  Thanks! Guess my search was too specific. The important bit: > The malware is programmed to encrypt files on an infected personal computer three days after the original infection, according to Olson. Anyone who may have been hit, update your backups NOW so you can restore the files.

    Careful not to backup the malware infection though...

      Of course, and if you only have the one backup drive, be wary of connecting it to an infected computer with read/write access. Link posted in another comment suggests that this malware has encryption of Time Machine backups in development (should be safe this time around?). Safer option would be to create a write-only network share on another computer and copy files to that.
