Hi everyone, first post here, hope this is the right forum section for this sort of question, hope I've provided details usefully :)




I've got my teeth very firmly into a recovery from CryptoWall on Windows XP.


Now I need to, not just search/find, but copy, retaining folder structure, all the files that have not been affected.


I'm thinking things like:

  • Are there file managers can do copy jobs retaining folder structure? Can Total Commander do that?
  • Comparing headers of files to what they *should* be, given the file extension, could be a way to spot encrypted files
  • Better be sure which filetypes have been affected first...
  • Can *possibly* get my head round writing a script (in PHP though!) to show me all the file Exts that appear in the ListCWall log that just finished
  • No idea about reading file headers though, particularly working in Windows :(



I've got some valuable stuff back (Outlook and Quickbooks), found and recovered some non-encrypted deleted files using R-Studio (seems very good, I might buy it).


I've avoided working on the original drive almost completely and I've got the WinXP install running in VBox (Windows 7 Pro 64bit host) so I feel I'm doing pretty well!


Next move is to scout around a bit with Shadow Explorer before seeing if System Restore helps...




It's a whole lotta fun but I'm stumped so far for a practical solution for collecting together the *good* files that are left.


What does everyone else do in this situation?





thanks Orange Blossom ;)

:welcome: to Bleeping Computer.

A repository of all current knowledge regarding CryptoWall, CryptoWall 2.0 & CryptoWall 3.0 is provided by Grinler (aka Lawrence Abrams), in this topic: CryptoWall and DECRYPT_INSTRUCTION Ransomware Information Guide and FAQ

There are also ongoing discussions in these topics:Rather than have everyone start individual topics, it would be best (and more manageable for staff) if you posted any questions, comments or requests for assistance in one of those topic discussions. Doing that will also ensure you receive proper assistance from our crypto malware experts since they may not see this thread. To avoid unnecessary confusion...this topic is closed.
