DilmaLocker Ransomware – Infection

DilmaLocker ransomware could spread its infection with various methods. A payload dropper which initiates the malicious script for this ransomware is being spread around the World Wide Web, and researchers have gotten their hands on a malware sample. If that file lands on your computer system and you somehow execute it – your computer system will become infected. You can see the detections of such a file on the VirusTotal service right here:

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

DilmaLocker ransomware might also distribute its payload file on social media and file-sharing services. Freeware which is found on the Web can be presented as helpful also be hiding the malicious script for the cryptovirus. Refrain from opening files right after you have downloaded them. You should first scan them with a security tool, while also checking their size and signatures for anything that seems out of the ordinary. 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.

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.
