ChinaYunLong ransomware virus. How to remove? (Uninstall guide)

removal by Alice Woods - - | Type: Ransomware

ChinaYunLong ransomware fails to deliver the ransom-demanding message correctly

ChinaYunLong ransomware

ChinaYunLong is a ransomware virus that was first spotted on June 18th, 2017. It is a file-encrypting computer virus[1] that works as an extortion tool. After infecting the computer, it encodes all documents, photos, and other files and adds .yl file extensions to their original filenames.

The ransomware then launches a program called China Yun Long with a picture of a human with the “Anonymous” mask and some scrambled lines below. The ransomware might also change the desktop wallpaper with a similar image.

The aim of this ransomware is clearly to extort money from people, however, due to an encoding error, the text of the ransom note is displayed incorrectly. Assuming that the ransomware was designed for Chinese-speaking users, foreigners won’t receive the message sent by the criminals.

At the moment of writing, there are no known methods that could allow decrypting files locked by China-YunLong virus. The ransomware is very new, and it needs to be analyzed before making any predictions. Until then, we suggest you remove ChinaYunLong ransomware and try out possible data recovery techniques. You can find a list of them down below.

It is also important to note that ransomware is no regular computer program and traditional software uninstallation methods may not work. Therefore, for a successful ChinaYunLong removal, we suggest using anti-malware tools like Reimage or Plumbytes Anti-MalwareMalwarebytes Malwarebytes.

Ransomware uses several attack vectors

The described ransomware mainly attacks unprotected computers as it spreads via mail spam, malvertising and possibly via RDP attacks[2]. In other words, it easily infects computers of inattentive computer users. To keep such viruses at bay, you need to remember that:

  • Ransomware viruses are usually transmitted in the form of documents or JS files that contain functions allowing them to address a particular domain and download the malicious executable from there. Therefore, you should never try to open files sent to you by strangers.
  • RDP attacks are extremely successful because computer users tend to use basic and easy-to-guess passwords on them. You should never rely on easy-to-remember passwords such as 123456789 or [your name]+123 because criminals can brute-force such passwords in a day.
  • Avoid browsing through illegal or suspicious websites. If you notice suspicious alerts urging you to install software updates or unknown programs, step out of such sites. These programs/updates can contain malicious files!
  • Create a data backup and install anti-malware software. These two are must-haves if you want to keep ransomware at bay and protect your files from unexpected encryption-based attacks.
