A Belgian researcher discovered a vulnerability in the WPA2 security protocol used with a wireless Wi-Fi connection, according to the website of the scientist Krackattacks. Security expert from the Catholic University of Leuven, Mathy Vanhoef, argues that “any device that supports Wi-Fi can be exposed (hacking).”
“Hackers can apply this new technique to read information that, as previously thought, is securely encrypted,” the researcher reports. According to him, hackers can get credit card numbers, passwords, messages from chat rooms, emails, photos and other data.
“It is possible to attack any modern, protected Wi-Fi network, depending on the network configuration, it is possible to make new data and operate on them. For example, a hacker can infect a website with a virus-extortionist,” Vanhoff says.
According to the expert, there are vulnerabilities in many operating systems and devices, including Android, Linux, Apple, Windows, OpenBSD, MediaTek, Linksys and others.
Vanhof says that the vulnerability can be eliminated. He also notes that changing the password on a Wi-Fi connection will not save the user from a hacker attack.
