And because nan malware stays dormant until a existent personification engages, astir accepted information devices don’t emblem it. To them, it looks for illustration personification conscionable followed a normal prompt.

A Real-World Malware Case Triggered by ClickFix

Let’s return a look astatine really ClickFix behaves successful a real-world script erstwhile analyzed successful an interactive sandbox environment.

Fake CAPTCHA detected by ANY.RUN sandbox

In this ANY.RUN study session, nan malware disguises itself down a clone CAPTCHA page. At first glance, it looks for illustration a harmless verification step, thing users spot each nan time. But erstwhile nan personification starts interacting, nan trap is set.

The page instructs nan personification to:

1. Press Windows + R
2. Paste nan bid from nan clipboard (which was automatically copied erstwhile they checked nan clone CAPTCHA) into nan Run dialogue
3. Hit Enter

Verification steps that request to beryllium completed to execute malicious payload

What seems for illustration a normal process really triggers a hidden PowerShell script. If nan personification follows these steps, nan malware is softly executed successful nan background, giving nan attacker entree to nan strategy aliases downloading further payloads.

The process of moving PowerShell bid revealed wrong ANY.RUN sandbox

This behaviour was afloat revealed wrong ANY.RUN’s interactive sandbox, wherever analysts could replicate nan nonstop steps a personification mightiness take. As nan sandbox allowed afloat interaction, nan clone CAPTCHA page responded and moved nan infection process forward, exposing nan malware’s logic and payload.

• Fake information warnings – Popups pretending to beryllium from Windows aliases antivirus package show users to property Windows + R and tally a bid to “fix” an issue. The bid is malicious.

• Fake package activation pages – Attackers connection a clone proceedings aliases activation step, asking users to transcript a book into nan terminal aliases Run dialogue, unknowingly executing malware.

Don’t Let Clicks Turn into Compromises

ClickFix shows conscionable really acold attackers will spell to enactment hidden, utilizing mundane interactions to present vulnerable payloads.

To protect against threats for illustration this, businesses request much than surface-level detection. They request nan expertise to interact, observe, and understand really malware behaves successful existent scenarios. That’s precisely what an interactive sandbox provides.
