There is a new API in town! HTML5 will (soon) let you make the user's device vibrate. What fun! Obviously, bukkit plugins it's useful for triggering alerts, improved immersivness during gameplay, and all sorts of other fun things like sending Morse Code messages via vibration .
At the moment, Chrome (and other Android browsers) ask for permission before accessing features such as geo-location, camera, address book etc. This is a security measure to prevent your private information leaving your hands without your knowledge.
At the moment, accessing the HTML5 Vibrate API doesn't trigger an on-screen warning. Its use is seen as pretty innocuous. Because, realistically, the worst it can do is prematurely drain your battery. Right?
Suppose a malicious web page pops up a fake system notification and vibrates at the same time. How confident would you be of telling the difference between a legitimate pop-up and a .png on the web page you're viewing. After all, the phone buzzed - so it must be genuine.
Autoplaying sound on adverts in annoying - auto-vibration could be just as irritating. Imagine searching through tabs until you found the single advert which was pulsing away trying to get you to buy new insurance.
For now, the intensity of the vibration cannot be controlled - only the duration. It is not impossible to conceive of malicious bukkit plugins code being able to exploit an unpatched browser flaw and overdrive the motor to destruction. Faking Telephone Calls
When combined with HTML5 Audio, it would be possible to create a fairly realistic "Incoming Call" screen which vibrated and played a ringtone. Once "answered", the page could play some audio which says "Hi, can you call me back urgently - my number is [premium rate line]" and then, perhaps, automatically open up the dialer using the tel: URI. Could you tell if the above was a real phone call? If you looked closely, probably, but when the browser is playing your phone's default ringtone bukkit plugins and the handset is vibrating, bukkit plugins it would be pretty bukkit plugins easy to be confused. Combine bukkit plugins it with a WebRTC call and you're looking at a very convincing scam. Video Demo

Firefox bukkit plugins was the only browser I found which supported Vibrate - on Android, neither Samsung's browser, Chrome, or Opera did - iPhone also doesn't yet support it. No one cares about Windows Phone or BlackBerry - so I didn't test them*.

Re "Imagine searching through tabs until you found the single advert which was pulsing away trying to get you to buy new insurance.", the vibration API spec is pretty clear that you should only vibrate from a visible Web page. And I expect bukkit plugins that if vibration proves to be used annoyingly, browsers may end up providing easy way to mute "web sites", or even handle them as they have handled pop ups.
Re unpatched browser bukkit plugins flaw destroying the motor, it would also have to be on an OS that doesn't prevent applications to do so; and if one starts from a flawed browser, then no permission grant in the world would change anything to the problem (because you could then also assume that that permission grant could be buggy).
While vibration may add credibility to your (clever) pseudo-call attack, arguably the audio and visual aspects are sufficient to make it convincing on its own. I think the real attack vector here is that calling an innocuous looking bukkit plugins number can cost you money.
I guess the case can be made that users don't expect Web pages to have certain capabilities, and the surprise this creates can be exploited maliciously; but that's probably true of any new capability, and unless we want to gate any such new capability behind a browser prompt, this is probably bukkit plugins unavoidable.
Thanks for your comment. I agree that some scenarios are unlikely. Its real danger, as you've identified, is that unexpected behaviour can lend credence to an otherwise obvious attack. For example, if you take a look at this fake "Android virus alert" - how much more convincing would it be if the phone vibrated with its "alert"?
I worked on this feature for Chrome on Android, and this is our current approach. bukkit plugins Vibration will stop when the user: * Navigates away * Reloads the page * Switches to a different tab * Closes bukkit plugins the tab * Sends the browser to background * Turns the screen off
Also, if the user doesn't like the page, he can close it and not go there again. It is the most basic way of user control in a browser, and proven bukkit plugins to be quite effective. If it turns out that this feature really does get abused a lot, like browser popups did, then we'll have more data. This would give better insight into how to counter the abuse without degrading the user experience for valid usage. Reply Alice Wonder (@AliceWonder32) Jan 10, 2014 15:03
