Saturn ransomware (Removal Instructions) - updated Feb 2018

What is Saturn ransomware?

Saturn ransomware encrypts personal data and urges victims to pay for the decryptor

Saturn ransomware is a file-encrypting virus that usually spreads via malspam campaigns, encrypts personal files, and appends .saturn file extension to each of them. The ransomware operates as a Ransomware-as-a-Service (RaaS),^[1] which means that anyone who wants to distribute it can do that by simply signing in as a volunteer on a specific domain via Tor. When all targeted files are locked, Saturn ransomware generates five ransom notes, which are installed in folders with the locked files and named as follows:

• DECRYPT_MY_FILES#.html,
• #DECRYPT_MY_FILES#.txt,
• #KEY-[id].KEY,
• #DECRYPT_MY_FILES#.vbs,
• #DECRYPT_MY_FILES.BMP.

The first task that the virus does on the affected system is checking if the computer runs in a virtual environment. If it does, malware starts its hazardous task; if not – it won’t start data encryption. Saturn ransomware uses AES cryptography to append an unbreakable file extension to the targeted files. It targets for image, audio, and video files, databases, and other popular files to cause as much damage as possible to ensure that the victim fall for paying $300 ransom.

Besides, Saturn malware is designed to delete Shadow Volume Copies, disable Windows startup repair, and clean Windows backup catalog. All these tasks prevent users from data recovery. Hence hackers’ chances to collect ransoms become higher. However, security experts warn not to follow the instructions provided in the above-mentioned files and do not pay the ransom. Any support for hackers will induce them to initiate further crimes, so soon after paying your files may be encrypted with another Saturn ransomware variant.

Following the successful data encryption, malware delivers ransom notes in DECRYPT_MY_FILES#.html and #DECRYPT_MY_FILES#.txt files. Here crooks provide brief information what victims have to do. The first step is to install Tor Browser and access provided an address where users will find more information:

Additionally, Saturn ransomware virus drops a key file called #KEY-[id].KEY in each folder that contains encrypted files. This key gives access to the TOR^[2] payment website. Users have to upload it, confirm provided code on the screen and pay the ransom in Bitcoins.

Victims are asked to pay $300 in Bitcoins withing seven days. After the deadline, the size of the ransom doubles. However, as soon as the payment is confirmed, users will be able to download and use Saturn Decryptor. Unfortunately, there's no proof that the decryption is functional.

Additionally, the Saturn file-encrypting virus also drops a #DECRYPT_MY_FILES#.vbs which is an audio file that informs about ransomware attack. Malware also changes a new computer’s background picture where criminals provide the same information as in the ransom note.

Security experts do not recommend paying the ransom because this may lead to money loss only. Crooks might blackmail you into paying more than a few hundreds of dollars. Therefore, you’d better invest this money in great backup solution and remove Saturn ransomware from the computer.

For Saturn virus removal, we recommend using professional anti-malware software like FortectIntego, SpyHunter 5Combo Cleaner or [3]. These tools can not only eliminate ransomware but clean the damage which was done to Windows registry and other system's components.

Anyone who want to join criminals can create a new version of this ransomware. Saturn raas or Ransomware-as-a-Service have been found promoted on the black market allowing all volunteers to generate revenue from this illegal business. In comparison to other RaaS, Saturn ransomware works as an affiliate program, so people don't have to pay for it.

People who are interested in this business model only need to sing up on a specific website on the Dark Web and obtain a virus. Malware is ready to use. Thus, people can start it spreading immediately.

Developers of the Saturn virus take 30% of the ransoms collected by those who decided to participate in this RaaS affiliate program. Therefore, crooks let hacker-wannabes to keep 70% of the collected ransoms.

Saturn ransomware virus asks to pay $300 for data recovery in seven days.

Distribution methods of the crypto-malware

Malicious spam emails and malvertising are the main methods how this malicious program can get into your PC. There’s no doubt that crooks might rely on other strategies too, such as drive-by downloads or exploit kits.

However, users are advised to be extremely careful with received emails. Malicious email attachments are the main ways how ransomware payload is dropped on the system. Hence, security experts from NoVirus.uk^[3] remind not to rush opening receive documents. Always make sure that you can trust the sender and check the file with online scanners.

Additionally, you should avoid clicking suspicious adds, downloading unknown programs or installing software updates that arrive in the form of pop-ups. Most of the time they cover malicious content.
