Task: HackTheBox hardware challenge with a Saleae .logicdata CAN capture and a socket.io bridge to a live car. Solution: reverse the .logicdata as uint16 analog samples, decode single-wire CAN at 1.25 Mbps (invert + destuff + CRC-15) to learn the frame format, then connect via an Engine.IO v3 client and flood spoofed 0x122 (lock:1) and 0x402 (speed=0) frames to stop the car and lock the doors.
