iSeeYou is a security bug affecting iSight cameras in some Apple laptops.[1]


The researchers' decision to study webcam indicator lights resulted from the widely reported WebcamGate case, in which a remote access tool installed on school-issued laptops took photographs of unconsenting students.[2][3]


The security flaw was reported internationally.[4][5][6][7][8][9]

Journalists observed that Apple had sold their laptops as having a "hardware interlock" that was supposed to prevent such an attack,[5][10][11] and called on Apple to implement hardware switches or other strong privacy protections.[11]


The Apple laptops affected are capable of running a variety of operating systems, including macOS, Microsoft Windows, and Linux. Mitigations against iSeeYou may vary by operating system. The researchers released a macOS kernel extension, iSightDefender, to reduce the attack surface under macOS.[1]
