Bug In iOS, OS X Allows AirDrop To Write Files Anywhere On File System
Trailrunner7 writes: There is a major vulnerability in a library in iOS and OS X that allows an attacker to overwrite arbitrary files on a target device and, when used in conjunction with other techniques, install a signed app that the device will trust without prompting the user with a warning dialog. Mark Dowd, the security researcher who discovered it, said he's been able to exploit the flaw over AirDrop, the feature in OS X and iOS that enables users to send files directly to other devices. If a user has AirDrop set to allow connections from anyone—not just her contacts—an attacker could exploit the vulnerability on a default locked iOS device. In fact, an attacker can exploit the vulnerability even if the victim doesn't agree to accept the file sent over AirDrop.
This bug has been known for a year or so. Possibly more.

Of course the bug is worrisome, but then, I consider the setting that allows it—leaving AirDrop open to everyone—to be a pretty ridiculous personal security flaw. Making one’s phone readily available to connections from random sources for the sole purpose of file drops doesn’t sound like something that should make the least bit of sense to even the average user.
Use it or lose it.
I wonder why people would immediately bash on Windows and keep defending apple's crap. Somehow double standards here.
Fucking a fat girl is like riding a scooter... it's fun 'til someone sees you.
It's a bug, not yet another NSA/GCHQ backdoor that offers Apple "deniability" of their collusion with intelligence agencies.
"If any question why we died, Tell them because our fathers lied."
See subject: This is a case of do NOT leave it open to "everyone so it just works" - & it should be the opposite.
* In terms of Windows, I've always felt that YOU the user should be allowed to setup features YOURSELF - by that, I mean do NOT just "leave all services running by default" for example, but instead, during setup, allow YOU the user to be asked "Do you want REMOTE REGISTRY on, Yes, or No" for example (with an appropriate explanation of what the downsides MIGHT be should one make it active).
Not just services either (which the less of them you run, you go faster, but also more than potentially more secure also by not leaving "doors open" @ all) but, also other features.

P.S.=> In any event, this is the price of "it just works immediately outta the box" - potential security exploits as well as slowing you down performance-wise (especially running things by default you may NOT need or use @ all)... apk
Don't use Airdrop so problem fixed. I'm not much in the Apple in general in terms of services and applications. Like the OS and the hardware. Not a fan of everything else. Apple generally get's in trouble with this stuff because they dumb down everything so it works. Thinking because it only connects to Apple devices it must be safe, right? Obviously the numbers of IOS devices makes them a better target now and hackers are finding exploits which many of us knew were always there just that nobody really cared. Android is still king simply because so many idiots jail brake their Android devices and open themselves up to hackers. Apple is by far much less exposed, and the fix for this Airdrop exploit is the IOS 9 upgrade. So if you use Airdrop get IOS 9 soon.
I'm suprised they got Airdrop working at all.
If you don't have the latest and greatest hardware at the time of release it won't work at all.
That's the new "planned obsolescence" I guess.
If a user has AirDrop set to allow connections from anyone—not just her contacts—an attacker could exploit the vulnerability on a default locked iOS device.
What the fuck is wrong with using the word "their"?
Although...
Mark Dowd, the security researcher who discovered it, said he's been able to exploit the flaw over AirDrop, the feature in OS X and iOS that enables users to send files directly to other devices.
Perhaps Mark Dowd is female. If so then... Hmm. Then... I dunno.
Either way, there are a whole group of words that are not gender specific. Use them(!), and stop with this retarded "her" crap.
Thanks.
Check to see whether it's disabled already, open a command prompt and run:
defaults read com.apple.NetworkBrowser | grep DisableAirDrop
If it returns DisableAirDrop = 1, then you should be fine. If it comes up blank, or if it shows DisableAirDrop = 0, then AirDrop is not disabled by default. In this case, run:
defaults write com.apple.NetworkBrowser DisableAirDrop -bool YES
You'll need to log out and log back in for the change to take effect.

Finding God in a Dog
It does not matter if you have switched off airdrop or restricted its access to known contacts.
At a border crossing an officer can take your locked device and push some nasty payload to it.
Even a confirmation would be useless as it would be another guy pressing okay.
See subject: An "express" vs. "custom" setup is a GOOD idea - point taken/agreed.

...a kernel issue, rather than an issue w/ iOS or OS-X? Wouldn't they have to look at XNU and debug that?
"If a user has AirDrop set to allow connections from anyone..."
Ok, so you have a setup where people can push files at you, and if you allow anybody to do it, someone might drop a malicious file in your system? What about the fact that Apple allows you to leave your laptop unattended and unlocked, say, on the subway? A malicious person could take over your whole computer! That's a serious vulnerability, and proves that Macs are no safer than Windows machines.

You can enable airdrop on the lock screen by default. So even if you have it disabled, if an attacker has temporary physical access, they can re enable it
"Under normal circumstances, when the app is first installed on a new device, the device would throw up a dialog asking the user if she trusts the app. However, Dowd is able to suppress this prompt by installing an enterprise provisioning profile on the device and marking it as trusted."
How you gonna install enterprise provisioning profile onto the target device in the first place? Is that guy called Mark Dowd really a security researcher? Professionally? Not by hobby?
