Daz Ransomware is a New VoidCrypt Variant

ransomware

A new strain of file-encrypting malware going by the name of Daz ransomware was discovered by security researchers. The new strain is a member of the broader VoidCrypt ransomware family.

The Daz ransomware works as you would expect - it encrypts the majority of files on the system it is deployed on, affecting media, document, database and most archive file types.

Encrypted files receive a multi-string new extension, consisting of the victim ID string, the contact email used by the ransomware operator and the ".Daz" extension. This means that a file that was formerly called "document.doc" will turn into "document.doc.(victim ID string)(Sc0rpi0@tutanota.com).Daz" once it has been encrypted.

The ransom note is deposited inside a plain-text file called "unlock-info.txt". The ransom note lists no specific ransom amount, only mentioning Bitcoin as the payment method. The full note goes as follows:
