Wi-Fi Security Tips from Hotline IT<\/h2>\n

Nearly every device we use has Wi-Fi capabilities \u2013 from smartphones to laptops, iPads and TVs. The security protocol WPA2 \u2013 the norm for Wi-Fi password security worldwide can be compromised. It\u2019s fact. This means hackers can potentially exploit the comprise in the code and inject malware such as ransomware into websites and ultimately read your sensitive data. Protecting your network from this threat is top of the list of Wi-Fi security tips your business needs to heed.<\/p>\n

What is KRACK?<\/strong><\/h3>\n

An attacker within range of your Wi-Fi device can exploit the weakness of the WPA2 protocol using a \u201cKey Reinstallation Attack\u201d also known as a KRACK. With this form of attack, hackers can read sensitive information that was previously encrypted. This includes your credit card numbers, passwords, chat messages and emails.<\/p>\n

So what\u2019s the problem?<\/strong><\/h3>\n

Vanhoef found a problem with the code behind the WPA2 encryption protocol. This essentially means that all devices you are using are vulnerable to hackers. They’re easy prey for those trying to intercept internet traffic flowing to and from any device with a Wi-Fi connection. This is a high risk for users when you could be dealing with sensitive information such as your banking accounts.<\/p>\n

How Does This Affect Me?<\/strong><\/h3>\n

For your Wi-Fi to be compromised the hacker needs to be in range of your WiFi network. They can\u2019t attack you outside of your network, for example, from another country. Attackers can\u2019t obtain your Wi-Fi password using this vulnerability. Rather, they can just look at your unencrypted traffic if they know what they\u2019re doing.<\/p>\n

Mr Vanhoef warns that any device that supports Wi-Fi is likely affected by KRACK, but that Linux-based devices, as well as Android devices running version 6.0 or higher of the Android operating system, are especially at risk. At the moment that currently includes more than 40% of Android devices.<\/p>\n
