Although Google’s Android dominates the worldwide smartphone market, the CIA concentrated on Apple’s iOS because of its popularity among global elites, WikiLeaks reports.

The huge trove of leaked CIA documents, codenamed “Vault 7” and released Tuesday by WikiLeaks, reveals that the CIA formed a special unit called the Mobile Development Branch (MDB) to infect smartphones. And within that unit, Apple’s iOS was a prime target.

Apple is in the midst of an all-new controversy, thanks to the mysterious “Error 53” message that is bricking iPhones without warning.

The problem can hit DIY types or anybody who has ever had a Touch ID sensor (or other iPhone hardware) replaced by a repair shop not authorized by Apple. When they update iOS, the device locks down, displaying the cryptic Error 53 message and rendering the iPhone virtually worthless.

Apple says Error 53 is actually a security feature of iOS 9 that keeps your personal information secure, but customers aren’t convinced. Cult of Mac talked to iPhone repair and and parts experts to find out what exactly is going on. The truth is that Error 53 has plagued many iPhone owners, not just those who have replaced Touch ID — and it’s not totally clear why.

Getting a broken home button on your iPhone 6 replaced may cause the entire device to become a worthless brick of metal and glass.

Thanks to a new feature in a software update recently pushed out by Apple, thousands of iPhone users who had their devices fixed by non-official repair shops have been greeted by a disastrous “error 53” message that locks the device — and even the Apple Store can’t bring it back from the dead.

iOS security researchers Jan Souček has discovered a new bug in iOS’s mail client that could trick users into accidentally giving attackers their AppleID and password.

The Mail app exploit was discovered at the beginning of 2015, and Apple’s engineers were quickly notified of its existence, but a fix for the bug hasn’t been released in any of the updates following iOS 8.1.2. According to Souček, the bug allows remote HTML content to be loaded, making it possible to build a password collector that looks just like an iCloud sign-in prompt.

Here’s a video of the bug in action:

Some iPhone users are getting a flashback to 2013 as a new version of the so-called “Unicode of Death” has returned to wreak havoc with their iMessages.

The security exploit, which activates when someone sends you the message in the image above, reportedly forces jailbroken handsets into Safe Mode and completely removes other units’ ability to access the Messages app.
