0day Ransomware

What is 0day Ransomware?

If you do not take care of your operating system, 0day Ransomware could slither in and destroy your personal files. Although this infection does not remove them, it locks them up. The threat encrypts them using a unique encryption key, and, as a result of that, the files cannot be read. Unfortunately, only a unique decryption key can “unlock” your files, and we cannot provide you with it. A free decryptor that would work did not exist at the time of research either. If you find a tool that claims to restore your files, make sure you research it first because you do not want to let in more threats by accident. All in all, the only ones who appear to have the decryptor are the creators of the infection, and they are unlikely to let it go, even if you agree to all of their conditions. We talk more about that in this report. Of course, we want to focus on deleting 0day Ransomware, and if you too want to eliminate this malware from your Windows operating system, please continue reading.

How does 0day Ransomware work?

Anti-Spyware-101.com research team informs that 0day Ransomware is part of the Dharma (also known as Crysis) family, to which many different infections belong to. Some of them are Dharma Ransomware (.bkpx extension), helpfilerestore@india.com Ransomware, and Darknes@420blaze.it Ransomware. For the most part, these infections work the same, but their creators use unique email address and file extensions. 0day Ransomware adds the “.id-[ID].[my0day@aol.com].0day” extension to all of the files it corrupts, and even though it is easy to remove this extension, the files cannot be restored by doing that. The encryption of files is performed silently after dropping the infection and executing it silently as well. Most likely, spam emails or remote access vulnerabilities are used for the distribution of this threat and its clones. After encryption, there is no point for the attackers to keep the infection concealed, and they use a file named “RETURN FILES.txt” to help the victims realize what has happened. It appears that the file should be created on the Desktop, but if you find copies, do not forget to delete them as well.

The message inside the TXT file created by 0day Ransomware is extremely vague. It declares that files were encrypted, and then it instructs to email my0day@aol.com or daysupp@aol.com to have the files “returned.” If you are not familiar with ransomware, this message might make no sense, but you might see no harm in sending a quick message. Unfortunately, you could be opening a security backdoor by sending that message because once the attackers know your email address, they can send you whatever they want. Initially, however, they should send a request for you to pay a ransom in return for a decryptor. As we mentioned already, paying however much the attackers request is not a good idea because they are unlikely to give you the decryptor in return anyway. We hope that all of your personal files were backed up before the attack, and you do not need to recover the original files because you have backup copies as a replacement.

How to delete 0day Ransomware

It is crucial to keep the Windows operating system protected at all times, and that means that you need to install all updates, employ reliable security software, and, of course, be mindful about your own actions. If you are not careful, 0day Ransomware or some other malicious threat could invade it, and then your files could be lost. Although restoring the encrypted files was not possible at the time of research, if backups exist, you do not need to worry about decryption at all. If you were not prepared, make sure you start backing up files to secure them in the future. To remove 0day Ransomware, you can either choose to employ an anti-malware program, or you can handle the operation on your own. Since identifying and deleting the threat’s launcher file is an expert-level task, we recommend trusting an anti-malware program. As you know now, having your system protected is important if you want to avoid ransomware in the future, and so it is high time you installed reliable anti-malware software anyway.
