all costs
2. Use an Ethernet cable, wherever possible, to connect to your internet at home
3. Only connect to secure websites and services that use HTTPS. You’ll see this in the URL.
4. If you use a reputable VPN you should activate it permanently until the vulnerability has been patched
As to when KRACK will be patched, we’ll let you know as soon as we hear anything. In the meantime, this threat needs to be taken seriously as it opens up your devices to hackers of all kinds. We’re not just talking about global cyber criminals here. Local mischiefs could detect your home Wi-Fi network and then exploit the vulnerability.
