Attacker Specialization Puts Threat Modeling on Defensive
Specialization among threat groups poses challenges for defenders, who now must distinguish between different actors responsible for different facets of an attack.

Tesla's market share in Europe is collapsing: from 2.8% last February to 1.8% this February, even though EVs are growing. But we need to keep pushing. It needs to be near zero.

Tesla's February market share in Europe drops despite EV pickup

I don't know if all of this is true. I'm not taking it at face value, BUT the concern is real and it's not completely out of the realm of possibilities

You just do not go to the USA at this point, period. At least if you're bold enough to have negative opinions about Trump and his administration (like around 3/4 of all Europeans). It's becoming like a trip to Russia at this point - you can't rule out you'll be jailed in some creepy power play.

I’ve posted a detailed explanation of why the claimed ESP32 Bluetooth chip “backdoor” is not a backdoor. It’s just a poor security practice, which is found in other Bluetooth chips by vendors like Broadcom, Cypress, and Texas Instruments too.

The ESP32 "backdoor" that wasn't | Dark Mentor LLC
4 day class covering the full Bluetooth Low Energy (BLE) protocol stack from the bottom (PHY) up to the top (GATT). The core of the class is built around playing with a game application on an Android phone, talking via Bluetooth to an IoT-type piece of hardware, and analyzing the communication between them. The 4th day is focused on assessing a cutomized Ultra-Vulnerable Peripheral firmware, running on Zephyr RTOS, which has had vulnerabilities introduced into it which are representative of vulnerabilities found in the past across many other platforms.

CJ is an old friend and a longtime cDc NSF member. He suffered a fall and broke his neck -- his insurance refused to pay for an MRI, which led to the break going undiagnosed for a couple of weeks, until his vertebrae had degraded to the point of quadriplegia.
