What is Dec ransomware?

Discovered by Jakub Kroustek, Dec is a part of the Dharma ransomware family. This malicious program encrypts files, modifies their filenames and provides victims with instructions about how to contact the developers in a pop-up window and text file (these are ransom messages).

Dec renames encrypted files by adding the victim's ID, de_cryption@tuta.io email address and appending the ".dec" extension to filenames. For example, it renames "1.jpg" to "1.jpg.id-1E857D00.[de_cryption@tuta.io].dec", "2.jpg" to "2.jpg.id-1E857D00.[de_cryption@tuta.io].dec", and so on. A text file called "FILES ENCRYPTED.txt" is also created.
