Yet another virus from the XTBL ransomware variants has popped out into the open. Similar to other XTBL variants this virus also encrypts the files of the infected computer making them no longer openable. A ransom note is left after the encryption process is completed which is typical for this type of virus. The payment e-mail is DIGITALKEY2@163.com and the virus may use an AES encryption algorithm that is combined with an RSA cipher. Not only this but DIGITALKEY2 ransomware also uses different file extension that includes the unique identification number, the e-mail and the identical .xtbl file extension which is added after the e-mail address. Users who have been affected by this virus are strongly advised not to perform any type of negotiations with the cyber-criminals and any payments to them.
Sensors Tech Forum team is currently investigating this threat. The article will be updated as soon as more information for DIGITALKEY2 ransomware is discovered.

The malicious files may also be located in the %Startup% folder which is most often the case, because this folder makes files, like the encryptor or the ransom note run on system startup.
However, if the target PC has protection enabled for this folder the DIGITALKEY2 ransomware may use the registry entries that allow for the automatic startup of a file no matter where it is located on the computer. The usual targeted keys for that are:
As soon as the encryption file of DIGITALKEY2 is ran, the virus immediately begins encrypting:
- Audio files.
- Microsoft Office Documents
- Other files associated with often ran programs.
The encrypted files have unique keys generated specifically for them and these keys are usually sent to the cyber-criminals. A file encrypted by DIGITALKEY2 ransomware looks like the following:
