An infection with the dangerous Meka virus ransomware virus leads to serious security issues. With our removal guide victims can try to restore and protect their computers.

The Meka ransomware is a new malware threat which aims to process certain user files with a strong cipher in order to render them inaccessible. The associated extension will be applied to the victim data and a ransomware note will be crafted in order to blackmail the users into paying the victims a ransomware decryption fee.

When the infection has been triggered the Meka ransomware will begin the malicious sequence. It can run different services and components depending on the built-in instructions by the hackers. In most cases, this will harvest information that can reveal information about the victims and the infected computers. This data is collected and sent to the hacker operators. If instructed so this can be done via a Trojan connection that will establish a secure connection to the operators making it possible for them to take over control of the Meka ransomawre infected hosts.

Other behavior can be included in the main engine such as the Windows Registry manipulations. It can create entries for itself and modify existing ones in order to cause performance issues, data loss and unexpected errors. As soon as all modules have completed running the ransomware engine will be called. It will start to process sensitive user data with the .meka extension. A lockscreen instance will be started in order to blackmail the users into paying the hackers a decryption fee. Lockscreen instances in some cases can block the ordinary interaction with the computer until the threat is completely removed.

Distribution of Meka Ransomware Virus

Meka virus virus is a new data locker ransomware that has been released in active attack campaigns against computer users worldwide. The threat could be utilizing common tactics of distribution to infect computer systems.

One of the easiest ways for the criminals to spread the payload of Meka virus ransomware is by attaching it to email messages that are later released in active attack campaigns. The method allows hackers to send the virus to large lists of potential victims. The attachments to malicious email spam messages usually have Word documents or other types of files which users open without hesitation. Once opened on a target host these compromised files trigger the ransomware payload and infect the device with Meka virus crypto virus. Another infection tactic related to emails is hyperlink inserted in the content of the messages. The links are usually labeled as leading to a familiar website or a file of user interest.

Computer criminals behind this new ransomware can be using malicious sites or download portals to distribute malware of different kinds, including Meka virus virus. A popular option is the use of infected documents which may be of different types ‒ spreadsheets, rich text documents, presentations and databases. They are modified to initiate the virus once the built-in scripts are run. Usually when the files are opened a notification will ask the users to run the macros (scripts). If this is done the infection follows.

The hacker-controlled sites are specialist portals that have been created either manually or automatically by the criminals behind Meka virus virus. They can either directly distribute the threat by initiating various scripts or automated operations or link to such instances. Redirects are usually caused by email interaction, ad networks or other browsing activity. However one of the main sources is the availability of browser hijackers. They are malicious add-ons made for the most popular web browsers ‒ Mozilla Firefox, Google Chrome, Internet Explorer, Opera, Microsoft Edge and Safari. Once installed they not only infect the users with the malware but also redirect the victims to a hacker-controlled site. Depending on the configuration the browser hijackers can also steal sensitive information such as any stored passwords, account credentials, history, bookmarks, form data and settings.

Impact of Meka Ransomware Virus

The Meka is a new ransomware sample that has just been announced in a security report. It is based on the code of the infamous STOP ransomware and distributed by an unknown hacker collective or an individual malicious actor.

The ransomware samples may begin the infection process by calling a data collection command. It has the ability to harvest data into that can be grouped into two categories:

  • Anonymous Data — The engine can collect various information that in the end is used to create an unique machine ID. This value is used to differentiate the infected computers from each other. The ID is made up of values associated with the installed hardware components, certain user settings and operating system variables. Using a special algorithm parts of all of these data is computed and the resulting ID is made.
  • Private Data — Information that can reveal the identity of the users is also collected by the engine. This may include strings such as their full name and personal details like their interests, phone numbers, email accounts and even stored passwords for online services. There is a serious risk of abuse as such pieces of information can be used to perform identity theft and financial abuse.

This information can then be used by the next module that is run during the behavior pattern — security bypass. It will scan the system for any running security software that can interfere with the virus payload. Common forms include anti-virus programs, virtual machine hosts and debug environments. When they are disabled the main ransomware engine will be able to infect all parts of the operating system.

Usually the Windows Registry changes will follow next. The engine can modify values belonging to the operating system and third-party applications. Depending on the type of Registry entries the resulting effects may be different — from troubles starting certain functions to serious performance issues.

The Meka virus can also be instructed into creating registry values for itself. This is done in combination with other modifications and is related to the persistent installation of the ransomware. The engine will be started automatically when the computer is powered on. An additional effect of this change is that the victims may not be able to able to boot into the recovery boot menu.

To prevent effective recovery the engine can be programmed to delete important system data. Contents includes Shadow Volume Copies and System Restore Points is deleted in order to make recovery much more difficult.

Some infections can also install a separate Trojan module. In most cases this will set up an encrypted connection to a hacker-controlled server which will be maintained during the infection’s duration. It would allow the operators to spy on the victim users in real-time, steal their files and also deliver additional viruses.

When all of the devised steps have been executed the actual encryption process will be started. The Meka like all previous versions will follow the typical infection pattern. This model will target specific user data according to a built-in list of target file type extensions that will be processed by a strong cipher. A typical list will feature the following file type extensions:

  • Backups
  • Databases
  • Archives
  • Videos
  • Music
  • Images

The resulting files will be renamed with the .meka extension. A ransom note will be dropped to extort a ransom fee for the infected files. It can be found in a text file called _readme.txt. Below you can see its conetent:

In fact, you only encourage hackers to continue spreading ransomware of this kind. Instead, you must remove the threat immediately, and only then look for optional ways to recover your data.

WARNING! Manual removal of Meka virus ransomware virus requires being familiar with system files and registries. Removing important data accidentally can lead to permanent system damage.
