ALEAPP - Android Logs Events And Protobuf Parser

From the department of unimaginative names comes ALEAPP, the sister script to iLEAPP. For additional information on iLEAPP go here.

ALEAPP will aggregate all my previous Android parsing scripts as well as be the framework for future script development. Previous users of iLEAPP will recognize the same interface and workflow present in ALEAPP. The script can parse logical file systems, tar and zip extractions as well as providing reports in html and csv formats.

ALEAPP can be downloaded from:

GUI interface
This first release only parses events and accounts from the Wellbeing Android database. I can't thank enough Josh Hickman for sharing his research on the Wellbeing database and allowing me to use it to make the first ALEAPP artifacts. His research is a must read if you do Android digital forensics and can be found here:

The next artifact to be supported will be UsageStats events both in XML and protobuf formats. For details on this artifact go here and here. The standalone script that parses UsageStats can be found here. ALEAPP will absorb that functionality. Many thanks to Yogesh Khatri for his UsageStats research and coding.

The prerequisites for ALEAPP are:

  • Python 3.7.4 and above
  • pip install six
  • pip install PySimpleGUI
The next screenshots illustrate the Wellbeing artifacts output.

The Wellbeing Account report normalizes a protobuf file for account information. The data is shown in both parsed and unparsed formats.

Account data
The Wellbeing Events report has tons of useful data. Josh Hickman's post has all the details. Great investigative data source.
