A cybersecurity researcher has introduced FileFix, a new variant of the ClickFix social engineering attack, which exploits the Windows File Explorer address bar to execute malicious PowerShell commands. This method tricks users into pasting commands by disguising them within what appears to be a legitimate file-sharing notification, making it a more user-friendly approach for attackers. FileFix highlights the adaptability of phishing techniques, as it presents a familiar interface to users while executing harmful commands.

iClicker's website was compromised in a ClickFix attack that used a fake CAPTCHA to trick users into executing a PowerShell script that potentially installed malware on their devices. The attack, targeting college students and instructors, aimed to steal sensitive data, but the malware's specific nature varied based on the visitor type. Users who interacted with the fake CAPTCHA between April 12 and April 16, 2025, are advised to change their passwords and run security checks on their devices.
