A new information-stealing malware called ClickLock targets macOS systems by terminating all visible processes to trick users into entering their login credentials. The attack forces users into a compromised authentication state.

ClickLock operates by systematically closing running applications, leaving users with only the system login prompt visible. This social engineering approach pressures victims into believing they must authenticate to regain access to their devices. Once users enter their login password, the malware captures the credentials for later exploitation. This technique bypasses traditional security measures that typically require malware to run with elevated privileges to access password information. The malware targets macOS specifically, taking advantage of the platform's process management system. Security researchers recommend users verify system legitimacy before entering credentials and remain cautious of unexpected authentication requests. MacOS users should keep systems updated with the latest security patches and use reputable antivirus software to detect suspicious process termination patterns. Apple has not yet released specific guidance addressing this particular threat variant.
