Adult webcam for free hack
Brocker and Checkoway focused their testing on older machines, like the i Mac G5 and Intel-based i Macs, Mac Books, and Mac Book Pros from 2008 and earlier, so it's unclear if newer machines are also vulnerable.
The duo were inspired to tackle this topic after a webcam controversy within Pennsylvania's Lower Merion School District.
"At the same time, researchers have demonstrated attacks exploiting the presence of sensors." Checkoway and Brocker offers some suggestions for how Apple can defend its i Sight camera against attacks, but there is no word what Cupertino will do to patch the problem.
About 2,300 students at Harriton High School were given Mac laptops, but unbeknownst to those students and their parents, the laptops were equipped with tracking software that could remotely activate the computer's webcam to take photos of the user, as well as capture screen shots.It was intended as a means to locate lost or stolen laptops, but was apparently activated in more questionable circumstances as well."Our results in this paper demonstrate that, at least in some cases, people have been correct to worry about malware covertly capturing images and video," Checkoway and Brocker wrote."We show a vulnerability in the i Sight webcam that affects a particular range of Apple computers that can be exploited to turn on the camera and capture images and video without the indicator illuminating." By doing so, the team was able to capture video and photos unbeknownst to the person in front of the computer's camera.The researchers informed Apple about the LED disabling vulnerability in July 2013 and the virtual machine escape in August.
"Apple employees followed up several times but did not inform us of any possible mitigation plans.
