How To Access Screen Time Password and Recover iOS Restrictions Password

Thursday, August 29th, 2019

The Screen Time passcode (known as the Restrictions passcode in previous versions of iOS) is a separate 4-digit passcode designed to secure changes to the device settings and the user’s Apple ID account and to enforce the Content & Privacy Restrictions. You can add the Screen Time passcode when activating Screen Time on a child’s device or if you want to add an extra layer of security to your own device.

The 4-digit Screen Time passcode is separate to the main screen lock passcode you are using to unlock your device. If you configure Screen Time restrictions to your usage scenarios, you’ll hardly ever need to type the Screen Time password on your device.

Using the Screen Time password can be a great idea if you want to ensure that no one can reset your iTunes backup password, disable Find My iPhone or change your Apple ID password even if they steal your device *and* know your device passcode. On a flip side, there is no official way to recover the Screen Time password if you ever forget it other than resetting the device and setting it up from scratch. Compared to the device screen lock passcode, Screen Time passwords are much easier to forget since you rarely need it.

In this article, we’ll show you how to reveal your iOS 12 Screen Time passcode (or the Restrictions passcode if you’re using iOS 7 through 11) using Elcomsoft Phone Viewer. (more…)

iOS 13 (Beta) Forensics

Thursday, July 25th, 2019

iOS 13 is on the way. While the new mobile OS is still in beta, so far we have not discovered many revolutionary changes in the security department. At the same time, there are quite a few things forensic specialists will need to know about the new iteration of Apple’s mobile operating system. In this article, we’ll be discussing the changes and their meaning for the mobile forensics.

iCloud backups

We’ve seen several changes to iCloud backups that break third-party tools not designed with iOS 13 in mind. Rest assured we’ve updated our tools to support iOS 13 iCloud backups already. We don’t expect the backup format to change once iOS 13 is officially released, yet we keep an eye on them.

First, Apple has changed the protocol and encryption. There’s nothing major, but those changes were more than enough to effectively block all third-party tools without explicit support for iOS 13.

Second, cloud backups (at least in the current beta) now contain pretty much the same set of info as unencrypted local backups. Particularly missing from iCloud backups made with iOS 13 devices are call logs and Safari history. This information is now stored exclusively as “synchronized data”, which makes it even more important for the investigator to extract synced evidence in addition to backups. Interestingly, nothing was changed about synced data; you can still use the same tools and sign in with either Apple ID/password/2FA or authentication tokens. (more…)

Apple iTunes: Standalone vs. Microsoft Store Edition

Wednesday, January 23rd, 2019

Since April 2018, Apple made iTunes available to Windows 10 users through the Microsoft Store. While the stand-alone download remains available from Apple’s Web site, it is no longer offered by default to Windows 10 users. Instead, visitors are directed to Microsoft Store, which will handle the installation and updates of the iTunes app.

The iOS File System: TAR and Aggregated Locations Analysis

Thursday, June 7th, 2018

Finally, TAR support is there! Using Elcomsoft iOS Forensic Toolkit to pull TAR images out of jailbroken iOS devices? You’ll no longer be left on your own with the resulting TAR file! Elcomsoft Phone Viewer 3.70 can now open the TAR images obtained with Elcomsoft iOS Forensic Toolkit or GrayKey and help you analyse evidence in that file. In addition, we added an aggregated view for location data extracted from multiple sources – such as the system logs or geotags found in media files.

What Are These TAR Files Anyway?

While TAR is just an uncompressed file archive used in UNIX-based operating systems, this speaks little of its importance for the mobile forensic specialist.

Since the introduction of the iPhone 5s, Apple’s first 64-bit iPhone, physical acquisition has never been the same. For all iPhone and iPad devices equipped with Apple’s 64-bit processors, physical acquisition is exclusively available via file system extraction because of full-disk encryption. Even with a jailbreak, you must run the tarball command on the device itself in order to bypass the encryption. Since the file system image is captured and packed by iOS, you’ll get exactly the same TAR file regardless of the tool performing physical acquisition. Whether you use iOS Forensic Toolkit or GrayKey, you’ll receive exactly the same TAR archive containing an image of the device’s file system. (more…)

Apple iCloud Keeps More Real-Time Data Than You Can Imagine

Thursday, February 8th, 2018

Apple has a wonderfully integrated ecosystem. Apple computers, tablets and phones conveniently synchronize information such as passwords, Web browsing history, contacts and call logs across all of the user’s devices. This synchronization mechanism uses iCloud to sync and store information. The syncing mechanism works independently from iOS system backups that are also stored in iCloud (or iCloud Drive). As opposed to daily iCloud backups, synchronized data is updated and propagated across devices in almost real time. Extracting this information can be invaluable for investigations as it provides access to the most up to date information about the user, their activities and whereabouts.

