Update Windows (and Lots of Other Stuff) ASAP: 'FragAttack' Bugs Found Lurking in Millions of Wifi Devices - Gizmodo

A slew of new wifi vulnerabilities impact everything from cellphones and routers to, well, anything wifi-connected, according to a new report by a Belgian cybersecurity expert.

Mathy Vanhoef—who you might know for co-discovering the widespread wifi KRACK attack back in 2017—dubbed this new collection of vulnerabilities “fragmentation and aggregation attacks,” or FragAttacks for short.

Per Vanhoef’s explanation on the dedicated FragAttacks site he set up, nine of these flaws stem from programming hiccups in specific wifi products, and the other three are due to-baked in bugs in the wifi standard itself—even the security protocol some wifi networks use, called WEP, is impacted.
