Security researchers have discovered a huge flaw in WiFi that affects just about every gadget we use and could give hackers easy access to our networks and our devices.
The flaw, know as Krack, uses a weakness in the WPA2 protocol, which is used to secure all modern WiFi networks.
“Attackers can use this novel attack technique to read information that was previously assumed to be safely encrypted,” Vanhoef, from the research team at Belgian University KU Leuven, wrote. “This can be abused to steal sensitive information such as credit card numbers, passwords, chat messages, emails, photos, and so on.”
This means an attacker could trick someone’s device into connecting to their Wi-Fi access point, instead of the one to which they’re trying to connect.
But the Belgian team has found a way to break into this connection, which could enable hackers to access the encrypted data travelling within it, including passwords, credit card details and private messages sent over the WiFi network.
what should we do now?
Speaking to HuffPost UK, Jarno Niemelä, Lead Researcher at F-Secure Labs explains the advice actually doesn’t change for normal consumers.
“The good news is that security advice doesn’t really change. Public WiFi is always thought to be untrustworthy and users should always use a VPN. And home and other WiFi access points under the user’s control should always be updated with latest ROM versions anyway.” he says.
so what can we do immediately? Make sure that all your devices are up to date, and that means all your devices including routers, TVs, any smart home equipment you might have.
