UmbreCrypt virus (Easy Removal Guide)

UmbreCrypt virus Removal Guide

What is UmbreCrypt virus?

What should you know about UmbreCrypt virus?

First of all, do not panic if your computer got infected with UmbreCrypt virus. Even though it is an extremely dangerous malware, there is still a chance you can get your files back. This virus works similarly to other ransomware programs which require a fee in exchange for the decryption of your files, such as Locky virus, Cryptowall, CTB Locker and many others. Yet, unlike dealing with these other programs, when infected with UmbreCrypt ransomware it is possible to decrypt the locked files without paying a ransom. Also, make sure you delete this fraudulent program itself from your computer as well, to get rid of the initial threat.

You have to be aware that as soon as UmbreCrypt enters your computer, it starts carrying out its malicious activities and can cause a lot of trouble. All the means through which this program attacks your system are designed to generate quick and easy profit for the developers of this virus. Once in the system, UmbreCrypt virus scans it for different video, audio, text files, archives and other. The list of file extensions this virus can affect includes .dim, .diy, .dna, .dov, .dpb, .dsb, .fbc, .fbf, .fbk, .fbu, .fbw, .fh , .fhf, .flka, .flkb, .fpsx, .ftmb, .ful, .fwbackup, .fza, .fzb, .gb1, .gb2, .gbp, .ghs, .ibk, .icbu, .icf, .inprogress, .ipd, .iv2i, .jbk, .jdc, .kb2, .lcb, .llx, .mbf, .mbk, .mbw, .mdinfo and other files. These documents are then encrypted with an AES algorithm, which is a symmetric method of encryption meaning that the files can be decrypted with the same key used for encryption. Ransomware programs, however, encrypt the decryption key itself, using the RSA cryptosystem, so it is virtually impossible for the victims to decrypt the files themselves. After the files are encrypted, the victim receives a note asking to contact the developers of this ransomware. Only after the perpetrators are notified, the amount of money needed to redeem the files will be disclosed. The victim is also given a deadline of 3 days to notify the virus developers.

No matter how desperate the situation is, we do not recommend paying the ransom. Since this virus does not provide secure server connections, they might also be unable to send you the decryption key. Therefore, we advise you to attempt decrypting the files with the expert-prepared decryption key, but before you do that, make sure you entirely remove UmbreCrypt virus from your system. You can do that by using some reputable anti-malware program like ReimageIntego.

How did my computer get infected with this virus?

Since the UmbreCrypt removal and file retrieval procedure is long and difficult, it is better to protect yourself from being infected beforehand. There are some things you must know to avoid putting yourself at a risk of contracting this virus. First of all, this ransomware is an affiliate program of the HydraCrypt ransomware group. Therefore, it spreads similarly to the viruses of this particular family, via exploit kits. This means that if you want to be safe from malicious programs like these, you should avoid visiting unknown websites or pages, which may be filled with some infectious content. You should also be aware that it is relatively easy to get infected with this virus. You simply have to click on a flash advertisement, and it will redirect you to some third-party websites where your system will be infiltrated. Computer security experts claim that it is possible for this virus to spread through remote desktop connection. In other words, Umbrecrypt ransomware can spread directly. As long as these claims are not entirely confirmed, full attention should be focused on taking precautions against this infection.

How to prevent from getting ransomware

Stream videos without limitations, no matter where you are

There are multiple parties that could find out almost anything about you by checking your online activity. While this is highly unlikely, advertisers and tech companies are constantly tracking you online. The first step to privacy should be a secure browser that focuses on tracker reduction to a minimum.

Even if you employ a secure browser, you will not be able to access websites that are restricted due to local government laws or other reasons. In other words, you may not be able to stream Disney+ or US-based Netflix in some countries. To bypass these restrictions, you can employ a powerful Private Internet Access VPN, which provides dedicated servers for torrenting and streaming, not slowing you down in the process.

Data backups are important – recover your lost files

Ransomware is one of the biggest threats to personal data. Once it is executed on a machine, it launches a sophisticated encryption algorithm that locks all your files, although it does not destroy them. The most common misconception is that anti-malware software can return files to their previous states. This is not true, however, and data remains locked after the malicious payload is deleted.

While regular data backups are the only secure method to recover your files after a ransomware attack, tools such as Data Recovery Pro can also be effective and restore at least some of your lost data.
