FragAttacks: The Wi-Fi Flaws Hiding in Almost Every Device

FragAttacks are twelve Wi-Fi vulnerabilities disclosed in 2021, three of which are design flaws in the Wi-Fi standard dating to 1997.

What FragAttacks Actually Are

Which Devices Are Affected

Because the design flaws are in Wi-Fi itself, the affected list is essentially "anything with Wi-Fi." The implementation bugs vary by manufacturer and firmware version.

How To Protect Yourself

The good news is that defense is mostly about hygiene you should be doing anyway.
