What Is L47 Virus

L47 Virus FilesIf your files

L47 virus is the name of a ransomware infection, whose main idea is to encrypt your files and hold them like a hostage until you pay the criminals who are behind the virus a huge sum of money in BitCoin or another untraceable cryptocurrency. The main problem with viruses, like L47 is they encode the files, changing their structure. After encryption, this virus adds the .L47 file extension to the files that are encoded. Then, it leaves a ransom note file, called HOW_TO_RECOVER_DATA.html, containing the instructions provided by the criminals on how to pay the ransom itself.

L47 Virus – What We Know About It

Just like the .LR variant of MedusaLocker, L47 is the kind of ransomware that may infect your computer system in more than one way. The two main methods of infections used by this threat are likely the following:

  • If downloaded as a file from a third-party website.
  • If it is an e-mail attachment.

In case your computer has been infected by this version of MedusaLocker via e-mail, then there is a high chance the virus could have pretended to be some sort of a document that appears very important, such as:

  • E-receipts.
  • Invoices.
  • Work-related files.
  • Tickets.

There is also the scenario that you may have gotten yourself infected by downloading the wrong file. And by the wrong file we mean that you may have been looking for some software on third-party sites for free downloads, like:

  • Keygen (key generator activators).
  • Hoax setup.
  • Portable app.
  • Crack (activators).
  • Patch.

Once the L47 ransomware infects your computer, it may drop its virus files in the following directories of your system:

  • %Temp%
  • %LocalLow%
  • %Local%
  • %AppData%
  • %SystemDrive%

L47 ransomware is the kind of program that may also tamper with the following Windows registry sub-keys:

  • Run.
  • RunOnce.

The virus may use those to add value strings in them that make its infection files run automatically when you start your OS.

Among the dropped files by this virus on your computer is its ransom note. It is currently called HOW_TO_RECOVER_DATA.html and carries the following extortionist message:

medusalocker

.L47 Files

This variant of Medusa may scan for and encrypt your most often used files that may be of the following file types:

  • Archives (.zip, .rar, etc).
  • Image files (.jpg, .png, .etc).
  • Document file types (.docx, .pptx, etc.).
  • Audio (.mp3, .wav, etc.).
  • Video files (.mp4, .avi, etc.).
  • Other.

When the L47 virus encrypts your files, it may leave them with a changed data structure. This means that even if you remove the .L47 you may not fix the files and may damage them even further.
