Kaenlupuf Ransomware Description

The Kaenlupuf Ransomware is a newly discovered malware threat which has an interesting name. According to the initial research it is short for KAsi ENkrip LU PUnya and it appears to be of Malaysian origin. Like other similar threats it appears to be signed by a well-known signature, this time the false copyright bears tha name “Microsoft Windows Operating System”.

The virus is of unknown origin and is probably developed by an unknown hacker or a collective. In recent times it has been a popular strategy to devise a local virus and then develop a global one which can be launched around the world. These types of viruses are carefully laid out to affect computer targets in specific regions or targeting predefined languages. This strategy can be achieved using two methods:

  1. Target Campaigns – The hackers create a list of predefined targets that are located geographically in the same country or region.
  2. Target Selection – The viruses are launched globally and its code includes a module which runs predefined checks to ensure that the only victims that pass the checks get infected. Variables include location and language options and etc.

The analysis shows that the virus follows a predefined set of checks that it makes before proceeding further with the infection:

  1. The virus checks for a predefined Windows version.
  2. The engine checks for the availability of predefined files with certain file attributes in place.
  3. An expiration date check is made.

Only after these three requirements are met the virus engages further. Otherwise it deletes itself.

Upon infection the virus engages in the usual behaviour patterns by starting its encryption engine which target user data. At the moment we do not have information about which extension is used to rename the affected files. Once this is complete a ransomware note is crafted in a kaenlupuf-note file. Its contents are written in Malaysiasn and a machine-translated version reads the following:

Its interesting to note that the ransomware message contains an ASCII Art image which is reminiscent of the older generation of pirate and hacker notes. This probably means that the developers are of an older generation or have been inspired by them.

Further modifications can lead to other options that are available:

  • Additional Malware Infections – The virus may include a payload delivery module which can lead to additional virus infections.
  • Windows Modification – Viruses such as this one can modify key system settings, modify and add registry values. Such actions can lead to computer errors that may disable the ordinary functions of the infected machines.
  • Screenlocker Module – Viruses of this type frequently employ screenlockers which obstruct the normal use of the computer until the ransomware has been deleeted completely. This function also serves as a way to make the users pay the ransom fee.
  • System Information Harvesting – The virus can transmit information about the infected host to the remote attackers. Advanced versions can also be used to harvest stored browser cookies, history and accounts.

The initial analysis shows that the virus interacts with several DLL files:

ADVAPI32.dll, CRYPT32.dll, KERNEL32.dll, MSVCP110.dll, PSVCR110.dll, NETAPI32.dll, Normaliz.dll, SHELL32.dll, SHLWAPI.dll, urlmoon.dll, USER32.dll, WINNET.dll, WLDAP32.dll and WS2_32.dll.

Like other similar threats the virus assigns an unique ID to every infected host. According to the malware researchers the hackers behind the threat are a part of a secret collective or group called “KAENLUPUF”. Network commmunication is done using a public key which means that the hackers have taken the step of securing the transfer.

According to the researchers the virus is under development at the moment.

Kaenlupuf Ransomware Distribution

The initital security analysis shows that the first malware samples were discovered in March 2017. The first mentions of it were made in January 2017 in various hacker forums. At the moment it is primarily distributed among Malaysian users.

As the ransomware is still in development we have no information about the ways it will be distributed. However we assume that the hackers are going to use the most popular infection strategies which include the following:

  • Email Spam Campaigns – Hackers typically employ phishing scams which are a common type of social engineering. These attacks pose as messages from legitimate companies or government organizations and typically send out infected documents. They feature dangerous macros which deliver the dangerous payload via scripts. Other methods include links in the body of the emails or the document itself.
  • Dangerous Scripts – Hackers use infected browser hijackers, dangerous scripts and ad networks to redirect the victims into download where viruses are hosted.
  • Download sites and P2P Networks – Hackers typically employ hacker-controlled sites or hacked download portals and BitTorrent servers (trackers) to distribute viruses. In the majority of cases the viruses pose as legitimate installers of famous applications and games.
  • Bundled Installers – Kaenlupuf Ransomware like other similar threats is often bundled with software installers. Depending on the package the user may opt to prevent its installation by modifying the installation settings. However in most cases the virus is hidden and it is automatically installed once the rogue setup application is complete.
