Verify that a disk clone is identical to the source drive, by using OSFClone to compare the MD5 or SHA1 hash between the clone and the source drive. The dc3dd format is ideal for computer forensics due to its increased level of reporting for progress and errors, and ability to hash files on-the-fly.
OSFClone can create disk images in the dc3dd format. Boot into OSFClone and create disk clones of FAT, NTFS and USB-connected drives! OSFClone can be booted from CD/DVD drives, or from USB flash drives. OSFClone creates a forensic image of a disk, preserving any unused sectors, slack space, file fragmentation and undeleted file records from the original hard disk. After creating or cloning a disk image, you can mount the image with PassMark OSFMount before conducting analysis with PassMark OSForensics™. An open standard enables investigators to quickly and efficiently use their preferred tools for drive analysis. In addition to raw disk images, OSFClone also supports imaging drives to the open Advance Forensics Format (AFF), AFF is an open and extensible format to store disk images and associated metadata, and Expert Witness Compression Format (EWF). Warning: If it ever gets to the point of having to reset your firmware password, please consult a specialist before attempting any of the advice described in this article.OSFClone is a free, self-booting solution which enables you to create or clone exact raw disk images quickly and independent of the installed operating system. Remember that story from February? When the press discovered that hackers were offering Apple employees in Ireland thousands of euros for their enterprise passwords? We now may know why crooks are willing to pay so much for Apple employee credentials. Only Apple has a real chance to investigate and track the source of these files. These could be insiders working at Apple support centers or even Apple itself. “ So what is happening with all those videos and people claiming they were able to buy SCBO files from websites? My bet is that these guys somehow are able to submit illegitimate requests to Apple’s support system and then sell the SCBO files they receive for some nice fat profit. The online services that were selling SBCO files were obviously fake, or downright illegal. ” Is Apple Support compromised?įurthermore, the researchers also discovered that there was no way to generate an SBCO file without having access to Apple's private encryption keys.

The '3E6D568B' variable is special because if you remove it, the NVRAM will be reset to a default state where the firmware password is not set anymore. Or just locate the variable and erase or modify it directly without reflashing the whole contents. “ If you have a SPI flasher and want to remove an Apple EFI firmware password, what you need to do is to dump the flash contents, remove the 'CBF2CC32' variable (you just need to flip a single bit on its name for example), and reflash the modified firmware. “ My work helped me determine that the EFI variable that contains the firmware password information is 'CBF2CC32.' ”
You can read the step-by-step reverse engineering process on fG!'s personal blog, but the good news is that he managed to find a way to do it.

Since trusting this kind of services and running mysterious code on his laptop did seem like a good idea, the researcher set out to find out how SCBO and Apple's EFI (Extensible Firmware Interface) worked, and if he could find a way to bypass this process. Crooks are selling SCBO files online for $100įG! says he discovered shady online services that were providing SCBO files, but for a fee of $100. If you can't, then you're left on your own. This is all fine and dandy, but only if you can prove ownership of your device with the original sales receipt.
Users give this code to Apple's staff, and they receive back an SCBO file, which they can then put on a USB flash drive they insert into their device, and they can thus remove the password. In case this happens, users can call Apple Support, and during boot-up, they're guided through the process of pressing five keys simultaneously to make a long code appear on their screen. Just like any password, users tend to forget it once in a while. Apple helps authorized users reset their firmware password
