Fake CAPTCHA 🚨: Discover how hackers use your click to infect you 😱

You're probably familiar with those classic CAPTCHA tests that appear on many websites. Yes, the ones where you have to click to confirm you're not a robot, type strange letters and numbers, or select all the traffic lights, buses, and motorcycles. 😅 Although they're usually a nuisance and look like data-harvesting traps, hackers have started using them to trick users into installing malware. ⚠️

At least, that's what security experts are increasingly warning about. Last month, MalwareBytes Labs They detected a fake CAPTCHA that asked you to paste a "verification" text into the Windows command prompt. Additionally, there have been reports of malware called "Quakbot" that uses an even more dangerous variant of this type of CAPTCHA scam.

How do CAPTCHA scams work?

CAPTCHA attacks are risky because users often click on them out of habit when they appear on web pages. Hackers are taking advantage of this instant reaction behavior with fake pop-up messages that closely resemble real CAPTCHA tests. 🚨

In these cases, the user is also asked to click a box to complete a test. However, when you click that box, you end up being redirected to other pages. Other actions ensure that dangerous commands are copied to your clipboard, allowing attackers to execute those dangerous commands on your computer without authorization. 💻

Sometimes, these CAPTCHAs even ask you to press specific key combinations that directly invoke Windows PowerShell or execute certain commands on your device. Therefore, you should be very cautious with any CAPTCHA request that asks you to do something unusual.

These types of attacks are known as ClickFix CAPTCHA attacks because they use social engineering to trick you into clicking on fake CAPTCHAs and other elements, which then trigger malicious responses.

These attacks are surprisingly effective.

To keep you on your toes, each subsequent click in a ClickFix CAPTCHA attack is disguised with additional "verification requests" that hide the malicious nature of what you're doing. In the worst-case scenario, it all ends with you inadvertently executing a malware script that takes control of your PC. 😱

CAPTCHA attacks are reported to have a higher success rate than other scam attempts due to their novel psychological tricks that take advantage of reflexive behavior when our guard is down. The only real protection is to stay alert, especially when visiting unfamiliar websites. And, of course, have a Reliable antivirus software that protects you from threats. 🛡️

In conclusion, fake CAPTCHAs are an increasingly sophisticated threat 🕵️‍♂️ that take advantage of our trust and habit of quickly interacting with these tests to infect our computers with dangerous malware 💻⚠️. The key to not falling for these scams is to remain cautious, distrust any strange requests linked to CAPTCHAs 🚫 and avoid actions such as copying and pasting commands or executing key combinations without being 100% sure of their origin 🔒.

Plus, having a good, up-to-date antivirus is essential to strengthen our protection against these and other digital threats 🛡️💡. Don't let a simple click put your security at risk! 🔐✨
