Samsung's TouchWiz vulnerable to one-click data wipe or reset attack (video)

Samsung's TouchWiz vulnerable to one-click data wipe or reset attack (video)
Over at the Ekoparty security conference, Ravi Borgaonkar presented a session titled “Dirty use of USSD Codes in Cellular Network”, and what do you think was used for the demonstration?

Samsung Androids with TouchWiz, of all things. The guy demoed how a single line of HTML code can wipe the data on such handsets if you click it, since TouchWiz has a feature that automatically dials a code when a link is tapped.

The same goes for QR scans and NFC - Samsung's TouchWiz UI makes the dialer automatically execute the sequence, which can potentially force a factory reset code onto your unsuspecting phone, and wipe your data. Here is a video demonstrating the theoretical disaster.

yeah guess the S3 did get owned but lets face it, unless someone deliberately tries to do this, its not likely for it to happen At least this is something that can be corrected quite easily, but lets see if it does get corrected

Chances of you receiving that through NFC? 0.000257812%.

A good thing is, there's tons of solution for this. Change a ROM if you want to :)

You can also just download a different dialer, then you'll be prompted first.

touchwiz UI is the most boringest (if there is word for that) UI you can ever get on an Android platform device literally.

It is just a test nothing will harm your phone.

Another reason added to my list of why Touchwiz is not to be trusted.

I love HTC Sense. Back in the day I preferred my OG EVO over the SGSII even though the screen was beautiful it still felt like a downgrade going to Touchwiz

Does this affect everyone or just US PHONES... verge reports they only got it to work on a at&t s3...either way let's hope this is fixed ASAP and should not be a problem unless you or on dodgy sites

Come on, Samsung. Address this. It should be as easy as having a confirm factory reset dialog box poo up for all hidden code disks.

Per another android site: Update: This issue is, unsurprisingly, a lot more nuanced than the video here lets on. The bug is based in the stock Android browser, is in fact quite old, and has been patched in more recent builds of Android - this is probably why Nexus devices running the most recent OTAs are unaffected. The fact is, this is not a Samsung problem, it's an old Android problem that has been known about for some time. Any of the U.S. SGs3 that have their OTA updates aren't able to be affected.

touchwiz has crashed on my s3 so many times

Really? I don't think I've had TouchWIZ crash even once in the two months I've had my GS3. And I tinker a lot.

^ This. And I've managed to reach 1.56GB of RAM of 1.59 and it didn't crash or lag, at all.

@ Phonearena. This has been confirmed to be a vulnerability of the stock Android browser. A fix for this hack was released with the latest Jelly bean update. Therefore, the hack will affect any android device running previous versions of Android. You can use a simple google search to confirm this info. Please update the post. Thanks. Jokesy
