We all use Wi-Fi for, well, basically everything. Outside of my job as a systems programmer, I use my home’s Wi-Fi for my iPhone 8, MacBook Pro, Amazon Echo, and Amazon Fire TV Stick (so I can watch my favorite shows!). So, when I discovered that hackers could possibly steal any information that I sent over a Wi-Fi network, I panicked. I’m sure most of my blog readers are already aware of the newly discovered Wi-Fi vulnerability. But if you aren’t, here’s what you need to know.
Belgium researchers recently found a flaw in the code for WPA2; this is an essential function in basically every wireless connection. That’s why this problem is so universal – it applies to pretty much every Wi-Fi connection and device out there. This flaw, known as KRACK (Key Reinstallation Attack), allows hackers to monitor all of the Internet activity associated with any connected devices. While they can only access this information if they’re physically nearby, you never know if there’s a hacker in the cafe with you.
Right now, there isn’t an immediate solution for this flaw. Changing your Wi-Fi password or buying a new router won’t help at all. We just have to sit tight until patches and updates are available. Be sure to update your device(s) regularly, as well as your router. If you’re a Windows user, you’re in luck – Microsoft rolled out an update that protects its devices from this Wi-Fi vulnerability. In the meantime, companies such as Amazon, Netgear, Google, and Apple are currently working on patches to protect their customers’ devices. You’ll have to keep an eye on the latest tech news to find out when you can expect these updates.
While you wait for these crucial updates, you can use a virtual private network (VPN). This will add an extra layer of encryption to the data you send and receive while you use the Internet. I personally use one for all of my web browsing outside of the office. If you need any VPN recommendations, feel free to email me. I can help you find one that’s right for you.
