.lilocked files virus is a ransomware from an unknown hacking collective aiming to infect as many users as possible. Due to the fact that there is currently no information available about the distribution methods we anticipate that the most popular ones are to be used. The virus may start different malicious components and in the end will encrypt target user data with a strong cipher, resulting in them being inaccessible and renamed with the .lilocked extension. The victims will be blackmailed into paying the hackers a “decryption fee”.

.lilocked Ransomware – Update October 2019

There is evidence that LiLocked is currently targeting only Linux-based systems but the method of infection is still unknown. According to information spotted on a Russian forum, the ransomware operators could be targeting systems running outdated Exim software.

It is also highly possible the ransomware manages to get root access to infected servers. Infected servers have their files encrypted, and have the .lilocked file extension. It is important to note that the ransomware does not encrypt system files. Instead, it encrypts HTML, SHTML, JS, CSS, PHP, INI files, as well as and several image file formats. This fact means that the compromised servers continue to run normally.

.lilocked Files Virus – Update September 2019 Second Attacks

September 2019 saw the release of a second attack carrying the .lilocked files virus. This campaign is noticeably lower in volume and targets specific networks. This gives us reasons to believe that it is orchestrated by a single hacking group. The focus appears to be Linux systems. The exact intrusion strategy is unknown at this stage however it is believed that it is still done by vulnerabilities in the EXIM service. The other popular tactics that are still possible include the following:

  • Phishing Tactics — The sending of bulk SPAM e-mail messages and the construction of dangerous sites that resemble the portals and landing pages of legitimate companies and services. Whenever they are accessed or interacted with the associated .lilcked files virus will be deployed.
  • Browser Extensions — The so-called “browser hijackers” which are dangerous plugins that are made compatible with most of the popular browsers. They can feature the virus infection code and will install it as soon the extensions are deployed.
  • Bundle Installers — The hackers can create application installers of popular software that are often installed by end users.

The .lilocked files virus and its ransomware variant in this version will not encrypt system files, but target image data and ile suc has HTML, SHTML, CSS, JS, PHP and INI. This gives security researchers reasons to believe that the attacks are set mainly against servers. The analysis of the made infections shows that a large part of them are already indexed on search engines like Google. However a significant portion of the newly infected hosts are still not indexed making it harder to estimate the total number of compromised hosts. It is believed that the hacking group are specifically targeting CMS-powered sites:

  • WordPress
  • Magento
  • Drupal
  • Joomla

.lilocked Files Virus – Update September 2019

New Google data reveals that there are more than 6,000 search results about web servers encrypted by Lilocked ransomware, with all files encrypted with the .lilocked extension. This means that the ransomware is being spread in a new campaign, and is currently targeting servers. Some users report that the attacks were initiated by an Exim exploit. However, other infection vectors are also possible.

.lilocked Files Virus – Detailed Description

The .lilocked files virus can be spread using popular distribution techniques in order to infect as many victims as possible. If a large-scale campaign is planned then multiple strategies can be used at once. One of the most common activities is the coordination of phishing email-based attacks — the hackers will send out messages that appear as being sent by a well-known company or service. The other alternative is the creation of hacker-controlled web sites. They are hosted on similar sounding domain names that may further confuse the visitors into interacting with them.

The .lilocked files virus code can be embedded across various file carriers. This can include all popular document file formats: spreadsheets, presentations, text files and databases. When they are opened by the victims a prompt will appear asking the victims to enable the built-in code. If this is done then the virus infection will be started. The other file carrier is the malware app installer — the hackers will take the legitimate setup files of popular programs and modify them with the virus installation code. They are then distributed over the phishing emails, sites and even file-sharing networks such as BitTorrent.

Interaction with browser hijackers can also lead to the file encryption viruses. They are dangerous plugins made for the most popular web browsers and can often be found on the associated repositories as uploaded by the hackers via fake or stolen developer credentials and user reviews.

At the onset of infection the .lilocked files virus will start its built-in sequence of malicious actions. Most of the virus infections will begin with a data harvesting module which will gather sensitive information about the machines and the users themselves. As a consequence every infected host will have its own ID that is based on an unique footprint. The collected information about the machines will be used in order to generate an unique footprint for each machine. The gathered information can be used further in order to scan the computers for any installed security software either in memory and on the hard disk space. Usually this includes the following: anti-virus programs, firewalls, sandbox environments, virtual machine hosts and etc.

What will follow next in most cases is the setting of the .lilocked files virus as a persistent threat. This means that it will be started every time the computer is powered on, to make it more difficult to remove them the engine will block all access to the recovery boot options.

If any Windows Registry changes are part of the infection then the victims may experience data loss, unexpected errors and issues when accessing certain functionality or applications. Such viruses are also adept at identifying and deleting sensitive files such as shadow volume copies, backups and restore points. As soon as the all components have finished running the actual file encryption operations will begin. The .lilocked files virus will search for data such as the following: backups, databases, documents, archives, multimedia files and etc. All of the affected data will receive the .lilocked extension and in order to blackmail the victim users into paying the hackers a decryption fee.

.lilocked Files Virus – What Does It Do?

The .lilocked Files 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 .lilocked Files 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
