Ransom note by RansomUserLocker ransomware

RansomUserLocker is a file-encrypting virus that is a version of Korean HiddenTear ransomware. It uses .RansomUserLocker file extension to make data on the targeted computer inaccessible. Once it finishes encryption procedure, it drops a Read_Me.txt file and delivers a lock screen message with data recovery possibilities.

The RansomUserLocker virus emerged in January 2018, as well as a couple of other ransomware infections that aims at Korean computer users. According to the primary research data, malware is created by the same authors as recently discovered Talk ransomware (also knowns as Korean Talk virus). Additionally, it resembles VenusLocker ransomware which was active in Korea in 2017. 

The RansomUserLocker ransomware uses a combination of AES And RSA cryptography to damage files on the computer.

After making a transaction (not recommended), victims are asked to send their ID number provided in the ransom note to

However, instead of paying the ransom users are advised to remove RansomUserLocker from their computers. There are no guarantees that crooks will send you a decryption software and a needed key. Ransomware is illegal money-making business. Thus, once hackers receive their money, their job is done.

Hence, to avoid a huge amount of money loss, you should obtain a reputable malware removal tool, such as Reimage, and run a full system scan with it. Automatic RansomUserLocker removal ensures that all malware-related entries are wiped out from the system safely.

Ransomware-type cyber threats are capable of injecting malicious codes into legit system processes, installing numerous files and components, as well hiding them deep in the system. For this reason, it’s not recommended trying to delete RansomUserLocker manually.

The way ransomware spreads and how to avoid it

Malware payload RansomUserLocker.exe is being spread via malicious spam emails, bogus downloads, fake updates, cracked software, malicious ads and other tricky methods. However, users can protect themselves from the cyber attack.

Unfortunately, it’s not enough to install an antivirus program and feel 100% protected. Some cyber threats are capable of bypassing cyber security. Thus, you have to be careful with your actions online:

  • Do not open spam emails and unknown attachments. It’s the main ransomware distribution method.[1] Thus, if you did not expect to receive an invoice, statement or other “important” document, do not open attachment. The security team from[2] also report that buttons and links in the emails might be malicious too.
  • Do not click on eye-catchy or aggressive ads[3] because they might include malicious content or redirect to infected sites.
  • Do not install software updates from pop-ups or third-party download sites. Legit updates are installed automatically, or they are available on the official download sites.
  • Avoid using third-party software download sources, such as torrents or P2P networks.

Additionally, you should keep your programs and operating system up-to-date. Outdated software or unpatched system might have vulnerabilities and flaws. Thus malware can take advantage of them an attack the device.
