THREAT REMOVAL

Article created to give insight on the malware called Kaenlupuf which is still in development and show how to remove it and decrypt files if your computer has been infected.

A ransomware virus created solely for Malaysian-speaking users, calling itself Kaenlupuf has been reported to be using AES-128 to encrypt files on computers which it can infect. The ransomware infection drops multiple files on the compromised computers, including a file indicating that the virus is version 1.0b. The virus uses a fake name – Microsoft Network Realtime Inspection Service and several others. In case this virus hits the wild and infects, we have prepared instructions that will help you remove it from your computer and ways to use the decryptor for Kaenlupuf to unlock all your files for free.

Kaenlupuf Virus – How May It Infect

The virus may be spread, depending on what the one who is infecting with it decides. Usually, a big chunk of ransomware viruses out there do not limit themselves with one infection method. They use fake program installers, infected such, fake game cracks and patches and other activators that may be uploaded as torrents on websites. Sometimes, even PUPs (potentially unwanted programs) are used in order to cause an infection via malicious pop-ups, but very rarely.

The most dominant form of infection however that may spread Kaenlupuf in the future if the cyber-crooks behind this virus decide to update it, may be e-mail spam. Usually, such spam messages are sent out very cheaply via spam bots to a pre-set list of e-mail addresses of real users. This method is very effective and can increase the infection ratio of this virus very fast. To succeed in the infection, the criminals use social engineering (deceptive) techniques, like pretend that either a malicious web link or attachment in the sent e-mail is completely legitimate. To do this, they often claim that this is a document that has more information on a problem that the user has (suspicious bank activity, invoice for the purchase, the user hasn’t made and other). These tricks easily fool inexperienced users into opening e-mail attachments and hence becoming infected.

Kaenlupuf Virus – More Information

When an infection by this virus has been performed, it begins to create multiple files on the compromised computers. The files are primarily executable files, named:

  • Netsvc.exe
  • Kaenlupuf-note
  • Ajaw-rsa.exe

The virus also drops a very interesting ransom note, with asci art and elements of retrowave artwork:

The ransom note is written entirely in Malaysian, but the message in it is the same like most ransomware viruses out there. It roughly translates to the following:

“IMPORTANT FOR YOU – READ
First of all, we congratulate you on choosing one of the best file protection from external threats.
We understand that you need the files immediately. We will provide a special package at an affordable price for only 1 bitkoyn.
Are surprised by our offer? So what are you waiting for, register your bitcoin now to get a valuable addition to your important files.
The longer you wait, the greater the amount. Your files are protected by the RSA-2048 algorithm. Very good and interesting, is it not?

To return your files, follow these steps:
1. Register your account in the google-purse at the following URL:
Https://blockchain.info/wallet/
2. Use our bitcoin-address to transfer the payment:
173MLPGRWdc6z91gQXBCHYVTkqTR9tMABb
3. The amount of payment is as follows:
1 BTC
4. Be sure to report your ID when making a transaction.
YOUR TOKEN ID”

Kaenlupuf Ransomware’s Encryption

For the encryption of the files, malware researchers report that this virus may take advantage of the AES-128 encryption algorithm. It is used to replace bytes of a working file’s data with encrypted symbols. This acts as if it scrambles the file and the file becomes similar to corrupt. It does not have an icon and can no longer be opened by any type of software.

The files that have been encrypted by this ransomware infection may usually be important files that are often used, like:

  • Microsoft Office Documents.
  • Adobe Documents.
  • Image files.
  • Archive files.
  • Files associated with virtual drives.
  • Database files.
  • Audio files.
  • Videos.

Here is a method in few easy steps that should be able to uninstall most programs. No matter if you are using Windows 10, 8, 7, Vista or XP, those steps will get the job done. Dragging the program or its folder to the recycle bin can be a very bad decision. If you do that, bits and pieces of the program are left behind, and that can lead to unstable work of your PC, errors with the file type associations and other unpleasant activities. The proper way to get a program off your computer is to Uninstall it. To do that:


1. Hold the Windows Logo Button and "R" on your keyboard. A Pop-up window will appear.

3. This will open a window with all the programs installed on the PC. Select the program that you want to remove, and press "Uninstall"
Follow the instructions above and you will successfully uninstall most programs.


Step 3: Clean any registries, created by Kaenlupuf on your computer.

The usually targeted registries of Windows machines are the following:

  • HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
  • HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
  • HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
  • HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce

You can access them by opening the Windows registry editor and deleting any values, created by Kaenlupuf there. This can happen by following the steps underneath:

1. Open the Run Window again, type "regedit" and click OK.


2. When you open it, you can freely navigate to the Run and RunOnce keys, whose locations are shown above.


3. You can remove the value of the virus by right-clicking on it and removing it.
Tip: To find a virus-created value, you can right-click on it and click "Modify" to see which file it is set to run. If this is the virus file location, remove the value.

IMPORTANT!
Before starting "Step 4", please boot back into Normal mode, in case you are currently in Safe Mode.
