[Q] Q: Perm/Temp roor & S-OFF - security concerns. - Android Software/Hacking General [Developers Only]

I spent much time searching, but fail to find answer to these questions:
1.- In an device with S-OFF: - can other than SuperUser apps touch any system data ?
2.- if an device is temp-rooted, then only SU-apps* can touch S-OFF'ed data areas ?
(by "su-apps" i mean apps that got granted "superuser" rights by "superuser" app)
3.- Visionary can temp root on each boot, or perm root - what's the difference ?
4.- does perm-root grant full rights to every application ? (so that any app can read any part of data it wants anytime ?)
5.-provided that I use S-OFF and temproot, - what secutity risks did I enable, provided that I trust the few applications that I allow to run as superuser ?
Thanks.

bump - anyone knows ?

Perm.Root, Basically Only Allows You To Have Root Access After A Reboot, Compared To Temp.Root, Which Requires The User To ReRoot After Every Reboot!!
No Matter Temp.Root or Perm.Root, You Still Have To Grant Which Ever App SU Permissions, For It To Run!!
Install "Lookout Security" If Your Sceptical Of A Certain App!!
Hope This Helps!!

Makes sense, but why does f.eks visionary have option to "temp root on each boot" ? - something is supposed to be different.

[Q] Do all applications get root priviliges on a rooted android phone?

Or what is the exact mechanism behind this in Android? I have been using GNU/Linux for many years so I understand the original concept and would not want every app to have root privileges.
The Superuser app allows you to accept & deny all root apps. You can also choose to always allow certain apps, but you don't have to.
I don't quite understand this. Who gives the apps the privileges. I suppose the Superuser app is only the frontend for some system service. And does it work as a white list or as a black list. Meaning: Does every app get root priviliges by default on a rooted phone or do I have to manually give root privileges to desired apps but the rest doesn't even realize it's on a rooted phone.
By default, apps are denied root privileges. If I restore an app that runs as root in the background -along with its data - the app won't work until I launch it & grant it superuser permissions. Droidwall is a good example of this. Droidwall works by denying or allowing 3g and/or wifi access to apps based on your input. It does this by changing the iptables. If I flash a new ROM & restore with Titanium Backup, I usually forget that Droidwall isn't doing its job until I notice ads in an app that isn't supposed to connect. Once the app is launched & I choose to apply the rules, Superuser prompts me to allow the changes. If I do not make a choice within 10 seconds, SU automatically denies the root request.
In short, an app will never run as root (aside from superuser itself, if that counts) without you first allowing it. Also be aware that most everyday apps will never ask for root access as they don't need it to run. Only apps that are making changes to the system (reading or writing) will need root access. As far as accessing your contact data & other stuff you may worry about, any app can do that if it has permission (not root) to do so. When you first install an app, you will see a list of permissions - usually an app needs those permissions to run and there's nothing to worry about.
OK, thanks I understand it more now. What would happen if I didn't install Superuser. Is there a built in daemon for superuser privileges?
Don't fight the powers that be. Install superuser. You need it.
I'm pretty sure you'll get error messages from most root apps. I could be wrong, though. Next time I'm about to flash a new ROM, I'll remove Superuser after I do my backup, just because I'm curious. I'm pretty sure that Superuser or an alternative - if one exists - is necessary. I know the ability is there in the os, but I would think that it would need some kind of vehicle (such as an app) to relay the information. I certainly hope apps wouldn't automatically be granted root privileges, but I'm not sure. It's an interesting question, though.
Roms come pre-loaded with Superuser, and any auto-root method does as well. You would only be without it if you root manually, stay on stock, and choose not to push the app. Or, I guess, if you choose to remove it.

Answers:-
1. Uninstalling of superuser with clean Unroot will Remove Root Binary from System and will effect Root, as without SU app you cant play with Root..
2. No, You Can't.
3. No they won't Function. You can uninstall Root apps if they are in System Folder other you will be able to uninstall.

