Remove Lilocked ransomware (Virus Removal Guide) - Sep 2019 update

removal by Gabriel E. Hall - - | Type: Ransomware

Lilocked ransomware is a cryptovirus that targets Linux-based servers and runs Exim software to get on the system

Lilocked ransomwareLilocked ransomware is the virus that locks files and demands payment on a program window and in txt file. Lilocked ransomware, also known as Lilu ransomware, is a threat that possibly spreads through outdated WordPress sites or at least researchers speculate that this is one of the un-common vectors for spreading this particular cryptovirus.[1] There is a need for further investigation since the threat is not related to any previously known viruses. Using the AES encryption algorithm, this virus encrypts files on websites and servers and then requires ransom in Bitcoin that goes from 0.001 to 0.01, or even more for alleged file recovery. All those files get marked using .lilocked extension and cannot be opened or used from there. 

Once Lilocked ransomware virus is done with the file locking process, the ransom note named #README.lilocked.txt gets placed in each folder where the cryptovirus encodes data.[2] The file contains a ransom note, additional information about the encryption and the victims' ID. Then the user gets redirected to the portal, which displays a demand for payment with a particular amount of money needed for receiving the data recovery key. Some reports state about the ransom that goes to $300 and more in Bitcoin. According to recent reports, this threat encrypted more than 6 700 servers already.[3]

Name Lilocked ransomware
Type Cryptovirus
Target This damaging ransom-demanding and file-encrypting cyber threat is known to target and attack those machines which are running the Linux operating system

Possible damage  Files get encrypted, possibly permanently and cannot be opened or used properly, info-stealing or damaging malware can get installed and corrupt the device even more
Already known  According to various cybersecurity news reports, this virus has already encrypted thousands of Linux-based servers, some of which are included in Google search results
Distribution The ransomware virus might be capable of spreading via outdated WordPress services or outdated software such as Exim. In addition, other malware, spam email attachments, malicious files, vulnerable RDP can carry the malicious payload
Elimination  Get the anti-malware tool and remove Lilocked ransomware. Clean the damage using Reimage Reimage Cleaner Intego. Also, do not try to eliminate the cyber threat on your own as there is a big risk of creating harm

Lilocked ransomware is a fairly new cryptovirus that came to the light recently and has no association with previously discovered malware. This program infiltrates the system and encodes stored data. It doesn't affect system files and mainly focuses on files in HTML, SHTML, JS, CSS, PHP, INI, and various image file formats.

Since there is no particular number of victims and the initial entry point of the malware remains unknown, all the facts are generic and based on the functionality and similarities to the common cryptovirus. Lilocked ransomware can victimize even more people than those 6.700 infected servers already known for the researchers.

It is believed that Lilocked ransomware uses outdated WordPress site on the server as a vector of spreading the threat. But this is only an assumption with no particular payload or sample to analyze or confirm. Nevertheless, the virus starts its processes immediately after infiltration and delivers the following ransom note for the victim:




When the provided link is clicked, Lilocked ransomware shows a website that prompts the victim to enter the provided key and then asks them to pay the particular amount in Bitcoin. Particular attempts of malware researchers revealed that criminals demand up to 0.03 BTC – more than $300. The transfer should be made in the Electrum wallet, and then the victim should get encrypted files recovered.

Lilocked ransomware virusLilocked ransomware is a cryptovirus that focuses on encryption process once it gets on the system, network or even server.

Lilocked ransomware has been detected by tens of different AV engines as a malicious piece of software. However, the detection name might differ each of them when you use another antimalware tool. According to Virus Total virus examination, the ransomware virus is most commonly spotted by these detection names:[4]

  • Other:Malware-gen [Trj] (AVG and Avast).
  • Trojan.Linux.Lilock.A (Bitdefender).
  • Trojan.Linux.Lilock.A (B) (Emsisoft).
  • HEUR:Trojan-Ransom.Linux.Lilock.a (Kaspersky).
  • Ransom.Lilocked (Symantec).

Reports claim about numerous servers infected with the Lilocked ransomware strain

It is known that Lilu is targeting web servers since the middle of July this year but some of the samples obtained already are related to websites. There is no pattern in particular that can reveal more information about the threat or its developers. However, it is common to believe that Lilocked ransomware uses exploits to gain access to wanted systems.

Even though researchers have discovered that almost 7,000 affected servers remain in the Google search results, specialists have been guessing that there is a much bigger number of infected systems from which the majority might not even be saved in the Google search database.

Particular Exim EK is possibly used to spread on web servers in this campaign.[5] Various pages get delivered on the same web page that the virus redirects to. However, clicking on them can lead to more severe malware than Lilocked ransomware itself. For example, you might get infected with cryptocurrency mining viruses.

Lilocked malwareLilocked malware is a ransomware strain that might be capable of spreading via outdated WordPress websites

You need to remove Lilocked ransomware as soon as possible, and symptoms get noticed because info-stealers can obtain personal data and lead to serious privacy or identity issues. Pages where the key is required opens, other instructions also get displayed for the victim. All this content makes people more scared and tricks them into paying the hefty mounts.

However, experts[6] never recommend to pay and instead offers to perform Lilocked ransomware removal instead. Lilu virus developers only care about your money and have no mercy for their victims. There might be many speculations about the threat, but further analysis is needed and a sample of the virus required for that. You can contact Michael Gilespie on Twitter to provide any information.