What exactly is synced through iCloud? The screen shot above lists all options available in iOS 11. As you can see, the following types of data are (or can be) synced across Apple devices:

  • Photos (iCloud Photo Library)
  • Mail (iCloud mail only)
  • Contacts, Calendars and Reminders
  • Safari (browsing history, bookmarks and tabs open on other devices)
  • Game Center (profiles, achievements and game progress)
  • Siri (requests, settings)
  • Keychain (iCloud Keychain stores passwords and forms from Safari, iOS system, Apple and some third-party apps, but not Google Chrome)
  • iCloud backups (up to last 3 copies per device, created daily while charging)
  • iBooks, Pages, Numbers and Keynote (e-books, PDF files, documents)
  • Maps (user’s search history, routes and places)
  • Wallet
  • Wi-Fi

iOS 11 Horror Story: the Rise and Fall of iOS Security

Wednesday, November 29th, 2017

We loved what Apple used to do about security. During the past years, the company managed to build a complete, multi-layer system to secure its hardware and software ecosystem and protect its customers against common threats. Granted, the system was not without its flaws (most notably, the obligatory use of a trusted phone number – think SS7 vulnerability – for the purpose of two-factor authentication), but overall it was still the most secure mobile ecosystem on the market.

Not anymore. The release of iOS 11, which we praised in the past for the new S.O.S. mode and the requirement to enter a passcode in order to establish trust with a new computer, also made a number of other changes under the hood that we have recently discovered. Each and every one of these changes was aimed at making the user’s life easier (as in “more convenience”), and each came with a small trade off in security. Combined together, these seemingly small changes made devastating synergy, effectively stripping each and every protection layer off the previously secure system. Today, only one thing is protecting your data, your iOS device and all other Apple devices you have registered on your Apple account.

The passcode. This is all that’s left of iOS security in iOS 11. If the attacker has your iPhone and your passcode is compromised, you lose your data; your passwords to third-party online accounts; your Apple ID password (and obviously the second authentication factor is not a problem). Finally, you lose access to all other Apple devices that are registered with your Apple ID; they can be wiped or locked remotely. All that, and more, just because of one passcode and stripped-down security in iOS 11.

Obtaining Detailed Information about iOS Installed Apps

Tuesday, October 3rd, 2017

Accessing the list of apps installed on an iOS device can give valuable insight into which apps the user had, which social networks they use, and which messaging tools they communicate with. While manually reviewing the apps by examining the device itself is possible by scrolling a potentially long list, we offer a better option. Elcomsoft Phone Viewer can not just display the list of apps installed on a given device, but provide information about the app’s version, date and time of acquisition (first download for free apps and date and time of purchase for paid apps), as well as the Apple ID that was used to acquire the app. While some of that data is part of iOS system backups, data on app’s acquisition time must be obtained separately by making a request to Apple servers. Elcomsoft Phone Viewer automates such requests, seamlessly displaying the most comprehensive information about the apps obtained from multiple sources.

In this how-to guide, we’ll cover the steps required to access the list of apps installed on an iOS device. (more…)

Accessing iOS Saved Wi-Fi Networks and Hotspot Passwords

Thursday, September 28th, 2017

In this how-to guide, we’ll cover the steps required to access the list of saved wireless networks along with their passwords.

Step 1: Make a password-protected backup

In order to extract the list of Wi-Fi networks from an iOS device, you must first create a password-protected local backup of the iOS device (iPhone, iPad or iPod Touch). While we recommend using Elcomsoft iOS Forensic Toolkit for making the backup (use the “B – Backup” option in the main menu), Apple iTunes can be also used to make the backup. Make sure to configure a backup password if one is not enabled; otherwise you will be unable to access Wi-Fi passwords. (more…)

Extracting Unread Notifications from iOS Backups

Thursday, March 2nd, 2017

In the world of no jailbreak, acquisition opportunities are limited. Experts are struggling to access more information from those sources that are still available. Every little bit counts. In Elcomsoft Phone Viewer 3.0, we’ve added what might appear like a small bit: the ability to view undismissed iOS notifications. Unexciting? Hardly. Read along to discover how extracting notifications from iOS backups can make all the difference in an investigation! (more…)

Extracting Calls, Contacts, Calendars and Web Browsing Activities from iOS Devices in Real Time

Wednesday, December 21st, 2016

Cloud acquisition has been available for several years. iPhones and iPads running recent versions of iOS can store snapshots of their data in the cloud. Cloud backups are created automatically on a daily basis provided that the device is charging while connected to a known Wi-Fi network. While iCloud backups are great for investigations, there is one thing that might be missing, and that’s up-to-date information about user activities that occurred after the moment the backup was created. In this article, we’ll discuss an alternative cloud acquisition option available for iOS devices and compare it to the more traditional acquisition of iCloud backups.
