Puma Ransomware, that started to hit thousands of computers in November, 2018, is, actually, nothing but another variation of STOP Ransomware. Current version appends .puma, .pumax or .pumas extensions to encrypted files, and that is why it has such nickname. Virus uses the same name for ransom note file: !readme.txt. Developers tried to confuse ransomware identification services and users by adding new extensions, but using the same templates, code and other signs unequivocally indicate belonging to a certain family. As we see from the name of the executable: updatewin.exe, it pretends to be a Windows update. Puma (STOP) Ransomware still uses RSA-1024 encryption algorithm. Current version of Puma Ransomware was developed in Visual Studio 2017.

The pattern of the filename after encryption looks like this: file called 1.doc will be converted to 1.doc.id-{8-digit-id}.[{email-address}].fire.
