I've flashed firmware plenty of times via WiFi.


I do 5 things before flashing firmware.

• Record or save all settings.
  
• Reset all settings to factory defaults.
  
• Turn the radio off (if WiFi).
  
• Disconnect all Ethernet connections.
  
• Connect one single Ethernet cable, to one single computer.
  

The second time I flashed my BEFSX41, I neglected to remove all Ethernet cables. That was when I had to learn, from a thread in this forum, how to unbrick a BEFSX41.

Maybe I can flash using WiFi. Maybe I can drive down the highway at 80 mph and not get nailed by the cops. Maybe not.

I don't recommend speeding to anybody. Nor will I recommend using WiFi to flash firmware.

Also many routers use Linux so there might be a more trivial way to have the router execute some code.

The only home WiFi routers I am familiar with(Netgear & Linksys) do not let you change code except thru an ethernet linked PC.


Every WiFi router that I've seen lets you flash firmware by connecting to the management server. Using Ethernet or Wifi is equally acceptable to the firmware update process.

I constantly and seriously advise against using WiFi for firmware updates, as it is the best way that I can think of to brick a router. But I don't think that the update process prevents you.

Um, what exactly is taken over, I see the associating with a router part, I dont see the carrier. Is this someone's idea of a semester long project, that they conviently ignore certain real world facts in order to make this hypothetical study?

The only carrier I can think of would be exploiting a linux/firmware security hole, or interfering with TCPIP traffic and injecting something to infect a web browser or similar PC application/
I read the linked PDF on this and there is no mention of how you would infect a router once you can gain access to it. Their whole paper is based on ease of access due to no or weak security. There is nothing on how malware could get on the router once access is attained. The only home WiFi routers I am familiar with(Netgear & Linksys) do not let you change code except thru an ethernet linked PC.
