Riru - MomoHider (aka IsolatedMagiskHider)

Deprecation Notice

Hi, today is 2022/2/1, happy Chinese new year!

One year ago, I made this project because my bank app detected the device is rooted and reject to run. Initially I just want to help others so I made this public. But in the past year, things are not going the way I want -- someone just downloads my module, changes the author and claim it's their work; more seriously, my module with unknown changes was built into a cheat program. Finally my kindness ended up being a tool for outlaws. So, I chose to develop a new hide module "Shamiko" with other developers in the LSPosed team. The new module will only support Zygisk, and provides more functionality than MagiskHide. I believe the module will be the complete solution if you want to use MagiskHide on Magisk v24+! But, To keep things from getting out of hand again, the new module will NOT open source, and rejects any modification.

We expect to officially release Shamiko on February 2nd. Click here to download Shamiko.

Background

Many applications now detect Magisk for security, Magisk provided "Magisk Hide" to hide the modified traces but not completely hidden, magisk still can be detected by MagiskDetector. This module tries to make it more hidden.

Features:

Config name	Description
isolated	Apply Magisk Hide for isolated process and app zygotes. This feature is deprecated because it will unmount Magisk modified files for every isolated processes, and the unmounting time cannot be well controlled, which may cause some modules to not work. For almost apps, Magisk Alpha or the latest Magisk canary + Riru-Unshare is enough.
setns	Faster new way to hide Magisk in isolated processes. Requires config "isolated" is enabled.
app_zygote_magic	Make "Momo" (a root detector app) cannot detect Magisk hide is running.
initrc	Hide the modified traces of init.rc

Note: Since 0.0.3, all features are disabled by default, you need to create a file named /data/adb/(lite_)modules/riru_momohider/config/<config name> to enable it.

Requirement

Rooted Android 7.0+ devices with Magisk and Riru V25+.

Test

Momo is the strongest detection app known.

I have studied MagiskHide and found some issues. My module cannot deal with them. I suggest you updating Magisk and use other ways to hide root. Staying on an old unsupported Magisk version is meaningless. Stop cheating yourself.

Troubleshoot

Find the "config dir"

The really config dir is $MODULES/riru_momohider/config. For Magisk-Lite, the $MODULES is /data/adb/lite_modules; For the original and other forks, the $MODULES is /data/adb/modules.

If the module doesn't work, please check the config dir first. You should see a file called magisk_tmp under the config dir.

Momo shows "environment is broken, service not responding"

Please check your "overlay modules" first. Iterate through $MODULES and check each of its subfolders. For overlay modules, you should see system/vendor/overlay or system/product/overlay under it.

If you can't find any overlay modules, please go to the "without overlay modules" section.

With overlay modules

Check your android version. For Android < 10, Magisk Alpha or the latest Magisk canary + Riru-Unshare is almost enough. After installing the recommended things, you can turn off isolated and try again.
Disable overlay modules if possible. Or, we can't support this case yet.
Try again. If the problem not solved, please try the "without overlay modules" section.

Note: We needs more info to try to support overlay modules, please file a issue with the full log and stacktrace to help me to solve it even if you have solved the problem.

Without overlay modules

Turn on setns and try again.
If the problem not solved, please file a bug with your device info and full log.

Momo still shows "environment is modified"

MomoHider only hide "MagiskHide is enabled", "Found su file", "Found Magisk" and "init.rc is modified" for momo. If you not see these, this is not our problem, please hide it yourself.

But if you see these after enabling these features... please check the following steps:

Try run magiskhide exec which su, if you see something found, this usually indicates that there are other superuser programs in your system that cause magiskhide not work properly. Please remove other superuser programs.
Try installing MagiskDetector, if you see "magiskhide not working", then report to Magisk.
Report to me with your device info and logs.

There is our suggestion:

Always keep SELinux is enforcing and make sure any sepolicy rules is necessary.
Use modern Xposed framework implementations (like LSPosed or Dreamland ) and do not use "global mode", only enables Xposed for actually needed apps.

Build

Run gradle task :module:assembleMagiskRelease from Android Studio or command line, magisk module zip will be saved to module/build/outputs/magisk/.
