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 garryweber@protonmail.ch, 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:

Sua identificacao pessoal:
id- [REDACTED] ————————-
Toda a sua informacao importante foi criptografada.
Para recuperar seus dados precisa de um descodificador.
Para receber o decodificador deve pagar pela descodificacao.
Compre 1 BTC nestes sites:
Envie 1 BTC para a decodificacao
Depois de pagar:
1. Enviar captura de ecra ou foto do pagamento para o endereco: steaveiwalker@india.com
2. No caso de voce nao receber uma resposta, por favor me envie um e-mail aqui: steavewalker@163.com
3. Se voce quiser permanecer anonimo ou se voce nao esta recebendo uma resposta, tente usar a mensagem bit (bitmessage.ch) e use este endereco para entrar em contato comigo:
BM-2cWSRwwinrcLGFiTNF5RxiwR8hW5jikS1m@bitmessage.ch . Este metodo funcionara 100%.
4. No e-mail deve incluir o sua identificacao pessoal (id- [REDACTED]).
Em seguida, voce recebera o descodificador e instrucoes.
1. Voce tem 3 dias para pagar meus servicos. Apos esse periodo, voce perdera todos os seus arquivos.
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 .id-%X%_steaveiwalker@india.com_. 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.

What is CryptON Ransomware?

CryptON is a ransomware infection - the malicious software that enters your computer silently and blocks either access to the computer itself or encrypt your files. 

Many ransomware viruses use sophisticated encryption algorithms to make your files inaccessible. The goal of ransomware infections is to demand that you pay a ransom payment to get access to your files back.

What Does CryptON Ransomware Do?

Ransomware in general is a malicious software that is designed to block access to your computer or files until a ransom is paid.

Ransomware viruses can also damage your system, corrupt data and delete files, resulting in the permanent loss of important files.

Another way you may become a victim of CryptON is if you download a fake installer, crack or patch from a low reputation website or if you click on a virus link. Many users report getting a ransomware infection by downloading torrents.

How to Open .CryptON files?

You can't without a decryptor. At this point, the .CryptON files are encrypted. You can only open them once they are decrypted using a specific decryption key for the particular algorithm.

What to Do If a Decryptor Does Not Work?

Do not panic, and backup the files. If a decryptor did not decrypt your .CryptON files successfully, then do not despair, because this virus is still new.

Can I Restore ".CryptON" Files?

Yes, sometimes files can be restored. We have suggested several file recovery methods that could work if you want to restore .CryptON files.

Cyber-security authorities, responsible for handling ransomware attack reports in different regions all over the world:

Germany - Offizielles Portal der deutschen Polizei

United States - IC3 Internet Crime Complaint Centre

United Kingdom - Action Fraud Police

France - Ministère de l'Intérieur

Italy - Polizia Di Stato

Spain - Policía Nacional

What Happens If I Don't Pay Ransom?

If you don't pay the ransom, the hackers may still have access to your computer, data, or files and may continue to threaten to expose or delete them, or even use them to commit cybercrimes. In some cases, they may even continue to demand additional ransom payments.

Can a Ransomware Attack Be Detected?

Yes, ransomware can be detected. Anti-malware software and other advanced security tools can detect ransomware and alert the user when it is present on a machine.

It is important to stay up-to-date on the latest security measures and to keep security software updated to ensure ransomware can be detected and prevented.

Do Ransomware Criminals Get Caught?

Yes, ransomware criminals do get caught. Law enforcement agencies, such as the FBI, Interpol and others have been successful in tracking down and prosecuting ransomware criminals in the US and other countries. As ransomware threats continue to increase, so does the enforcement activity.
