As requested by EP_X0FF, here is a small tool for find serial of locker powered by MBRLocker Builder v0.2
Just make a dump of your infected MBR and drop it on the form
if that don't work for you feel free to edit the code, source code and bin attached.

For easily get a dump you can use HideToolz v2.2 by fyyre with the option reboot protection enabled
then just run the locker and make a mbr dump with hdhacker or Hiew.
