1. What is the CYRON ransomware?

• Ransomware name: CYRON Ransomware
• Added Extensions: .CYRON
• Ransom: 50 Euro in PaySafeCard

The CYRON ransomware restricts access to data by encrypting files with the .CYRON extension. It then attempts to extort money from victims by asking for “ransom,” in form of a PaySafeCard, in exchange for access to data.

The CYRON ransomware targets all versions of Windows including Windows 10, Windows 8.1 and Windows 7. This infection is notable due to how it encrypts the user’s files – namely, it uses AES-265 and RSA encryption method – in order to ensure that the affected user has no choice but to purchase the private key.

When CYRON ransomware infects a PC it will scan all the drive letters for targeted file types, encrypt them, and then append the .CYRON extension to them. Once these files are encrypted, they will no longer able to be opened by your normal programs. When CYRON ransomware has finished encrypting the victim’s files, it will also display a ransom note.
These files are located in every folder that a file was encrypted as well as in the user’s Startup folder so that they are automatically displayed when a user logs in. These files will contain the information on how to access the payment site and get your files back.

The message of the CYRON ransom note is:

When the infection has finished scanning your computer it will also delete all of the Shadow Volume Copies that are on the affected computer. It does this so that you cannot use the shadow volume copies to restore your encrypted files.

2. How did the CYRON ransomware get on my computer?

The CYRON ransomware is distributed via spam email containing infected attachments or links to malicious websites. Cyber-criminals spam out an email, with forged header information, tricking you into believing that it is from a shipping company like DHL or FedEx. The email tells you that they tried to deliver a package to you, but failed for some reason. Sometimes the emails claim to be notifications of a shipment you have made. Either way, you can’t resist being curious as to what the email is referring to – and open the attached file (or click on a link embedded inside the email). And with that, your computer is infected with the CYRON ransomware.

3. Is it possible to decrypt files encrypted by CYRON ransomware?

No, at this time it’s not possible to recover the files encrypted by the CYRON ransomware.

CYRON ransomware is notable due to how it encrypts the user’s files – namely, it uses AES-265 and RSA encryption method – in order to ensure that the affected user has no choice but to purchase the private key. The RSA public key can only be decrypted with its corresponding private key. Since the AES key is hidden using RSA encryption and the RSA private key is not available, decrypting the files is not feasible as of this writing.

Brute forcing the decryption key is not realistic due to the length of time required to break an AES encryption key. Unfortunately, once the CYRON encryption of the data is complete, decryption is not feasible without paying the ransom.
Because the needed private key to unlock the encrypted file is only available through the cyber criminals, victims may be tempted to purchase it and pay the exorbitant fee. However, doing so may encourage these bad guys to continue and even expand their operations. We strongly suggest that you do not send any money to these cyber criminals, and instead address to the law enforcement agency in your country to report this attack.
