A design flaw in the Chrome browser allows malicious websites to use your computer's microphone to eavesdrop on you, one developer has claimed, although Google denies this is the case.

    the language that mandates that behavior was removed from the spec in a later errata

    I'm usually all for being suspicious of Google, but I'd much rather focus a bit more on the W3C : the original mandated feature was addressing a clear privacy issue and yet it was just removed. Is the W3C's reasoning documented anywhere?

      Re: Dodgy?

      I'm guessing this was changed to allow the use case of; people continuing to use mic input (having a conversation, etc.) while browsing other web pages. Like how you can talk to someone on Skype without having to have the Skype window visible and in-focus all the time.

      Perhaps browsers should prevent cam/mic input starting on non-focussed pages and, once active, ask the user if they want to continue sending if the input-receiving page is de-focused.

        I think you're right about the case for continuing use of the mic, hence the original wording could be considered to be too prescriptive.

        Your suggested solution seems a good one, so I'm puzzled that the W3C chose to pull the whole issue, rather than suggest something on those lines.

        You propose a good solution, but perhaps it may be simler to make it inescapably, blindly obvious, even to a user, that *a* tab is using the mic. In most cases people will only be expecting to use the mic on one tab, so when the title bar stays red (or whatever the signal is), they should take that as a prompt to check for other windows.

        Re: Dodgy? I have an idea...

        If you can afford to (and are willing to help the sagging, flagging, lagging hardware industry sales), buy a second, dedicated conferencing device. Why should we allow unmonitored access to the internal private contents of our devices?

        Even if it is a valid reason to keep the mic running while the user flips through tabs looking for content, the user should NEVER be deprived of knowing factually the status of the mic. It should not be masked, obscured, hidden, or otherwise removed from the user's immediate awareness ability.

        Part of me wonders whether google got influenced via a national security letter, or got pressured by a committee to "enable" other, side industry players a way to make legit products. But, since it DOES appear fishy, I for now will presume various security agencies or wanton recklessness within google allowed this to happen.

        It is insulting, repugnant, and immoral to do or to allow something to depreive the user of the awareness that he or she is being or is capable of being monitored so easily.

        And, people anywhere I go wonder why I have electrical tape covering my tablet, phone, and laptop cameras. Plug up the mic with wax, and if anyone demands you conference with them when you cannot afford extra hardware devoid of private contents, tell them to toss off. Rationally make them understand that while you cannot prevent being physically mugged, you have NO obligation to facilitate electronic, remote ransacking by ANYone. If they scoff, they despise or disrespect you and your convictions/sensibilities. Why work with or facilitate or enable such people?

        Skype also can be hot-mic'd, I think, on conference room machines. My previous employer thought I was paranoid when I would bring up such things when setting up the dedicated Skype-enabled computer. I would suggest "doming" the machine, and that just pulling out the extended mic cable was not nearly enough to prevent the risk of confidential meetings in the Board Room being picked up by a wired-in remote observer. To be a little ominous, I mentioned laser-capture of voice, too. I guess such information stymies and cripples some companies. Honest ones, though, only have to worry about the risk of competitive information getting out, but at least not worry about non-existent corrruption or malfeasance.

        Users should have the right to an electronic "Face Toward Enemy" capability, "Enemy" being ANYone who surreptitiously penetrates the firewall -- poke them hard and finger them to hell and grep their asses to the trade rags. If you are a bona fide crim under investigation, and legit, verifiable warrants are properly executed, you're SOL. But, those who are not known to be in criminal or uncouth activities should have the right and means to thwart unwarranted, warrantless, and criminal observation. Why no analogy to good ole 'Merkun football? Screw one-sidedness. Fair's fair. Again, as long as you're not protecting crims or corrupt officials against non-crims.

      "Given that Google is the public-facing arm of the NSA..." If find that sort of statement utterly baffling. Yes, surveillance, broadly defined, is a business model for Google (and many, many others); we know this. And yes, this results in aligned goals between some private-sector players (although certainly not just Google) and public-sector espionage and law-enforcement agencies.

