Thanks for all you do.

Ancel ROBINSON commented on 2012-12-18 at 20:33:

Good question

Roberto Radaelli commented on 2012-12-18 at 20:50:

Avast tells me Exynos abuse is a trojan and asks me to uninstall, what should I do? (my noobness has no limits)

Ancel ROBINSON commented on 2012-12-18 at 20:53:

Chainfire, is there a particular place to post questions about Exynos apk?

Thanks for looking out for the community you're a saint man

Bjørn Helge Eldevik commented on 2012-12-18 at 21:28:

Thanks Chainfire, you blocked the hole! Seems Supercurio copied your code in his latest version.

Adnan Majeed commented on 2012-12-18 at 21:35:

Great work bro. Keep it yo.

Chainfire commented on 2012-12-18 at 21:39:

+Bjørn Helge Eldevik Without even looking at it or testing it, I'm guessing he is delaying the loading of other programs (which only works in very specific case) by making his receiver blocking. Which in some cases works - but in no way does it change the fact that his method is fundamentally flawed, and it still leaves holes left and right. 

I have no time to look at it now, maybe tomorrow !

But what about perseus kernel that has patch built inside?

Chainfire commented on 2012-12-18 at 23:27:

+Giuliano Peretti if you read the article you will find it actually mentions the kernels

Timothy Pleines commented on 2012-12-18 at 23:31:

I will do what I can to get a few more people to read this, right now the media has them all in a frenzy. I am not very popular on the internet but I will retweet and all that nonsense.

SE Android allows us to mitigate this completely. I'm in the process of bringing SE Android up on a Note 2 which has /dev/exynos-mem and am writing the policy very carefully to only allow things that absolutely need access. http://selinuxproject.org/page/SEAndroid if you haven't heard of it...

Giuliano Peretti commented on 2012-12-19 at 07:26:


Sorry but I read " We're going to talk about three solutions here:RyanZA's ExynosMemFixSupercurio's Voodoo Anti ExynosMemAbuse v0.6Chainfire's ExynosAbuse APK" nothing about perseus kernel, and searched but nothing, maybe my fault 

Tomi Jenson commented on 2012-12-19 at 08:55:

+Giuliano Peretti I think what he means is that the real fix is using custom kernel that already patch the exploit

Chainfire commented on 2012-12-19 at 09:42:

+Giuliano Peretti If I use the browser's search function to search for kernel in the page, on line three, I find: "the only true solution is a kernel fix"... seems clear to me.

Shiraz Adil commented on 2012-12-19 at 15:13:

Thanks for the article and the patch Chainfire. Good read. With any luck Samsung will respond quickly.

salvatore corallo commented on 2012-12-20 at 06:52:

John ara commented on 2012-12-23 at 09:02:
