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…)

Android 8.0 Oreo: Your Text Messages Are in the Cloud Now

Thursday, September 21st, 2017

In each major Android update, Google improves security on the one hand, and moves a few more things to the cloud on the other. The recently finalized and finally released Android 8.0 Oreo adds one important thing to all devices running the newest build of Google’s OS: the ability to back up SMS text messages into the user’s Google Account.

If you follow our blog, you may recall we’ve already talked about the issue a few months ago. Back in April, we were excited to introduce a new feature to Elcomsoft Cloud Explorer, enabling cloud acquisition of text messages from Google Account. Back then, the feature was limited strictly to Google Pixel and Pixel XL devices running Android 7 Nougat.

The release of Android 8.0 Oreo has finally brought the feature to all devices regardless of make and model, allowing any device to back up and restore SMS text message via the user’s Google Account.

We updated Elcomsoft Cloud Explorer accordingly, enabling support for cloud-based SMS extraction for devices running Android 8. There aren’t many of those yet aside of Google Pixel and Pixel XL devices, but many users of Nexus 5x and 6p have already received the update. More devices will follow. Let’s have a look at how this new feature works. Before we begin, let us first clear the confusion that arises between Android data sync and data backups. (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.

New Security Measures in iOS 11 and Their Forensic Implications

Thursday, September 7th, 2017

Apple is about to launch its next-generation iOS in just a few days. Researching developer betas, we discovered that iOS 11 implements a number of new security measures. The purpose of these measures is better protecting the privacy of Apple customers and once again increasing security of device data. While some measures (such as the new S.O.S. sequence) are widely advertised, some other security improvements went unnoticed by the public. Let us have a look at the changes and any forensic implications they have.

Establishing Trust with a PC Now Requires a Passcode

For the mobile forensic specialist, one of the most compelling changes in iOS 11 is the new way to establish trust relationship between the iOS device and the computer. In previous versions of the system (which includes iOS 8.x through iOS 10.x), establishing trusted relationship only required confirming the “Trust this computer?” prompt on the device screen. Notably, one still had to unlock the device in order to access the prompt; however, fingerprint unlock would work perfectly for this purpose. iOS 11 modifies this behaviour by requiring an additional second step after the initial “Trust this computer?” prompt has been confirmed. During the second step, the device will ask to enter the passcode in order to complete pairing. This in turn requires forensic experts to know the passcode; Touch ID alone can no longer be used to unlock the device and perform logical acquisition.

iOS 9.3.5 Physical Acquisition Made Possible with Phoenix Jailbreak

Thursday, August 24th, 2017

If you watch industry news, you are probably aware of the new Phoenix jailbreak… or not. During the last several years, getting news about iOS jailbreaks from reliable sources became increasingly difficult. The sheer number of fake Web sites mimicking the look of well-known resources such as Pangu and TaiG made us extra careful when trying newly published exploits.

Back to Phoenix. This thing is for real. Phoenix claims support for iPhone 4s, 5/5c, iPad 2/3/4, iPad mini, and iPod 5g running the last version of iOS 9.3.5. We were able to verify these claims by successfully jailbreaking several test devices and using Elcomsoft iOS Forensic Toolkit to perform full physical acquisition (as in imaging and decrypting the physical data partition).

With Phoenix jailbreak, iOS Forensic Toolkit can perform physical acquisition of Apple’s 32-bit devices running iOS 9.3.5, which happens to be the last version of iOS 9. Users of iOS Forensic Toolkit can perform physical-level imaging and decryption of the data partition, decryption and examination of keychain items, and enjoy full unrestricted access to sandboxed app data. This level of access is simply not possible with any other acquisition methods. As an example, physical acquisition of jailbroken devices enables forensic access to saved email messages, passwords, and full conversation logs saved by some of the most secure messengers such as WhatsApp, Telegram, Signal, Skype and Facebook Messenger. Compared to iOS backup analysis, this method adds access to browser cache and temporary files, email messages, extended location history, and data that belongs to apps that explicitly disable backups.

Acquiring Apple’s iCloud Keychain

Tuesday, August 22nd, 2017

Who needs access to iCloud Keychain, and why? The newly released Elcomsoft Phone Breaker 7.0 adds a single major feature that allows experts extracting, decrypting and viewing information stored in Apple’s protected storage. There are so many ifs and buts such as needing the user’s Apple ID and password, accessing their i-device or knowing a secret security code that one may legitimately wonder: what is it all about? Let’s find out about iCloud Keychain, why it’s so difficult to crack, and why it can be important for the expert.

What is iCloud Keychain

iCloud Keychain is Apple’s best protected vault. Since iCloud Keychain keeps the user’s most sensitive information, it’s protected in every way possible. By breaking in to the user’s iCloud Keychain, an intruder could immediately take control over the user’s online and social network accounts, profiles and identities, access their chats and conversations, and even obtain copies of personal identity numbers and credit card data. All that information is securely safeguarded.

Why It Can Be Important

Forensic access to iOS keychain is difficult due to several layers of encryption. Due to encryption, direct physical access to a locally stored keychain is normally impossible; the only possible acquisition options are through a local password-protected backup or iCloud Keychain. (more…)

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.
