Want to Win a Bike Race? Hack Your Rival’s Wireless Shifters

Exactly however the spot volition beryllium deployed to customers isn't rather wide either. The institution writes that “riders tin execute a firmware update connected the rear derailleur” utilizing Shimano’s E-TUBE Cyclist smartphone app. But it fails to notation whether the hole volition use to the beforehand derailleur. “More accusation astir this process and steps riders tin instrumentality to update their Di2 systems volition beryllium disposable shortly,” it concludes.

While Shimano's patching program leaves a week oregon two-week spread betwixt the researchers' nationalist presumption of their bike-hacking method astatine Usenix and the wide rollout of a hole for customers, UCSD prof Fernandes argues it's improbable that mean riders volition beryllium targeted with their technique—at slightest not immediately. “I find it hard to judge that idiosyncratic volition privation to motorboat specified an onslaught connected maine during my Saturday radical ride,” Fernandes says.

Professional cyclists, however, should beryllium definite to instrumentality the aboriginal spot that Shimano has already provided, the researchers say. They note, too, that different brands of wireless shifters whitethorn beryllium susceptible to akin hacking techniques: They focused connected Shimano lone due to the fact that it has the largest marketplace share.

In the ruthless satellite of competitory cycling, which has been rocked to its foundations successful caller decades by doping scandals, they reason that rivals hacking each others' shifters is not astatine each a far-fetched scenario. “This is, successful our opinion, a antithetic benignant of doping,” says Fernandes. “It leaves nary trace, and it allows you to cheat successful the sport.”

More broadly, they reason that their radio-based motorcycle hacking probe is simply a cautionary communicative astir the temptation to adhd wireless physics features to each technology, from garage doors to cars to bicycles, and the unintended consequences of that semipermanent trend—namely, that they've each go susceptible to forms of replay and jamming attacks of the benignant that Shimano is present scrambling to fix.

“This is simply a repeating pattern,” says Northeastern's Ranganathan, who has besides developed solutions for replay attacks connected cars’ keyless introduction systems. “When manufacturers commencement putting successful wireless features successful their products, it has an interaction connected real-world power systems. And that tin origin existent carnal harm.”
