Yesterday, Gizmodo reported that Uber had been granted an entitlement for their iOS app that allowed them to capture an image of an iPhone’s screen at any time, even when the Uber app was not the active app on the phone. This is a big deal, because users don’t typically expect than an iPhone app that is not active might have the ability to eavesdrop on anything they are doing.
I have long felt that the sandboxing infrastructure on both iOS and Mac should be used to more accurately convey to users specifically what the apps they install are capable of doing. Currently the sandboxing system is used primarily to identify to Apple what a specific app’s privileges are. The requested entitlements are used to inform Apple’s decision to approve or reject an app, but the specific list of entitlements is not easily available to users, whose security is actually on the line.
This is absolutely fucking ridiculous. Fuck Uber. Apple should be ashamed for working with them at any level. Allowing an app to covertly record your screen without any prompting is exactly the kind of thing that Apple’s iOS app review process should prevent.
Uber claims they didn’t do anything wrong with this ability, the security researchers told Gizmodo that they didn’t detect anything going on with this code.
There are companies that are less trustworthy than Uber, but few have the opportunity to be as evil on such a large scale. Enabling them to do anything more than operate at a basic level on your platform is a mistake. At this point Apple should block them entirely and attempt to help the Taxi industry to reform and compete with Uber. Not that Apple would ever would, but still that would be the best thing to come out of this. The next best thing would be the improvements to the entitlement system that Jalkut suggests.
I wouldn’t even bother to wonder what Uber are doing on Android, where security is a fucking joke and carriers are still selling devices running ancient versions of that operating system that are affected by dozens of security vulnerabilities. This is especially true for pay-as-you-go phones sold cheaply at places like Walmart, Target, and so on. Those carriers and stores are endangering their customers by continuing to sell these devices.
