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

Meet iOS 11.3: Apple to Make It Harder for Law Enforcement to Extract iPhone Data

Thursday, January 25th, 2018

Forget battery issues. Yes, Apple issued an apology for slowing down the iPhone and promised to add better battery management in future versions of iOS, but that’s not the point in iOS 11.3. Neither are ARKit improvements or AirPlay 2 support. There is something much more important, and it is gong to affect everyone.

Apple iOS is (and always was) the most secure mobile OS. FBI forensic expert called Apple “evil genius” because of that. Full disk encryption (since iOS 4), very reliable factory reset protection, Secure Enclave, convenient two-factor authentication are just a few things to mention. Starting with iOS 8, Apple itself cannot break into the locked iPhone. While in theory they are technically capable of creating (and signing, as they hold the keys) a special firmware image to boot the device, its encryption is not based on a hardware-specific key alone (as was the case for iOS 7 and older, and still the case for most Androids). Instead, the encryption key is also based on the user’s passcode, which is now 6 digits by default. Cracking of the passcode is not possible at all, thanks to Secure Enclave. Still, in come cases, Apple may help law enforcement personnel, and they at least provide some trainings to FBI and local police.

Extracting and Using iCloud Authentication Tokens

Thursday, November 30th, 2017

In our previous blog post, we wrote everything we know about authentication tokens and Anisette data, which might allow you to bypass the “login, password and two-factor authentication” sequence. Let us have a look at how you can actually extract those tokens from a trusted computer and use them on a different computer to access a user’s iCloud account. Read Part 1 and Part 2 of the series.

Extracting Authentication Tokens from a Live System (Windows)

Extracting authentication token from a live system is as easy as running a small, stand-alone executable file you get as part of the Elcomsoft Phone Breaker package. The tool is called ATEX (atex.exe on Windows), and stands for Authentication Token Extractor.

Using the tools is extremely simple. Make sure you are logged on under the user you’re about to extract the token from, and launch ATEX with no arguments. The file named “icloud_token_<timestamp>.txt” will be created in the same folder where you launch the tool from (or C:\Users\<user_name>\AppData\Local\Temp if there are not enough permissions).

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.

Breaking Apple iCloud: Reset Password and Bypass Two-Factor Authentication

Tuesday, November 28th, 2017

Who am I to tell you to use two-factor authentication on all accounts that support it? This recommendation coming from someone whose business is supplying law enforcement with tools helping them do their job might be taken with a grain of salt by an average consumer. Yet we still strongly believe that, however good a password you have to encrypt your local documents or NAS drives, any remotely popular online service absolutely requires an additional authentication factor.

We covered the risks related to passwords more than once. There is no lack of horror stories floating on the Internet, ranging from leaking private photos to suddenly losing access to all data and devices registered on a certain account. Today, smartphones store excessive amounts of information. If any of that data is synced with a cloud, the data will be shared with something other than just your device.

So what is that “other” thing that you need to secure access to your account? It might be something you have in addition to something you know. Something that cannot be easily stolen or accessed remotely. This is exactly what two-factor authentication is for.

All three major mobile companies, Apple, Google and Microsoft, offer very different implementations of two-factor authentication. Speaking Google, you have several convenient options: SMS (which is not really secure, and Google knows it), the recently added Google Prompt, the classic Google Authenticator app, printable backup codes, FIDO keys and a few more. (Spoiler: if you are on a different side and need to extract the data as opposed to protecting it, we have an app for that).

What about Apple? There are a few things you should definitely know about Apple’s implementation. The problem with Apple is that Apple accounts protected with two-factor authentication can be actually less secure at some points. Surprised? Keep reading.

Target: Apple Two-Factor Authentication

Tuesday, November 28th, 2017

Two-factor authentication is essential to secure one’s access to online accounts. We studied multiple implementations of two-factor authentication including those offered by Apple, Google and Microsoft. While Google’s implementation offers the largest number of options, we feel that Apple has the most balanced implementation. The closed ecosystem and the resulting deep integration with the core OS makes it easy for Apple to control exactly how it works and on which devices.

Suppressing the Prompt

Since Apple introduced Two-Factor Authentication (as a replacement of the older and much less secure Two-Step Verification), Apple customers are alerted immediately of someone’s attempt to access their Apple account. A 2FA prompt is pushed instantly and concurrently to all devices the user has in their Apple account once someone attempts to log in. This has always been a hassle for forensic experts trying to perform investigations without alerting the suspect, as merely entering a login and password and seeing a 2FA prompt would mean it’s already too late, as the suspect has been alerted with a prompt.

Or, better to say, it used to be an issue. Just not anymore! Elcomsoft Phone Breaker 8.1, our newest release, now carries out an additional check (which wasn’t exactly easy to make since there is no official API and obviously no documentation), allowing the tool to detect whether or not Two-Factor Authentication is enabled on a given Apple account without triggering a 2FA prompt. The expert will now have the choice of whether to proceed (and potentially alert the suspect) or stop right there.

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…)

Elcomsoft Phone Breaker 8, New Apple Devices and iOS 11

Thursday, September 14th, 2017

With all attention now being on new iPhone devices, it is easy to forget about the new version of iOS. While new iPhone models were mostly secret until announcement, everyone could test iOS 11 for months before the official release.

Out previous article touches the issue of iOS 11 forensic implications. In this article we’ll cover what you can and what you cannot do with an iOS 11 device as a forensic expert. We’ll talk about which acquisition methods still works and which don’t, what you can and cannot extract compared to iOS 10, and what you need to know in order to make the job don’t.

iOS 11: jailbreaking, backups, keychain, iCloud – what’s the deal?

Thursday, September 14th, 2017

iOS 11 is finally here. We already covered some of the issues related to iOS 11 forensics, but that was only part of the story.

Should we expect a jailbreak? Is there still hope for physical acquisition? If not, is logical acquisition affected? Are there any notable changes in iCloud? What would be easier to do: logical or iCloud acquisition, and what are the prerequisites for either method? What do you begin with? How to make sure the suspect does not alter their iCloud storage or wipe their device in the process? Can we actually get more information from the cloud than from the device itself, even with physical, and why?

Spoiler: the short answer to the last question is “yes”. The long answer is a bit complicated. Keep reading.
