Security vulnerability in CocoaPods dev tool could have affected millions of iOS apps

Second teen who hacked into Apple servers gets probation

The security of millions of iOS apps could have been compromised due to a security vulnerability in the popular dependency manager CocoaPods.

Software developers often rely on code written by other companies or developers in order to speed up the development of their products. To facilitate the management of code from other sources — known as dependencies — developers use a tool called a dependency manager. The same is true when developing for Apple’s platforms, and the most popular dependency manager for iOS apps by far is CocoaPods.

This past Monday, the maintainers of the project released a statement uncovering a security issue that’s been recently discovered and was present in the software since June 2015, giving attackers plenty of time to potentially exploit it.

Apple officially unveils AirTag item tracker

During its Spring Loaded event, Apple has finally unveiled the long-rumored and profusely leaked AirTag, its item tracker integrated into the Find My network. We’ve known about this product since early 2019, when 9to5Mac reported about its development. Since then, the product has made several appearances in iOS builds and even appeared briefly in a YouTube video on Apple’s Support channel.

Tired of waiting for Apple’s AirTags? This open-source project lets you create your own

The first report about Apple working on an item tracker was back in April 2019, here on 9to5Mac. Since then, we’ve seen the device appear and disappear from iOS builds and even show up in an official Apple video on YouTube. More recently, rumors started picking up again about its imminent release, given the presence of support for third-party item trackers in iOS 14.5, which will also work for Apple’s own item tracking device.

But if you’re tired of waiting for Apple to release their own item tracker, there’s an open-source project that might help you, but only if you’re into hacking. Researchers from German university TU Darmstadt reverse-engineered the protocol used by Apple devices to participate in the Find My network and released free resources for those who would like to create their own item-tracking device at home.
