CY3 ransomware (.CY3 file virus) Removal

CY3 Ransomware is a variant of the Dharma family. It encrypts files on the host computer and renames them by adding victim’s ID, attackers’ email address, followed by “.CY3” file virus extension.

For an instance, a file named “myphoto.jpg” will get converted into “myphoto.jpg.id-9ECFA84E.[cybercrypt@tutanota.com].CY3” after the attack. You will be unable to access any of your files and find “info.txt” ransom note on your PC.

The note contains warning messages and ransom demands with attacker’s email address. This nasty virus demands a hefty extortion fee for the decryption key. This guide can help you remove this virus and decrypt your files without paying money to hackers.

Threats like CY3 File Virus keep getting back on the PC if all associated files are not removed. So you are advised to use a powerful Malware Removal Tool to run a thorough scan of your PC and delete all threats at once.

What is CY3 Ransomware

CY3 Ransomware is a data locker malware also known as a cryptovirus. This type of threat is used to encrypt files on targeted PC and extort money from victims to restore files. This type of malware attack has gotten a significant rise in recent years. People are more vulnerable to such infections because they store valuable data on their computers.

Ransomware creators know this fact and take the advantage of such a situation to make an illegal profit online. This dangerous malware can lock all types of files such as videos, images, audio, documents, database, backups, and so on. If your computer got infected by this nasty virus, then you must not engage in any conversation or negotiation with hackers. Actually, the primary motive of CY3 File virus is to restrict users from accessing any of their files.

A ransom note is also left on the victim’s computer to ask for the money in return for unlocking the documents. But taking cyber criminals at their word could be dangerous, as many people got scammed and could not get their files back. You need to remove CY3 Ransomware from your PC and recover your files through alternate methods. Read this guide for detailed information about this file-encrypting malware, how to remove it and how to decrypt your files.

More about CY3 File Virus

CY3 ransomware is a notorious file-encrypting malware that belongs to DHARMA virus family. This dubious threat is created by hackers with the ambition to fraud money from users by blackmailing them. This new variant of the data locker virus can encrypt all your files without your permission using a powerful cryptography algorithm.

This virus is able to infect any version of Windows PC easily and it can sneak past your antivirus protection without detection. Earlier you won’t even recognize what struck your PC and then suddenly all your files are locked with an undecipherable key.

CY3 File Virus Ransomware

CY3 File Virus is one of the many variants released by the creators of the Dharma Ransomware virus. This dubious malware intrudes on your computer and then executes its malicious encryption software. This nasty Ransomware has created this ugly situation on your computer so that it can force you into paying the ransom money for the decryption key.

What happens to your files

As you know, CY3 Ransomware uses a powerful RSA military-grade encryption algorithm to encode your files. All your files will still be there on your computer, but you will not be able to access them. This kind of encryption algorithm is mainly used to protect files, and transmit information without the tension of anyone intercepting the message. This practice was first used for military and intelligence purposes but now many social media companies like WhatsApp, Viber, Telegram, and others are using end-to-end encryption. This technology keeps all communication safe from sender to receiver and no one can read the messages.

Such end-to-end encryption and military-grade cipher are good for privacy but in hackers’ hands, it is a weapons of mass destruction. There is no way to break the encryption without a decoder and thus cybercrooks behind CY3 Ransomware get away by cheating innocent users. All these files encrypted by this malware can only be decoded by a private decryption tool and key which is unique for every computer. Brute forcing to restore files to the original version might corrupt the whole and even the decryption tool won’t even recover .CY3 virus files.

However, there are some ways to recover files infected by this virus. It will not be easy but it could be possible to recover most (if not all) of the files without paying money to hackers. Sometimes ransomware creators also leave some flaws which could be exploited to create a decryptor. Unfortunately, there is no free decryptor yet found for CY3 Ransomware. But it does not mean it’s not going to happen, however, it may take time. You can also recover your files through backup or use data recovery software to recover previous versions of your encrypted files.

Do not pay money hackers

Paying ransom money to hackers to get the decryption is not a good idea. Many people might think they cannot risk their valuable information and that paying money is the easy way out but it can be dangerous. As you know, CY3 File Virus is a variant of Dharma Ransomware. There are hundreds of more variants just like this. So if you once pay, your system can get infected again by some other version of the malware. It is also possible that some other completely ransomware virus attacks your PC. Because once your system gets infected, a loophole gets created which can be used by viruses to intrude on your machine.

It is also very much possible that after getting money, the creators of CY3 Ransomware will stop responding to your emails. Many of the victims already reported such incidents and there is no way to find the hackers. Payment is also in Bitcoins which cannot be traced and so you can lose both your files and money. Firstly, the main thing is you cannot trust cyber criminals to keep their word once they get paid, and secondly, you cannot force them to. So in our expert opinion, you must refrain from paying any money to the attackers. It will only motivate them to expand their blackmailing business.

Distribution methods used to transmit ransomware

Most of the users ask us how their system got infected in the first place. They have no clue about the infection whatsoever. So if you are thinking the same question then you need to know that hackers use several tricks to spread their creations. Threats like CY3 Ransomware are mostly spread through illegal or pirated software downloads. When you go looking for cracked programs, how do you think they spoof the purchased software for free? Trojan viruses are used to crack software, and when you install such programs, that Trojan can always drop new threats on your PC.

Spam email campaigns are another very famous and effective method used by hackers to spread viruses like CY3 File Virus. Hackers use software to send bulk messages with fake content and malicious attachments. Bulk messaging practically costs nothing, but even if 1 victim out of 1000 pays the ransom money, it’s still a good profit. Many freeware creators allow bundled programs that get installed in the background without permission. Such bundled apps can trigger the installation of malware and users won’t even know.

Browsing torrent or porn sites causes too much redirection. You mostly land on suspicious sites with various fake ads, promo, alerts, warnings, etc. that ask you to click. Once you click on those ads, a malicious script could trigger the download and installation of malware on your system. Sharing files on an unsafe network could also bring threats like this to your computer. We have made a list of precautionary measures to avoid malware attacks on your PC which is in the last of this guide. Make sure to read those tips to protect your system in the future.

Removal of virus and Decryption of files

If you want to recover your files, then you must remove CY3 File Virus completely from your PC. Removing this virus manually may not be easy, so you are advised to use a powerful Malware Removal Tool to get rid of this threat completely. Do not format your PC or re-install Windows, because you will not be able to recover files then. To restore your encrypted files, you can use the backup copies if you have made any. If you don’t have a backup then try using Data recovery software. If you try to restore files without removing viruses, then it will keep encrypting your data. So it is advised to delete this Virus completely from your machine.
