Nokia E72 - Bypassing RAM+Card encryption

Nokia E72 - Bypassing RAM+Card encryption

I just realized something interesting with my E72 - people can access my data even without knowing the password.


Details are as follows:

 

-E72 firmware 022.007. Both memory and MicroSD card are encrypted. Phone set to auto-lock at every 20 minutes.

 

 I have an alternate home screen application installed (Voyager Home Screen) and just noticed that possible to invoke Voyager even after the phone has been "locked" (encrypted). Using Voyager I can load up any file management tool, for instance X-Plorer and access the card and any files.

 

 All one has to to is unlock the keyboard, there is no need to know the lock code or input it.

 

 Perhaps this has something to do with the way Voyager Home Screen works but it made me realize that perhaps the data isn't secure at all... even with encryption.

I'm on 22.007 and while the phone memory appears to encrypt properly (i.e. it takes several mins to encrypt/decrypt), encrypting the card is instantaneous! I suspect card encryption isn't actually working ... though I haven't tried reading the card elsewhere yet. Mark Enderby

Re: Nokia E72 - Bypassing RAM+Card encryption

Hi,

 

thanks for posting on my post about phone memory encryption and OVI Maps (and other applications) not working.

About the memory card encryption.... I have firts locked the memory card with a password, after then have enabled encryption with encryption key saved to "other" folder.

Well, it's about one hour now that it is encrypting the SD card. So it is not istantaneous as someone else said.

I have to say that I have also phone lock enabled in addition to memory card pasword lock.

Maybe the memory encryption works only with that other settings in place.

Re: Nokia E72 - Bypassing RAM+Card encryption

Well I have another update to this issue...  I have accidentally hit the EXIT button during encryption and then the phone restarted. I then disabled memory card encryption and it took about one hour. After that I had some corrupted files in my microSD, some videos that I added later. The original OVI Maps and other files were not affected.

OK, I then decided to retry the encryption process. I enabled the encryption and it was enabled istantaneously as other people said. I then wondered what should it be. Then I came to my mind that probably the phone uses the memory card lock password to generate the encryption key. So I CHANGED the memory card lock password and enabled memory card encryption again. Well the encryption is going on right now (at 10% after 15 minutes on 16GB). So it seems that you firstly have to set the memory lock password and then enable memory card encryption, in that way the card would be encrypted juat as the phone memory encryption works.

I thought I'd found the answer to my card encryption problem. However, setting the card password didn't make any difference and I still get the "instant encryption" problem Mark Enderby
