DEF CON 32

We’re happy to announce that Reverse Everything founder Danilo Erazo presented How I hacked Learning Codes of the key job of a car assembled in my country at DEF CON 32 in 2024

What: How I hacked Learning Codes of the key job of a car assembled in my country
Who: Danilo Erazo
Where: Las Vegas, USA
When: August, 2024

In this presentation, Danilo Erazo shows how it was possible to detect the use of learning codes instead of rolling codes in a key job of a car widely used in Ecuador.

For this purpose, the key job was disassembled and the HS2240 integrated circuit was detected and, using a logic analyzer, the emission of learning codes from the integrated circuit to the radio frequency LED emitter was checked. With the use of HackRF SDR, the learning code is duplicated to be able to open the car N times without needing the original key anymore, which proves that the use of learning codes is very vulnerable, just like fixed codes.
