CY3 Virus – Why Is My Windows Infected?

CY3 Ransomware Virus is a malicious computer virus that can infect your Windows system using obfuscators and encrypt your files, making them inaccessible unless you pay a ransom. It is important to be aware of this threat and take steps to protect your system from it. Taking regular backups of your important data can help you recover from an attack and get your system back up and running quickly.

CY3 Virus – How Did I Get Infected?

The CY3 virus is typically spread through malicious software downloads or infected emails:

  • If it is sent to you as an e-mail attachment or a URL.
  • By being downloaded from a shady site.

It is important to practice safe browsing and downloading habits to protect your computer from becoming infected with the virus.

CY3 Virus – What Does It Do?

After infection, the CY3 Virus displays a ransom note demanding payment in order to decrypt the files. It also adds an extension to the encrypted files, which can be used to identify the ransomware. The ransom amount is usually in the form of cryptocurrency, such as Bitcoin.

Upon infection, the CY3 virus drops its own payload files that may be in the following directories:

  • %Local%
  • %Temp%
  • %Windows%
  • %SystemDrive%
  • %LocalLow%
  • %AppData%
  • %System%
  • %system32%

Then it leaves the following ransom note:

All your files have been encrypted!
Don’t worry, you can return all your files!
If you want to restore them, write to the mail: ronrivest@airmail.cc YOUR ID –
If you have not answered by mail within 12 hours, write to us by another mail:ronrivest@tuta.io
Free decryption as guarantee
Before paying you can send us up to 3 files for free decryption. The total size of files must be less than 3Mb (non archived), and files should not contain valuable information. (databases,backups, large excel sheets, etc.)
How to obtain Bitcoins
The easiest way to buy bitcoins is LocalBitcoins site. You have to register, click ‘Buy bitcoins’, and select the seller by payment method and price.

Also you can find other places to buy Bitcoins and beginners guide here:
hxxp://www.coindesk.com/information/how-can-i-buy-bitcoins/
Attention!
Do not rename encrypted files.
Do not try to decrypt your data using third party software, it may cause permanent data loss.
Decryption of your files with the help of third parties may cause increased price (they add their fee to our) or you can become a victim of a scam.

In addition to it, the virus also leaves an info.txt file, containing the following message:

all your data has been locked us
You want to return?
write email jerd@420blaze.it or cybercrypt@tutanota.com

Additionally, this virus may also set up value entries in some specific Registries in Windows.

It is important to note that paying the ransom does not guarantee that the files will be decrypted. Additionally, paying the ransom encourages the attacker to continue their malicious activities as they can make money in return. Therefore, it is advised to take preventive measures such as using a reputable antivirus software and backing up files to prevent infections.

What Are .CY3 Files

The .CY3 files are a type of file which has been encrypted using its own cipher. This type of encryption is used to protect sensitive data or documents from unauthorized access. The algorithm works by scrambling the file contents, making them unreadable to anyone who does not have the correct decryption key.

The .CY3 virus may target the following files to encrypt them:

  • Videos (.mp4, .avi, etc.).
  • Audio (.mp3, .wav, etc.).
  • Picture file kinds (.jpg, .png, .etc).
  • Archive file formats (.zip, .rar, etc).
  • Documents of different types (.docx, .pptx, etc.).
  • Others.

After encryption, the files begin to look like the following:

How to Open .CY3 Files

Opening .CY3 encrypted files by ransomware can be done by using a ransomware decryptor. A ransomware decryptor is a tool designed to decrypt files that have been locked by ransomware. These tools usually work by scanning the infected computer for encrypted files, then attempting to decrypt them using various methods, such as brute-force attacks, dictionary attacks, and known-plaintext attacks. If the ransomware decryptor is successful, then the encrypted files can be opened and used. It is important to note, however, that in order to use the ransomware decryptor, you need to have an idea of what ransomware was used to lock the files in the first place.

What To Do If My Files Are .CY3?

If your files have been encrypted with the .CY3 extension by ransomware, the first step is to immediately disconnect the infected system from any other networked device or the internet. You should then take steps to back up any essential data stored on the device. Unfortunately, there is no guaranteed way to restore the files that have been encrypted, as ransomware is designed to make them unrecoverable. However, you may be able to restore the files from a backup or by using a third-party decryption tool. It is also important to remove any malicious software that may have caused the ransomware attack, such as by using an anti-malware program.

How To Protect Windows from CY3 In The Future?

To learn how you can protect yourself from ransomware, like CY3, we advise to read on how to safely store your files to protect them from ransomware.

How to Remove CY3 Ransomware Virus?

Removing the CY3 ransomware virus is an important step in securing your computer and data. The best way to do this is by using an anti-malware program to scan for the ransomware and remove it. It will help detect and remove any malicious files or programs related to the ransomware.

Finally, you should also consider restoring your system to the most recent backed up version prior to the infection. This should help ensure that all of your data and files are restored safely and securely.
