Lokd virus is a new malware that encrypts all files on an infected computer using a strong hybrid encryption system and a unique key. Each encrypted file gets a new .lokd file extension. Even if you delete the new extension or completely rename the file, it will not help restore access to its contents. Only the key and decryptor, which are in the hands of the authors of the Lokd virus, can decrypt the files. Fortunately for the virus victims, a free decryptor is created, which in some cases can help decrypt .lokd files.

What is Lokd ransomware virus?
Lokd is a malicious program that belongs to the group of STOP (Djvu) ransomware viruses. This virus can infect almost all modern versions of the operating systems of the Windows family, including Windows XP, Windows Vista, Windows 7, Windows 8, Windows 10. It uses a hybrid encryption mode and a long RSA key, which virtually eliminates the possibility of hacking the key. Lokd ransomware virus is usually spread through hacked programs, key generators, activators and adware. When a user launches such a program, the computer becomes infected with this ransomware virus.
Lokd uses system directories to store its own files. In order to run automatically each time the OS starts, the ransomware creates an entry in the Windows registry section that defines the list of programs that start when the computer is turned on or rebooted.
To determine which key to use for encryption, Lokd virus tries to establish a network connection with its command server. The virus transmits information about the infected computer to the server, and receives the encryption key from it. In addition, the command server can transmit additional commands and modules to the virus that will be executed on the victim’s computer.
If the data exchange with the command server was successful, then the virus uses the received encryption key (online key). This key is unique for each infected computer. If Lokd could not establish a connection with its server, then a fixed key (offline key) will be used to encrypt the files. This key is the same for all infected computers. This key can be determined by security researchers, which gives hope to the victims of Lokd virus, in some cases, to decrypt the files affected by it.
Lokd virus can encrypt all files on the victim’s computer, no matter where they are. Files located on the internal drives of the computer, connected external devices and cloud storage can be encrypted. The type of file and its contents are not important for the virus; any file can be encrypted. The only thing is that the virus does not encrypt files located in the Windows system directories, as well as files with the name ‘_readme.txt’.
After the file is encrypted, it will be renamed. The virus adds the .lokd extension at the end of its name. In every directory where at least one file has been encrypted, the virus creates a file called “_readme.txt”. Example contents of this file:

Lokd authors report that the victim’s files are encrypted and the only way to decrypt them is to buy a key and a decryptor, that is, to pay a ransom. Attackers demand $980, if the victim agrees to pay the ransom within 72 hours, then the ransom is reduced to $490. Criminals offer to decrypt one file for free and thus confirm that it is possible that the victim can return all his files. Of course, successful decryption of one file does not guarantee that after the ransom is paid in full, the victim will receive a key and a decryptor.

Is my computer infected with Lokd virus?
Determining whether a computer is infected or not is quite easy. Try opening your files, such as documents, photos, music, etc. in relevant programs. If, for example, when you open a document, Windows reports that the file is of an unknown type, then most likely the document is encrypted and the computer is infected. Of course, the presence of files with the extension .lokd and files with the name _readme.txt is also a 100% sign of ransomware infection.

How to recover files encrypted with Lokd virus
Unfortunately, free Lokd decryptor is not always able to decrypt files. But even in this case, it is possible to restore the contents of encrypted files. Below in this article we will give several ways, please try all of them. Perhaps one of them will allow you to completely restore the files, or rather, return them to their original state, to the state that was before their encryption.
At this stage, I want to emphasize that before recovering files, you must definitely check your computer for viruses, find and remove malware that encrypted your files. The only way to skip this step is to get the disk with encrypted files and connect it to another computer, then use it to restore your files. Attention, using a disk on another computer, there is a small chance that you accidentally infect that computer with this virus.
Restore .lokd files using ShadowExplorer
To restore documents, photos, databases and other important files, that is, practically “decrypt .lokd files without a key,” we first recommend using a free program called ShadowExplorer. If you have not come across this program, then here is some information about it. It is a small utility that allows you to easily access copies of files that are created automatically by a standard Windows function called ‘Windows Previous Versions’.
Download the program using the link that you can find below. We recommend that you save the downloaded file to your desktop, so you can easily find it after the download is complete.
When the program download is complete, you will see a file called ShadowExplorer-0.9-portable.zip. The utility is in the archive, so you need to unzip the archive before starting the program. Right-click on this file and select the option called Extract All. Now open folder ShadowExplorerPortable.
In the list of files, find the ShadowExplorerPortable program and run it.
The main program window will open before you, as in the following example. The main window is divided into two parts – left and right. In the left part of the window, select the drive on which the encrypted files are located and select the date closest to the moment when the virus attacks your computer, encrypts the files and has changed the file extension to .lokd. In the right part of the window, select the file you want to restore, then right-click on it.
A small pop-up menu will open before you, select Export in it. In the next window, select the directory where the recovered files will be saved.
What else do I want to say about the process of recovering encrypted files using the ShadowExplorer tool. Unfortunately, very often ransomware disable the Windows Previous Versions function and delete all saved copies of files. Therefore, after starting the ShadowExplorer, you may find that it is impossible to recover files. In this case, use another method of recovering encrypted .lokd files, which is given below.
Restore .lokd files using PhotoRec
Another way to recover encrypted .lokd files is the ability to use utilities designed to find and recover accidentally deleted and lost data. We recommend that you use the free PhotoRec tool. It is one of the best and has already helped readers of our site repeatedly recover encrypted files in a seemingly absolutely hopeless situation.
Before using the program, you need to download it. Use the link below.
When the file is downloaded, in the folder where you saved it you will see a file with the name ‘testdisk-7.0.win_.zip’. This file is the archive that contains the PhotoRec. To use the PhotoRec, this archive must be unzipped. Right-click on the file and select the item called Extract All. Open the folder with the name testdisk-7.0, you will see a list of files similar to the one below.
In the contents of the directory that opens, find the file with the name QPhotoRec_Win and run it. You will be shown a window similar to the one in the following figure. This is the main PhotoRec window.
Here you need to select the physical disk and the disk partition (disk name) where the encrypted .lokd files are located. Note that in section ‘File System Type’, option ‘FAT/NTFS’ must be selected. Now select the folder where the recovered files will be written. We recommend using a partition or drive that does not contain encrypted files. It is better to use external media. It is very important! Since the PhotoRec restores files that were deleted by the Windows OS, if you restore them to the same drive on which you are trying to find them, a situation may occur when the Windows simply physically overwrites them and you can no longer recover such files.
Next, at the bottom of the window, click File Formats. A small window opens that lists the types of files that the PhotoRec can find and restore.
Leave only those file types that you need to recover selected. For example, if you want to restore images of ‘jpg’ format, then select the file type ‘jpg’. Having decided which files to recover, click OK button.
Having completed the steps listed above, you have made all the settings necessary to search and restore encrypted .lokd files. It remains only to click on the Search button. The process of searching and restoring files can take a very long time, be sure not to turn off the computer or restart it. During this process, the program will show the current search location (disk sector), how many and which files were found and restored.
When the file recovery process is complete, click the Quit button. Then open the directory that you previously selected as the place where the recovered files will be written.
Here you will see one or more directories with the name recup_dir (recup_dir.1, recup_dir.2, …). Check these folder to find the files you need. The file name may not be restored, so to find what you need, use file sorting, as well as the standard Windows OS search by file contents.
