LanRan ransomware is a sneaky cryptovirus which seems to be a new version of the open-source MyLittleRansomware virus. On the affected machine, the virus changes the wallpaper and shows a lock screen. After infiltration, LanRan virus might modify Windows Registry. These alterations allow taking root into the system and activate malicious processes whenever the victim turns on the infected computer. However, the main purpose of the ransomware is to encrypt files immediately.[1] It uses RSA-2048 encryption algorithm and aims at the most popular file types, such as MS Office documents, multimedia files, etc. A ransom note, named @___help___@ and urging 0.5 BTC for a file decryption key, appears. Recently a new version of this ransomware has been released – LanRan v2 which uses the .LanRan2.0.5 file extension to corrupt data.

Thus, it takes over all personal files and important documents in order to convince more victims to pay the ransom. Although it’s easy to be threatened by the ransomware attack, the most important task is LanRan ransomware removal. Later you can think about the alternative ways to restore your files.

Once LanRan ransomware virus completes data encryption procedure, it drops a ransom note. The crooks ask to transfer 0.5 Bitcoins to the provided Bitcoin wallet address in order to purchase LanRan Decryptor. This tool is vital for data recovery, and people need to contact creators of the ransomware via email lanran-decrypter@list.ru if they want to get back access to their files.

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. Cybercriminals are not the ones who can be trusted.

Nevertheless, it’s not enough to remove LanRan from the computer to retrieve encoded data; this task is crucial. Only professional security tools, such as ReimageIntego can clean your computer from this cyber threat. If you encounter some obstacles, please scroll down to the third part of the article.

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.

  • Download Data Recovery Pro;
  • Follow the steps of Data Recovery Setup and install the program on your computer;
  • Launch it and scan your computer for files encrypted by LanRan ransomware;
  • Restore them.

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 ReimageIntego, SpyHunter 5Combo Cleaner or Malwarebytes

How to prevent from getting ransomware

Access your website securely from any location

When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. The best solution for creating a tighter network could be a dedicated/fixed IP address.

If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for the server or network manager that needs to monitor connections and activities. VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world.

 

Recover files after data-affecting malware attacks

While much of the data can be accidentally deleted due to various reasons, malware is one of the main culprits that can cause loss of pictures, documents, videos, and other important files. More serious malware infections lead to significant data loss when your documents, system files, and images get encrypted. In particular, ransomware is is a type of malware that focuses on such functions, so your files become useless without an ability to access them.

Even though there is little to no possibility to recover after file-locking threats, some applications have features for data recovery in the system. In some cases, Data Recovery Pro can also help to recover at least some portion of your data after data-locking virus infection or general cyber infection.
