How to remove the ViperSoftX Remote Access Trojan (RAT)

What is the ViperSoftX RAT?

ViperSoftX is a JavaScript-based Remote Access Trojan (RAT). Malware of this type allows stealthy remote access and control over an infected machine. These Trojans can have a wide variety of dangerous functionality, which enables likewise varied misuse of the compromised device.

The primary purpose of ViperSoftX is stealing cryptocurrency transactions, however, it has other features as well. ViperSoftX RAT infections pose a significant threat to computer and user safety.

ViperSoftX malware overview

The ViperSoftX RAT uses strong obfuscation methods, which complicate its detection and analysis. Amongst these techniques is disguising its malicious code under seemingly legitimate names and parts of encrypted code (AES cryptographic algorithm).

As this malware is in the process of ensuring persistence, it gathers the following machine information: device serial number and name, username, operating system architecture, and installed anti-virus programs.

The purpose of ViperSoftX is redirecting Bitcoin and/or Ethereum cryptocurrency transactions to the cryptowallets owned by cyber criminals behind the infection. This Trojan does so by replacing cryptocurrency wallet addresses with its own in clipboard data (i.e. short-term storage buffer for copied content).

Additionally, the ViperSoftX malware targets the log-in credentials of cryptocurrency wallets and the funds stored therein (full wallet list).

Note that this malware is capable of infiltrating and executing files. Therefore, this RAT might be used to download/install ransomware, cryptominers, and other malicious programs.

To summarize, ViperSoftX infections can lead to data loss, device damage, serious privacy issues, financial loss and identity theft. If it is suspected/known that the ViperSoftX RAT (or other malware) has already infected the system, use anti-virus software to remove it immediately.

Remote access trojan examples

JSSLOADER, VoidRAT, CRAT, PyXie, and Quaverse are some examples of other remote access Trojans. These malicious programs can have a wide variety of dangerous functionality and these functions can be in different combinations.

Common malicious capabilities include: data extraction and exfiltration from compromised devices and installed applications (e.g. browsers), keylogging (key stroke recording), data encryption and/or screen locking for ransom purposes, download/installation of additional malware, audio and video recording/live-streaming via microphones and webcams, use of system resource for cryptocurrency mining, and so on.

Regardless of how malicious programs operate, their purpose is to generate revenue for the cyber criminals using them. To protect device and user safety, all malware infections must be eliminated immediately upon detection.

How did ViperSoftX infiltrate my computer?

Malware (including ransomware) is usually distributed via malspam campaigns, unofficial software activation ('cracking') tools, Trojans, dubious file/software download sources, and fake software updating tools.

When cyber criminals attempt to distribute malware via malspam campaigns, they send emails that contain malicious attachments or download links for malicious files. Typically, they disguise their emails as official and important. If recipients open the attached file (or a file downloaded via a website link), they cause installation of malicious software.

Cyber criminals commonly attach executable files (.exe), archive files such as RAR, ZIP, PDF documents, JavaScript files and Microsoft Office documents to their emails. Software 'cracking' tools supposedly activate licensed software illegally (bypass activation), however, they often install malicious programs and do not activate any legitimate installed software.

Trojans are other rogue programs that can cause chain infections. I.e., when a Trojan is installed on the operating system, it can install additional malware.

Free file hosting websites, freeware download websites, Peer-to-Peer networks (e.g., torrent clients, eMule), unofficial websites, and third party downloaders are examples of other sources that are used to distribute malware. Cyber criminals disguise malicious files as legitimate and regular. When users download and open them, they inadvertently infect their computers with malware.

Fake software updating tools install malicious software rather than updates/fixes for installed programs, or they exploit bugs/flaws of outdated software that is installed on the operating system.

How to avoid installation of malware

To avoid infecting the system with malware spread through spam mail, you are strongly advised not to open suspicious or irrelevant emails, especially those with any attachments or links present in them. Use official and verified download channels.

Additionally, all programs must be activated and updated with tools/functions provided by legitimate developers, since illegal activation tools ("cracks") and third party updaters commonly proliferate malicious software.

To ensure device integrity and user safety, it is paramount to have reputable anti-virus/anti-spyware software installed and kept updated. Furthermore, use these programs to run regular system scans and to remove detected/potential threats.

Do not trust irrelevant emails that contain attachments or website links, especially if received from unknown, suspicious addresses.

Fake update tools infect systems by installing malicious programs rather than updates/fixes for installed software, or by exploiting bugs/flaws of outdated software that is installed on the computer.

Further encryption of any unaffected files can be prevented by uninstalling the ransomware, however, already compromised files remain encrypted even after removal of the rogue software and can only be recovered from a backup.

If you believe that your computer is already infected, we recommend running a scan with Combo Cleaner Antivirus for Windows to automatically eliminate infiltrated malware.

Update November 22, 2022 - The developers of ViperSoftX continue to improve upon this malware; these developments include upgraded and additional anti-detection capabilities.

ViperSoftX has been observed infecting Chromium-based browsers with a malicious browser extension dubbed "VenomSoftX". This piece of software infiltrates systems under the guise of legitimate and popular extensions (e.g., Google Sheets, etc.).

The VenomSoftX extension has a broad list of abilities: giving the cyber criminals full access to visited websites, doctoring cryptocurrency addresses and other data (including log-in credentials) on crypto exchange websites (e.g., Binance, Blockchain.com, Coinbase, Gate.io, and Kucoin), and well as operating as a clipper. More information on these developments can be found in an article by Jan Rubín on the decoded.avast.io website.

Update May 5, 2023 - New variants of ViperSoftX have been detected. These iterations include improved anti-detection, an expanded list of targeted cryptocurrency wallets, and data extraction abilities from non-Chromium browsers (e.g., Mozilla Firefox). Furthermore, these ViperSoftX versions seek out files associated with password managers, namely 1Password and KeePass.

Update July 12, 2024 - The current variant of ViperSoftX stands out for using the Common Language Runtime (CLR) to dynamically load and execute PowerShell commands within AutoIt, enabling smooth PowerShell functionality while evading detection.

Recent ViperSoftX attacks begin when users download an ebook from a malicious torrent link. The downloaded RAR file contains hidden threats, including a deceptive shortcut file posing as a PDF, PowerShell script, AutoIt.exe, and AutoIt script disguised as JPG files. A hidden folder mirrors the contents of the current folder, except for a PDF or ebook document, which serves as a decoy.

Update April 16, 2025 – ViperSoftX has been observed featuring in a new campaign that began on April 1. This activity sought to infect the devices of Korean users. These infections involved other malware, including malicious PowerShell scripts, a VBS downloader, PureCrypter malware, and the Quasar RAT.

Based on the comments in the C&C (Command and Control) server communication, it is likely that the threat actors behind this campaign speak Arabic. More information on this campaign can be found in an article on the AhnLab SEcurity intelligence Center (ASEC) website.
