Password can be digit but also letters - BF attack can be time consuming if you will work only on one machine. If you don't have any hints and you want access those backup check iOS version - there was a bug in 10.x which allow very fast attack. If you still got a problem you can drop me PM - we can try to check how much time it can take on our GPUs PCs by distribute attack

Bruteforcing the backup is a matter of GPU power + pure luck at this point.

What about iCloud ? I'd start digging there...

Re: iphone password backup

Hello All,

I have recently removed the iPhone backup encryption from iOS 10.3.3 and 11.1.2 and 11.4 by using the reset settings option.

I am wondering if resetting the user settings is a common way analysts remove the encryption or is bypassing the code using Elcomsoft or Passware the preferred method for a forensic perspective?

If so does anyone know what changes are made?

I have noted that all security features are removed (PIN, Encrpytion and Biometrics) as well as any preset user background images.

Any input will be greatly appreciated.

Kind Regards.

Hi guys,

I'm curious too to know if some data are lost by this operation of resetting.

Thanks a lot for your reply
