Police in Luxembourg reported a vehicle stolen on 24 July despite the key being left inside the home. Investigators said thieves captured and relayed the key’s radio signal to unlock and start the car, a technique known as a relay attack. Authorities warned owners of keyless‑go systems to keep cars in closed garages, use alarm systems, store keys in RF‑blocking cases and watch for suspicious devices near the vehicle.
Separately, researchers at the University of California, San Diego disclosed a critical Bluetooth‑based relay vulnerability in Acrisure Protection Group’s KARR anti‑theft system. The flaw, affecting an estimated 2.2 million vehicles, was reported in January 2025 but a software patch was only released on 20 July, leaving many owners unprotected. A similar flaw had previously been found in Subaru’s Starlink system and quickly fixed. Acrisure notes that only paying customers who have installed the KARR app can apply the update, leaving roughly half of the affected users exposed. In France, more than 140 000 vehicles are reported stolen each year, often through organized networks exploiting keyless systems.
