Elcomsoft Phone Breaker Extracts and Decrypts iCloud Keychain
“iCloud Keychain was long considered to be unbreakable”, says Vladimir Katalov, ElcomSoft CEO. “Gaining access to passwords from iCloud Keychain was a major challenge. iCloud Keychain is a complex and extremely secure online password storage and storage synchronization system. Building a tool that can enroll into iCloud Keychain was a major achievement.”
By extracting user’s saved passwords from iCloud Keychain, experts can log in to the user’s online accounts, access social network accounts, and extract chats, messages and postings. In addition, saved passwords are perfect for building custom dictionaries for targeted brute-force attacks on user’s encrypted containers, archives and documents.
Information is obtained directly from the user’s iCloud account. In order to access iCloud Keychain, the original Apple ID login and password are required. Access to a trusted device is mandatory if two-factor authentication is enabled on the user’s account, along with device passcode (iOS) or system passwords (macOS) of a device already enrolled to iCloud Keychain. Without two-factor authentication, the expert will need to confirm a notification prompt on one of the trusted devices and supply the user’s iCloud Security Code.
iOS and macOS implement a system-wide protected storage for sensitive information such as Web site logins and passwords, Wi-Fi passwords, credit card data and so on. These items are stored in the system keychain. For iOS devices, the keychain can be saved and restored via local or cloud backups.
Forensic access to iOS keychain is difficult due to several layers of encryption. The keychain saved into an iCloud backup is securely encrypted with a hardware-based encryption key, and can only be restored onto exactly the same device it was saved from. Forensic access to hardware-encrypted keychains is impossible with very few exceptions (legacy devices, jailbreak). A password-protected local backup can be used for keychain extraction; however, if the backup is protected with a long, unknown password, brute-forcing that password may take significant time of may not be possible.
In addition to local keychains, Apple offers a cloud password storage and synchronization system, the iCloud Keychain. iCloud Keychain is a service designed to keep user’s passwords synchronized across multiple devices. The service provides a secure storage, authentication and synchronization mechanism, allowing newly registered devices to obtain keychain items from the user’s other enrolled devices. Access to iCloud Keychain is securely protected with multiple layers of protection including industry-standard encryption and access restrictions imposed by the chain of trust.
The system is so secure that, until now, third-party access to iCloud Keychain was through to be impossible.
Elcomsoft Phone Breaker 7.0 becomes the first tool to access passwords and payment information secured by iCloud Keychain. In order to gain access, the user’s original Apple ID and passwords (as well as a 2FA code) are required. In addition, the expert must approve the request on an already enrolled device (if there is no two-factor authentication on that account). If two-factor authentication is enabled on the user’s account, the expert will have to provide device passcode for any iOS device already enrolled for iCloud Keychain, or system password if the enrolled device is a Mac.
