Prove you’re human by reading up on the latest Captcha scam

Imagine you’re browsing the internet, and suddenly, the typical pop-up appears asking you to confirm that you’re not a robot. Since you’ve gone through this process countless times, you likely click to continue almost automatically and without much thought. But what if we told you that this simple action could compromise the security of your entire device?

Cybercriminals have found a new way to deceive users through “FakeCaptcha,” a tactic designed to infect devices with malware without the user realizing it, by mimicking the appearance of legitimate CAPTCHAs. According to Gen Digital’s Threat Report for the third quarter of 2024, this type of attack has seen an alarming 614% increase worldwide, with notable cases in countries such as Spain, Italy, and Argentina.

While FakeCaptcha poses a serious threat to all users—including even the most tech-savvy—fortunately, you have access to Avast Free Antivirus, a versatile security tool that helps defend your devices against this and many other cyber threats. Want to learn more about FakeCaptcha and how to protect yourself? We’ll cover everything you need to know below.

What Sets FakeCaptcha Apart from Other Similar Scams?

Exploiting Familiarity

At first glance, FakeCaptcha is another scam in the vast world of cyber threats. However, its cleverness lies in exploiting an action we perform almost automatically—verifying that we are not robots.

Unlike other scams that trick users into providing personal information or directly downloading malicious files, FakeCaptcha uses our familiarity with CAPTCHA verification to subtly introduce malware into our devices.

Social Engineering Techniques

To make matters worse, cybercriminals use social engineering techniques to get victims to execute malicious code on their devices by following instructions that seem to be part of the verification process. This dangerous and highly effective combination of familiarity and deception makes FakeCaptcha especially relevant today.

How Does the FakeCaptcha Scam Work?

The process behind this new scam is surprisingly simple, which contributes to its effectiveness:

Accessing a Compromised Page

While browsing the internet, you may come across a website that has been compromised or specifically designed for this purpose. When you try to access its content, you are presented with a fake CAPTCHA that looks almost identical to a real one.

Interacting with the CAPTCHA

When you click on “I’m not a robot,” a malicious script is silently copied to your clipboard without your knowledge.

Executing the Script

You are then instructed to paste and execute the clipboard content in your device’s command console under the pretext of completing the verification process.

Device Infection

By following these instructions, the script acts as a “dropper,” downloading and installing malware on your system.

The most common malware associated with this technique is Lumma Stealer, a sophisticated information-stealing program capable of extracting passwords, financial data, and all types of personal information.

How Can We Protect Ourselves from This Threat?

The good news is that by taking extra precautions and using the right tools, we can effectively protect ourselves against FakeCaptcha and similar scams. Here are some recommendations:

Be Wary of Unusual Requests

If a CAPTCHA appears on a website that normally doesn’t require one or asks you to perform actions outside the webpage or on your device, the best course of action is to be skeptical and avoid clicking anything. Legitimate CAPTCHAs will never ask you to copy and paste text or perform unusual actions.

Stay Informed and Alert

Understanding the tactics used by cybercriminals will help you recognize the warning signs and avoid falling into their traps.

Verify the Website’s URL

Before interacting with a CAPTCHA, ensure that the website address is legitimate and correctly spelled. Attackers often create fake websites with URLs similar to real ones, using tricks like replacing a zero (0) with an uppercase “O” or a lowercase “L” with an uppercase “I.”

Avoid Downloading Files from Untrusted Sources

While FakeCaptcha doesn’t always involve direct downloads, it’s essential to remember never to download files or programs from suspicious or unverified websites.

Enable Two-Factor Authentication (2FA)

Whenever possible, enable two-factor authentication for your online accounts, especially email and banking services. This adds an extra layer of security in case cybercriminals access your credentials.

Keep Your Security Software Updated

Ensuring that your security program is always up to date is crucial for detecting and blocking malicious scripts before they cause harm. Our recommendation? Avast Free Antivirus.
