Sideloading is a malware danger, Apple tells U.S. lawmakers

Apple has written to the U.S. Senate Judiciary Committee to dispute claims made by an expect about sideloading, insisting its arguments about the technique being a malware vector are justified.

In February, the Senate Judiciary Committee voted to advance forward the Open Markets Act in February, legislation that could force Apple to allow the sideloading of apps. In a continued effort to fight the measure, Apple has written to lawmakers about malware dangers.

The letter, sent on Thursday and seen by Reuters, talks about comments from computer security expert Bruce Schneider, where he says Apple's concerns about sideloading are "unfounded."

In response, Apple argued that sideloading is beneficial to malware producers, as it relies on users being tricked to download it rather than requiring hackers to more directly break device security. The App Store review process "creates a high barrier against the most common scams used to distribute malware," writes Apple.

Though Apple does accept Schneider's comments that state-sponsored hackers have the potential to break device security directly, such attacks are a "rare threat" to consumers. "There is ample evidence showing third-party app stores are a key malware vector on platforms which support such stores," urges the iPhone maker.

Apple's letter was sent to Dick Durbin, the Senate Judiciary Committee chair, as well as its top Republican, Chuck Grassley. It was also sent to antitrust subcommittee chair Amy Klobuchar and its top Republican, Mike Lee.

In a previous letter to top Senate lawmakers on February 3, Apple said the Open Markets Act would harm user security and privacy. Sideloading "would enable bad actors to evade Apple's privacy and security protections by distributing apps without critical privacy and security checks."

The Open Markets Act is an antitrust bill that applies restrictions to Apple, Google, and other platform holders. It would ban policies preventing sideloading, as well as essentially forcing the acceptance of third-party payment systems, among other measures.

Of course side loading is a malware danger. That was never being debated. The solution is simple: A switch that turns on side loading and turns off features like the official Apple App Store and iCloud that would be compromised by a side loaded app. Users who enable side loading would use third party app stores on their device. It's perfect for older iOS devices that otherwise would otherwise collect dust and is also a great way to recycle old devices. I bet less than 10% of iOS users would enable side loading on an old device but if they want to they should be able to. This is why jailbreaking exists. Apple should just make an official way to jailbreak old devices and be done with it.

Apple should allow jailbreaking by letting users replace iOS with Android, but not by weakening iOS.

You are neglecting the fact that should side loading be allowed on iOS, companies like FaceBook would insist that any software developers who want data from FaceBook would be required to make their app "require side loading." That way FaceBook gets more data. And with a majority of software switching to side-loading to become more profitable, everything would have to be side loaded.

FaceBook could not require that users enable side loading in order to use their app. The market size is just too small. I would expect very few iOS users to enable side loading and disable iCloud an App Store apps on their devices. FaceBook can't give up the iOS market and they don't have the weight to force users to do anything. FaceBook still works in a browser so users would simply stop using the FaceBook app if they tried it.

Allowing jailbreaking does not weaken iOS. It strengthens it. Currently jail breaking is possible in older versions of iOS. That's really bad for security because it means that apps the user downloads from the official App Store on those devices have their personal data exposed to other apps. With the method I propose, it means that side loaded apps would not have access to any secure information. Users would have to manage security on their own (or with third party apps). A jail broken iPhone would be exactly like a Mac Book, Windows PC or Raspberry Pi when it comes to security.

I don't like the security argument, because if iOS sandboxing would work flawlessly, sideloading would not be a problem.
On the other side, the App Store review process was never good in preventing malware, more in being compliant with Apple's rules.

So I would like to see:

- iOS (and sandboxing) being more robust
- Sideloading being allowed, but with developer certificate (like on the Mac), so that bad apps can be wiped remotely by revoking the certificate
- 3rd party app store, that have their own review process and their own set of compliance rules

All in all I strongly believe this would help Apple to grow the platform and not be harmful at all!

Apple is not wrong. 

But I guess congress and the lobby groups are going to have to find out the hard way. Trouble is that so many developers will just jump ship and insist their app must be side loaded, to keep the 30% cut, that we all are going to end up side loading something.
It’s not going to be pretty.
I predict though that Apple will be who gets sued when people side load something that steals their data.
