A critical macOS vulnerability allowing remote attackers to gain complete system control without passwords is actively being exploited in the wild. The bug affects the built-in screen-sharing functionality across multiple Mac systems.

Security researchers have confirmed that hackers are actively exploiting a screen-sharing vulnerability to gain unauthorized access to Mac computers. The flaw enables attackers to log in remotely without requiring user credentials or authentication. The vulnerability affects macOS screen-sharing features, which are commonly enabled by default or used for legitimate remote support purposes. Once exploited, attackers obtain full system control, allowing them to access files, install malware, and conduct further attacks. Apple has not yet issued a public patch for the vulnerability. Security experts recommend immediately disabling screen-sharing functionality if not actively needed. Users should also ensure their systems are fully updated and consider using additional authentication methods for remote access. The active exploitation indicates the flaw is being weaponized in real-world attacks. Mac users should treat this as a high-priority security concern until an official fix is released.
