README

trueseeing is a fast, accurate and resillient vulnerabilities scanner for Android apps. It operates on Android Packaging File (APK) and outputs a comprehensive report in HTML, JSON or a CI-friendly format. It doesn't matter if the APK is obfuscated or not.

Capability

Currently trueseeing can detect the following class of vulnerabilities:

• Improper Platform Usage (M1)

  • Debuggable
  • Inadvent publishing of Activities, Services, ContentProviders, BroadcastReceivers

• Insecure Data (M2)

  • Backupable (i.e. suspectible to the backup attack)
  • Insecure file permissions
  • Logging

• Insecure Commnications (M3)

  • Lack of pinning (i.e. suspictible to the TLS interception attack)
  • Use of cleartext HTTP
  • Tamperable WebViews

• Insufficient Cryptography (M5)

  • Hardcoded passphrase/secret keys
  • Vernum ciphers with static keys
  • Use of the ECB mode

• Client Code Quality Issues (M7)

  • Reflectable WebViews (i.e. XSSs in such views should be escalatable to remote code executions via JS reflection)
  • Usage of insecure policy on mixed contents

• Code Tampering (M8)

  • Hardcoded certificates

• Reverse Engineering (M9)

  • Lack of obfuscation

Installation

NOTE: As of 2.1.9, we are on ghcr.io. (Docker Hub is somewhat deprecated)

We provide containers so you can use right away as follows; now this is also the recommended way to run:

$ docker run --rm -v $(pwd):/out -v ts2:/cache ghcr.io/alterakey/trueseeing

If you want to run statelessly you omit mounting volume onto /cache (not recommended for day-to-day use though; also see #254):

$ docker run --rm -v $(pwd):/out ghcr.io/alterakey/trueseeing

Finally if you would like to use plain old installation (e.g. for interacting with devices), you can do as follows:

$ pip3 install trueseeing

Usage

With trueseeing you can interactively examine/analyze/patch/etc. apks -- making it the ideal choice for manual analysis:

$ docker run -it --rm -v $(pwd):/out -v ts2:/cache ghcr.io/alterakey/trueseeing --inspect target.apk
[+] trueseeing 2.1.9 [inspect mode]
ts[target.apk]> ?
...
ts[target.apk]> aa
...
[+] done, found 6403 issues (174.94 sec.)
ts[target.apk]> i
...
ts[target.apk]> gh report.html

Non-interactive scan

Alternatively, you can scan an apk with the following command line to get findings listed in stderr:

$ docker run --rm -v $(pwd):/out -v ts2:/cache ghcr.io/alterakey/trueseeing --scan target.apk

To generate a report in HTML format:

$ docker run --rm -v $(pwd):/out -v ts2:/cache ghcr.io/alterakey/trueseeing --scan -o report.html target.apk
$ docker run --rm -v $(pwd):/out -v ts2:/cache ghcr.io/alterakey/trueseeing --scan --format=html -o report.html target.apk

To generate a report in JSON format:

$ docker run --rm -v $(pwd):/out -v ts2:/cache ghcr.io/alterakey/trueseeing --scan --format=json -o report.json target.apk

To get report generated in stdout, specify '-' as filename:

$ docker run --rm -v $(pwd):/out -v ts2:/cache ghcr.io/alterakey/trueseeing --scan -o - target.apk > report.html
$ docker run --rm -v $(pwd):/out -v ts2:/cache ghcr.io/alterakey/trueseeing --scan --format=html -o - target.apk > report.html
$ docker run --rm -v $(pwd):/out -v ts2:/cache ghcr.io/alterakey/trueseeing --scan --format=json -o - target.apk > report.json

To fix (not all) problems it catches (deprecated):

$ docker run --rm -v $(pwd):/out -v ts2:/cache ghcr.io/alterakey/trueseeing --patch-all target.apk

Building

We are using flit as our build system. Please do something like the following to build:

$ git clone https://github.com/alterakey/trueseeing.git wc
$ docker build -t trueseeing wc

If you are to hack it, do something like this instead (i.e. pulls tools needed to validate the code; namely mypy and pflake8):

$ git clone https://github.com/alterakey/trueseeing.git wc
$ cd wc
$ python3 -m venv .venv
$ source .venv/bin/activate
(.venv) $ pip install flit
(.venv) $ flit install --deps=develop --only-deps
(.venv) $ (... hack ...)
(.venv) $ docker build -t trueseeing .
