What is CryptoFortress virus?

Understanding CryptoFortress ransomware virus

CryptoFortress virus [1] is a file-encrypting malware that has been attacking computers and encoding users' personal files since the March 2015. Researchers have revealed that malware is an updated version of TorrentLocker ransomware [2] because it uses the source code for the ransom notes and other web pages from Torrent Locker. It has also been called as a “new generation” ransomware [3] as it can block unmapped network shares as well. Cyber criminals distribute malware via malicious spam emails and infected links, and when the victim clicks on it, malware steps into the system and starts looking for targeted file types (.unity3d, .blob, .wma, .avi, .rar, .DayZProfile, .doc, .odb, .asset, .forge, .cas, .map, .mcgame, .rgss3a, .big, .wotreplay, .xxx, .m3u, .png, .jpeg, .txt, .crt, .x3f, .ai, .eps, .pdf, .lvl, .sis, .gdb). CryptoFortress ransomware uses AES encryption algorithm and appends either .frtrss or .ecc extension to each encoded picture, document, audio or video files. When data encryption is completed, malware delivers a warning message to the victims:

All your important files (such as files on the network disks, USB devices, etc.): photos, videos, documents were encrypted with CryptoFortress virus. The only way to get your files back is to buy our decryption software. Otherwise, your files will be lost.

Caution: Removing of CryptoFortress will not restore access to your encrypted files.

Screenshot of CryptoFortress ransom noteIn this picture, our expert points to a ransom note left by CryptoFortress ransomware virus. Just like any other ransomware virus, CryptoFortress malware is an extortion tool that takes personal files hostage and asks the victim to pay a ransom.

However, you should not let crooks scare you and blackmail you. On the one hand, they tell the truth – CryptoFortress removal will not recover your files. On the other hand, hackers are lying to you about the recovery pf your files because there are other ways to get back access to the lost data. However, in the ransom message hackers included links that lead to the official website and urge to send a certain amount to a particular address and then to transmit a transaction ID to validate the payment. The developers of CryptoFortress have been demanding 1 Bitcoin (about $300), but before transferring the ransom, victims can decrypt two files that are up to the size of 500 Kb for free. Of course, you can panic and fall for paying the ransom. However, don't be surprised after you lose not only the data from your PC but also money from the bank account. To prevent this from happening, make sure that you remove CryptoFortress virus from the system as soon as possible using ReimageIntego or SpyHunter 5Combo Cleaner. Then you can try to restore your files from backups or use additional data recovery methods.

How can this ransomware step in my PC?

CryptoFortress malware can enter your PC system similarly to other ransomware [4], such as TeslaCrypt, CryptoDefense, SynoLocker, and many others. Usually, the virus spreads via spam emails, fake update alerts, infected links and similar means. By the way, P2P networks may also be involved in the distribution of this virus. To protect your computer from being infected, we highly recommend you to install a reputable anti-spyware and keep it up-to-date. Besides, you should stay away from suspicious email attachments and links. Before opening them, you have to double check the sender and information which is added to the message. You should always look for typo or grammar mistakes to protect yourself from malicious emails. [5] Finally, make sure you keep your important data in the safe place, e.g. external hard drives and USB sticks.

CryptoFortress removal guidelines

Ransomware viruses are one of the most dangerous and complicated computer infections, so their removal is not easy as well. For CryptoFortress removal you have to employ professional anti-malware program, for instance, ReimageIntego or SpyHunter 5Combo Cleaner. However, if malware does not allow you to install or update security tools, you should reboot your computer with a Safe Mode with Networking and follow the steps presented at the end of the article. Unfortunately, it’s not enough to remove CryptoFortress virus from the PC to get back access to your files. For that, you will need other tools or data backups. Data recovery options are provided below. In the future, you should think about the immunity of your personal data in advance. We highly recommend you to use USB external hard drives, CDs, DVDs, or simply rely on online backups, such as Google Drive, Dropbox, Flickr and other solutions.

Bonus: Recover your data

Guide which is presented above is supposed to help you remove CryptoFortress from your computer. To recover your encrypted files, we recommend using a detailed guide prepared by 2-spyware.com security experts.

Before thinking about data recovery, you have to remove CryptoFortress virus from the computer. Otherwise, ransomware can encrypt your files one more time. When your computer is clean from viruses, you can plug in external device where you keep data backups and copy them. If you do not have data backups, you can try additional data recovery options presented below. Keep in mind that these solutions may not recover all your files; however, some of the importannt ones should be decrypted.

If your files are encrypted by CryptoFortress, you can use several methods to restore them:

Restore your files with Data Recovery Pro

Data Recovery Pro is a professional tool that allows automatically restore accidentally deleted or encrypted files. Many computer users, who had dealt with data recovery after ransomware attack, claimed that this tool helped them to restore the majority of the corrupted files.

  • Launch it and scan your computer for files encrypted by CryptoFortress ransomware;
  • Restore them.

Take advantage of Windows Previous Versions feature

This method allows traveling back in time and getting back the latest saved version of the encrypted files. However, you should know that this method cannot restore all files encrypted by CryptoFortress ransomware. It allows restoring only individual files. Besides, this method will work only if you have enabled System Restore function before ransomware attack.

  • Find an encrypted file you need to restore and right-click on it;
  • Select “Properties” and go to “Previous versions” tab;
  • Here, check each of available copies of the file in “Folder versions”. You should select the version you want to recover and click “Restore”.

  • Right-click on the folder you want to restore and select “Export”. You can also select where you want it to be stored.

Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from CryptoFortress and other ransomwares, use a reputable anti-spyware, such as ReimageIntego, SpyHunter 5Combo Cleaner or Malwarebytes

How to prevent from getting ransomware

Do not let government spy on you

The government has many issues in regards to tracking users' data and spying on citizens, so you should take this into consideration and learn more about shady information gathering practices. Avoid any unwanted government tracking or spying by going totally anonymous on the internet. 

You can choose a different location when you go online and access any material you want without particular content restrictions. You can easily enjoy internet connection without any risks of being hacked by using Private Internet Access VPN.

Control the information that can be accessed by government any other unwanted party and surf online without being spied on. Even if you are not involved in illegal activities or trust your selection of services, platforms, be suspicious for your own security and take precautionary measures by using the VPN service.

Backup files for the later use, in case of the malware attack

Computer users can suffer from data losses due to cyber infections or their own faulty doings. Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact – you can set this process to be performed automatically.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use Data Recovery Pro for the data restoration process.
