01What happened
The story, straight
YouTuber Mark Rober revealed in his latest video that he used a homemade relay attack device to steal a car from Twitch streamer JasonTheWeen while he was live on stream. The device, which intercepts the signal between a car and its key fob, was reverse-engineered from parts of a 2004 video baby monitor, bringing the cost from $12,000 on the black market down to roughly $100. Rober and CrunchLabs employee Ian snuck into Jason's driveway at the former FaZe house, where security cameras captured them approaching the 2026 Hyundai Sonata giveaway car and driving it away in seconds.
mark rober snuck into jasontheween's driveway at the faze house while he was live on stream and drove off with his brand new 2026 hyundai sonata giveaway car. the whole thing was a demo of keyless entry relay attack theft — rober built a device from a 2004 baby monitor that copies the car key's signal. the black market version costs $12,000; his homemade one costs about $100. security cameras caught him and crunchlabs coworker ian pulling up to the driveway and leaving with the car in seconds.

What's solid and what isn't
- Mark Rober built a homemade relay attack device from a 2004 video baby monitor for roughly $100.
- Rober stole JasonTheWeen's 2026 Hyundai Sonata giveaway car from the former FaZe house driveway while Jason was streaming on Twitch.
- Security cameras captured Rober and CrunchLabs employee Ian approaching and taking the car.
- Rober originally purchased a $12,000 relay attack device from a black market dealer named Dimitri before reverse-engineering it.
05Why it matters
The editorial take
The stunt doubles as a genuine cybersecurity demonstration: relay attack devices are a real and growing vector for keyless entry car theft. Rober, who has 46 million YouTube subscribers and a track record of viral engineering projects, turning this into content with a major streamer gives the issue massive visibility. JasonTheWeen's audience skews young — exactly the demographic most likely to own newer cars with keyless entry and least likely to know about this vulnerability.
this is rober doing what he does best — making a real security threat go viral by staging it as spectacle. relay attacks are a genuine problem for any car with keyless entry and most people have zero idea they exist. dropping a $100 proof-of-concept with a streamer who hits the exact demo that needs to hear this is smart engineering content.
