Researchers from UC San Diego and Northeastern University expose vulnerabilities in Shimano wireless gear-shifting systems, enabling potential sabotage in professional cycling.
As cycling gear evolves into cyber-physical systems, vulnerabilities can be exploited easily. Unauthorized signals can shift gears or disable shifters from a distance.
"Imagine you're going uphill on a Tour de France stage: If someone shifts your bike from an easy gear to a hard one, you're going to lose time," says Earlence Fernandes.
The very nature of competitive cycling is at risk as wireless technology is hacked, posing severe consequences to both fairness and safety in races.
