DilmaLocker ransomware virus. How to remove? (Uninstall guide)
DilmaLocker is yet another virtual extortion tool set to encrypt your files
DilmaLocker is a new ransomware-type virus that compromises victim’s files to demand a ransom[1]. The malicious software employs AES-256 cipher to encode all user’s files and leaves a ransom note called RECUPERE_SEUS_ARQUIVOS.html and dilminha.dat. When encrypting the data, ransomware appends .__dilmaV1 file extension to each file.
The malicious virus triggers a pop-up message saying “Seus arquivos foram criptografados,” which roughly translates from Portuguese to “Your files were encrypted.” The virus presents itself as Trojan.Ransom.Win32.Dilma.Locker. The virus also changes the background image that suggests writing to dilmaonion@keemail.me to get data recovery instructions. Dilma virus also informs the victim that all files on the system will be deleted after four days.
DilmaLocker authors demand to pay 3000 Brazilian Reals in Bitcoin. The sum is equal to 968 US dollars. However, the criminals admit that they are ready for negotiations if the user cannot afford to pay a ransom of nearly thousand USD.
In addition, cyber criminals suggest to prove their intentions and say that they can decrypt one file of victim’s choice. The only condition is that the file cannot be larger than 3MB in size.
However, we do not recommend paying the ransom because you get no guarantees that your files will be decrypted. The criminals can disappear at any moment and leave you with piles of encrypted data. Therefore, if your computer got hit by ransomware, we recommend you to remove DilmaLocker virus immediately. You should consider using a good anti-malware software such as Reimage to eliminate it.
