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!
