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.
|Short Description||Even though in development stage, the virus may encrypt the files on the compromised computers, and asks to pay in BitCoin to get the files back.|

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:
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:

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.
