Ransomuserlocker Ransomware

Ransomuserlocker Ransomware is a dangerous threat that surfaced in January, 2018, i.e., just a few weeks ago. This new ransomware program seems to attack Korean computer users and is also referred to as the Korean Hidden Tear Ransomware. As you may already know, Hidden Tear was originally an open-source educational project for IT security experts; however, more and more malicious programs seem to stem from it, including Krypton Ransomware and Genocheats Ransomware. This new ransomware also targets your personal files to hit you hard but we do not believe that the ransom fee is reasonable for any private user to pay, not that we would ever encourage anyone to do so. In fact, it is always risky to transfer any money to such cyber criminals. We recommend that you remove Ransomuserlocker Ransomware from your computer immediately. Please read our full article to learn how you can protect your computer from similar dangers.

This vicious program may infiltrate your system in a couple of ways. If you understand these, you can possibly defend your PC from future attacks. First of all, the most likely way for these cyber villains to attack you is via spamming campaigns. This means that the malicious executable file will be sent to you in a spam mail as an attached file. This file can look like an image or a text document, which allegedly contains important information for you about a made-up issue. This spam may seem totally authentic to you and this is one of the reason why victims would open it in the first place. Another reason is the subject itself as it may relate to some urgent-looking matter like an unpaid invoice or fine, an undelivered parcel from FedEx, an issue with your credit card information regarding an online booking, and so on. Most likely, most people would want to see such a mail even if just out of pure curiosity, right? Well, the real problem with this is that the moment you open the attached file, you infect your computer with this malicious program. In other words, even if you manage to delete Ransomuserlocker Ransomware after this, your files will be encrypted.

It is also possible to drop such a dangerous infection if your browsers and drivers are not up-to-date and you "accidentally" land on a malicious website. This can easily happen if you click on corrupt content, such as a third-party banner or pop-up. However, before you could realize that you have been redirected to a malicious site and close the new tab or your browser window, Exploit Kits (e.g., RIG) can drop this infection in the background, so you will not even see it coming. This is why it is so important that you take updates seriously and remember to update all your programs on your computer regularly.

Our research shows that this new ransomware program could be work of the same cyber crooks who are responsible for Talk Ransomware, or Korean Talk virus. This malware infection also targets Korean speakers and uses the AES algorithm combined with the RSA algorithm to encrypt your photos, videos, documents, and more. The encrypted files get a ".RansomUserLocker" extension, so you can easily check how many of your precious files have been rendered inaccessible. After the damager has been done, this threat drops its ransom note, "Read_Me.txt," possibly on your desktop, and an application window opens with the note but it does not cover the full screen.

This note is in Korean. It informs you about the encryption and that the only way for you to get your files back is to send 1 BTC, around 8,000 USD, within 72 hours to a given Bitcoin address. There is also information about how or where to buy Bitcoin. Once the transfer is done, you are supposed to send your personal ID included in this ransom note to "" We do not advise you to pay at all but we do not think that a private user would have this kind of money to pay for the decryptor software and key. We recommend that you take action right now and remove Ransomuserlocker Ransomware from your PC.

We have prepared an easy-to-follow guide below so that you can manually eliminate this dangerous malware infection if you want to do so. It is not too complicate to accomplish this; however, we understand if you would prefer to use an automated security tool instead. Therefore, we suggest that you download and install a reliable anti-malware program, such as SpyHunter, which can also protect your computer automatically against all known threats in the future.
