What does Czech Ransomware do?

Czech Ransomware enters computers secretly and then tries to convince users that their files are encrypted. Of course, it is said that the only way to decrypt them is to pay CZK 200 (approximately $8.5). The payment has to be done via the Paysafecard, which is a popular prepaid payment method, within two days. It is said that the only way to unlock files is to pay the required money because these files are encrypted using the encryption algorithm AES-256, which is very hard to crack. Of course, users cannot check whether or not their files have really been encrypted because they cannot access their Desktops, so they believe every word they see written in the screen-locking message (you can find the message translated into English below).

As researchers at have managed to find out, the truth is that Czech Ransomware does not lock files like other ransomware infections at the time of writing. Of course, the version that will be released in the future might do what it says. If it happens that you encounter such a version, we still do not think that you should pay money to cyber criminals. First of all, they will, probably, not unlock files for you even if you make a payment. Secondly, users often find that free decryptors work for them.

Some users believe that they will get rid of the full-screen message belonging to Czech Ransomware by restarting the computer; however, they soon find out that it is not true because this computer infection launches together with the Windows OS and the screen is locked again. This infection is capable of launching itself again because it creates the Value with a random name in the Run registry key (HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run). If you fully remove Czech Ransomware from your computer, this Value will disappear too.

Where does Czech Ransomware come from?

Last but not least, cyber criminals can make those emails look like they are sent from a good sender, e.g. a friend or a reputable company.
