You may think your Wi-Fi is secure, and you’ve had good reason to, with the long-term success of WPA2 authentication keeping us relatively secure on wireless networks. Regardless of how good your password is or whatever kind of safety settings you have, though, experts say someone could be watching everything you’re doing – or worse, compromising your wireless security, possibly, the next time you log on to a public Wi-Fi hotspot and are worried about Wi-Fi hackers.
This latest Wi-Fi security flaw was discovered by a Belgian computer security researcher. The wireless security vulnerability known as KRACK allows someone to be able to download a tool that would let them get into anyone Wi-Fi who’s in close enough proximity to it.
The security protocol used to protect most Wi-Fi connections has been broken, potentially exposing wireless internet traffic to Wi-Fi hackers and cyber attacks, according to the researcher who discovered the weakness.
Mathy Vanhoef, a security expert at Belgian university KU Leuven, discovered the weakness in the wireless security protocol WPA2, and published details of the flaw last Monday morning (October 16th).
“Attackers can use this novel attack technique to read information that was previously assumed to be safely encrypted,” Vanhoef’s report said. “This can be abused to steal sensitive information such as credit card numbers, passwords, chat messages, emails, photos and so on.
Vanhoef emphasized that “the attack works against all modern protected Wi-Fi networks. Depending on the network configuration, it is also possible for Wi-Fi hackers to inject and manipulate data. For example, an attacker might be able to inject ransomware or other malware into websites.”
The vulnerability affects a number of operating systems and devices, the report said, including Android, Linux, Apple, Windows, OpenBSD, MediaTek, Linksys, and others.
“If your device supports Wi-Fi, it is most likely affected,” Vanhoef wrote. “In general, any data or information that the victim transmits can be decrypted. Additionally, depending on the device being used and the network setup, it is also possible to decrypt data sent towards the victim (e.g. the content of a website).”
Vanhoef gave the weakness the codename KRACK, short for Key Reinstallation AttaCK.

Enter Insight Technologies’ bid to free North Dakota business owners from the menace of Wi-Fi security vulnerabilities and exploits.
Cyber security expert Jeremy Van Dyke of Insight Technologies has this to say on the subject of the KRACK Wi-Fi security vulnerability: “It’s not something that can be done remotely. There is not a threat of Chinese hackers that are going to be able to get into your home network. They have to be physically near enough to your wireless router to be able to connect to it.”
Van Dyke’s best advice on beating potential Wi-Fi hackers is to use an ethernet cord to connect to the internet. However, he knows that’s not always possible. He says if you are using a secure website, like your bank, that website is encrypted and your information should be secure, even if your wireless network is hacked.
If someone does get into your network, the unsecured websites are the problem. “The bigger threat is the social media.” Van Dyke says if you are using the same password for multiple sites you are opening yourself up to a lot of vulnerabilities. “Once they are able to see a username and password then it’s just a matter of time to see where else you are able to see that password.”
Van Dyke says cellphones are an even bigger threat. “Everyone wants to save data, and connect to Wi-Fi, often times unsecured Wi-Fi. And, who knows how many people are spying on you through there. Unless you really know where you are and can trust it, your data plan is going to be safer.”
Another thing Van Dyke recommends is looking at your settings on your phone. Often people have auto-connect turned on, which allows your device to get onto Wi-Fi without asking your permission. He says that’s opening you up to a lot of vulnerability.
Regardless of what device you are on, or whose Wi-Fi it is, Van Dyke – like other cybersecurity experts – believes this new discovery should put everyone on alert.
Which is where Van Dyke and the Insight Technologies team comes in – acting as a bellwether for Grand Forks and Fargo, ND business owners of all sizes, and who want to proactively step-up their Wi-Fi security protections.
