Wi-Fi is a pretty central technology to our daily lives, whether at
home or at the office. Given that so much sensitive data is
regularly exchanged between Wi-Fi devices, a number of standards
have been developed to ensure the privacy and authentication of
Wi-Fi communications. However, a recent paper shows that every
single Wi-Fi network protection standard since 1997, from WEP all
the way to WPA3, is exposed to a critical vulnerability that allows
the exfiltration of sensitive data. How far does this new attack
go? How does it work? And why wasn’t it discovered before? We’ll
discuss this and more in this episode of Cryptography FM. Links and
papers discussed in the show: * Fragment and Forge: Breaking Wi-Fi
