A hacker has formulated an exploit that provides root access to two popular models of the company's farm equipment.
that manufacturers impose on their vehicles. Like insulin pump “looping” and iPhone jailbreaking, this allows farmers to modify and repair the expensive equipment that’s vital to their work, the way they could with analog tractors. At the DefCon security conference in Las Vegas on Saturday, the hacker known as Sick Codes is presenting a new jailbreak for John Deere & Co tractors that allows him to take control of multiple models through their touchscreens.
The finding underscores the security implications of right-to-repair. The tractor exploitation that Sick Codes uncovered isn't a remote attack, but the vulnerabilities involved represent fundamental insecurities in the devices that could be exploited by malicious actors or potentially chained with other vulnerabilities.
have shown. At the same time, though, vulnerabilities like the ones that Sick Codes found help farmers do what they need to do with their own equipment.Sick Codes, an Australian who lives in Asia,in 2021 about tractor application programming interfaces and operating system bugs. After he made his research public, tractor companies, including John Deere, started fixing some of the flaws. “The right-to-repair side was a little bit opposed to what I was trying to do,” he tells WIRED.
This year, Sick Codes says that while he is primarily concerned about world food security and the exposure that comes from vulnerable farming equipment, he also sees important value in letting farmers fully control their own equipment. “Liberate the tractors!” he says. After years of controversy in the US over the “right to repair” the equipment one purchases, the movement seems to have reached a turning point. The White House issued an
