How dangerous is CryptoFortress ransomware?

It seems that developers of the CryptoFortress virus have been inspired by the TorrentLocker ransomware because they have borrowed its ransom note, payment page and some parts of its code. However, researchers found more differences than similarities, so this malware can be called an updated and improved version of the Torrent Locker. For almost two years ransomware has been spreading all around the Internet and taking personal users’ files to hostage. Similarly to other file-encrypting viruses, CryptoFortress ransomware has been created for blackmailing and swindling money from the regular computer users. People, who do not have data backups are the easy target because they feel like someone has stolen their memories and important documents. Therefore, if you haven’t faced ransomware attack yet, you should make data backups right now. Nowadays a number of ransomware attacks are growing rapidly, so it’s important to be prepared for the worst scenario. In case of the attack, you won’t consider paying the ransom; you will simply remove CryptoFortress from the system and use data backups.

On the affected computer malware looks for these 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. Once it finds them, it encrypts them using AES algorithm. CryptoFortress virus appends .frtrss or .ecc file extensions to all encrypted files, so after attack victims can distinguish corrupted files from the safe ones. Following data encryption, ransomware delivers an alert that informs about this unpleasant situation. Cyber criminals demand 1 Bitcoin for data recovery tool. Besides, they want to encourage victims to trust them and decrypt two files (not bigger than 500Kb) for free. However, here we want to stop you. These two files might be the only ones that you would be able to restore. After receiving your payment, developers might disappear. Therefore, if you don’t want to experience money loss, you should concentrate on CryptoFortress removal. Scan computer with Reimage or other reputable anti-malware software, and after automatic removal, use data backups or additional data recovery methods to recover your files. Malware might have failed to delete Shadow Volume Copies, or you might be able to use Windows Previous Versions features to restore corrupted files.
