.luces Files Virus – Distribution

The distribution of .luces files virus is likely to happen with the help of commonly used techniques such as malspam, corrupted freeware installers, software cracks, infected web pages, fake software update notifications and other.

It is believed that the most preferred method of distribution is malspam. Since it is a well-known fact that almost every online user has an email address where he receives a large number of emails on a daily basis, hackers often attempt to deliver their ransomware by the use of spam email campaigns.

The ransomware payload is usually disguised as an important document, shopping offer, or payment notification. The corrupted file is often attached to emails that pose as representatives of popular businesses, frequently used services, and governmental institutions. As you might guess by loading such a file on your device you automatically infect it with the malicious code embedded in the code of this file.

Another way for hackers to disguise their ransomware activator is by injecting it into the code of any web page and set this page to trigger an automatic download whenever loaded in a web browser. URLs to infected pages could be again presented in emails that attempt to deliver the malicious code on your device, tied to online advertisements, shared in forum communities or displayed on social media channels.

.luces Files Virus (STOP Ransomware) – Overview

Analyses of this STOP ransomware strain reveal that the malicious executable files Padonok.exe and load1903.exe have been utilized in recent attack campaigns. Once one of these files is started on a target machine, it becomes able to disrupt system security by altering some of its essential settings.

Along with this payload file, .luces ransomware establishes a few more malicious files that support the attack. For the purpose, the threat could be either set to connect a remote server and download them or create them directly on the system. As their locations, .luces files virus may choose some of the following folders:

  • %AppData%
  • %Local%
  • %LocalLow%
  • %Roaming%
  • %Temp%

When all needed files are established on the device the ransomware starts executing them in a predefined order which enables it to pass through several attack stages. During the attack, it could automatically obtain administrative rights and this way gains the permission to misuse system resources for malicious purposes.

Affected could be the Windows Registry as well. Since it stores important low-level system settings and apps’ permissions, crooks often configure their ransomware viruses to access this database. So in order to misuse some registry functionalities, .luces STOP ransomware could add malicious values under certain registry sub-keys. It is very likely that it will attempt to exploit RUN and RUNONCE keys as they could help it to automatically load malicious files on each system start.

Furthermore, by corrupting the RUNONCE registry key, .luces ransomware could accomplish the final attack stage. For it the threat needs to load a previously dropped ransom note file on the screen. Similar to its predecessors (.promorad2, .pulsar1, .promorad, etc.) .luces could present the following message:

This message aims to blackmail you into transferring hackers a ransom fee in exchange for a data decryption tool. Even though, the message does not specify the amount of the ransom, it is likely to vary from $50 to a few hundred dollars.

Beware that a successful ransom payment does not guarantee the recovery of .luces files. On one hand, hackers could send you a broken decryptor. On the other hand, they could skip answering you at all.

.luces Files Virus – Encryption Process

The main goal of .luces files virus is to encrypt files stored on your infected machine. To make you more prone to pay a ransom fee, the ransomware targets only files that are used very often. Such files are:
