Security researchers this week have found a new vulnerability that affects Wi-Fi Protected Access II, also known as WPA2, which is the security protocol used by many wireless networks.

The vulnerability, dubbed “KRACK,” which stands for “Key Reinstallation AttaCK”, allows intruders to breach into WPA2 and steal the data that is being transmitted between a wireless device and a Wi-Fi network, including passwords, messages and photos.

According to the researchers, the vulnerability is also able to inject malware and ransomware into websites and can manipulate data.

WiFi hardware vendors have produced security updates, which companies would do well to follow. To find out whether your hardware vendor is vulnerable, visit the Computer Emergency Readiness Team (US-CERT) website, which lists the at risk hardware vendors and the patches and advisories for companies to follow.
