Is Your Phone Spying on You? Inside Chinese Camera Backdoors
It has been widely reported that software and web applications made in China are often built with a backdoorfeature, allowing the manufacturer or the government to monitor and collect data from the user's device.
But how exactly does the backdoor feature work? Recent discussion among mobile phone users in mainland China has shed some light on the question.Last month, users of Vivo NEX, a Chinese Android phone, found that when they opened certain applications on the phone, including Chinese internet giant QQ browser and travel booking app Ctrip, the mobile devices camera would self-activate.
Different from most mobile phones, where a camera can be activated without giving the user any signal, the Vivo NEX has a tiny retractable camera that physically pops out from the top of the device when it is turned on.
Though perhaps unintentionally, this design feature has given Chinese mobile users a tangible sense of exactly when and how they are being monitored.
One Weibo user observed that the retractable camera self-activates whenever he opens a new chat on Telegram, a messaging application designed for secured and encrypted communication.
While Telegram reacted quickly to reports of the issue and fixed the camera bug, Chinese internet giant Tencent instead defended the feature, arguing that its QQ browser needs the camera activated to prepare for scanning QR codes and insisted that the camera would not take photos or audio recordings unless the user told it to do so.After the news of the self-activated camera bug spread, users started testing the issue on other applications and found that Baidus voice input application has access to both the camera and voice recording function, which can be launched without usersauthorization.
A Vivo NEX user found that once she had installed Baidu's voice input system, it would activate the phones camera and sound recording function whenever the user opened any application including chat apps, browsers that allows the user to input text.Baidu says that the self-activated recording is not a backdoor but a frontdoorapplication that allows the company collect and adjust to background noise so as to prepare for and optimize its voice input function. This was not reassuring for users any microphone collecting background noise would also unquestionably capture the voices and conversations of a user and whomever she speaks with face-to-face.https://www.ttspy.com/how-does-ttspy-live-spy-phone-camera-app-work.html