      But to say that Google is "the public-facing arm of the NSA" is such an oversimplification of an extraordinarily complex set of circumstances. I guess I find it annoying (and completely unhelpful) that people think about these issues in such simplistic terms.

For a start, it has to be a website your visiting that receives the mic data, you have to give this site permission and then you have to not notice a popup to even have this happen to you. Hardly going to help Google is it. The of course there is the fact that they are standards compliant, if the standards said they should not allow this and they did, then you may have a complaint but they don't.

    All that chrome

    I never used chrome, not that other options are all safe, but with chrome, it is unsafe by policy.

    For an innocent (?) explanation, the hidden mic could be the need of the hands free feature.

    Anyway, if you have downloaded any software for an OS which is not in a walled garden, there is always a risk of snooping, using social engineering. And since Chrome is being projected as an OS itself where websites are essentially apps, this anarchy is being extended inside the walls as well.

      Re: All that chrome

      Oh, come on, people! IIRC, even well before Chrome came into existence, surreptitious voice collection against the computer mic has been reported, IIRC, before 1997. It just wasn't talked about much in the public. Besides, the computer is just a big, fancy relfector and collector, and can be manipulated as an antenna -- transceiver, if you will -- by anyone with the proper tools and skills.

      All this means nowo is that when anyone is concered about privacy, wrap up the devices in matter what will disrupt smooth, useful capture of pulses. I dunno whether is sound mounting, or mounting on rocks or semi-wadded aluminium wrap, or hanging reflectors and white noise balls in a room while a fan randomly nutates/rotates to inject weird perturbations. I dunno. But, I bet wapping the phone and leaving it in the pocket still allow bone-retransmission to some extent, even if only 7 or 10 feet. Line enough public restrooms and transit vehicles and keep a current inventory, iti might be possible to hot-track anyone whatever state. (status) a phone is in.

      Don't forget lasers and keystrokes.... Every tool in the kit ensures some amount of collection and overlap...

      So, if you're into kinky sex, cheating, or just selling proprietary information, and can be identified to be in one or more of those categories, and frequent hotels, you better not take your phone into the room. Better yet, change up your meeting sites, and spend 4 hours trying to ditch tails and avoid f/r cams, hahahah. All this release is doing is "normalizing" most people. Artists in the trade of info dealing probably have skills and tools to thwart most "gotcha" Kodak moments that might otherwise land them in jail.

    The only way to fall victim to this is to allow a site to listen to your microphone?

    Would this exploit stop the microphone from displaying the "In Use" light on the mic? I have a webcam with in-built mic for Skype and the likes. Highly doubt that it can turn this off.

    1. dssf

      If THAT'S all you're wondering about, then ponder this:

      The mic possibly could continue to record even when you "turn it off". Even if you turn off the antenna, turn on airplane mode, and Faraday-cage it when not in use, it might work in concert with the accels/gyros and report what was audible at what lat/long or near what cell tower, or in what coffee shop or library said audio was captured. Then, when reconnected to a net, micro-bursted in small, non-lag/latency-affecting snippets neither you nor any sleuting tools you install could find. It doesn't even have to be the NSA doing this -- it could be slightly-advanced script kiddes, employers, suspicous spouses, police, data thieves, nosey neighbors, anyone who can find or employ the services of the kit or a person verse in its use.

      The notepads with all their rights-grabs... You type what you think is personal stuff not discoverable to anyone. But, you browse all sorts of sites, and gradually, multiple hackers are infesting your device(s), one or more competing for access to your stuff, your inner digital sanctum. You might begin to wonder why so much lag/latency/stuttery pages despite it being mostly text. Could be your photos and notes are being lifted with you unawares, or aware of the possibility, but, as long as you use devices you load with software from unvetted (not by reviews, but by a valid security team paied to help you keep your secrets protected beyong google's semi-empty gestures) sources.

