What is FilesLocker v2.0?

FilesLocker v2.0 (also known as FilesLocker RANSOMWARE v2.0) is a computer infection designed to render data unusable by encryption. Discovered by MalwareHunterTeam, this ransomware-type virus is a new (updated) version of FilesLocker. Once files are encrypted, they are renamed by adding the ".[]" extension. For example, "sample.jpg" is renamed to "sample.jpg.[]", and so on. FilesLocker v2.0 also changes the desktop wallpaper and places two ransom-demand messages (text files called "#DECRYPT MY FILES#.txt" and "#解密我的文件#.txt") on the desktop itself. It also displays a ransom-demand pop-up window.

According to the information provided on FilesLocker v2.0 ransomware's wallpaper (in English and Chinese), all of the victim's files have been encrypted and more details can be found in the "#DECRYPT MY FILES#.txt" or "#解密我的文件#.txt" text files (ransom notes). These files contain information regarding cost of decryption and how to proceed with the decryption process. The displayed pop-up window states that all files (including photos, videos, documents, music, and so on) have been encrypted and only FilesLocker v2.0 developers can decrypt them or provide victims with a decryption key. They also warn victims that attempts to decrypt files using any third party tools will result in data loss/corruption. They also offer free decryption of three files as proof that they can be trusted and are capable of decrypting the locked files. To decrypt their remaining files, victims must pay cyber criminals .15 of a Bitcoin (currently equivalent to ~$590) to the payment address provided. The message in the pop-up window can only be shown only in English and Chinese - the remaining 12 available languages do not work. It is likely that FilesLocker v2.0 developers are the only people who can provide decryption keys, since most of these cyber criminals use cryptography algorithms (symmetric or asymmetric) that generate unique keys and they store them on remote servers (accessible only by them). In any case, cyber criminals cannot be trusted. They often ignore victims and provide no decryption tools or keys, even if ransoms are paid. As there is no tool capable of cracking FilesLocker v2.0 encryption, the only free solution is to use a backup (if available) and to restore files from there.

There are many examples of other similar ransomware-type viruses, including GandCrab 5.0.9, CmdRansomware, and Risk. Most serve an identical purpose: to encrypt files stored on victims' computers and keep them locked until ransom demands are met. These infections sometimes differ in terms of ransom cost and cryptography (symmetric or asymmetric) used for data encryption. Unfortunately, decryption without involvement of ransomware developers is impossible, unless the virus contains bugs, flaws or is not fully developed. The best way to avoid data loss is to maintain regular backups and store them on a remote server or unplugged storage device.

How did ransomware infect my computer?

It is not clear exactly how FilesLocker v2.0 developers proliferate this ransomware-type virus, however, most cyber criminals proliferate these infections using spam email campaigns, untrustworthy third party software download sources, fake software updaters, or trojans. Spam campaigns proliferate viruses through email attachments (or web links). Generally, these are malicious/infected Microsoft Office documents, archive files (such as RAR), PDF, executable (.exe) files, and so on. Once download and opened, these attachments (or links) install viruses. Untrustworthy third party software download sources (such as peer-to-peer networks, free file hosting, freeware download websites, etc.) are used to trick people into installing viruses. This is achieved by presenting malicious executables (or other files) as legitimate. Various unofficial websites and fake software updaters are also used to proliferate viruses. These updaters install viruses rather than the promised updates or exploit outdated software bugs/flaws .

How to protect yourself from ransomware infections?

To keep your computer safe, browse the Internet, install, download, and update software with care. Be careful with email attachments (or links) received from unknown, untrustworthy, suspicious email addresses. Do not open the presented files (or links) that are attached to irrelevant emails. Update your software using implemented functions (or tools) provided by official developers only. Never use third party/unofficial tools. Furthermore, download software using official and trustworthy sources. Bear in mind that download or installation set-ups often contain rogue applications that often cause high-risk computer infections (including ransomware). Finally, have reputable anti-spyware or anti-virus software installed and keep it enabled at all times. If your computer is already infected with FilesLocker v2.0, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

select a restore point

6. In the opened window, click "Yes".

run system restore

7. After restoring your computer to a previous date, download and scan your PC with recommended malware removal software to eliminate any remaining FilesLocker v2.0 ransomware files.

To restore individual files encrypted by this ransomware, try using Windows Previous Versions feature. This method is only effective if the System Restore function was enabled on an infected operating system. Note that some variants of FilesLocker v2.0 are known to remove Shadow Volume Copies of the files, so this method may not work on all computers.

To restore a file, right-click over it, go into Properties, and select the Previous Versions tab. If the relevant file has a Restore Point, select it and click the "Restore" button.

Restoring files encrypted by CryptoDefense

If you cannot start your computer in Safe Mode with Networking (or with Command Prompt), boot your computer using a rescue disk. Some variants of ransomware disable Safe Mode making its removal complicated. For this step, you require access to another computer.

To regain control of the files encrypted by FilesLocker v2.0, you can also try using a program called Shadow Explorer. More information on how to use this program is available here.
