Interlock attackers are targeting IT professionals with fake CAPTCHA pages and a technique known as ClickFix, which tricks victims into executing malicious commands on their own computers.
How the Attack Works
- Fake website: Victims visit fraudulent websites impersonating legitimate IT tools, such as network scanners.
- Fake CAPTCHA: A counterfeit verification page instructs users to complete additional steps.
- Malicious command: Victims are tricked into copying and executing commands through Windows Run or PowerShell.
- Malware infection: The commands can download malware, steal credentials, and give attackers further access to compromised systems.
How to Stay Protected
- Download software only from verified official websites.
- Never execute commands supplied by an unexpected CAPTCHA or webpage.
- Use endpoint protection and monitor suspicious PowerShell activity.
- Protect administrator accounts with multifactor authentication.
- Train employees to recognize fake verification pages.
Already executed a suspicious command? Disconnect the affected device from the network and contact your IT security team immediately.
Final Thoughts
ClickFix attacks exploit trust and familiarity rather than relying entirely on software vulnerabilities. Even experienced IT professionals must verify unexpected instructions before executing commands.
