CryptON Virus – Delivery Ways

The CryptON ransomware could be delivered by using various ways. The file which drops the payload for the ransomware containing the malicious script can be delivered through a few different sources. You can see an example of such a file, examined by the VirusTotal service, right here:

The CryptON virus could deliver the dropper for the payload on social media websites as well as services for file-sharing. Freeware programs might be promoted as helpful, but at the same time might be hiding the downloader for the payload. Don’t be opening files right after you have downloaded them, especially if an unknown source has delivered them. You should scan such files with a security tool first and afterward, check for anything that seems out of the ordinary. You can read the ransomware preventing tips topic in our forum.

CryptON Virus – Detailed Description

The ransomware cryptovirus that is discussed, was dubbed CryptON because there are instances of that phrase being mentioned in its code. The ransomware encrypts your files with a distinctively long extension, which contains an email address. One of the emails that are used is [email protected], which is connected with another Portuguese ransomware that is thought to be a variant of this one – GarryWeber ransomware.

The CryptON ransomware could make entries in the Windows Registry to achieve a higher state of persistence. Such registry entries are usually created to serve the purpose to launch the virus automatically with every boot of the Windows operating system and stop processes from running.

The CryptON ransomware is presented as a variant of Cryptolocker in Portuguese. One such evidence of that is inside the ransom note, which appears after the encryption process, and is written in a mixture of Portuguese and English. You can preview the message from the below screenshot:

The message states the following:

2. O software anti-virus pode remover Cryptolocker, mas nao pode descriptografar seus arquivos. A unica maneira de recuperar seus arquivos – e pagar pela chave de descriptografia.
3. Informacoes para especialistas em TI:
Os dados foram criptografados com o algoritmo AES (Rijndael) com o comprimento da chave de sessao de 256 bits. A chave de sessao e criptografada com o algoritmo RSA (2048 bits). A chave publica esta incluida no Cryptolocker. A chave privada para descriptografia da chave de sessao e armazenada somente em meu banco de dados. Para quebrar essa chave, voce precisara de mais de um milhao de anos.

The above ransom message points to the ransom note that is apparently inside a file called ”COMO_ABRIR_ARQUIVOS.txt”. The ransom note states all demands of the cybercriminals, including the price, along with everything else. The note is also written in a mixture of the Portuguese and English languages. You can preview it down here:

The criminals that stand behind the CryptON ransomware virus are trying to present it as CryptoLocker ransomware. You should NOT under any circumstances pay these crooks. Nobody could guarantee if your files will get recovered or not. Furthermore, you should not ever give money to criminals, as this will probably just support them financially and motivate them to create other ransomware viruses and do more criminal activities.

CryptON ransomware searches to encrypt the following file extensions:

→.bmp, .doc, .docx, .jpg, .mp3, .pdf, .png

A full list of file extensions which can get encrypted is not out yet, but the article will be duly updated if such a list shows up. The encryption algorithm that is stated to be used is a mixture of 256-bits AES and 2048-bits RSA. Every file that gets encrypted will have one and the same extension appended to each of them, which is .[email protected]_. The extension doesn’t affect the file names, neither their original extensions and is placed as a secondary extension.

The CryptON cryptovirus is very likely to delete the Shadow Volume Copies from the Windows Operating System by executing the following command in the Command Prompt:

→vssadmin.exe delete shadows /all /Quiet

The virus might execute more commands in the Command Prompt, too. Continue to read below and see what types of ways you can try out to potentially restore some of your files.
