Rabbit4444 ransomware removal instructions

What is Rabbit4444?

Discovered by Raby, Rabbit4444 is an updated variant of high-risk ransomware called Maoloa. The purpose of this ransomware is to encrypt data so that developers can make ransom demands by offering paid recovery of files. During encryption, this infection renames each file by appending the ".Rabbit4444" extension (e.g., "1.jpg" is renamed to "1.jpg.Rabbit4444"). Additionally, Rabbit4444 generates a text file called "HOW TO BACK YOUR FILES.txt" and stores it on the desktop.

As with most ransomware infections, Rabbit4444 uses a text file to deliver a ransom-demand message stating that files are encrypted and that victims must purchase a decryption tool to restore them. Be aware that Rabbit4444 encrypts data using an algorithm that generates an individual decryption key for each victim. Cyber criminals intentionally hide all keys on a remote server so that they can make ransom demands - to restore data, each victim must purchase a decryption tool with the key embedded within. The cost is not specified. This information is provided via email, however, cyber criminals typically demand $500-$1500 in Bitcoins, DASH, Monero, Ethereum, or other cryptocurrencies. Victims are also offered free decryption of some files as 'proof' that data can be restored and these people can be trusted. In fact, you should never trust these people. Many ransomware developers ignore victims once payments are submitted. No matter what the cost, do not pay, since this is unlikely to deliver any positive result. Unfortunately, Rabbit4444 is undecryptable ransomware and there are no tools capable of cracking the encryption and restoring data free of charge. The only possible scenario is to restore everything from a backup, if one has been created.

Rabbit4444 shares many similarities with Darus, JSWRM, foSTE, and hundreds of other ransomware infections. Note that, although the developers are different, all of these infections have identical behavior - they encrypt data and make ransom demands. The only major differences are size of ransom and type of encryption algorithm used. Unfortunately, most of these viruses employ cryptographies such as RSA, AES, and others, that generate unique decryption keys. Therefore, if data is encrypted by ransomware (that does not have bugs or flaws), only cyber criminals are capable of restoring it. We strongly recommend that you maintain regular backups and store them on remote servers or unplugged storage devices, since ransomware encrypts backups together with regular data. You are also advised to have several copies of backups and store them in different locations, since there is always the chance that servers/storage devices can be damaged.

How did ransomware infect my computer?

In most cases, infections such as Rabbit4444 are distributed using third party software download sources (Peer-to-Peer [P2P] networks, freeware download websites, free file hosting sites, etc.), spam email campaigns, trojans, and fake software updaters and 'cracks'. Unofficial software download sources present malware as legitimate software. In doing so, criminals often trick users into manual download/installation of malware. Spam email campaigns are also used in a similar manner. Criminals send hundreds of thousands of emails that contain deceptive messages encouraging recipients to open attached malicious links/files. Trojans stealthily infiltrate computers and inject them with additional malware. Fake updaters exploit outdated software bugs/flaws or merely download and install malware rather than updates. The same applies to fake cracks, which inject malware rather than activating paid applications free of charge. Note that careless behavior and lack of knowledge of these threats are the main reasons for computer infections.

How to protect yourself from ransomware infections?

To prevent ransomware infections, be extremely careful during the download/installation/update processes and when browsing the Internet. Your programs should be downloaded from official sources only and, if possible, using direct download links. The same rules apply to software updates - installed applications/operating systems should be updated using implemented functions or tools provided by the official developer. Third party downloaders/installers/updaters often include rogue apps, and thus these tools should not be used. Never attempt to crack installed applications, since software piracy is a cyber crime and the risk of infection is extremely high (most cracking tools are fake). Handle all email attachments with care. Files/links that are irrelevant or do not concern you should not be opened. Attachments received from suspicious/unrecognizable email addresses should also be ignored. Have a reputable anti-virus/anti-spyware suite installed and running, since this will significantly reduce the chance of infection - the software detects and eliminates malware before it can harm the system. If your computer is already infected with Rabbit4444, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

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 Rabbit4444 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 Rabbit4444 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 Rabbit4444 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 Rabbit4444, 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 Rabbit4444 ransomware.

Note that 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.
