How to remove LANDSLIDE Ransomware

LANDSLIDE ransomware is a notorious kind of computer virus. It serves as instrument for attackers to engage their victims into paying for the program that will liberate their important files. In order to arrive in this situation, makers of LANDSLIDE will attack the computer and render the files inaccessible by encrypting them with a complex AES+RSA method. Then, this virus will insert a multipart strings on the file extension, which serves as naming pattern to identify the encrypted files. For example, the ordinary data abc.doc will become [nataliaburduniuc96@gmail.com] [id = A4F72DE12] abc.doc.LANDSLIDE after it was fully encrypted by the ransomware.

How LANDSLIDE Virus Spreads?

Every bits and pieces of ransomware are capable of spreading globally. It really depends on how the attackers will purposely deploy it online. It may target users and organization worldwide or just the specific geographical area. Same thing goes with LANDSLIDE ransomware. This threat can reach the computer in various methods but the more efficient phishing email is in effect and the virus could reach thousands of inboxes in one send off.

By using the spam mass-mailing campaign, the virus is embedded to email and purporting as legitimate document. It holds an enticing message that can spellbind the recipients to open the attachment file, which usually titled business inquiry, shipping method, parcel delivery, payment, tax, and similar. Once the attached file is opened, LANDSLIDE instantly initiates the infection vector that usually starts with the dropping of the virus copy on System folder of Windows.

Freeware, shareware, cracked applications, serial key generators, or bogus software updates are some executable files that easily launch LANDSLIDE ransomware infection on the computer. Usually, users are actively downloading these types of programs from malicious sites and pop-up ads. Once executed, it launches the infection and soon, it starts to perform hazardous actions on the computer.

LANDSLIDE Ransomware File Encryption

After activating the virus through spam emails, malicious programs, or brute force methods, it attempts to communicate with a remote server to download extra malware. LANDSLIDE ransomware will likewise obtain commands and public key from the said server. Then, it will apply a complex algorithm method and uses the obtained public key to render majority of computer files inaccessible. With the mentioned complex encryption system, file recovery appears to be impossible without the decryption software and a private key, which the attacker possesses. Because of the unavailability of free or third-party LANDSLIDE decryption software, some victims are left without any choice but to pay the ransom money demanded by attackers. Below are the excerpt and image of the ransom note that LANDSLIDE virus generated on the infected computer.

Backup your files

One important step before proceeding with the procedures below is to backup your files. Ransomware are not the same. Each has its unique sets of payloads aside from encrypting the files with complex method. Others tend to delete the infected files after certain period, while others keep them concealed on hidden places. In addition, ransomware decryption tools are not guaranteed to be perfect, there are instances that files suffer from damages during the decryption process.

So, create a backup copy of your entire LANDSLIDE encrypted files right now.

Recover Files from LANDSLIDE Ransomware Infection

On this section, we will provide ways to decrypt files infected with LANDSLIDE ransomware. Aside from dedicated decryption software and common tools, other options for file recovery are provided. As much as we can, we will update this area whenever there is new and more suitable decryption tool was made available.

Decrypting LANDSLIDE infected files with Emsisoft Tools

This service from Emsisoft is helpful in unlocking encrypted files without paying the ransom. It gives three ways to detect the ransomware and provide suitable recovery method:

Upload ransom note – This is usually the .txt or .hta files that was generated by LANDSLIDE ransomware.

Upload the encrypted file – The actual encrypted file. Choose the one that is less than 8MB in size.

Contact information – Enter the email address or any links provided as it appears in the ransom note of LANDSLIDE virus.

Emsisoft Tools

After submitting any of the appropriate data, Emsisoft will attempt to identify the ransomware and provide keys if there are available.

Option 1: Windows Previous Version Tool

Windows Vista and Windows 7 have a feature called Previous Versions. However, this tool is only usable if restore point was made prior to ransomware infection. To use this tool as "recovery option" for files encypted by LANDSLIDE virus, please follow these steps:

1. Open My Computer or Windows Explorer.

2. Right-click on the affected files or folders. From the drop-down list, please click on Restore previous versions.

3. New window will open display all backup copy of files and folders you wanted to recover. Choose the appropriate file and click on Open, Copy, or Restore. Restoring selected files overwrites the current locked files on the computer. The tool is not actually recovering files encrypted by LANDSLIDE. Instead, it restores files from backup copy.

Option 2: Use ShadowExplorer to restore files encrypted by LANDSLIDE Ransomware

Just like Previous Version tool, ShadowExplorer is taking advantage of shadow copy created by Windows. This tool allows you to retrieve older version of files before it was encrypted by LANDSLIDE ransomware.

1. Download ShadowExplorer from the official web site.

2. Install the program with the default settings.

3. The program should run automatically after installation. If not, double-click on ShadowExplorer icon.

4. You can see the drop-down list on top of the console. Please select proper drive and the most recent point-in-time shadow copies of files you wish to restore prior to LANDSLIDE ransomware infection.

5. Right-click on the Drive, Folder, or File you wish to restore and click Export...

6. Lastly, ShadowExplorer will prompt for location where you want to save the copy of recovered files.

How to protect the computer from LANDSLIDE ransomware?

After the removal of the ransomware, it is important to prevent similar incident from happening again. In order to protect the computer effectively, computer user must know how LANDSLIDE ransomware was able to infect the computer. To minimize the possible infection, staying away from the common sources of this virus is crucial.

How LANDSLIDE ransomware can infect your computer?

The method of infecting the computers was found to be similar as other common viruses. Though, ransomware like LANDSLIDE is seen to have efficient deployment via spam email messages, web injectors, malicious software installers, misleading online advertisements, and through another virus infection.

Once the virus is executed, it immediately infects the system. Then, LANDSLIDE ransomware communicates to remote server so that unique key can be generated for the specific computer. After acquiring the key, it starts to decrypt target files using a complex method that is almost unbreakable. On the last stage of the attack, LANDSLIDE ransomware demands for ransom money as payment for the decryption tool. To further understand the attack scheme, we have included an infographic below.
