Wearable Botnets and Happy Hacked Drivers
summary
A hands-on security talk demonstrating hardware and firmware attacks: the presenter removes a dishwasher PCB, identifies an NEC R8C MCU, dumps its flash with a reader and uses JTAG/serial and logic probes to reverse firmware, finding trivial buffer overflows and static C libraries that ease exploitation. The talk also shows finding an Arduino with default arduino/arduino credentials in a home PV gateway, gaining network access via DHCP, exploiting uConnect-open ports and Sprint 3G to enumerate ~2,695 reachable cars, installing modified firmware to inject CAN messages that reproduce steering and brake manipulation, and estimating a botnet potential on the order of hundreds of Gbps.
