How to find the right Akamai BMP Version

BAPKA: A Detailed Overview

BAPKA (Akamai BMP APK Analyzer) is a specialized tool designed to detect the version of Akamai Bot Manager Premier (BMP) used in Android APK files.

Step-by-Step Guide to Using BAPKA

1. Install Prerequisites:

   • Before using BAPKA, you need two primary tools: apktool and Python 3.
   • apktool is used for reverse engineering Android APK files. You can download and install it from apktool's website.
   • Ensure you have Python 3 installed on your system. You can download it from Python's official website.

2. Download BAPKA:

   • Clone or download the BAPKA repository from its GitHub page.
     Or get from here:

#!/usr/bin/env python3
import argparse
import glob
import os
import subprocess
import re

TMPDIR = "/tmp/bapka"


def apktool_decompile(file):
    print("APKTOOL: Starting to decompile")
    outdir = os.path.join(TMPDIR, "out")
    try:
        subprocess.run(
            ["apktool", "d", file, "-b", "-f", "-r", "-o", outdir], check=True
        )
    except Exception as e:
        print(f"APKTOOL: Failed to decompile the apk: {e}")
        exit(1)
    print("APKTOOL: Decompiled successfully")
    return outdir


def grep(root_dir, pattern) -> None | re.Match:
    pattern = re.compile(pattern)
    for path in glob.iglob("**/*.smali", root_dir=root_dir, recursive=True):
        abspath = os.path.join(root_dir, path)
        with open(abspath, "r") as f:
            for line in f:
                result = re.search(pattern, line)
                if result is not None:
                    return result

    return None

def get_bmp_version(dir):
    result = grep(dir, "BMPSDK/(.+) \\(")
    if result is None:
        print("ERROR:")
        exit(1)
    return result.groups()[0]



if __name__ == "__main__":
    parser = argparse.ArgumentParser()
    parser.add_argument("filename", help=".apk file to analyze")
    args = parser.parse_args()
    config = vars(args)

    decompiled_dir = apktool_decompile(config["filename"])
    bmp_version = get_bmp_version(decompiled_dir)
    print("Akamai BMP found!")
    print(f"BMP Version: {bmp_version}")

3. Prepare the APK File:

   • Obtain the APK file you want to analyze. Ensure you have the correct path to this file on your system.

4. Run BAPKA:

   • Open a terminal or command prompt.
   • Navigate to the directory where you downloaded BAPKA.
   • Run the following command:

     ./bapka <path-to-apk.apk>

     Replace <path-to-apk.apk> with the actual path to your APK file.

5. Analyze the Output:

   • After running the command, BAPKA will analyze the APK file and output the version of Akamai BMP used in it.
   • This information is crucial for understanding the bot management capabilities integrated into the app.

6. Contribute to the Project:

   • If you have information about other apps using Akamai BMP or newer versions, you can contribute to the BAPKA project by submitting a Pull Request on GitHub.
