What is Zoh Ransomware?
Zoh Ransomware is a cryptovirus, which is a member of the Dharma Ransomware family, which more than once shone in the tops of cryptovirus articles and this is not an accident. First of all, you need to understand what exactly Zoh does. It infiltrates the user’s PC and encrypts user files of various kinds and formats. For example, it can encrypt MS Office documents, audio and video files, archives and multimedia, in a word, those files that the user does not want to lose ever, that is why the question of how to remove Zoh Ransomware is so acute.
After encryption, Zoh Ransomware assigns the simple extension .zoh or compound extension [user ID].[email@example.com].zoh to the attacked files, as a result of which it becomes unusable.
Here are some examples of how your files can change under the influence of Zoh Ransomware:
nature.png - nature.png.id-5483214.[firstname.lastname@example.org].zoh
report.docx - report.docx.id-5483214.[email@example.com].zoh
trombone.m4a - trombone.m4a.id-5483214.[firstname.lastname@example.org].zoh
Looking ahead, we note that the first part of the extension is an email address for communicating with attackers.
The cryptovirus creates a special text file RETURN FILES.txt that contains the detailed scammers’ requirements. Here are the note’s content and image:
