A Norwegian student who went wardriving around Oslo on a pushbike has discovered that several popular models of Bluetooth headphones don't implement MAC address randomisation -- meaning they can be used to track their wearers.

More from the article...

...Norwegian state broadcaster NRK revealed Bjorn Hegnes' findings after helping him analyse Bluetooth emissions from a dozen different models of audio headphones, contained within 1.7 million Bluetooth messages he intercepted. Hegnes was collecting the data as part of his first year project at Norof university.

The analysis was possible because Bluetooth devices generally default to broadcasting their unique identities. Yet it appeared that of all the headphones picked up by Hegnes, none of them implemented address randomisation.

Without that randomisation, it was trivial for the devices to be pinged repeatedly, revealing their wearers' precise location as they travelled around the city of Oslo....

I would LOVE to know what popular items were insecure...

I quit using no-name and Chinese owned companies for this type of stuff but I am sure that even big names are dropping the ball.

10 meters is the standard range. A high gain antenna on your scanner will go much further.

I recently watched 'The Conversation' again--a spooky movie with a lot of big stars in it. The setting is the early 1970's. The main character would know things like this, but not publicize it...

Most interesting tid-bit? The cinematographer was fired and replaced - exactly the same as with "One Flew Over The Cuckoo's Nest"

"the original cinematographer of The Conversation was Haskell Wexler. Severe creative and personal differences with Coppola led to Wexler's firing shortly after production began, and Coppola replaced him with Bill Butler. Wexler's footage on The Conversation was completely reshot, except for the technically complex surveillance scene in Union Square.[4] This was the first of two Oscar-nominated films where Wexler would be fired and replaced by Butler, the second being One Flew Over the Cuckoo's Nest (1975), where Wexler had similar problems with Milo Forman.[5]"

Another reason I dont use bluetooth when I dont have to. I dont use wireless keyboards or anything else that's wireless.The only thing that's bluetooth in my house is my phones to my wireless router. Everything else is wired down to the Peloton.
