Computer scientists at the University of California San Diego and Northeastern University have found that Shimano Di2 wireless tweaks can be hacked, posing serious risks in competitive cycling.
The researchers identified vulnerabilities in Shimano’s wireless systems that could have dire consequences for rider safety and performance, especially during professional races where jams or shifts could lead to crashes.
They discovered three major vulnerabilities including lack of mechanisms to prevent replay attacks, susceptibility to targeted jamming, and information leakage through ANT+ communication.
This highlights the need for improved security measures in wireless gear-shifting systems, especially since these vulnerabilities could be exploited to gain unfair advantages in events like the Tour de France.
