Custom Hash Algorithm / Modify or Add new mode

[tkapo]

Hi,
Im trying to crack a hash like this:
bcrypt( md5( md5($salt).md5($pass) ) )

Basically its just the existing MyBB hashing function with bcrypt added to it.
Any idea how i can achieve this in hashcat? Or are there other cracking tools which support custom algorthims?

I see somebody got their hands on the Cracked.to database...

Is the new MyBB always using bcrypt( md5( md5($salt).md5($pass) ) )? Do we need a new module?

No, those were manually re-hashed.
