Indeed, it might be hard to recover encrypted data if you do not have backups. The LanRan virus is likely to delete Shadow Volume Copies that are essential for the recovery. However, purchasing the decryption key from the hackers is not recommended either.[2] They might gladly take your money and leave you without the decryptor.

Bonus: Recover your data

Guide which is presented above is supposed to help you remove LanRan from your computer. To recover your encrypted files, we recommend using a detailed guide prepared by 2-spyware.com security experts.

Paying the ransom is not a safe and reliable way to rescue your files. Cybercriminals might not provide you decryption software or offer to use a malicious one. As a result, you will lose your money and might get infected with other malware. Thus, if you do not have backups, please try alternative recovery methods that might help to restore at least some of the files. However, LanRan deletion must be performed before.

If your files are encrypted by LanRan, you can use several methods to restore them:

Files encrypted by LanRan malware might be rescued with a help of Data Recovery Pro

Originally, this tool was designed to restore damaged or deleted files. However, developers update it in order to help victims from the ransomware to rescue at least some of encoded files.

Take advantage of Windows Previous Versions feature and restore files encrypted by LanRan virus

Windows Previous Versions feature allows accessing previously saved versions of the encrypted files, but only if System Restore function has been enabled before the attack. Otherwise, copying individual files is not valid.

  • Find an encrypted file you need to restore and right-click on it;
  • Select “Properties” and go to “Previous versions” tab;
  • Here, check each of available copies of the file in “Folder versions”. You should select the version you want to recover and click “Restore”.

LanRan decryptor

Nevertheless, cybercriminals offer to purchase decryption software; we do not recommend doing it. If none of the above methods have worked for you, or you still need to recover lots of files, please be patient and wait for the official LanRan decrypter created by the virus researchers.

Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from LanRan and other ransomwares, use a reputable anti-spyware, such as Reimage, Malwarebytes Malwarebytes or Plumbytes Anti-MalwareNorton Internet Security
