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.

WhatsApp: The Bad Guys’ Secret Weapon

Wednesday, July 19th, 2017

WhatsApp is one of the most secure messengers with full end-to-end encryption. Messages exchanged between WhatsApp users are using an encrypted point-to-point communication protocol rendering man-in-the-middle attacks useless. WhatsApp communications are never stored or backed up on WhatsApp servers. All this makes government snooping on WhatsApp users increasingly difficult.

WhatsApp has more than a billion users. WhatsApp makes use of the Open Whisper Signal communication protocol to secure communications with end-to-end encryption. WhatsApp users rely on that security to freely exchange messages, discuss sensitive things and, with limited success, avoid religious and political oppression in certain countries. Today, some governments attempt to criminalize WhatsApp protection measures, ban end-to-end encryption and do everything in their power to undermining trust in secure communication tools. What is it all about, and how to find the right balance between public safety and security is the topic of this article.

Physical Acquisition Is…

Thursday, July 13th, 2017

…dead? Not really, not completely, and not for every device. We’ve just updated iOS Forensic Toolkit to add physical support for some previously unsupported combinations of hardware (32-bit devices) and software (iOS 9.1 through 9.3.4). The intent was helping our law enforcement and forensic customers clear some of the backlog, finally taking care of evidence kept on dusty shelves in the back room. In order to do the extraction, you’ll need to install the “Home Depot” jailbreak from http://wall.supplies and, obviously, Elcomsoft iOS Forensic Toolkit 2.30.

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.
