.Lazarus virus is a new malware threat that is descendant from the Ouroboros ransomware which is being sent to targets across the world. It is a complex ransomware that is distributed via various methods. It can lead to many serious system issues and can even install other malware threats. When it has completed running all of its modules it will proceed with the file encryption making sensitive user data inaccessible. The victims will be left with .Lazarus extension encrypted data and a ransomware note and/or a lockscreen instance.

.Lazarus virus – Detailed Description

The .Lazarus virus is a new threat based on the Ouroboros ransomware family. It is anticipated that this virus will be modeled after the typical model used by ransomware. There is no information available about the hacker or the criminal group behind it. Due to it being a newer iteration of a well-known threat we expect that it will follow the same distribution techniques as its predecessors. This includes the sending out of phishing messages via emails and the construction of hacker-made sites that attempt to manipulate the victims into believing that they are receiving notifications from a legitimate service or company. When the users interact with any of them the associated .Lazarus virus engine will be started.

In addition the hackers can also embed the necessary installation scripts into file carriers — they can be various executables or documents that will lead to the virus infection once the users interact with them. A prime example is the inclusion of the virus macros across all popular document formats: text files, spreadsheets, presentations and databases. The other popular technique relies on the inclusion of the associated virus infection code in application installers. The hackers will generally target popular software that is frequently obtained by end users.

The .Lazarus virus can be contained also by browser hijackers which are dangerous plugins made for most of the popular web browsers. The criminals will post these extensions to the respective plugin reposoitories. They are commonly posted with fake user reviews and developer credentials and attempt to manipulate the victims into believing that they are installing an useful extension.

As soon as the .Lazarus virus is installed on a given computer it will execute its built-in sequence of malicious components. A common infiltration with ransomware of the Ouroboros family of threats may include any of the following:

  • Data Retrieval — The .Lazarus virus can be set to extract a lot of sensitive information from the compromised hosts. This can include a list of the installed hardware components which is used to create a complete profile of the infected computers. What’s particularly worrying is when this module is programmed to collect information about the victims: the data can be used for various crimes such as identity theft and financial abuse.
  • Persistent Threat Installation — If installed in an appropriate way the .Lazarus virus can be deployed as a persistent threat. This means that it will modify the boot options in order to start itself automatically as soon as the computer is powered on. It can also block access to the recovery boot options making it very hard to follow the usual manual user recovery guides.
  • Windows Registry Changes — The .Lazarus virus can create new strings or edit out existing ones in the Windows Registry. The consequences of this action can lead to severe performance issuses, the inability to access certain functions and data loss.
  • Additional Malware Delivery — The made infections can be used to deploy other viruses to the hosts: Trojans, cryptocurrency miners and etc.

As soon as the .Lazarus virus is deployed onto a given host and has executed all of its built-in modules it will start with the file encryption process. It will be based on a built-in list of target file type extensions that are to be affected: documents, multimedia files, backups, archives, databases and etc. All of the victim files will be renamed with the .Lazarus extension. A ransomware note will be crafted to manupulate the victims into paying the hackers a “decryption restore fee”.

.Lazarus virus – What Does It Do?

The .Lazarus virus is a crypto virus programmed to encrypt user data. As soon as all modules have finished running in their prescribed order the lockscreen will launch an application frame which will prevent the users from interacting with their computers. It will display the ransomware note to the victims.

You should NOT under any circumstances pay any ransom sum. Your files may not get recovered, and nobody could give you a guarantee for that.

The .Lazarus virus cryptovirus could be set to erase all the Shadow Volume Copies from the Windows operating system with the help of the following command:

→vssadmin.exe delete shadows /all /Quiet

If your computer device was infected with this ransomware and your files are locked, read on through to find out how you could potentially restore your files back to normal.
