Researchers drove a NIO ES8 electric SUV deep into a Norwegian underground mine specifically to sever its external connections. The car kept attempting to reach servers, most of them located in China. These findings echo broader concerns about hidden data collection, similar to how a surveillance app was built to covertly target users without their knowledge.
That finding sits at the center of Project Lion Cage, a multi-year study initiated in 2022 by Tor Indstøy, a risk management and threat intelligence executive at Telenor Group. Indstøy purchased the NIO ES8 as a dedicated research platform.
The project arrives as Chinese EV brands expand across European markets with assurances about local data processing. Observed network behavior appears to contradict those assurances.


Why on Earth wouldn’t it keep trying? That’s how signals work. If my router goes down my computer is going to keep trying to connect to it even though it’s off. That’s not fucking news.
Yeah, I had the same thought when reading this
What a weird article
My assumption would be that they drove the car into the mine to see what would (or wouldn’t) work if the vehicle was cut off from the mothership. My hunch is they didn’t really find anything of interest so this is what gets reported.
Also all us cars do the same thing and I would much rather have my data in China than the US.
Thank you!!!
If I’m reading correctly, they specifically tried to stop it from doing so and even in what is essentially a faraday cage it keeps trying to link with Beijing to spill the tea, not exactly what you want if you “own” a product
Yeah, and that’s how connections work.
It doesn’t specify in the article if they toggled the WiFi switch off in the OS, one would assume they did before driving it into a mountain.
If so, not cool to keep calling home. If not, PEBKAC error
