Local backups made with iTunes can be protected with a password. Even if someone gets your iPhone, they’ll have to start brute forcing your passcode within one hour – or they won’t be able to start it at all. The newly implemented USB Restricted Mode disables the USB port on your iPhone one hour after you last unlocked the device (fingerprint, Face ID or passcode) or one hour after you disconnected it from a trusted USB accessory. Starting with iOS 11.4.1 beta, Apple went an extra mile in an attempt to protect your iPhone against attackers trying to brute force your passcode. Even if they take the memory chip off, they won’t get anything meaningful due to the encryption. If you protected your iPhone with a 6-digit passcode (which you really should, and which is the default since at least iOS 10), most of your information is securely encrypted until you first unlock your iPhone after it completes the boot sequence. Thanks to the iOS keychain, we enjoy the additional layer of protection for our passwords and other sensitive information. Speaking of the current pack of iOS versions (including iOS 11.4 release, 11.4.1 public beta and 12.0 first developer beta), we have full-disk encryption with decryption keys derived from the user’s passcode and protected by Secure Enclave. We praised the iOS security model on multiple occasions. We’ll tell you how to defend your data and your Apple account if they have your iPhone and know your passcode. This time around we’ll be playing devil’s advocate. We teach and train forensic experts on how to extract and decrypt information, how to download information from iCloud with or without the password, how to bypass two-factor authentication and how their iPhone falls your complete victim if you know its passcode. We routinely publish information on how to break into the phone, gain access to information and extract as much evidence as theoretically possible using hacks (jailbreaks) or little known but legitimate workarounds. ElcomSoft does not need an introduction as a forensic vendor.
