What is CoinVault!

CoinVault is an annoying ransomware infection that will deny you the access to any of your files once it has managed to reach your system. The program will encrypt your files and will ask you to pay a certain amount of money in order to decrypt them. Moreover, it will threaten you that if you do not pay the money and try to delete this software, you will not be able see your original files ever again. The most important thing in this situation is not to panic because CoinVault is not as serious an infection as it pretends to be.

How did I get infected with CoinVault ransomware?

We do not think that there is anyone who expects programs of the type of CoinVault to manifest themselves when entering users’ computers. The infiltration is done silently and users only realize the infection is present when they notice that their files are blocked and when they see the notifications. CoinVault usually arrives on the system when users click on random ads they see on malicious or infected websites, also when they install fake program updates and false video codecs, open spam email attachments, etc. The bottom line is that you should avoid browsing through unknown web pages and downloading software from suspicious sources if you do not want such infections on your PC.

Why is CoinVault dangerous?

The creators of CoinVault, who are obviously cyber criminals, use certain scare tactics to convince you to pay the money requested. For example, you will be given 24 hours to purchase an encryption key and if you do not manage to do that within the time given, the amount you have to pay will be doubled. This is done to put more pressure on you so that you fall for the trick more easily. Under no circumstance should you pay anything as your bank account details may be stolen by the program’s developers. Once you manage to decrypt your files, you should also delete CoinVault because it might encrypt them again in future.

In the picture above you see two hidden files. You are interested in every file that looks like ~WRL382.tmp This is actually a Microsoft office junk file that contains the previous version of the Word document itself. The CoinVault parasite will not encrypt these files. The name of the file will be unknown, but you can recover a lot of lost documents using this method. This can be utilized for Microsoft Word and Microsoft Excel. In addition you can try to match the file sizes in order to figure out what is what and eventually you can restore a slightly older original document.
