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

$ pip3 install trueseeing
$ trueseeing --bootstrap

Usage

The following command line is sufficient to scan a APK (target.apk), yielding findings listed in stderr:

$ trueseeing /path/to/target.apk

To generate a report in HTML format:

$ trueseeing -o report.html /path/to/target.apk
$ trueseeing --format=html -o report.html /path/to/target.apk

To generate a report in JSON format:

$ trueseeing --format=json -o report.json /path/to/target.apk

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

$ trueseeing -o - /path/to/target.apk > report.html
$ trueseeing --format=html -o - /path/to/target.apk > report.html
$ trueseeing --format=json -o - /path/to/target.apk > report.json

To fix (not all) problems it catches:

$ trueseeing --patch-all /path/to/target.apk
