Vulnerability in Wi-Fi Protocol Threatens Traffic from Any Device


Wi-Fi Protected Access II Wi-Fi (Wi-Fi Protected Access II), used by many users to connect to the Internet, revealed vulnerabilities that allow hackers to intercept Wi-Fi traffic. The exploit called KRACK was dangerous not only for computers, but also for mobile devices, including the iPhone and iPad.

The bottom line is that the traffic encryption key is created using the "four-way handshake" protocol WPA2, and in the third step the key can be redirected and completely undermine the encryption of traffic. As Ars Technica writes with reference to experts from the US-CERT organization, hackers similarly can intercept information that is transmitted to users' devices via Wi-Fi.

In the near future, experts say, some of the routers will receive an update that will protect users from intruders. True, many private and public Wi-Fi routers will still remain vulnerable to hackers until they are patched. So check the software for your router just in case.

In the meantime, experts recommend using HTTPS, STARTTLS, Secure Shell and other reliable protocols for encrypting traffic on the Internet and e-mail.