      Just wait til you use a bonk/tap/rub-together device, or hug someone who is wearing a micrro-filament-antenna garment that can either access or short out electronics carried by unsuspecting targets.

      Application Permissions Required for Use:

      -- access to antenna

      -- access to contact lists

      -- access to keyboard

      -- ability to create, modify, and tear down ad hoc networks (without your knowledge, awareness, or consent)

      -- ability to blurp your location (without you knowledge, awareness, or consent)

      -- abiltiy to access sensitive logs

      -- abiity to modify (read, edit, delete) contents of the above

      -- ability to start services that cost you money

      -- ability to prevent the device from sleeping

      Not the way they going its not. I never even heard of Extended Support Release until Firefox 26. If this is progress, then count me as a Luddite... For starters I vote we bring back the old Download Manager, and keep the Menu Bar as well... It can't be that hard... But, it apparently is....

    2. paulf Silver badge

      Re: Firefox all the way !

      I'd love to say a wholehearted yes but its not as easy as it was. I still use FF as my main browser on all my machines - primarily due to ABP and Flashblock - but there seems to be a swing towards reducing stability of late which is worrying because it isn't being dealt with in preference to Awesome bars and such like..

      At home my i7 machine (Win 7 x64 home build and well specc'd with memory and MB etc) about 9 months ago I noticed that FF gradually got slower and slower until it reduced to a crawl over the space of 1-3 days. The only way to solve it is to kill and restart FF. A more permanent fix I found was to regress to version 17.0.1 and stay there until the other night when it managed to update itself to the latest v26 without my permission (killing things like persistent website logins and download history).

      Then separately about the time I upgraded my MacBook Pro (17" mid-2010 i7 Snow Leopard) to Firefox 24 I started getting Kernel Panics which increased when I moved to FF 25. In the 3 years to that point I'd never had a Kernel panic on that machine ever. Regressed to FF version 23 (last known version before Kernel Panics started) and I've not had a problem since (touch wood).

      The first problem Mozilla do seem to know about (from what I've found) but it isn't a high priority other than a Dev saying "we ought to keep an eye on this". I've not investigated the second Mac issue - as much as I'd love to I just don't have the time to debug other people's code.

      This isn't related to the number of tabs open before anyone asks - the older versions cope fine with the same number of open tabs/windows as the newer problematic versions.

      And as always YMMV.

          One of the first things I did was replace Safari with FF25, with updated versions of all my mainstay add-ons (NoScript, AdBlock, etc), and didn't do any further futzing around except to import my bookmarks from my old version of FF.

          FF25 has also been totally ace here as well. I'm sure that not going batso with tabs helps a lot.

        I've been running FF25 since November with no problems, though I don't use tabs, as I found them actually more confusing to deal with than separate windows.

        I've puttered around with Safari (spit) and Opera (m'eh) and went back to FF because, like yourself, I really loves me some AdBlock, NoScript and FlashBlock... not to mention DownloadHelper, for grabbing all those YouTube clips from Egypt, Syria, Turkey, Kiev, and Fullerton before they're "scrubbed".

    Turn the mic off

    There is an easy way to fix this. The most obvious solution is the one in the article - go into Chrome options and tell it to never touch your microphone and camera.

    The other solution is go into Windows Control Panel and locate the Sound control panel. Then just Mute the Microphone from there. That way, no matter what program tries to mess with your microphone they won't hear anything if it is muted.

    What is most concerning is the number of people who use Chrome but have no idea why. When you talk to them you find it has just been sneaked onto the PC as part of an Adobe Flash update or some other program. Most of my clients who are using it never chose it. With an underhand method like that for installing your product, this revelation of access to a microphone without full feedback on screen that it is operating does not surprise me at all.

    I make sure my clients realise Google is an advertising company and then ask them if they really trust Chrome...
