CTS 210: TWIW – Kr00k, CLI Mapping, YouTube, FCC, & DevNet

Welcome to another episode of This Week in Wireless (TWiW) where we discuss recent news in the wireless industry.



Kr00k



Products affected: (Broadcom and Cypress Chips)



* Aruba* 200 series* 344 & 345* 504 & 505* 514 & 515* Cisco* C9115* C9120

802.11w can help in this scenario as it would protect management frames.



Some major vendors have published their patches for the bug, including Cisco and Aruba.

FCC Proposes Fines for Carriers Selling Location Data… insecurely?

Quite the interesting take and it’s great that the FCC supports the selling of our location data. No biggie.



The fines are enormous but nothing but a drop in the bucket for these companies.
