RandomLocker Ransomware – Distribution Tactics
RandomLocker ransomware infection is triggered by an executable file called Ransomware.exe as releveled by the analysis of its sample. Hackers could use several common methods for the distribution of this executable file. The main one is believed to be email spam campaigns. This method is preferred by bad actors as it allows them to craft email messages in a way that they seem legit and important. Such emails may impersonate representatives of well-known companies or even governmental institutions. Their text messages usually provide some kind of important information and insist that you need to download and open an attached file as soon as possible. Malicious attachments may be present as documents, invoices, tax payments, delivery receipts, reports and other. All they contain the infection code of RandomLocker. And in case that you download and open such a corrupted file it infects your PC with the ransomware.
For the sake of your security, you could use a free online file extractor each time before you open new file on your PC. Tools of this kind scan the code of each uploaded file for specific malicious traits. After, the scan you could see whether the uploaded file contains malicious elements or not. The information could help you to prevent corrupted files from infecting your PC.
RandomLocker – Analysis of the Infection
The infection begins once RandomLocker’s payload is running on the system. The payload may be designed to initiate the creation of additional malicious files that support the infection process. Malicious files usually are able to modify some essential system settings in order to plague it and achieve persistence. As most data locker ransomware RandomLocker is likely to access the Registry Editor and some malicious values that ensure its automatic execution on each Windows system start.
The Registry Editor is a database that stores all low-level settings for the operating system and the installed applications. RandomLocker’s values could be added under the registry sub-keys Run and RunOnce as they are able to run the processes which are listed there.
Additionally, RandomLocker crypto virus may be also set to scan the system for particular details and then sends them to its command and control server. It is possible after the ransomware establishes a connection with its server. If you want to prevent the collection of your sensitive data as well as the installation of additional malware on your PC, you should remove all ransomware files and objects from the infected device as soon as possible.
RandomLocker Ransomware – Data Encryption Process
RandomLocker ransomware is known to use AES algorithm for file encryption. With the help of this cipher the treat is able to modify the original code of target files and render them completely out of order so you can no longer access the information they store. Each corrupted file can be recognized by the extension .rand that is appears at the end of its name.
Threats of this kind are usually set to scan predefined folders to locate all target files. Eventually you may see all types of files listed below to be encrypted by RandomLocker ransomware:
- Archives
- Backups
- Images
- Videos
- Music
- Documents
At the end of the attack when your system is plagued and your files are corrupted, the crypto virus displays its ransom note on the PC screen. All that the note informs is:
→Ooops, your files have been encrypted!
Encryption was produced using unique key generated for this computer.
To decrypt files, you need to otbtain private key.
The single copy of the private key, with will allow you to decrypt the files, is located on a secret server on the internet;
The server will destroy the key within 24 hours after encryption completed.
Payment have to be made withinn 24 hours
To retrieve the private key, you need to pay 10$ in BTC
Bitcoins have to be sent to this address: 3GPg3tgwZakR5uTELzjMJRj1NarxHH9YdJ
After you’ve sent the payment send us an email to randomlocker@tuta.io with subject: UNLOCK ***

Step 2: Uninstall RandomLocker and related malware from Windows
Here is a method in few easy steps that should be able to uninstall most programs. No matter if you are using Windows 10, 8, 7, Vista or XP, those steps will get the job done. Dragging the program or its folder to the recycle bin can be a very bad decision. If you do that, bits and pieces of the program are left behind, and that can lead to unstable work of your PC, errors with the file type associations and other unpleasant activities. The proper way to get a program off your computer is to Uninstall it. To do that:
Follow the instructions above and you will successfully delete most unwanted and malicious programs.
Step 3: Clean any registries, created by RandomLocker on your computer.
The usually targeted registries of Windows machines are the following:
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Run
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Run
- HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\RunOnce
- HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\RunOnce
You can access them by opening the Windows registry editor and deleting any values, created by RandomLocker there. This can happen by following the steps underneath:
Tip: To find a virus-created value, you can right-click on it and click "Modify" to see which file it is set to run. If this is the virus file location, remove the value.
Before starting "Step 4", please boot back into Normal mode, in case you are currently in Safe Mode.
This will enable you to install and use SpyHunter 5 successfully.
Step 4: Boot Your PC In Safe Mode to isolate and remove RandomLocker
Step 5: Try to Restore Files Encrypted by RandomLocker.
Method 1: Use STOP Decrypter by Emsisoft.
Not all variants of this ransomware can be decrypted for free, but we have added the decryptor used by researchers that is often updated with the variants which become eventually decrypted. You can try and decrypt your files using the instructions below, but if they do not work, then unfortunately your variant of the ransomware virus is not decryptable.
Follow the instructions below to use the Emsisoft decrypter and decrypt your files for free. You can download the Emsisoft decryption tool linked here and then follow the steps provided below:
1 Right-click on the decrypter and click on Run as Administrator as shown below:
2. Agree with the license terms:
3. Click on "Add Folder" and then add the folders where you want files decrypted as shown underneath:
4. Click on "Decrypt" and wait for your files to be decoded.
Note: Credit for the decryptor goes to Emsisoft researchers who have made the breakthrough with this virus.
Method 2: Use data recovery software
Ransomware infections and RandomLocker aim to encrypt your files using an encryption algorithm which may be very difficult to decrypt. This is why we have suggested a data recovery method that may help you go around direct decryption and try to restore your files. Bear in mind that this method may not be 100% effective but may also help you a little or a lot in different situations.
Simply click on the link and on the website menus on the top, choose Data Recovery - Data Recovery Wizard for Windows or Mac (depending on your OS), and then download and run the tool.
