David Buchanan highlights the controversy surrounding the Rabbit R1, claiming it “sucks” and the company may be deceiving customers. He outlines his journey to develop a “tethered jailbreak” for the R1, delving into the boot process and subverting it without compromising internal storage. Despite difficulties with obfuscated code and anti-analysis measures, he successfully gains root access. Buchanan reveals Rabbit Inc.’s violation of the GPL2 license by keeping closed-source drivers in their kernel image. Through his detailed explanation and innovative approach, he creates a “bootkit” named “carroot” that grants root access to the Rabbit R1 without altering system properties.
