Description of Lukitus ransomware

Lukitus – the latest variant of Locky ransomware

Fragments of Lukitus ransomware

Lukitus is the newest version of Locky ransomware virus. It started spreading via malicious spam emails that include zip or rar attachments on August 2017. Ransomware aims at 458 different file types and encrypts them using RSA-2048 and AES-128 cryptography. To make them impossible to open and use, it also appends .lukitus file extension to each of them.

Lukitus ransomware also renames targeted files and creates total chaos. The virus uses a specific scheme to change filenames. It includes characters from the unique victim’s ID and random numbers or letters:

[first 8 characters of ID]-[next 4 characters of ID]-[next 4 characters of ID]-[4 characters]-[12 characters].lukitus

This crypto-malware not only takes these files to hostage, but makes their recovery nearly impossible. The virus is capable of deleting Shadow Volume Copies that are crucial for restoring files using third-party software. Therefore, users are offered to obtain the Locky Decryptor.

After the installation, Lukitus downloads two informational files on the computer:

  • ukitus.htm,
  • lukitus.bmp.

The BMP file is a threatening wallpaper that replaces affected computer’s background as soon as data encryption is over The HTM file is a ransom note that urges to visit Locky payment site and buy this shady tool for 0.5 Bitcoins.

Despite the fact this tool might be the only way to restore files, we do not recommend having business with cyber criminals. The success of the Locky should not trick you that hackers always keep their promise and allow victims to use their secret tool. Once they receive your $2000, they might disappear. So, instead of risking your money, focus on Lukitus removal.

In order to remove Lukitus from the PC you will need a strong and professional antivirus or malware removal program. We strongly recommend employing FortectIntego and cleaning your PC with the help of it.

Operation peculiarities of the ransomware

Once Lukitus gets access to the system, it connects to its Command and Control (C&C) server. In order to do so, it employs a Domain Generation Algorithm (DGA), which allows using numerous different domains. Currently, it’s known that ransomware connects to these addresses, but please do not think about visiting them:

  • http: // kokalgfsnepogq [.] ru / imageload.cgi
  • http: // kljidoejmiqx [.] org / imageload.cgi
  • http: // sorqjivpyfrwlo [.] Click / imageload.cgi
  • http: // jcanepkjyu [.] biz / imageload.cgi
  • http: // dxeqiniexovy [.] org / imageload.cgi

When the connection is established, ransomware downloads malicious files to the system and runs them. Lukitus can inject malicious codes to legitimate system processes, modify Windows Registry and cause other system changes, such as deletes Shadow Volume Copies.

Of course, the most important task is data encryption, which is completed as soon as the virus strengthens its presence. Due to these system changes, you have to get rid of Lukitus immediately. Otherwise, your computer becomes vulnerable.

Malspam spreads Lukitus ransomware in ZIP and RAR archives

Malicious emails that include Lukitus payload are spreading with the help of Necurs Botnet and the BlankSlate malware. Researchers spotted more than 1000 different emails that include infected ZIP or RAR archives. The majority of infections were carried from July-August2017.rar file.

The malicious archive is attached to an ordinary email that asks to check the documents. However, this attachment include JS file that executed malware on the PC as soon as a user opens it. Of course, this file is obfuscated and looks like MS Word or Excel file, PDF, or other safely looking file.

Currently, researchers spotted few active email campaigns that use these subject lines:

  • Emailing [random letters and numbers]
  • < No Subject >

Therefore if you receive an email with such subject line, you should not open it; especially, you should not open attached documents or click on provided links. If you have opened an unknown email that urges to check the attachment, you have to make sure that it’s actually safe to do it.

How to prevent from getting ransomware

Securely connect to your website wherever you are

Sometimes you may need to log in to a content management system or server more often, especially if you are actively working on a blog, website, or different project that needs constant maintenance or that requires frequent content updates or other changes. Avoiding this problem can be easy if you choose a dedicated/fixed IP address. It's a static IP address that only belongs to a specific device and does not change when you are in different locations. 

VPN service providers such as Private Internet Access can help you with these settings. This tool can help you control your online reputation and successfully manage your projects wherever you are. It is important to prevent different IP addresses from connecting to your website. With a dedicated/fixed IP address, VPN service, and secure access to a content management system, your project will remain secure.

Reduce the threat of viruses by backing up your data

Due to their own careless behavior, computer users can suffer various losses caused by cyber infections. Viruses can affect the functionality of the software or directly corrupt data on your system by encrypting it. These problems can disrupt the system and cause you to lose personal data permanently. There is no such threat if you have the latest backups, as you can easily recover lost data and get back to work.

It is recommended to update the backups in parallel each time the system is modified. This way, you will be able to access the latest saved data after an unexpected virus attack or system failure. By having the latest copies of important documents and projects, you will avoid serious inconveniences. File backups are especially useful if malware attacks your system unexpectedly. We recommend using the Data Recovery Pro program to restore the system.
