Hi and thank you for your time beforehand.

 

Trying to help a friend that has no idea about "tech". Unfortunately all I have are some samples. No ransom note, no email nothing :(

The technician that "cleaned" his PC left only his encrypted files behind. 

 

ID Ransomware doesn't give me back something.

 

SHA1: 56cce147f511eff4324166a7478882cbc26771ec

SHA1: 735c2604d740fc541488d3400c82fd64e39ddce2

 

I have a .docx file and a .jpg

 

Both start with 16 45 99 44 3D 0D BE 27 B2 A9 6A 43 C3 28 2A D0

 

If someone recognizes this pattern..

I don't recognize any filemarkers in them. The fact those two files both have the same first 16 bytes means it could just be an ID or IV used for the encryption. Doesn't necessarily mean it is a filemarker without analyzing the malware.

 

Only way to identify would be with a ransom note or the malware executable.

 

If this was encrypted a few years ago, I would suggest it could be CryptoWall 3.0 or 4.0, they left what I think was an IV as the first 16 bytes of every file.
