Gefest 3.0 ransomware – a file locking threat which adds the .GEFEST extension to mark encrypted data

Gefest ransomware
Gefest virus - ransomware which uses RSA encryption to lock up data

Gefest ransomware, also known as Gefest 3.0 ransomware, is another file encrypting infection which appears to belong to the Scarab family. The virus is using the RSA-2048 algorithm[1] to lock up all documents that are stored on the infected device. Once the files become unavailable, the ransomware generates a ransom message named HOW TO RECOVER ENCRYPTED FILES.txt in which crooks are urging their victims to pay a ransom in exchange for the decryption key[2] which is needed to recover encrypted files. The ransom needs to be paid in Bitcoin and the price depends on how fast the victims contact virus developers via mrpeterson@cock.li or debora2019@airmail.cc email addresses. In most of the cases, victims get infected via open_me.txt or similar files which are typically sent to their email inbox. However, contacting with Gefest 3.0 ransomware developers is not recommended as you can get scammed or face other unwanted consequences such as permanent data loss, other malware injection, etc.

Once inside the system, Gefest virus makes needed changes. Ransomware viruses, including this one, might alter the registry, drop its own files, and even disable your anti-virus software. Additionally, some of these cyber threats might be capable of erasing files' Shadow Volume Copies and making their recovery even more complicated. To prevent such changes, make sure you are very careful while dealing with emails from unknown senders. More about the prevention of ransomware can be found in the second part of this guide.

After encrypting files, Gefest 3.0 provides this type of message:

Talking about the ransom price, criminals often demand a ransom which needs to be paid in a well-known cryptocurrency (mostly, Bitcoin). However, these people are urging for such conditions not without a reason. Cryptocurrency transfers do not require any personal information, so, that means all operations remain untrackable and safe. 

Even though you might be scared by the permanent loss of your files, do not rush to pay the ransom for the crooks. These people are very likely not to fulfill their promises and, as a result, you might experience unnecessary money loss. What you should do is remove Gefest 3.0 ransomware from the system right after you find its first signs. Use Reimage to detect all malware-laden components on your computer.

After you deal with the Gefest 3.0 ransomware removal, you can start thinking about possible data recovery methods. Even though no original decryptor has been released yet, you can definitely give other tools a try! We have provided some third-party software which you can find below the article. Make sure to pick the right method and you might succeed. 

File-encryption can happen after downloading an infected file from the misleading spam email

According to computer experts from NoVirus.uk,[3] if you have caught a ransomware[4] infection recently, there might be more than one way how this cyber threat has invaded the system. However, the most popular ransomware distribution technique is email spam and infected attachments that come clipped to these questionable-looking messages.

Opening the attached files or entering the inserted link might cause you a lot of problems. This way you might easily execute the virus-related content and inject ransomware straight into the system unknowingly. Always be careful while opening your inbox, identify the sender, check for grammar mistakes, evaluate the risk, and just then decide.

Moreover, you should avoid various Internet sites which might lack protection and seem unsafe. Do not click on any suspicious links that might secretly install unpleasant apps or malware. Additionally, we recommend downloading a reputable computer security tool to secure the system fully. Also, you will be able to perform regular system scans with the automatical software and find out if there are any troubles in the system.

Make Gefest 3.0 ransomware vanish from your device and systems

To remove Gefest 3.0 virus, you will need to download and install reliable antimalware. Do not try opting for manual removal as you can easily delete useful system components. To detect all malicious files, use a reputable program such as Reimage or Malwarebytes MalwarebytesCombo Cleaner. Remember, you need to disable the malicious activity before you carry out any data recovery steps because the virus can attack your files right after rebooting the system.

After the Gefest ransomware removal is completed, you can try restoring your entire computer system. For that, proceed with file recovery techniques displayed below this article. Note that the easiest way to recover encrypted files is to use backups. However, if you don't have such, there are still better options than contacting the crooks and facing unwanted money loss.

To avoid getting infected with a virus such as Gefest 3.0 ransomware in the future, make sure you are careful with emails from unknown senders, illegal software and questionable links. Moreover, you need to take care of your files and valuable data properly: store all important files in a USB Flash Drive[5] or on an iCloud server. This way the data will be kept out of reach from anyone else except you.
