.horon Files Virus – How Does It Infect and What Does It Do?

The ransomware infection called .horon files virus is designed to infect computer systems in order to interfere with their settings and become able to encode valuable personal files. As identified by security researchers it is a strain of the infamous

STOP ransomware.

Currently, .horon STOP ransomware is lurking around the web. The attack campaigns that are spreading .horon virus samples may be realized with the help of several common techniques such as malspam, malvertising, freeware bundles, and websites corruption.

Malspam or spam emails that are trying to deliver malicious code on computer machines is the most preferred spread technique. Hackers often bet on it as it enables them to reach a vast number of online users around the globe. Several traits could help you recognize the emails that are part of malspam campaigns. The most distinctive ones are URLs presented as buttons, direct links, in-text links, images, etc. and file attachments presented as invoices, order IDs, purchase details, coupons, special offers, and even legal papers. In order to make you more prone to interact with these elements and hence run the ransomware on your PC, hackers set the emails to pose as representatives of well-known brands, services, financial and governmental institutions.

So beware and whenever you spot the above-mentioned elements to be present in a received email make sure to check their security level. One of the most reliable ways to do this is by uploading them for a security check on the VirusTotal website. Another one suitable for archived files is the free online archive extractor and virus/malware scanner ZipeZip.

What happens when .horon files virus loads on your device? It initiates a long sequence of malicious operations that disrupt system security and enable it to reach the main infection stage – data encryption.

For the data encryption process, .horon ransomware activates a specific cipher module that scans all system drives for target types of files and encodes the matches with the help of a sophisticated cipher algorithm. Unfortunately, it is likely that all common files listed below are among the targets of this nasty ransomware:

  • Audio files
  • Video files
  • Document files
  • Image files
  • Backup files
  • Banking credentials, etc

Following encryption, the ransomware leaves all encrypted files inaccessible and renamed with the extension .horon . As a result, you are forced to pay a ransom fee in cryptocurrency to cyber criminals. This happens via a ransom note message that could be placed on the desktop and in every folder that contains encrypted files.

According to the details presented in this message, when you pay the ransom you will receive a decryption tool for .horon files. However, since there is no guarantee that this tool is a functional one, we recommend you to avoid any negotiations with cyber criminals and attempt to deal with the problem in a secure way. Furthermore, there is a chance that the available free decryption tool created by the security researcher Michael Gillespie will be soon updated to support .horon files decryption. As soon as this happens we will update this article with information about the decryptor.
