Dynamic Analysis

dynamic_analysis -- Code used for running our dynamic analysis.

Usage

First, configure the parameters in the 'external_storage_multi_device.py' Python file, and python external_storage_multi_device.py -d <device serial number> -n <instance number>

• Required parameters

-d device serial number # used for multi devices testing (acquired by "adb devices")
-n instance number # test instance numbers that can be set arbitrarily

Then, parse the output log python log_parsing.py -f <log_file> -o <output_path>

• Required parameters

-f log_file # path to the log file
-o output_path

Candidate Attributing

candidate_attributing -- Code used in our candidate attributing step.

Usage

Before conducting the candidate attributing, please install and start Frida on the test device. Configure the parameters in the 'candidate_attributing.py' Python file, and python candidate_attributing.py -a <apk file> -p <package name> -f <target file> -m <mode>

• Required parameters

-a apk file # path to the apk files to be tested
-p package name # package name of tested file
-f target file # file name that you want to attribute
-m mode # attributing mode (java or native)
