Researchers have figured how how to intercept and fake an iPhone reboot: We’ll dissect the iOS system and show how it’s possible to alter a shutdown event, tricking a user that got infected into thinking that the phone has been powered off, but in fact, it’s still running. The “NoReboot” approach simulates a real shutdown. … Read More “Faking an iPhone Reboot” »

Apple’s NeuralHash algorithm — the one it’s using for client-side scanning on the iPhone — has been reverse-engineered. Turns out it was already in iOS 14.3, and someone noticed: Early tests show that it can tolerate image resizing and compression, but not cropping or rotations. We also have the first collision: two images that hash … Read More “Apple’s NeuralHash Algorithm Has Been Reverse-Engineered” »

iOS apps are repeatedly reading clipboard data, which can include all sorts of sensitive information.

This is a good explanation of an iOS bug that allowed someone to break out of the application sandbox. A summary: What a crazy bug, and Siguza’s explanation is very cogent. Basically, it comes down to this: XML is terrible. iOS uses XML for Plists, and Plists are used everywhere in iOS (and MacOS). iOS’s … Read More “iOS XML Bug” »

A new iOS exploit allows jailbreaking of pretty much all version of the iPhone. This is a huge deal for Apple, but at least it doesn’t allow someone to remotely hack people’s phones. Some details: I wanted to learn how Checkm8 will shape the iPhone experience­ — particularly as it relates to security­ — so … Read More “New Unpatchable iPhone Exploit Allows Jailbreaking” »

The digital forensics company Cellebrite now claims it can unlock any iPhone. I dithered before blogging this, not wanting to give the company more publicity. But I decided that everyone who wants to know already knows, and that Apple already knows. It’s all of us that need to know. Powered by WPeMatico

This is really just to point out that computer security is really hard: Almost as soon as Apple released iOS 12.1 on Tuesday, a Spanish security researcher discovered a bug that exploits group Facetime calls to give anyone access to an iPhone users’ contact information with no need for a passcode.

Last week, a story was going around explaining how to brute-force an iOS password. Basically, the trick was to plug the phone into an external keyboard and trying every PIN at once: We reported Friday on Hickey’s findings, which claimed to be able to send all combinations of a user’s possible passcode in one go, … Read More “Bypassing Passcodes in iOS” »

Apple is rolling out an iOS security usability feature called Security code AutoFill. The basic idea is that the OS scans incoming SMS messages for security codes and suggests them in AutoFill, so that people can use them without having to memorize or type them. Sounds like a really good idea, but Andreas Gutmann points … Read More “Perverse Vulnerability from Interaction between 2-Factor Authentication and iOS AutoFill” »

apple, cybersecurity, ios, iphone, operatingsystems, Security technology, securityengineering

iOS 12, the next release of Apple’s iPhone operating system, may include features to prevent someone from unlocking your phone without your permission: The feature essentially forces users to unlock the iPhone with the passcode when connecting it to a USB accessory everytime the phone has not been unlocked for one hour.
