You should read the tips for preventing ransomware found in our forums.

DilmaLocker Ransomware – Overview

DilmaLocker is the name of a cryptovirus that might be considered to be part of a hacktivism agenda, given that it is named after Dilma Rousseff, the former president of Brazil. The following malware threats are also involved in some form of hacktivism:

The virus will change your Desktop background with her image and will encrypt your files and then extort you to pay a ransom to supposedly recover them. The ransomware might be targeted only at Brazillian speaking users, but it seems unlikely to be only aim.

The ransomware also pops up this notification:

DilmaLocker ransomware might make entries in the Windows Registry to achieve persistence, and could launch or repress processes in a Windows environment. Such entries are typically designed in a way to launch the virus automatically with each start of the Windows Operating System.

The note can be previewed right down here, from the following screenshot:

However, you should NOT pay any ransom sum demanded by the crooks. That may only inspire the cybercriminals to continue developing ransomware or commit other crimes.

Your Desktop background will be changed to the following image:

Oops, todos os seus arquivos foram criptografados!!!
Seus documentos: fotos, vídeos, bancos de dados e outros arquivos importantes foram criptografados utilizando o algoritmo AES de 256 bits (mesma criptografia utilizada pelo governo americano para proteger segredos de estado), ou seja, é impossível recuperar seus arquivos sem a senha correta!

In 4 days your files will be DELETED!
Read the file ‘RECUPERE_SEUS_ARQUIVOS.html’ that was created on your desktop.

As seen above, the Desktop background contains parts of the whole ransom note message.

DilmaLocker Ransomware – Encryption

The encryption process of the DilmaLocker ransomware is utilized with the help of the AES encryption algorithm with 256 ciphers or at least that is stated inside the ransom notes. The DilmaLocker virus will encrypt your files while placing the .__dilmaV1 extension to all locked files.

The targeted extensions of files which are sought to get encrypted are currently unknown and if a list is discovered, it will be posted here as the article gets updated. The files used most by users and which are probably encrypted are from the following categories:

  • Document files
  • Audio files
  • Video files
  • Image files
  • Backup files
  • Banking credentials and data

The DilmaLocker cryptovirus could be set to erase all the Shadow Volume Copies from the Windows operating system with the help of the following command:

→vssadmin.exe delete shadows /all /Quiet

The above-stated command could be executed and that would make the encryption process more efficient. That is due to the fact that the command is set to eliminate one of the prominent ways to restore your files. If your computer device was infected with this ransomware and your files are locked, keep reading to find out how you could potentially recover your data.
