hashcat Forum

As you could read in this post I explained a walk-through for extracting the FileVault hash.
I also explained that this method wasn't working anymore since macOS 10.14 (Mojave).
The tool from JtR (apfs2john, a fork of apfs-fuse) was for the same reason not working anymore.

It appeared that Apple used a 4096 byte sectors in the partition table. (Read this issue on GitHub for more details)

Finally, apfs-fuse got updated and it got forked.
You'll find a working "APFS-hash-extractor" (named apfs2hashcat) on this Github: https://github.com/Banaanhangwagen/apfs2hashcat

The readme explains also the reason of multiple extracted hashes.

Happy cracking!

Very cool, good job

Hello,
i tried the Linux-tool (apfs2hashcat) to extract the hash for hashcat but get an error on the "make" command.



Is it possible to convert the EncryptedRoot.plist.wipekey manual to the hashcat needed format ?
(i still copied it to my workfolder)


edit:// I´m using Windos-Subsystem-Linux Ubuntu 18.04 LTS

linux@MSI:/mnt/d/0_Work/apfs2hashcat/build$ sudo apt install libfuse3-dev

E: Unable to locate package libfuse3-dev


Isn´t there an easy way to convert the EncryptedRoot.plist.wipekey to the hashcat-format by myselfe ?

normally you would need to do everything that the extraction tool needs to do. so it could turn out to be more complicated than you might think (but of course there are exceptions to this as always) .

Why don't you just use a normal ubuntu operating system

Try searching for the include file with:

and after that you install the package that is returned (in my case it was libfuse3-dev , but it could also be slightly different, e.g. libfuse-dev, but I think the non-3 version is not providing the fuse3 headers)

Normaly i only use win-10 because the other tools i use are only for Win os.
WSL i a neice and fast way to manipulate or have an look at huge password files.

Now i testet to make the file with ccmake (and disabled Fuse) no it compiles and work.
..i still have to test if the cracking will work so i can go on with an not-known-pw

edit:// cracked,.... very nice, thanks for your support

I couldn´t find some benchmarks so here are my results:

Are there any methods for extracting the has from 10.15? Looking for that for a non-T2 Mac w/out the PW and FV2

Sure, just read the first post of this thread...
