Extract and Decrypt WhatsApp Backups from iCloud

Thursday, July 20th, 2017

Facebook-owned WhatsApp is the most popular instant messaging tool worldwide. Due to its point-to-point encryption, WhatsApp is an extremely tough target to extract.

As we already wrote in yesterday’s article, WhatsApp decryption is essential for the law enforcement since due to its popularity and extremely tough security it is a common choice among the criminals. However, the need for WhatsApp decryption is not limited to law enforcement. Us mere mortals may need access to our own communications when re-installing WhatsApp, changing devices or extracting conversations occurred on a device we no longer possess. Since WhatsApp data is not always available in iOS system backups, using WhatsApp’ own stand-alone cloud backup system is the more reliable choice compared to pretty much everything else.

Elcomsoft Explorer for WhatsApp can now access iPhone users’ encrypted WhatsApp communication histories stored in Apple iCloud Drive. If you have access to the user’s SIM card with a verified phone number, you can now use Elcomsoft Explorer for WhatsApp to circumvent the encryption and gain access to iCloud-stored encrypted messages. In this article, we’ll tell you how it works, and provide a step-by-step guide to extracting and decrypting WhatsApp backups from iCloud Drive.

iCloud Outage, New Token Expiration Rules and Fixes for Authentication Issues

Tuesday, July 11th, 2017

In early July, 2017, Apple has once again revised security measures safeguarding iCloud backups. This time around, the company has altered the lifespan of iCloud authentication tokens, making them just as short-lived as they used to be immediately after celebgate attacks. How this affects your ability to access iCloud data, which rules apply to iCloud tokens, for how long you can still use the tokens and how this affected regular users will be the topic of this article.

The New Google Authentication Engine in Elcomsoft Cloud Explorer 1.31

Thursday, June 15th, 2017

As you may know, we have recently updated Elcomsoft Cloud Explorer, bumping the version number from 1.30 to 1.31. A very minor update? A bunch of unnamed bug fixes and performance improvements? Not really. Under the hood, the new release has major changes that will greatly affect usage experience. What exactly has changed and why, and what are the forensic implications of these changes? Bear with us to find out.

Android Encryption Demystified

Tuesday, May 23rd, 2017

How many Android handsets are encrypted, and how much protection does Android encryption actually provide? With Android Nougat accounting for roughly 7% of the market, the chance of not being adequately protected is still high for an average Android user.

Android Central published an article titled More Android phones are using encryption and lock screen security than ever before. The author, Andrew Martonik, says: “For devices running Android Nougat, roughly 80% of users are running them fully encrypted. At the same time, about 70% of Nougat devices are using a secure lock screen of some form.”

This information is available directly from Google who shared some security metrics at Google I/O 2017.

“That 80% encryption number isn’t amazingly surprising when you remember that Nougat has full-device encryption turned on by default”, continues Andrew Martonik, “but that number also includes devices that were upgraded from Marshmallow, which didn’t have default encryption. Devices running on Marshmallow have a device encryption rate of just 25%, though, so this is a massive improvement. And the best part about Google’s insistence on default encryption is that eventually older devices will be replaced by those running Nougat or later out of the box, meaning this encryption rate could get very close to 100%.”

So how many Android handsets out there are actually encrypted? Assuming that 0.25 (25%) of Android 6 handsets use encryption, and 0.8 (80%) of Android 7 phones are encrypted, it will be possible to calculate the number of encrypted handsets out of the total number of Android devices.

Let’s have a look at the current Android version distribution chart:

  • Android 5.1.1 and earlier versions: ~62% market share
  • Android 6: 31 (31% market share) * 0.25 = 0.078
  • Android 7: 0.07 (7% market share) * 0.80 = 0.056

We Did It Again: Deleted Notes Extracted from iCloud

Friday, May 19th, 2017

As we already know, Apple syncs many types of data across devices that share the same Apple ID. Calls logs, contacts, Safari tabs and browsing history, favorites and notes can be synced. The syncing mechanism supposedly synchronizes newly created, edited and deleted items. These synchronizations work near instantly with little or no delay.

Apple is also known for keeping some items that users want to be deleted. As a reminder, this is a brief history of our findings:

What’s It All About?

Apple has a great note taking app that comes pre-installed on phones, tablets and computers. The Notes app offers the ability to take notes and sync them with the cloud to other devices using the same Apple ID. We discovered that Apple apparently retains in the cloud copies of the users’ notes that were deleted by the user. Granted, deleted notes can be accessed on iCloud.com for some 30 days through the “Recently Deleted” folder; this is not it. We discovered that deleted notes are actually left in the cloud way past the 30-day period, even if they no longer appear in the “Recently Deleted” folder.

For accessing those notes, we updated Elcomsoft Phone Breaker to version 6.50. (more…)

ElcomSoft vs. The Cloud: a Game of Cat and Mouse

Friday, May 12th, 2017

We’ve got a few forensic tools for getting data off the cloud, with Apple iCloud and Google Account being the biggest two. Every once in a while, the cloud owners (Google and Apple) make changes to their protocols or authentication mechanisms, or employ additional security measures to prevent third-party access to user accounts. Every time this happens, we try to push a hotfix as soon as possible, sometimes in just a day or two. In this article, we’ll try to address our customers’ major concerns, give detailed explanations on what’s going on with cloud access, and provide our predictions on what could happen in the future.

Update 19/05/2017: what we predicted has just happened. Apple has implemented additional checks just two days ago. This time, the extra checks do not occur during the authentication stage. Instead, the company started blocking pull requests for backup data originating from what appears to Apple as a desktop device (as opposed to being an actual iPhone or iPad). Once again we had to rush a hotfix to our customers, releasing an update just today. Whether or not our solution stands the test of time is hard to tell at this time. It seems this time it’s no longer a game but a war.

This whole Apple blocking third-party clients issue creates numerous problems to our customers who are either legitimate Apple users or law enforcement officials who must have access to critical evidence now as opposed to maybe getting it from Apple in one or two weeks. This time it’s not about security or privacy of Apple customers. After all, accounts protected with two-factor authentication are and have been safe. We’ve had similar experience with Adobe several years ago, and surprisingly, it turned out Adobe had reasons beyond privacy or security of its customers.

Extracting Text Messages from Google Accounts

Wednesday, April 26th, 2017

Elcomsoft Cloud Explorer 1.30 can now pull SMS (text) messages straight off the cloud, and offers enhanced location processing with support for Routes and Places. In this article, we’ll have a close look at the new features and get detailed instructions on how to use them. The first article will discuss the text messages, while enhanced location data will be covered in the one that follows.

Text Messages: Part of Android Backups (sort of)

Before we begin extracting text messages, let us check where they come from. As you may know, Android 6.0 has finally brought automated data backups. While Android backups are not nearly as complete or as comprehensive as iOS backups, they still manage to save the most important things such as device settings, the list of installed apps and app data into the cloud. Being a Google OS, Android makes use of the user’s Google Account to store backups. Unlike Apple, Google does not count the space taken by these backups towards your Google Drive allotment. At the same time, Google allows for a very limited data set to be saved into the cloud, so you can forget about multi-gigabyte backups you have probably seen in iOS.
