What is Kostya Ransomware?

Kostya is a type of malicious software that encrypts your files and demands a ransom payment in exchange for the decryption key.


Kostya was first discovered in December 2016 by security researchers. It is a variant of the Locky Ransomware, which was first seen in February 2016.

How does Kostya Ransomware work?

This ransomware arrives on your computer via email attachments or malicious links. Once it has encrypted your files, it will display a ransom note demanding that you pay a certain amount of money in exchange for the decryption key.

What encryption algorithm does Kostya use?

Kostya Ransomware uses the AES-256 encryption algorithm to encrypt your files. This is a strong encryption algorithm that makes it very difficult to decrypt your files without the decryption key.

How much does Kostya Ransomware cost?

The price of Kostya Ransomware varies depending on the victim, but it typically ranges from $200 to $10,000.

Should you pay the ransom?
