Major exploit found in Samsung models using Exynos 4210 and Exynos 4412 processors

0. phoneArena 16 Dec 2012, 22:49 posted on

An XDA member has found a vulnerability in Samsung Exynos processors 4210 and 4412 that could allow any Android app to takeover and control certain Samsung devices including the Samsung Galaxy S III and the Samsung GALAXY Note II; Samsung has already been alerted and most likely we will see a patch to cover the hole...

Actually, a variation on rooting seems to be a way to plug the hole (until Sammy releases a patch)....

The vulnerability seems to exist regardless of whether the phone has been rooted. All you have to do is install a malicious app that contains code that does the exploit, and your phone belongs to the exploiter. Until a patch is released, I may be putting my phone on airplane mode while it charges overnight.

I wouldn't worry that much about it, but I would say you should go under your settings and change it so that your applications do not automatically update.

I have been requiring manual updates to apps since I moved to Android back in 2010. Although there is some slight risk that malware was developed before the current publicity. Since my installed apps are from mainstream developers with at least 20,000 installs, I probably have limited (if non-existent) exposure.

Yes, and I believe that for the most part you would be safe just as long as you don't download or use any applications you suspect to exploit this security flaw. So, for instance, I don't think downloading and playing "Angry Birds" on your phone would open yourself up to this type of hacking. However, if you are the type to download applications from unknown or untrusted publishers then yeah you could have the potential of this happening.

Somehow, I suspect desire for attention on finding the exploit won out over prudence (notify Sammy and publicize the finding after a patch was released).

Its always good to alert users so they can be more mindful their actions. User need to install the dangerous app which sound like any malware to me. And to code one just for samsung phone is a lack of forth sight to me.

"And to code one just for samsung phone is a lack of forth sight to me."

How so? Between the 2 model CPUs involved, there has to be at least a couple of million vulnerable devices. Sounds like a target-rich environment to me.

How big was the "security update" in 2010 as far as Apple was concerned? Security by obscurity is M$ ways of claiming that system is more secure than others

There's a bitdefender article on Apple security in 2010 :)

It'd be a good idea to stop installing any apps or even updating existing apps till this is fixed.

Seems like an easy fix, just by removing the offending R/W permission. Samsung should release an apk to run this permission removal as a script asap.

Well, there is one BAD news and one GOOD.

1. BAD NEWS - Any app can take over the Root level access.
Samsung shall take care of this in upcoming days. So just be cautious while installing any new app even from Google Play store and look-out for the official patch from Samsung.

2. GOOD NEWS - You can root your device using this exploit.
Root your mobile device using the app developed by "Chainfire" (based on this vulnerability) with just one click. It is named as "ExynosAbuse v1.10". It is completely hassle free. This can be useful for those who can take some Risk but do not want to get into tedious "rooting" process.

If you have dropbox, your photo and pictures will be safe, because dropbox will auto upload all your photo once your data is opened...

That's all I can help, the rest you need to ask someone elae, sorry my friends
