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 PC will become infected. You can see the detections of such a file on the VirusTotal service down here:

DeadSec-Crypto 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.

DeadSec-Crypto Ransomware – More Information

DeadSec-Crypto is a virus that encrypts your files and extorts you to pay a ransom to get them back. Malware researchers have noted that for the time being it is still in its development stages, so it will encrypt only some test files which it creates itself. The main target is possible to be people from Brazil, as its ransom note is written in Brazilian Portuguese, but the rest of the World could get their computer machines infected, as well.

DeadSec-Crypto ransomware could make entries in the Windows Registry to achieve persistence, and probably 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 is written in Brazilian Portuguese, as it uses that dialect specifically, and gives details about how you could restore your files by paying a ransom. Fortunately, even though this is version 2.1, your personal files will be unaffected and only some test files will be. You can view the ransom message that loads after the encryption process in this picture:

That ransom message reads the following:

Porque recebi isso?

Você foi vitma de um ransomware e todos seus dados foram roubados e criptografados pela DeadSec todos arquivos estao com extensão .locked e com a hash SHA256SUM praticamente impossível de recuperar nos temos todos seus dados inclusive senhas, documentos e arquivos dentre outras coisas pessoais como Cartões e etc.

O que fazer?

Você precisara doar uma quantia de 0.05 Bitcoins que em Reais=R$100.00 para o Endereço abaixo, para doar a quantia você precisa comprar Bitcoins com dinheiro real em: após enviar os bitcoins para o endereço, confirmaremos a transação e enviaremos uma chave para seu email e você tera seus arquivos e senhas

Você tem o prazo de:

Endereço: 1Mx4Zgz5nYmFPPSUS6TbF2SfVP4xfcghBu
Caso nao envie a quantia em 1 Semana, vazaremos todos seus dados.
Link Label 1

A rough translation of that message in English states the following:

Why did I receive this?

You were victim of a ransomware and all your data was stolen and encrypted by DeadSec all files are with .locked extension and with the SHA256SUM hash virtually impossible to recover in we have all your data including passwords, documents and files among other personal things like Cards and etc.

What to do?

You will need to donate an amount of 0.05 Bitcoins that in Reais = $ 100.00 to the Address below, to donate the amount you need to buy real money Bitcoins at: after sending the bitcoins to The address, we will confirm the transaction and send a key to your email and you will have your files and passwords

You have the deadline:

Address: 1Mx4Zgz5nYmFPPSUS6TbF2SfVP4xfcghBu
If you do not send the amount in 1 Week, we will leak all your data.
Link Label 1

The note of the DeadSec-Crypto ransomware states that your files are encrypted. A ransom sum of 0.05 Bitcoin or the equivalent of 100 Brazilian Reais is demanded as payment for potentially unlocking your files (if they are encrypted). As Bitcoin has grown in price quite a lot in the last few months that shows that the text is not current. What is more interesting – the note states that your files will be leaked, so that still counts as a Doxware Virus, even though it is still in development.

Even if your files were locked by a newer version of this ransomware, you should still NOT under any circumstance pay the ransom. Your files may not get restored, and nobody could give you any real guarantee. Moreover, giving money to cybercriminals will likely motivate them to create more ransomware or do other criminal activities.

DeadSec-Crypto Ransomware – Encryption Process

Currently, the ransomware is still in development, although it already has a few variants released. While being tested it only encrypts a couple of files, which itself creates inside a folder called AAAAAA with a random length of the letter “A”. A list with file extensions that the DeadSec-Crypto ransomware will probably seek to encrypt when it is out of its test-phase, would probably be the following:

→.7z, .bmp, .doc, .docm, .docx, .html, .jpeg, .jpg, .mp3, .mp4, .pdf, .php, .ppt, .pptx, .rar, .rtf, .sql, .tiff, .txt, .xls, .xlsx, .zip

Those files are the most widely-used ones for common Windows users, making the list viable. All of the files that get encrypted will receive the same extension appended to them, and that is: .locked. Many viruses have used that extension, but a more recent example is the Portuguese WinSec HiddenTear Ransomware Variant.

The DeadSec-Crypto cryptovirus might be tweaked in the future 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

In case the command stated above is executed that would make the encryption process more efficient as it will eliminate one of the ways for restoring your files. If your PC was infected with this ransomware and your files are locked, read on through to find out how you could potentially recover your data.
