As shown above, the file has been disguised as a .pdf, while it is actually a binary file.

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 of the DilmaLocker ransomware states that your files are encrypted and that you need to pay 3,000 Brazillan Reias in the Bitcoin cryptocurrency, which equals 972 US dollars at the time of writing. 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!

A rough translation in English would look like the following:

Oops, all your files have been encrypted !!!
Your documents: photos, videos, databases and other important files were encrypted using the 256-bit AES algorithm (same encryption used by the US government to protect state secrets), ie it is impossible to recover your files without the correct password!

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.
