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.
