I am looking for an experienced reverse engineer or mobile security specialist to help analyze the network communication of an Android application. The application currently implements SSL certificate pinning, which prevents traffic inspection using standard interception tools (such as proxies). Because of this, I cannot capture the login requests and related API communication. Project Goals: Perform reverse engineering of the Android APK. Identify and bypass the SSL pinning protection implemented in the app. Enable traffic inspection so the login requests can be captured and analyzed. Document the login request structure and related API endpoints. Help replicate the login request programmatically using either: Node.js, or Python The final goal is to understand how the login API works and reproduce the request flow externally in order to determine whether a user is recognized by the system (e.g., identifying existing customers vs non-customers). Additional Information: The application does not detect root when using APatch. The main challenge is bypassing the SSL pinning mechanism to inspect the login traffic. Experience with tools such as Frida, Objection, Burp Suite, HTTP Toolkit, APKTool, JADX, or similar reverse engineering tools is highly preferred. Familiarity with Android networking libraries (e.g., OkHttp, TrustManager, CertificatePinner) is a plus. Deliverables: Method used to bypass SSL pinning. Captured login request and relevant API endpoints. Working example script in Node.js or Python that replicates the login request. Please apply only if you have prior experience with Android reverse engineering and SSL pinning bypass.

Hello, I understand you want to analyze an Android app to capture login requests, map the API endpoints, and reproduce the login flow with Node.js or Python. I will start with a careful, ethical reverse engineering approach: map the APK’s network path, locate the SSL pinning implementation (OkHttp/TrustManager/CertificatePinner), and identify how to safely bypass it for traffic inspection using a controlled test environment. I will document the exact method used to bypass SSL pinning, set up a test proxy to capture traffic, and extract the login request structure and endpoints. Then I will deliver a working script in Node.js or Python that reproduces the login request, with clear steps to validate the flow against the server. The work will include a concise report on findings and a sample test script you can run locally. What is the preferred timeline for delivering the pinning bypass method, captured login traffic, and the final reproducible script? Best regards,

Hello! I have gone through with your requirement and understand that you want to analyze the network communication of an Android application by reverse engineering the APK and identifying how the login API works so the request flow can be reproduced programmatically. I have experience working with Android application analysis and can review the APK structure to understand the networking implementation, including libraries such as OkHttp and certificate validation layers. The process would involve inspecting the compiled code, identifying where certificate validation and pinning logic are implemented, and analyzing the request structure used for authentication. Once the request flow is understood, I can document the API endpoints, request headers, payload structure, and authentication flow. Based on this analysis, I can create a reproducible script in Node.js or Python that demonstrates how the login request is constructed and sent programmatically. The final deliverables will include documentation of the request structure, identified API endpoints, and an example script that replicates the login request for testing and analysis purposes. I would be happy to review the APK and discuss the analysis approach in more detail. Best regards, Jasmin

Hello, I carefully reviewed your requirement for analyzing the network communication of the Android application and I understand that the main challenge is bypassing the SSL certificate pinning to inspect login traffic and capture the related API requests. The task involves reverse engineering the APK, identifying the pinning implementation within the networking layer such as OkHttp or CertificatePinner, applying a reliable bypass method using tools like Frida, Objection or dynamic instrumentation, and enabling proper interception through tools like Burp Suite or HTTP Toolkit. With over 10+ years of experience in mobile application analysis, reverse engineering, Android networking, and API debugging, I can analyze the APK, implement a working SSL pinning bypass, capture the login request structure and endpoints, and then reproduce the request flow programmatically using Node.js or Python. I will also document the method used, provide a clear explanation of the login API behavior, and deliver a working script that replicates the request reliably for further testing or integration. I WILL PROVIDE 2 YEAR FREE ONGOING SUPPORT AND COMPLETE SOURCE CODE. WE WILL WORK WITH AGILE METHODOLOGY AND WILL GIVE YOU ASSISTANCE FROM ZERO TO PUBLISHING ON STORES. I eagerly await your positive response. Thanks.

Hi, I understand you need assistance analyzing the network communication of an Android application that currently uses SSL certificate pinning, preventing traffic inspection through standard proxy tools. The goal is to study the login flow, identify the related API endpoints, and reproduce the login request externally using either Node.js or Python. My approach would begin with static and dynamic analysis of the APK to understand the networking implementation and identify the certificate pinning logic. After enabling traffic inspection in a controlled environment, I will capture the authentication requests and map the request structure, headers, and payload format. Based on that analysis I will create a small script that reproduces the login request flow programmatically. Before delivery I will verify that the captured requests are accurate, confirm the replicated request works reliably, and provide clear documentation describing the request format and endpoints so the process can be reproduced easily. Best, Justin
