What is DDT ransomware? And how does it execute its attack?

DDT ransomware is yet another dangerous ransomware threat that could encode all the important data in a computer, making them inaccessible. It seems to be a new variant of the infamous GlobeImposter 2.0 ransomware. It adds a “.{[email protected]}DDT” extension in every file it encrypts. Apart from the email address and extension it uses, there are no other significant changes in this new variant as it still follows the same pattern as other variants of GlobeImposter 2.0 in executing its attack.

DDT Ransomware

Once it manages to invade a computer, it starts to execute its attack by dropping its malicious payload in the system which will establish a connection between the infected device and a remote Command and Control server where it also downloads additional malicious files that helps it in executing its attack. These malicious files also make alterations in the Windows Registry in order to run on every system boot. Once these changes are applied, the search for files to encrypt began.

After finding its targeted files, it encrypts them using a strong encryption algorithm in locking its targeted data and adds the “.{[email protected]}DDT” extension after it completes the encryption. Following data encryption, the crypto-virus creates a file named “how_to_back_files.html” that contains the following content:

“YOUR PERSONAL ID

ENGLISH
YOUR FILES ARE ENCRYPTED!
ALL YOUR IMPORTANT DATA HAS BEEN ENCRYPTED.
To recover data you need a decryptor.