Ransomware creators have many methods of spreading crypto-demanding malware 

Ransomware infections are known to be capable of spreading through outdated web services such as WordPress or particular software, for example, Exim, that is also out of date. However, these are only just a few ways of how ransom-demanding malware is capable of reaching the targetted computer system.

In addition, it is common for cybercriminals to distribute such type of threats by hacking unprotected RDP configuration and the TCP 3389 port is known to be one of the most vulnerable to hacking attempts. Furthermore, malware developers might take advantage of security flaws (especially when the computer does not include an antivirus tool or it has not been updated regularly).

Furthermore, you can easily meet ransomware through deceptive downloads, botnets, and fake updates, shady download sites are all used to deliver file-locking malware. However, the primary method still is spam emails and infected file attachments filled with malicious macros. 

Cybercriminals are very likely to pretend to be from well-known shipping companies, e.g. FedEx or DHL, and tend to send random people order confirmation messages. Usually, the emails come with a particular link which clicked executes the malware or a suspicious attachment that also holds malicious payload.

Protect yourself from possible malware attacks

The best way to stay safe and keep your computer system undamaged from ransomware and similar malware attacks is to pay attention to both manual and automatical security measures required. First of all, ensure that antivirus protection is installed on your machine and operating properly. For good functioning, you need to make sure that regular updates are always completed.

Continuously, keep yourself away from suspicious third-party networks that are marked as unsafe or just cause the feeling of concern. The most avoidable sources should be p2p ones such as The Pirate Bay, various adult-dating and adult-content websites, gambling, and online-gaming networks. If you are looking for a particular product, get it from a reliable source and always check the developer's reputation.

Last but not least, you have to learn how to verify misleading email messages. What you have to do is always check the sender and make sure that the letter does not come from a bogus person. Furthermore, go through the entire text and search for grammar mistakes as no reliable company will leave their texts full of mistakes. Finally, all received attachments should be scanned with antimalware before opening them.

Get rid of the malicious Lilocked ransomware virus with anti-virus protection software

Lilocked ransomware virus is known for attacking servers, websites and already encrypted thousand of servers and data stored on them. You need to react as soon as possible if you want to avoid permanent damage and the possible loss of money. Since there's no pattern – the servers are random, no one is immune or safe.

You shouldn't pay the ransom and remove Lilocked ransomware instead. Gather encrypted files for the potential decryption later on and rely on file backups for restoring processes. You can also check methods listed below for file recovery if needed.

However, for the most important process- Lilocked ransomware removal, you need to get anti-malware tool like Reimage Reimage Cleaner Intego, SpyHunter 5Combo Cleaner, or Malwarebytes and wipe the system down.

Bonus: Recover your data

Guide which is presented above is supposed to help you remove Lilocked from your computer. To recover your encrypted files, we recommend using a detailed guide prepared by security experts.

If your files are encrypted by Lilocked, you can use several methods to restore them:

Data Recovery Pro is a tool for data restoring functions

Use this software for bringing your files and data back after Lilocked ransomware encryption

  • Download Data Recovery Pro;
  • Follow the steps of Data Recovery Setup and install the program on your computer;
  • Launch it and scan your computer for files encrypted by Lilocked ransomware;
  • Restore them.

Use Windows Previous Versions feature for data restoring

If you have used a System Restore, you should give this method a try

  • Find an encrypted file you need to restore and right-click on it;
  • Select “Properties” and go to “Previous versions” tab;
  • Here, check each of available copies of the file in “Folder versions”. You should select the version you want to recover and click “Restore”.

Try ShadowExplorer for file recovery

If the virus did not get in time to eliminate Shadow Volume Copies of your encrypted files, you can use this software

  • Download Shadow Explorer (;
  • Follow a Shadow Explorer Setup Wizard and install this application on your computer;
  • Launch the program and go through the drop down menu on the top left corner to select the disk of your encrypted data. Check what folders are there;
  • Right-click on the folder you want to restore and select “Export”. You can also select where you want it to be stored.

There is no official decryptor for Lilocked ransomware

Finally, you should always think about the protection of crypto-ransomwares. In order to protect your computer from Lilocked and other ransomwares, use a reputable anti-spyware, such as Reimage Reimage Cleaner Intego, SpyHunter 5Combo Cleaner or Malwarebytes

Access your website securely from any location

When you work on the domain, site, blog, or different project that requires constant management, content creation, or coding, you may need to connect to the server and content management service more often. It is a hassle when your website is protected from suspicious connections and unauthorized IP addresses.

The best solution for creating a tighter network could be a dedicated/fixed IP address. If you make your IP address static and set to your device, you can connect to the CMS from any location and do not create any additional issues for server or network manager that need to monitor connections and activities. This is how you bypass some of the authentications factors and can remotely use your banking accounts without triggering suspicious with each login. 

VPN software providers like Private Internet Access can help you with such settings and offer the option to control the online reputation and manage projects easily from any part of the world. It is better to clock the access to your website from different IP addresses. So you can keep the project safe and secure when you have the dedicated IP address VPN and protected access to the content management system.

Backup files for the later use, in case of the malware attack

Computer users can suffer from data losses due to cyber infections or their own faulty doings. Ransomware can encrypt and hold files hostage, while unforeseen power cuts might cause a loss of important documents. If you have proper up-to-date backups, you can easily recover after such an incident and get back to work. It is also equally important to update backups on a regular basis so that the newest information remains intact – you can set this process to be performed automatically.

When you have the previous version of every important document or project you can avoid frustration and breakdowns. It comes in handy when malware strikes out of nowhere. Use Data Recovery Pro for the data restoration process.
