LanRan Ransomware – Infection

LanRan ransomware could spread its infection via different methods. The payload file that initiates the malicious script for this ransomware, which in turn infects your computer machine, is circling the Internet. A few malware samples have been found by different malware researchers. You can see the VirusTotal detections for security vendors of one sample by checking the snapshot below:

LanRan ransomware could also distribute its payload file on social media sites and networks for file-sharing. Freeware that is found on the Web could be presented as useful but at the same time could hide the malicious script for the cryptovirus. Refrain from opening files just as you have downloaded them, especially if they come from suspicious sources such as links or e-mails. Instead, you should scan them beforehand with a security tool, while also checking the size and signatures of these files for anything that seems out of the ordinary. You should read the ransomware preventing tips thread in the forum.

LanRan Ransomware – More Information

LanRan ransomware is also a cryptovirus. Karsten Hahn and a few more malware researchers have discovered multiple samples of the malware. Moreover, they believe that the virus is a variant of “MyLittleRansomware”.

LanRan ransomware could make entries in the Windows Registry to achieve persistence, launch or repress processes in Windows. Some entries are designed in a way that will start the virus automatically with each launch of the Windows Operating System, such as the example provided down here:

→“HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run”

After the encryption process is finished, the ransom note will be displayed. The note is written in English. Inside, you will find instructions on what to do for file restoration. The note is contained in a file with the name @___help___@. You can preview the ransom note right down here:

The ransom note reads the following:

L_A_N_R_A_N R_A_N_S_O_M_W_A_R_E

What is encryption?
Encryption is a reversible modification of information for security
reasons but providing full access to it for authorized users. To become an authorized user and keep
the modification absolutely reversible (in other words to have a possibility to decrypt your files) you
should have an individual private key. But not only it. It is required also to have the special decryption software
in “LanRan Decryptor” software for safe and complete decryption of all your files and data.

good luck

The ransom note of the LanRan virus should not be followed. In the note is stated that the only way to revert your files back to normal is if you pay 0.5 Bitcoin, which is equivalent to 525 US dollars at the time of writing this article. That is not true and you should NOT under any circumstances pay these cybercriminals. Your files may not get recovered, and nobody could give you a guarantee for that. Furthermore, giving money to these crooks will likely motivate them to create more ransomware virus or do other criminal activities.

LanRan Ransomware – Encryption Process

A list with file extensions that the LanRan ransomware seeks to encrypt isn’t known at this moment. However, the article will get duly updated if such one is discovered. The extensions which are most likely to get encrypted are the following:

→.7z, .bmp, .doc, .docm, .docx, .html, .jpeg, .jpg, .mp3, .mp4, .pdf, .php, .ppt, .pptx, .rar, .rtf, .sql, .tiff, .txt, .xls, .xlsx, .zip

Every file that gets locked will be encrypted with the RSA 2048-bit algorithm.

The LanRan cryptovirus is more than likely to erase the Shadow Volume Copies from the Windows operating system by using the following command:

→vssadmin.exe delete shadows /all /Quiet