Thank You very much.. I am satisfied by your reply..
But tell me one more thing what superuser does.. i think superuser app only gives the permission to the root apps to install something in root area.. right? superuser app work is just to allow or deny the permission to the app right..?
So if i don't unroot my phone and if i just simply remove superuser app then i still should be able to install root apps in the root? because my phone is rooted.. and i have just removed superuser app which gives permission only.
I think superuser only gives the permission to the app SO apps will be intall in the root just without any permission of superuser?? this is what superuser does ONLY?
I think i am misunderstanding something about superuser.. Correct me please if i am wrong.. :good:

Yes,
It gives permissions to access, modify your Root area[Restricted when you are Non-Rooted].
No,
Removing SU app will remove permissions with It. So after that you cant use those Rooted app which you gave Permissions when u had SU App.
Note:- Without any SU app you can't Play your System Files..
nor your rooted apps will work..

This is the link I started dealing with:
http://forum.xda-developers.com/showthread.php?t=2565758
Problem is, I uninstalled a system file or two...or 15...and now the phone will start up, but no apps show up, just black screen. I can navigate still and work around it, but what i CAN'T do is give permission to that batch file once it recognizes the phone.
Obviously, I didn't know what I was doing, so I didn't realize that unrooting it wouldn't solve the problem, so I need to root, and then somehow get my system files back in place. Titanium Backup says my back up doesn't exist...pretty frustrated, I've spent 10+ hours on this site and some others trying to get back in, so I apologize upfront for possibly missing a post elsewhere

Giving su rights to an app on a not rooted device

Hey guys,
This is the wrong place forum, but I like you guys, so I will ask you a question
Say there is an app that requires root (in this case Cisco AnyConnect rooted version), but I do not want to have root access enabled from within Android OS. Is there a way to install the app with automatic root access? E.g. by flashing it from within the recovery?
Thanks,
Su
Do it need root access or system permissions ?
If it needs root, you must have "su" in android OS.
If it needs system permisssions, you could push it in /system/app/ or /system/priv-app/ (more access than /system/app/)
Hmm, from the description, it seems like root access... ah well, from the CM11 SuperUser settings, seems like it is possible to automatically deny root access to all requests, and only allow selected apps.
Perhaps this is a better way to set up the device...

every app that wants SU permission should be prompting you the first time to allow or deny it.
if any app gets SU permission without you allowing it, something is wrong.
what i dont understand is, you said the phone is NOT rooted, then mentioned cm11. if you are running cm11, your phone is already rooted.

[Q] Looking for a way to make an app think a device is not rooted

I have a certain app that I need to use that will not run on a rooted device. My root app is SuperSU, and by disabling superuser in the settings the app will run, but I can't make it work without disabling it. It doesn't even give me a prompt to ask for root permission - the app must just be looking somewhere for the su binary or something.
Is there a way to make an app think that a device is unrooted without disabling root access?

Xposed framework with Root Cloak module. It doesn't always work, but it often does, so give that a try.

root rights without rooting

I've got hope. The GSAMBattery app said it needs rights to display more data. If you have root, the app does that for you. If not, you should enter this command:
adb shell pm grant com.gsamlabs.bbm android.permission.BATTERY_STATS
The way I see it, it simply means that I'm granting rights here that I could otherwise only do with root. Now the question: Is it possible with ALL rights? I would need the superuser for the App Automate, so that it can automatically move my device into the flight mode and out again.

Try this
You can use Magisk root and use Magisk manager to hide root status from your device to use all applications.:laugh:
Thats not the point. Huawei doesnt give away unlock codes anymore (dont know why) and I also want future OTAs. So actually rooting is no option.
I just wonder bc the line above IS some kind of acting as root. So isnt it possible to gibe rights to other apps the same way?
Is it not possible? Then why did it work with the battery app?

The command that you used is not the same thing as root permissions, you merely granted the app permission for a certain action. No, you cannot use this methid to acheive the sane thing as full root permissions for all apps.

I dont want to do a full root permission with this command. The app Automate need "superuser" rights for putting the device in flight mode. I only want to grant that one for the one specific app.
