How to Remove Cypress Ransomware

What is Ransomware?

Ransomware is malicious software that restricts access to data or sometimes computer systems until a ransom is paid. Ransomware has been compared to other types of malware, such as Trojan horses, viruses, and worms. Ransomware can cover multiple platforms, including Windows, Android, and iOS.

How Does Ransomware Spread?

Ransomware can spread in many different ways, and it is hard to know exactly which network is being targeted. Ransomware has the power to propagate through networks and system vulnerabilities, removable drives, email attachments, as well as social media platforms like Facebook. Hackers can also install it by tricking users into clicking on a malicious link or download button that does not appear harmful at first glance but installs ransomware onto the device once opened.

How Does Cypress Ransomware Work?

Cypress Ransomware uses the AES 256 bit encryption to encrypt all files on the device. Cypress Ransomware uses a hard-coded key generated when the malware is first installed on the system. The malware does not use any other encryption methods to encrypt its data during execution.

The virus can perform the encryption by using a certain command called "encrypt," which Cypress Ransomware executes at runtime, and also prevents users from accessing their files with default tools such as "Msys," "WinRAR," and "7Zip".

It then displays a ransom note, which states that only specific programs or software will allow access to users' files.

How to Remove Cypress Ransomware

Once the ransomware is executed, and a window pops up, the user needs to close this window immediately without opening the note. The user should then reboot their device and scan it for malware using a security software package.

The user should then make sure they have backed-up all of their files before proceeding with any further steps. Once all files are backed up, the user can safely remove any ransomware from their devices by disconnecting them from your network or computer system to ensure no other devices are infected.

To remove Cypress Ransomware, you will need to boot into Safe Mode on Windows 8 or 10 to stop Cypress Ransomware from automatically executing on startup by rerunning it after rebooting your computer.

Once your files are backed up, we recommend you back up the encrypted files to an external hard drive so that you can revert to those if needed.

If the ransomware prevents you from using other software tools such as "WinRAR" or "7zip", you should use a new computer to restore your files without installing any of these programs. This way, the malware will not be loaded on the new machine, and it will allow for full restoration of the original files.
