Takahiro Locker Ransomware Description

The Takahiro Locker ransomware has recently been spotted by security researchers and is one of the newest malware that have a ransom note written in a language other than English. Despite the fact that the instructions are in Japanese, there have been a variety of campaigns that deliver the threat in countries other than Japan.

Takahiro Loader has a rather long initialization process in comparison to other threats by following a sequence of commands. The first thing that it does is to create a new folder in the %User Temp%\Google\Chrome location where the ransomware copies itself as the Update.exe binary. This is made to fool the users into thinking that its an update for the Google Chrome web browser. Two registry entries are also added to the Windows registry:

  • HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run Google Chrome Update Check = %User Temp%\Google\Chrome\Update.exe
  • HKEY_CURRENT_USER\Software\Google\Update\SEND SENDING = [random address]

The first registry entry creates an auto-start mechanism in the Windows operating system, making the ransomware execute upon every boot of the system. The second entry is probably a variable address to which harvested information about the infected machines are send.

The actual start of the encryption process is started when a notification message displaying the “WARNING RUNNING KILL ME!” text. This step has been placed by the hackers to scare the users while the ransomware has locked its process and has started to encrypt the target victim files. The affected data are the most popular documents and audio & videos. As of today we do not have the complete list yet yet. Some of the following extensions are affected:

txt, .jpg, .png, .bmp, .zip, .rar, .torrent, .7z, .sql, .pdf, .tar, .mp3, .mp4, .flv, .lnk, .html, .php

When the encryption process has completed another notification screen is displayed which shows the ransom note in Japanese. A rough translation of it reads the following:

Hello,
this is Tang, a Lawyer.
You have made an illegal file transfer, so I have locked your PC.
To unlock your files, you need to pay 3 Bitcoins within 3 days.
You need to have 30,000 Japanese Yen, to transfer them to Bitcoins and send them to me.
If you don’t pay within 3 days, the key for decryption will be deleted from where the server is stored and the data of your PC can no longer be returned.
Click the button “Next”.

Like other ransomware variants the hackers request the sum of 3 Bitcoins which is unusually high for a typical ransomware strain. A time limit of 3 days is also imposed on the user to try to extort them into paying the sum.

What’s interesting about the Takahiro Locker ransomware is that it does not damage files found in the following locations:

  • Windows
  • Steam
  • Origin
  • Program Files
  • Recycle Bin

In addition the ransomware deletes all Shadow Volume Copies from the Windows operating system to prevent file restoration.
