 i chips\n   When: Sunday\, Aug 13\, 11:00 - 11:45 PDT\n   Where: Caesars F
 orum - Forum - 130-134 - Track 3 - [1]Map\n\n   SpeakerBio:Daniel Wegemer 
 \, Hacker\n   Security Researcher interested in enabling new features in c
 losed\n   source firmware. Areas of interest are: Wifi\, IoT and Automotiv
 e.\n\n   Description:\n   Wifi chips contain general purpose processors. E
 ven though these are\n   powerful processors\, their firmware is closed so
 urce and does not\n   allow modifications. This talk explores how the firm
 ware of modern\n   Xtensa based Qualcomm Wifi chips can be modified to all
 ow extending\n   its indented functionality. Such modifications can even b
 e for example\n   leveraged by security researchers to find vulnerabilitie
 s in an\n   otherwise closed source Wifi code. During the talk we will als
 o dive\n   into the architecture of Qualcomms Wifi chips as well as the st
 ructure\n   of the firmware used withing these chips. We will release a mo
 dified\n   version of the Nexmon framework to enable patching of Xtensa ba
 sed\n   firmware and show all the steps involved to create such patches.\n
