Ambient light sensors, while designed to improve power consumption and reduce eye strain by adjusting screen brightness, could also pose a privacy threat. Research from Massachusetts Institute of Technology has indicated that under specific conditions, these sensors could allow external parties to monitor user actions, presumed to be private, such as specific screen gestures. Although various limitations make immediate threats unlikely, the researchers emphasize the importance of public awareness regarding potential future threats.

DDoS attackers are pouncing on unpatched vulnerabilities
Why seek new attack methods when you can leverage existing, publicly known vulnerabilities? Exploiting these older weaknesses can be more effective, as they are often
