How to remove SunCrypt Ransomware and decrypt .sun files

What is SunCrypt Ransomware

Sun or SunCrypt is classified as cryptovirus attacking systems to encrypt personal data. It started its journey in October 2019 and continues its presence infecting users until these days. The moment SunCrypt can be spotted in your PC is when it changes your files by adding the .sun extension. It was also heard about another version of SunCrypt which applies a string of random symbols instead of extensions. A change to something like this 1.mp4.sun or 1.mp4.G4D3519X58293C283957013M35DC8A2V0748D9845E7A5DBD6590E3F834C4638 means you are no longer allowed to access your data. To recover it back, SunCrypt creates a text note (DECRYPT_INFORMATION.html or YOUR_FILES_ARE_ENCRYPTED.HTML) that contain ransom instructions.

Although SunCrypt is mainly oriented towards English-speaking users, you have a possibility to switch between German, French, and Spanish as well. This by far increases the traffic of victims allowing developers to extend their business. As stated in the note, victims have to install the Tor browser and click on the “Go to our website” to purchase the decryption software. The required fee may vary based on the individual case, however, no matter how low or high it is, we recommend against going for such a risk. Statistically, extortionists tend to fool users and not send any tools, even after making a payment. Recovering data on your own is often close to impossible. It may be feasible in case there are some flaws or bugs inside of a virus. In other situations, the only way is using a backup copy, if one was created before the infection. Whatever the case, you must delete SunCrypt Ransomware from your system to prevent further encryption of data, so follow our tutorial below.

How SunCrypt infected your computer

Thousands of cases indicate on e-mail spam being the most popular distribution channel. It is used by extortionists to send messages bundled with malicious attachments (MS Office documents, PDFs, executables, and JavaScript files). The content is often represented as something legitimate meant to remove doubts from potential victims. Then, once the trick has worked itself out and users decide to open a file, the infection gets launched and contaminates systems in the background mode. As you might already know, the consequences of such actions may be fatal for your data, so keep an eye on that in the future. Other methods of ransomware distribution also exist. These are botnets, keyloggers, trojans, fake software updates, or cracking tools, by hacking unprotected RDP configuration, and so forth. Remember that all infections come from the unattentiveness of users, so make sure you are careful when using the web.
