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.
