[APP][1.5+] aScanmem game cheating/debugging utility

Fake-nik-doesnt-make-diff · Jan 3, 2014

I have finally found time to put it together, so welcome aScanmem - simple graphical frontend for scanmem game hacking utility (or at least it is supposed to be that, but currently it is more of command line than GUI). Scanmem uses Linux debugging API to read/write process memory, which allows one to do variety of things from changing single variable in target process to hot-patching byte ranges and more. It has most of features, available in other scanmem-based cheating tools (GameGuardian etc.) and it's selling point is.. being open source, I guess? Well it is developed by myself, and that's all I care about.

Screenshots:

Currently implemented features:

Screen overlay button, for launching scanmem from other apps (aka GameCIH Toolbox)
PID is autodetected
Screen overlay console to scan memory of application without leaving it's activity
Simple process browser (mostly useful for finding out PIDs of Services)
Some level of automation in all of above
Frontend and scanmem are protected from Out-Of-Memory killer
Some documentation, including scanmem manpage in html format
Scanmem 0.13 with few later commits (including fixes for crashes) built for ARMv6/7, x86 and MIPS.

Backend features:

XDA seems to hate new members, so I am not giving you links to scanmem upstream and aScanmem source code. You can find both with Google, if you want.

From what I understood, this isn't the typical "game cheating" app. It allows you to "see" what's stored in the memory, including app values (or game values), search for specific values and modify them. Technically, it should work with every game/app unless it brings some sort of memory protection.

I have tested it with both native ports (Plants and Zombies) and pure Java Android apps (Andor's Trail). In theory it should work with any app, not using some form of memory encryption. At least all apps, that can be hacked with GameGuardian should work. Scanmem supports following data types:

8, 16, 32 and 64-bit integers
16 and 32-bit floats
strings (only in native code, no Java strings)
byte masks (also can set byte masks)
generic types (all integers, all floats)

It also supports fuzzy search (aka search for unknown value). Here is the site: http: // code.google.com /p/scanmem/

Version 1.0.3 is out. Main changes are more foolproof PID detection method and fix for annoying crash, which used to be caused by "shell" command. Please test and share your opinion on the app before I start uploading it to markets.

Got Process killed by signal 7

I tried your app and when i pushed the scan button scanmem told me that xxx suitable regions found. When i try to search for a value i get the message: Process killed by signal 7

AFAIK signal 7 is a bus error.

I compiled your code and copied only the scanmem binary on my device (Nexus 7 2012) and with the scanmem binary itself i can search for values without getting a bus error.

I don't have Nexus 7. Can't confirm on neither of my devices and in emulators. Have you tried other versions / in different applications?

Please post your ROM version, and, if possible, kernel config.

Which NDK version have you used? Could you build debug and release builds and check if both work?

No, only tried Version 1.0.3. Wiht two applications (Royal Envoy and Bloons TD5)

Fake-nik-doesnt-make-diff said:

Adroid 4.4.2 (factory ROM, rooted)

Fake-nik-doesnt-make-diff said:

NDK version is r9c (64-bit).

When i have time, i will test it on my Nexus S as well.

Update:
Tested debug build on Nexus 7 an got Bus Error when i tried to search for a value.

Build again as release and scanmem binary is working as expected (scanmem -p xxx -b)

Update 2:
I added this lines to the .mk file:
APP_OPTIM := release
APP_PLATFORM := android-19
APP_STL := gnustl_static
APP_ABI := armeabi-v7a

Hi,

tried ProcessChooser-1.0.3.apk on my Nexus S today.
Again got a Bus Error.

Android Version: 4.3.1
Cyanogenmode Version: 10.2.0-crespo
Kernel Version: 3.0.101

I am a bit busy with things, but there is an interesting work being published here, which I most likely will incorporate ASAP. I wonder, if those changes are enough to fix memory access issues you are suffering from.

Ya, I have a Nexus 7 (2013) and when I search for float I get: I/O error or process closed by signal 7.

Nevermind I got it to work (didn't use the -b switch).

How to 'move' the start scanning button?

cburon · Oct 21, 2014

I tried it on my Asus memo pad fhd (ME302C) and I have to say that this is the first memory reader that actually does work with my cpu architecture. You have done a wonderful job.
I would suggest that perhaps you improve the interface.
Thanks a lot.

lua script engine + standalone app

is the project still on? a lua integrated script engine will be good to add

and make a standalone release for it.. for custom gui .. for vip cheats xD

Atronid · Aug 21, 2018

Impressive work. It's a shame this app is not known enough, I was such deceived there were no Scanmem or Cheat Engine-like app for Android that I started to build one, but now I know your app I rest my case xD

Just one question: the phone I tested the app on is rooted and run on Lollipop. But I when I try to scan I get a message:

Code:

error: only position independent executables (PIE) are supported

I have no idea what's the problem, and it is not referenced in the FAQ.

Any idea?
