Ranrans ransomware removal instructions

What is Ranrans?

Ranrans is a ransomware-type virus that stealthily infiltrates systems and encrypts stored data. In doing so, this malware appends names of encrypted files with the ".ranrans" extension (for example, "sample.jpg" is renamed to "sample.jpg.ranrans"). Following successful encryption, Ranrans locks the computer screen and displays a ransom-demand message.

The message states that files are encrypted and that victims must pay a ransom of the equivalent of $50 in Bitcoins to restore them. It is currently unknown whether Ranrans uses symmetric or asymmetric cryptography, however, in any case, decryption without a unique key is impossible. Cyber criminals store this key on a remote server and victims are encouraged to pay a ransom to receive it. Although the cost is small as compared to other ransomware (ransom demands usually fluctuate between $500 and $1500), you should never trust or pay these people. Research shows that cyber criminals often ignore victims once payments are submitted. There is a high probability that paying will not deliver any positive result and you will probably be scammed. In addition, you will support cyber criminals' malicious businesses. Unfortunately, there are no tools capable of restoring files encrypted by Ranrans and you can only restore your files/system from a backup.

Ranrans shares many similarities with dozens of other ransomware-type viruses such as, for example, Oxar, Bit paymer, PowerShell, and Nemesis. As with Ranrans, these viruses also encrypt files and make ransom demands. In fact, there are just two major differences: 1) size of ransom, and; 2) type of encryption algorithm used. Ransomware viruses often employ cryptographies that generate unique decryption keys (for example, RSA, AES). Therefore, restoring files manually is mostly impossible.

How did ransomware infect my computer?

To proliferate ransomware, cyber criminals often employ spam emails (infectious attachments), peer-to-peer (P2P) networks (for example, torrents, eMule, etc.), unofficial software download sources (freeware download websites, free file hosting websites, etc.), fake software update tools, and trojans. Malicious attachments are usually delivered in the format of JavaScript files or MS Office documents (with macros) that download/install the malware. P2P networks and other unofficial software download sources often proliferate malware by presenting it as legitimate programs. Fake software update tools exploit bugs of old software versions to infect the system.

How to protect yourself from ransomware infections?

To prevent this situation, be very cautious when browsing the Internet. Firstly, never open files received from suspicious emails. Secondly, download your software from official sources and keep installed applications up-to-date. Be aware, however, that criminals proliferate malware via fake updaters. Therefore, never trust third party software update tools and use a legitimate anti-virus/anti-spyware suite. The key to computer safety is caution.

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 Ranrans 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 Ranrans 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 Ranrans, 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 Ranrans ransomware.

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