I arrived at work to find my ransom message and lots of .crypt files.   I uploaded the note and a sample to see that it is likely CrptyXXX, and downloaded RannohDecryptor.  (I love this site).


However, every pair of files (.crypt and original) tells me "Encrypted file size does not equal to original".  I have several files I happened to email yesterday, so I have a good source of matching files.   One is a .pdf file, which I cannot edit, so it should definitely be identical.  But I receive this error on every pair I try. 


I the case of the PDF original, properties shows 94,850 bytes, while the encrypted is 95,898 bytes.   Every encrypted file is about 1K larger than it's original, and I'm a bit stuck since Kaperski's tool won't allow that.


Any ideas?

There is an ongoing discussion in this topic where you can ask questions and seek further assistance.Rather than have everyone with individual topics, it would be best (and more manageable for staff) if you posted any more questions, comments or requests for assistance in the above support topic discussion...it includes experiences by experts, a variety of IT consultants, end users and company reps who have been affected by ransomware infections. 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.
