What is RansomMine ransomware?

Authors of the RansomMine created malware for fun

Ransom note by RansomMine ransomware

RansomMine ransomware is a more a joke than a file-encrypting virus. The crypto-malware targets Korean computer users and encrypts files with AES cryptography. However, instead of demanding to pay the ransom, developers ask to play Minecraft for an hour in order to unlock files with .RansomMine file extension.

The malicious program spreads in RansomMine.exe file and might be delivered in the form of fake software update or download, malicious email attachment or using any other traditional ransomware distribution method.

Once inside, RansomMine virus might make several modifications to the system in order to run on system startup and start data encryption procedure. However, security experts claim that current variant of the virus is decryptable and there’s no need to follow hacker’s demands.

The RansomMine delivers a pop-up window, where it says in the Korean language that users can get back access to their files if they play Minecraft 1.11.2 for at least an hour. The translation of the ransom note:

Warning
Caution All external files are encrypted.
1. What is this?
Your videos, photos, documents, etc. have been encrypted. The program uses a powerful algorithm and cannot be recovered without this program.
2. How then do I?
It is very simple. You must have at least 1 hour play time for MineCraft. (Only version 1.11.2 should be used.) Then it will be decoded automatically.
And the key is fixed, but it does not mean that it can be recovered even if it is turned off like a hardware warship!

– the other phase –
MineCraft does not run

'The program is only for jokes, and it is not responsible for any problems you have encountered using this other program.

Differently, than other crypto-viruses, this one is not used for swindling the money. Nevertheless, it is used just for fun; you should still remove RansomMine. Well, if you’re a Minecraft player, you can try to follow crooks’ instructions. But once your files are recovered, don’t forget to uninstall a malicious program.

How to prevent from getting ransomware

Access your website securely from any location

When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. The best solution for creating a tighter network could be a dedicated/fixed IP address.

If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for the server or network manager that needs to monitor connections and activities. VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world.

 

Recover files after data-affecting malware attacks

While much of the data can be accidentally deleted due to various reasons, malware is one of the main culprits that can cause loss of pictures, documents, videos, and other important files. More serious malware infections lead to significant data loss when your documents, system files, and images get encrypted. In particular, ransomware is is a type of malware that focuses on such functions, so your files become useless without an ability to access them.

Even though there is little to no possibility to recover after file-locking threats, some applications have features for data recovery in the system. In some cases, Data Recovery Pro can also help to recover at least some portion of your data after data-locking virus infection or general cyber infection.
