Remove NanoLocker Ransomware and Restore Encrypted Files

nanolocker-main-sensorstechforumA new ransomware has recently appeared, going by the name of NanoLocker Ransomware. The malicious infection may encrypt the important user files on the hard drive as well as portable drives attached to the victim computer with a new extension. Such files become corrupt, and the only way to decrypt them is via a decryption key. The ransomware may also leave a ransom note with ransom instructions, demanding money from the victims. All users affected by NanoLocker Ransomware are strongly advised not to pay any ransom money that may be requested from them and to look for alternative methods for decryption and removal, instructions for which we have provided after this article.

NanoLocker Ransomware – How Did I Get Infected with It

This ransomware may be distributed in more than just malicious web links posted in spam comments online. Such links or attachment files may be included in spam e-mails as well. One of such mails may contain the following types of malicious attachments or archives:

Files: .docx; .bat; .vbs; .exe; .pdf;
Archives: .zip; .rar

Furthermore, the ransomware may be distributed via malicious files shared in torrent websites that are not reputable. Such files may be a malicious payload carrier, resembling a keygen, crackfix or a patch for a video game or other software.

NanoLocker Ransomware – What Does It Do

According to Symantec Security Response, once its malicious files have affected the user PC, the ransomware may displays a fake PDF error message and begins to drop its module files:

  • %UserProfile%\Desktop\ATTENTION.RTF
  • %UserProfile%\Desktop\Decryptor.lnk
  • %UserProfile%\Application Data\lansrv.exe
  • %UserProfile%\Application Data\lansrv.ini

These files are also known as modules or payload of the ransomware. The Ransomware infection then creates this registry entry for one of the modules:

→HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run\”LanmanServer” = “%UserProfile%\Application Data\lansrv.exe”

After these processes are done, the NanoLocker ransomware may run a module which begins to scan your computer for files of the most commonly used extensions and encrypt them:

After the encryption is successful, the user may see his files to become corrupt when he/she tries to open them. They may also have unfamiliar file extension and the user`s wallpaper may be changed, along with files dropped on his desktop that may contain the following message with instructions on how to bring back his/her files:

Furthermore, the ransomware may also have the ability to delete Volume Shadow Copies and backups so that there is no way of decrypting the data. What is more is that the NanoLocker ransomware may open ports to connect to remote hosts, one of which is 52.91.55.122. This is believed to be the Command and Control (C&C) center ran by the cyber-criminals.
