Chinese Mobile Phone Cameras Are Not-So-Secretly Recording Users' Activities (globalvoices.org) 91

Posted by msmash from the closer-look dept.
Oiwan Lam, reporting for Global Voices: It has been widely reported that software and web applications made in China are often built with a "backdoor" feature, 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 device's camera would self-activate. [...] 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.

[...] After the news of the self-activated camera bug spread, users started testing the issue on other applications and found that Baidu's voice input application has access to both the camera and voice recording function, which can be launched without users' authorization. A Vivo NEX user found that once she had installed Baidu's voice input system, it would activate the phone's camera and sound recording function whenever the user opened any application -- including chat apps, browsers -- that allows the user to input text.

      If China were the only one moving that way, it would possibly limit their economic growth. The problem is the entire WORLD seems to be moving that way, some at a faster rate than others. But it's not like I can honestly look at my United States and say we aren't doing the exact same thing, and whenever one of us plebes mention it in a public forum all that has to happen is somebody whines about how it's for our own protection and then it ceases to be an issue of importance.

      While the level of scrutiny and inspection procedures performed by Apple before publishing an iOS application is on a completely different level than that of Google and their Play Store, it's technically possible. But the case with these Chinese Android phones isn't really about this or that rogue app possibly showing up on the Play Store, but rather that they all come with a customized Android build prepared from start with a selection of malware/spyware. It's a complete ready-to-go, ready-to-spy package.

      Both iOS and Android already give the device owner control over what functions an app is able to access. For example, Android notified me that an update to one of the games on my tablet was asking for access to the microphone and camera. I of course denied those permissions (the game seems to run just fine without them). Since my tablet is rooted, I also get control over which apps are allowed to use the network. So even with the few programs which need such access (like a photo-to-PDF converter), I'm confident it isn't transmitting info about me back to the app maker.

      There are two reasons for the problem.
      • Certain apps need such permissions. The voice input app mentioned in the summary requires access to the microphone to function. The maker of the app can then abuse that permission to use the microphone to record conversations and transmit them back to the mothership. This is even more insidious with voice recognition apps, which have to record conversations and transmit them back for the recognition stage anyway. At that point the difference between legitimate and illegitimate use becomes whether the company keeps the recordings on file, or deletes them after the recognition is completed (which is why I've long advocated that voice recognition be moved to the device itself now that processors are getting to the point where that's feasible). It's impossible for OS-level restrictions to prevent this type of abuse.
      • China has encouraged forking Android and developing its own version for use in the Chinese market. Ostensibly this is to reduce the amount of control foreign companies (namely Google) have over products used within China. Most people however suspect that it's done so the Chinese government can insert its own monitoring software directly within the OS itself. The kind of stuff the NSA only dreams it could do. The maker of an open-source OS has no control over what happens to forks.

    ...with practically any cheap Chinese crapdroid phone/tablet, as well as Android TV boxes, aimed at the western markets - pretty much all of them run customized (often half-assed) Android builds bundled with various sets of malware/spyware. This even goes for the somewhat larger brands that have an office presence on the European continent trying to profile themselves in the west with TV/magazine/sports advertisements, like f.e. Doogee and Oukitel.

    Over the past 5-6 years I've purchased close to two dozen Chines phones/tablets (as development toys) in both the low and mid price tiers, and I've yet to find a single one that actually comes with a clean and honest Android build. Spending time on the various Android phone/tablet hacking forums on the Internet you'll find droves of new reports about this every month, and all popular Chinese brands are mentioned.

    Baidu's voice input system... would activate... whenever the user opened any application... that allows the user to input text

    So, looking at the technical underpinning, it functions like the native keyboard app, which loads on demand for applications which support its input.

    I can't reach the article, so here is the real question: Is there evidence of nefarious activity, particularly the suspicious caching or transmission of data?

    Because a camera/mic activating on its own isn't necessarily doing much of anything. It certainly merits investigation, but the headline is not justified by the content of the summary.

    After all, if it's "not-so-secretly" doing bad things, there should be plentiful, clear evidence of bad things happening. If there are hours of audio/video being recorded or transmitted by some phone, why not mention that?

    • Well, that's better worded than what I was probably going to say, so thank you.

      It does seem like it's just the voice input kicking in when you're likely to want it, not a nefarious plot. Besides, the Party probably has better bits of spyware on there already.

The only arguably legitimate reason that I can think of would be if the Android web client API has some kind of anti-malicious-website functionality built-in, for which Google automatically checks for hostile or compromised websites.
