LanRan v2 Ransomware – Overview

LanRan ransomware was first spotted to harass online users in March 2017. A day ago security researchers detected new sample of the threat that is currently spreading in active attack campaigns. This iteration of LanRan ransomware is considered to be version two as suggested by the specific extension .LanRan2.0.5 associated with the threat.

Ransomware is a threat with a complex code that is not only set to corrupt valuable data but your whole system. Various obfuscation techniques may conceal the ransomware presence on the system and keep it invisible until it fulfils all malicious activities set in its code.

Some of the modifications implemented by LanRan v2 ransomware are likely to affect the certain registry keys stored in the Registry Editor. Among the most targeted ones are Run and RunOnce as they control the automatic execution of all essential processes each time the system is started as well as during its running time. By adding its values under these keys LanRan v2 becomes able to start its infection files on each system launch.

When LanRan v2 ransomaware virus finishes the infection process of the system and encrypts valuable data, it drops two files that contain specially crafted ransom messages. The files are of different types. The first one is a text file called @___README___@.txt and the message it presents reads:

L_A_N_R_A_N R_A_N_S_O_M_W_A_R_E

#################################################################################

Attention! Attention! Attention! Your files has been encrypted By L_A_N—R_A_N_S_O_M_W_A_R_E

What is encryption?

Encryption is a reversible modification for security reasons but providing full access to it for
authorized users. To become an authorized user and keep the modification absolutely reversible (in

With the help of specific scripts, the ransomware replaces the desktop wallpaper with the second file which depicts a ransom message as well. So in case that your PC is infected by LanRan your desktop probably displays the following image:

The message depicted as an image reads:

According to hackers’ instructions, you need to transfer the amount of 0.5 BTC (3,678 USD at the moment of writing this article) to their wallet and then write them at lanran-decrypter@list.ru for the decryption key. However, as reported by security researchers, there is no registered case of infected user who has received a decryption key even after a successful ransom payment. This means that even cyber criminals cannot decrypt the data. So don’t rush to pay the ransom as this won’t help you to recover your .LanRan2.0.5 files.

Hopefully, security specialists will soon crack the code of the threat and release free decryption solution the moment they succeed to do it. Meanwhile, you could try to recover part of the corrupted .LanRan2.0.5 files with the help of alternative data recovery methods. If you wonder which these methods are, just navigate to the end of the article where you will find suggestions for some of the most efficient ones.

LanRan v2 Ransomware – Encryption Process

When all needed system modifications are implemented, LanRan v2 activates its built-in encryption module to fulfil its primary purpose. Supposedly like its previous version, the ransomware uses the sophisticated RSA-2048 algorithm to transform the original code of target files. Files with the following extensions are most likely to be corrupted by LanRan v2 :

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

After encryption each corrupted file has the specific extension .LanRan2.0.5 appended to its name while the information it contains is inaccessible. Below you can see an example of file encrypted by LanRan v2 crypto virus:

Remove LanRan v2 Ransomware and Restore .LanRan2.0.5 Files

Below you could find how to remove LanRan v2 step by step. To remove the ransomware manually you need to have a bit of technical experience and ability to recognize traits of malware files. Beware that ransomware is a threat with highly complex code that plagues not only your files but your whole system. So as recommended by security researchers you need to utilize an advanced anti-malware tool for its complete removal. Such a tool will keep your system protected against devastating threats like LanRan v2 and other kinds of malware that endanger your online security.
