Hentai Onichan Ransomware Removal Guide

Hentai Onichan Ransomware is a file encryptor, which means that it applies a unique encryption key to make you unable to read your files normally. At the time of research, free decryptors that could read the files corrupted by this malware did not exist, and so if you find an offer for a tool that, allegedly, can restore files, please make sure that you are being careful. Of course, you should not pay attention to the cybercriminals’ promises to provide you with a “personal decryption key” if you fulfill their demands. The infection was created to make you make a payment, but there are no guarantees that you would be given anything in exchange for it. Unfortunately, that is how malware works. The recommendation from our malware experts is that you delete Hentai Onichan Ransomware immediately, but of course, if your personal files were encrypted, you might be worried about restoring them first. Hopefully, there is another way for you to get your files back so that you could perform removal ASAP.

Hentai Onichan Ransomware appends the “.hor” extension to the files it encrypts. That is something that most file encryptors do, including Rezm Ransomware, Topi Ransomware, or MOOL Ransomware. All of them rely on security backdoors and system vulnerabilities to invade operating systems. Do you remember opening spam emails and their attachments or downloading new files and software before the attack of Hentai Onichan Ransomware? If you do, you might have no one else to blame but yourself for the invasion of this malware. Once it is executed, it should create files in %APPDATA%\Microsoft\Windows\Start Menu\Programs\Startup, and the names of these files might be completely misleading. For example, they could be named “firefox.exe” or “opera32.exe,” which are normally the names of legitimate, harmless files. The infection encrypts files immediately after execution, and it is only interested in personal files. Obviously, if you do not have backups/copies of your documents, videos, photos, or other types of files, this dangerous infection can be extremely damaging. This is why we always recommend creating backups.

If Hentai Onichan Ransomware has encrypted your files, you must have discovered the ransom note file named “HELP_ME_RECOVER_MY_FILES.txt” already. Copies of this file should be placed everywhere where encrypted files are. The main message of the ransom note is that you must pay a ransom of 30 BTC – which is over 200,000 USD – to the attackers’ wallet (1ErGqSg86nW2kEH6dFwe217SNSCdcwWJQ7) and then send proof of the payment along with a unique ID code to hentai.onichan.key@protonmail.ch. If you do this, you are unlikely to get anything in return. If you email the attackers to try to plead with them, you are unlikely to achieve anything. Even if they bring the ransom down, you are unlikely to get a decryption password in return. All in all, because the ransom is so incredibly big and because the attackers’ wallet is completely empty, we are guessing that this malware is not going to be spread far and wide. Hopefully, it will disappear into the abyss sooner rather than later.

If Hentai Onichan Ransomware encrypted your files, we hope that you have backups/copies stored somewhere safe. If you do, you should be able to replace the corrupted files as soon as you delete the threat. Perhaps you do not even need to do much to eliminate this malware because it should automatically remove itself after execution and encryption. Of course, just in case leftovers could remain active, we advise implementing a malware scanner if you decide to proceed with manual removal. The best thing you can do, of course, is install a trusted anti-malware program that could automatically scan your system and remove Hentai Onichan Ransomware leftovers, and, at the same time, secure your Windows operating system. Remember that as long as it remains unprotected, it will remain vulnerable to malware. Also, note that even if you secure your system, you must not forget to always create copies of files just to be safe.
