New Android Exploit Discovered To Steal Data
mimd writes "A researcher at North Carolina State University has discovered yet another Android Browser exploit that affects the new Android 2.3 (Gingerbread) and previous versions. Slashdot recently covered a previous browser exploit that affected all versions of the Android Browser, but was patched in 2.3. Xuxian Jiang writes 'our finding here is that the patch contained in Android 2.3 is not an ultimate fix and can still be bypassed. We have a proof-of-concept exploit with a stock Nexus S phone and are able to successfully exploit the vulnerability to steal potentially personal information from the phone.' The exploit is capable of reading and writing files from an Android's sdcard or system partition as well as uploading user data over the internet."
Android, the Windows of the smartphone world.
Is the Nexus S still the only 2.3 phone available? I know Samsung and HTC have upcoming phones with 2.3, but as far as I can tell the Nexus S is still the only 2.3 phone you can get at this moment.
You'll see boobies. I promise
Seriously, the only way you can protect users is to take the phone from them. be consious about whatt youre doing with your phone. despite it acting like a computer that fits your pocket its still just a phone.
So just dont put anything you wouldn't want stolen on your SD card for now, until a confirmed fix is released :)
When Windows Phone has this kind of market share it will be the target of hackers too.
Oh, how I hate that meme.
Help stamp out iliturcy.
In other words, don't use the camera at all.
Its in line with the long standing tradition of slashdot to heavily report anti-ms news and hide linux/oss bugs. There are countless oss vulnerabilities being disclosed on security lists year after year and only about 10% make front page news on Slashdot. Its not a conspiracy, but its funny to observe the oss cheerleaders here..
gotta get those page views up.. ;)
Im not minimizing the problem or its potential consequences, but the article says:
For now, Android users can protect themselves by disabling JavaScript support in the browser, or by using a third-party browser for now.
So the problem is the browser, not the OS, and it can be circumvented by using another browser (what a lot of people do, for example Opera and Dolphin). Good to know, since I use Dolphin most of the time, and Firefox Beta (still terribly buggy) now and then.

The Nexus S doesn't have an SD card slot, I assume the exploit also allows uploading of anything in the phone's internal storage area but "removing the SD card" as a workaround isn't going to work on the Nexus S!

Wait, they can't just use Market to push out new browser updates? Something to do with the browser being integrated into the OS? (Yet all third-party browsers are not--can't google at least provide a second non-integrated but secure browser?)
Are you telling me that one of the *most complicated* applications on the OS which deals with untrusted data from the internet can not be updated? Did the android developers dream that the web browser will not have security bugs?
Then, did they just push out Android 2.3, *knowing that there was a security bug in the past, and likely to be more in the future*, and still provide no way to release updates to the browser?
Google, are you serious? </rant>
. /me updates Firefox with the hope of getting a less buggy version
I received a text message from someone I don't know that said "don't tell anyone with an iPhone, but there's another browser exploit in my Android phone!"
I kid, I kid.
My phone has too much sensitive data to allow just any random program connect to the internet. So, my default iptables policy is to drop all outbound packets except those matching a whitelist of apps (set by the app's userid). This includes not allowing uid=0 outbound access, in case malicious apps escalate to root.
:) as well as a personal assistant (data storage, GPS mapping, etc). I wouldn't give a random Windows desktop access to all that data, and Android is becoming very similar to any random Windows desktop (high marketshare of devices; many apps; apps are easy to install; apps can abuse their privileges or often request too many privileges; user base is willing to run any app they see on a whim => exploiters have motive and means to attack)
;) sometimes it's good to be different
DroidWall gives a convenient interface to manage the iptables rules (requires a rooted phone).
Yes, this is overkill for a regular user, and it cuts out a lot of the convenience of a smartphone (being able to run many internet-using apps). But for me it's less of a toy and more of a personal communication device (email, and yes, occasionally phone
On the other hand, the fact that very few "regular users" use iptables on their phone, means that exploiters have no reason to try to target and bypass it.
Combining a strict firewall with some prudence in which apps are downloaded/run results in a pretty secure platform.
(and yes, the data is encrypted/protected against physical loss and communication interception)
I would like to take this opportunity to tell you about my wonderful new application!!!

I don't really follow the smartphone scene, but aren't there some Android-based phones that currently can't be upgraded to a later OS version? Are owners of those phones just less secure, or are there patches available, if not full upgrades?
like most open source projects, the patch will be out in less than 2 days, then you can download, patch, compile and install. ohh, wait a minute ... where the the repo command in Android?

Sadly in the current state of Android, only a fraction of current phone owners will ever get the update.

great! i will fill up the memory and bog down the whole device (As if it wasn't already sluggish and laggy) by using third party apps which are *as well* not trustworthy. AND have ads! yaaaaay!
I do. Why don't you too? ;)
Just use Windows Mobile 7 which steals your data out of the box.
Maybe I'm reading this wrong, but it seems like if you d/l a different browser, you're good?
(Though I'm actually glad Market doesn't automatically update stuff unless you specifically request it to check for updates; sometimes updates can suck. What Google SHOULD do is inform you of your options (d/l update; get new browser; turn off j/s), but I don't want them putting anything on my phone w/out my knowledge. That's so... **apple/microsoft**)
