Security researchers have identified AmnesiaStealer, a new information-stealing malware targeting macOS users through ClickFix attacks. The threat includes a streaming module enabling attackers to remotely control victims' web browsers.

AmnesiaStealer represents a notable escalation in macOS threats, combining data theft with interactive browser hijacking capabilities. The malware uses ClickFix attacks—a social engineering technique exploiting fake error messages—to distribute the payload to unsuspecting users. Once installed, the malware can extract sensitive information from compromised systems. More critically, its streaming module grants attackers real-time control over browser sessions, potentially enabling credential theft, unauthorized transactions, or further system compromise. The ability to interactively control browsers significantly increases the attack's scope beyond traditional information stealing. Attackers can monitor user activity, intercept sensitive sessions, or manipulate web interactions in real-time. MacOS users should remain cautious of unsolicited error messages directing them to download security tools or updates. Security software vendors recommend verifying system alerts through official channels and maintaining current security patches.
