Luceq ransomware removal instructions
What is Luceq?
This malicious program belongs to the Djvu ransomware family and was discovered by Michael Gillespie. Luceq is a ransomware type program that is designed to encrypt data and make files unusable unless a ransom is paid to the cyber criminals who developed it. Like most computer infections of this type, Luceq renames each encrypted file by adding a new/additional extension. In this case, it adds ".luceq". For example, "1.jpg" becomes "1.jpg.luceq". Luceq generates a ransom message within a text file called "_readme.txt". This can be found in all folders that contain encrypted files.
The "_readme.txt" file/ransom message states that all files were encrypted, and to decrypt them, a specific decryption tool is required. Cyber criminals demand $980, however, if contacted within 72 hours after encryption, the cost drops to $490 (i.e. a 50% discount for people who contact them within three days). Luceq developers also mention that it is impossible to decrypt files without using their decryption tool. Therefore, users with computers infected by this ransomware and wishing to restore their files must purchase a decryption tool. As 'proof' that they have the tool, these cyber criminals offer free decryption of one file. In any case, Luceq victims are urged to contact developers via the email@example.com or firstname.lastname@example.org email address. Unfortunately, most cyber criminals cannot be trusted - they provide no decryption tools even if their ransom demands are met. People who send money (usually in a cryptocurrency) become victims of a scam. Most ransomware-type programs encrypt data using cryptography algorithms (symmetric or asymmetric) that make decryption impossible without using the correct tool. In most cases, the only free way to regain access to files is to restore them from a backup created prior to the ransomware infection.

Luceq is very similar to many other programs of this type such as P3rf0rm4, Luces, and Metan. Typically, these programs share two main similarities: they encrypt data and create ransom demand messages. Any differences are usually cryptography algorithm used to encrypt data and cost of decryption tool (or key). These ransomware-type programs usually are impossible to 'crack' and, therefore, decryption without having to contact cyber criminals and buy decryption tools is possible only if the ransomware is still in development or contains bugs/flaws. Therefore, maintain regular backups and store them on remote servers or storage devices that are not connected to computers.
How did ransomware infect my computer?
|Threat Type||Ransomware, Crypto Virus, Files locker.|
|Symptoms||Cannot open files stored on your computer, previously functional files now have a different extension (for example, my.docx.locked). A ransom demand message is displayed on your desktop. Cyber criminals demand a ransom payment (usually in Bitcoins) to unlock your files.|
|Distribution methods||Infected email attachments (macros), torrent websites, malicious ads.|
|Damage||All files are encrypted and cannot be opened without paying a ransom. Additional password-stealing trojans and malware infections can be installed together with a ransomware infection.|
To eliminate Luceq virus our malware researchers recommend scanning your computer with Spyhunter.
How to protect yourself from ransomware infections?
If an email contains an attachment or web link and is received from an unknown/untrustworthy email address, or the email is irrelevant, do not open the presented attachment. All installed software should be updated using implemented functions or tools provided by official software developers. Third party updaters should not be trusted. Download software from trustworthy, official websites. Avoid third party downloaders and other sources mentioned above. Software 'cracking' tools cause computer infections and are illegal. Therefore, do not use them. Another way to keep your computer safe is to have a reputable anti-spyware or anti-virus suite installed. These tools can detect and eliminate threats before they can do any damage to the operating system or files stored on the computer. If your computer is already infected with Luceq, we recommend running a scan with Spyhunter for Windows to automatically eliminate this ransomware.

As with most of ransomware from the Djvu family, Luceq also displays a fake Windows update pop-up during encryption:
IMPORTANT NOTE! - As well as encrypting data, ransomware-type infections from the Djvu malware family also install a trojan-type virus called AZORult, which is designed to steal various account credentials. Furthermore, this malware family is designed to add a number of entries to the Windows hosts file. The entries contain URLs of various websites, most of which are related to malware removal. This is done to prevent users from accessing malware security websites and seeking help. Our website (PCrisk.com) is also on the list. Removing these entries, however, is simple - you can find detailed instructions in this article (note that, although the steps are shown in the Windows 10 environment, the process is virtually identical on all versions of the Microsoft Windows operating system).

1. During your computer start process, press the F8 key on your keyboard multiple times until the Windows Advanced Options menu appears, and then select Safe Mode with Command Prompt from the list and press ENTER.
2. When Command Prompt mode loads, enter the following line: cd restore and press ENTER.
3. Next, type this line: rstrui.exe and press ENTER.
4. In the opened window, click "Next".
5. Select one of the available Restore Points and click "Next" (this will restore your computer system to an earlier time and date, prior to the Luceq ransomware virus infiltrating your PC).
6. In the opened window, click "Yes".
7. After restoring your computer to a previous date, download and scan your PC with recommended malware removal software to eliminate any remaining Luceq ransomware files.
To restore individual files encrypted by this ransomware, try using Windows Previous Versions feature. This method is only effective if the System Restore function was enabled on an infected operating system. Note that some variants of Luceq are known to remove Shadow Volume Copies of the files, so this method may not work on all computers.
To restore a file, right-click over it, go into Properties, and select the Previous Versions tab. If the relevant file has a Restore Point, select it and click the "Restore" button.
If you cannot start your computer in Safe Mode with Networking (or with Command Prompt), boot your computer using a rescue disk. Some variants of ransomware disable Safe Mode making its removal complicated. For this step, you require access to another computer.
To protect your computer from file encryption ransomware such as this, use reputable antivirus and anti-spyware programs. As an extra protection method, you can use programs called HitmanPro.Alert and EasySync CryptoMonitor, which artificially implant group policy objects into the registry to block rogue programs such as Luceq ransomware.
Note that Windows 10 Fall Creators Update includes a "Controlled Folder Access" feature that blocks ransomware attempts to encrypt your files. By default, this feature automatically protects files stored in the Documents, Pictures, Videos, Music, Favorites as well as Desktop folders.
Windows 10 users should install this update to protect their data from ransomware attacks. Here is more information on how to get this update and add an additional protection layer from ransomware infections.
HitmanPro.Alert CryptoGuard - detects encryption of files and neutralises any attempts without need for user-intervention:
Malwarebytes Anti-Ransomware Beta uses advanced proactive technology that monitors ransomware activity and terminates it immediately - before reaching users' files:
- The best way to avoid damage from ransomware infections is to maintain regular up-to-date backups. More information on online backup solutions and data recovery software Here.
