According to reports, a loophole with the Google Camera app on Pixel smartphones and Samsung camera app left them vulnerable to attack from hackers. Researchers at security firm Checkmarx said hackers could gain remote access to devices using the apps through a malicious app, and potentially take photos, record videos and audio as well. The app would require access to storage, a commonly granted permission on Android, and could then exploit the Camera app, gaining access to private user data. If users had geo-tagging for photographs turned on, GPS data could be viewed by the attackers as well. The spying app also had the ability to record two-way phone calls, and use the phone's proximity sensor to detect whether it was face down or being used on a phone call. Google has said it had fixed the loophole in a patch issued in July, while Samsung has said it was made aware of the trouble through Google and has since released patches for all Samsung devices that may have been affected. Checkmarx has said that other makers of Android phones may be at risk too, but any information to that effect is yet to come to light.
