Security researchers have found a devastating flaw in WPA2 WiFi encryption protocol that makes it possible for hackers to intercept your sensitive information. This vulnerability named KRACK (Key Reinstallation Attack) affects Wi-Fi protocol and not a specific product or impentation. An attacker within range of a victim can exploit these weaknesses.
KRACK targets the third step in a four-way authentication “handshake” performed when a WI-FI client attempts to connect to a protected network. This can lead to stealing of information by the attackers including your credit card and confidential data.
To protect against this flaw, major OSes and routers are working round the clock to provide a patch. Apply the patch as soon as possible. Meanwhile, do not share any personal or confidential information on a non secure website and only use secure or HTTPS sites.
Also avoid using free hotspots or use a secure VPN or connection like GajShield Enterprise Cloud, if you must use a Wifi network.
Our research team is working in our labs to gain more information about the latest KRACK attacks and will keep you updated on future course of action. Until then keep a close tab on any latest updates or patches released for your affected products and apply them as soon as possible
