0000 ransomware removal instructions

What is 0000?

0000 is an updated version of a high-risk ransomware-type virus called CryptoMix. This malware was first discovered by MalwareHunterTeam. Once infiltrated, 0000 encrypts most stored files and renames them using the "[32_random_digits_and_letters].0000" filename pattern. For example, "sample.jpg" might be renamed to a filename such as "1F670AF7246B93059765E42328547745.0000". Henceforth, files become indeterminable and unusable. Once files are encrypted, 0000 places a text file ("_HELP_INSTRUCTION.TXT") in each existing folder.

The new text file contains a message informing victims of the encryption and encouraging them to contact cyber criminals (via one of the email addresses provided) to restore their compromised data. After sending the email, victims receive detailed decryption instructions. It is currently unknown which type of cryptography (symmetric or asymmetric) 0000 ransomware uses. In any case, decryption requires a unique key. Cyber criminals store these decryption keys on a remote server and victims are encouraged to pay a ransom to receive them. The size of ransom is also currently unconfirmed, however, developers of ransomware-type viruses typically demand $500-$1500 in Bitcoins, however, even if victims decide to pay, there is no guarantee that their files will ever be restored. Research shows that these people commonly ignore users, after the money is sent. There is a high probability that victims will be scammed. We strongly advise you to ignore all requests to contact these people or pay any ransoms. Unfortunately, there are currently no tools allowing users to decrypt compromised files free of charge. Therefore, the only solution is to restore everything from a backup.

0000 is very similar to dozens of other ransomware-type viruses such as ABC, Cyber Police, Teamo, and InfiniteTear. Although these viruses are developed by different cyber criminals, their behavior is identical. All encrypt stored data and make ransom demands. Research shows that the only major differences are size of ransom and type of encryption algorithm used. Most of these viruses employ RSA, AES, and other similar algorithms that generate unique decryption keys. Therefore, unless the malware has certain flaws (e.g., stores the key locally, it is hard-coded, etc.) or is still in development, restoring files manually, without developers help, is impossible. Ransomware-type malware is one of the main reasons why you should maintain regular data backups. Note, however, that backup files must be stored on a remote server (e.g., Cloud) or an external hard drive, otherwise the malware will also encrypt the backup files.

How did ransomware infect my computer?

Ransomware-type viruses are proliferated by employing trojans, fake software update tools, spam emails (infectious attachments), and unofficial software download sources (freeware download websites, free file hosting websites, peer-to-peer [P2P] networks, etc.) Trojans work simply - they merely open "gates" for malware to infiltrate the system. Meanwhile, fake software updaters infect the system by exploiting outdated software bugs/flaws. Malicious attachments typically (but not necessarily) come in the format of JavaScript files or MS Office documents. Once opened, these attachments download and install malware. Third party software download sources proliferate malware by presenting it as legitimate software. Users are tricked into downloading and installing malware.

How to protect yourself from ransomware infections?

The main reasons for computer infections are poor knowledge and careless behavior. The key to safety is caution. Be very careful when browsing the Internet. Keep installed applications updated and use a legitimate anti-virus/anti-spyware suite, however, as mentioned above, criminals proliferate malware via fake updaters. Therefore, we strongly advise you to update software using an implemented "Update" feature, or at least a tool provided by the official developer. Your software should also be downloaded from official sources only and, preferably, using a direct download link. Third party downloaders/installers often include malicious apps. Never open attachments received from suspicious email addresses - delete these emails without reading.

Step 2

Log in to the account infected with the 0000 virus. Start your Internet browser and download a legitimate anti-spyware program. Update the anti-spyware software and start a full system scan. Remove all entries detected.

If you cannot start your computer in Safe Mode with Networking, try performing a System Restore.

1. During your computer start process, press the F8 key on your keyboard multiple times until the Windows Advanced Options menu appears, and then select Safe Mode with Command Prompt from the list and press ENTER.

Boot your computer in Safe Mode with Command Prompt

2. When Command Prompt mode loads, enter the following line: cd restore and press ENTER.

4. In the opened window, click "Next".

restore system files and settings

5. Select one of the available Restore Points and click "Next" (this will restore your computer system to an earlier time and date, prior to the 0000 ransomware virus infiltrating your PC).

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 0000 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 0000 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 0000, you can also try using a program called Shadow Explorer. More information on how to use this program is available here.

To protect your computer from file encryption ransomware such as this, use reputable antivirus and anti-spyware programs. As an extra protection method, you can use programs called HitmanPro.Alert and EasySync CryptoMonitor, which artificially implant group policy objects into the registry to block rogue programs such as 0000 ransomware.

Note that the Windows 10 Fall Creators Update includes a "Controlled Folder Access" feature that blocks ransomware attempts to encrypt your files. By default, this feature automatically protects files stored in the Documents, Pictures, Videos, Music, Favorites as well as Desktop folders.

Controll Folder Access

Windows 10 users should install this update to protect their data from ransomware attacks. Here is more information on how to get this update and add an additional protection layer from ransomware infections.

HitmanPro.Alert CryptoGuard - detects encryption of files and neutralises any attempts without need for user-intervention:
