Android App Security Assessment

@kamran2012

This looks like a great fit, I will build the AI integration with proper model selection, prompt engineering, and output validation. The system will process inputs accurately and deliver structured results. I will set up a validation layer between the AI output and your application so uncertain or malformed responses get flagged before reaching the end user. Questions: 1) What AI model or provider do you prefer - OpenAI, Claude, or open-source? 2) What is the expected volume of requests per day? 3) Do you need the AI to work with your existing data or documents? Ready to start whenever you are. Kamran

Hi, I’m a freelance cybersecurity specialist with hands-on experience in mobile application penetration testing, including black-box assessments of production Android apps. I can simulate a real-world attacker by installing and testing your APK across physical devices and emulators, performing deep analysis of authentication flows, local storage, network traffic, exposed components, and business logic. My approach combines automated scanning with advanced manual testing using Frida, JADX, and runtime instrumentation to uncover issues that typical scans miss such as logic flaws, insecure API interactions, misconfigurations, and improper implementation of controls like Scoped Storage, TLS pinning, and Play Integrity. Deliverables will include: 1. Executive summary with risk-rated findings (Critical/High/Medium/Low) 2. Detailed technical breakdown with clear reproduction steps, screenshots/PoC, and remediation guidance 3. Re-test verification report after patches to ensure closure I follow structured methodologies aligned with OWASP Mobile Testing Guide and maintain strict legal and ethical boundaries. I can begin immediately and provide a clear timeline once I review the APK scope. Regards Kajal Majhi

Hi, As per my understanding: You need a comprehensive black-box security assessment of your production Android APK, simulating a real-world attacker without source code or credentials. The scope includes authentication flaws, insecure data storage, network vulnerabilities, component exposure, and business-logic weaknesses. You expect both automated and manual testing, reproducible findings, and a structured report with risk classification and retest validation. Implementation approach: Phase 1: Environment setup across physical devices and emulators (rooted/non-rooted scenarios). Static analysis using JADX/MobSF to review manifest, permissions, exported components, hardcoded secrets. Phase 2: Dynamic analysis using Burp Suite, Frida, and runtime instrumentation to test authentication bypass, token handling, TLS pinning, API abuse, and Play Integrity validation. Phase 3: Storage & logic review—SharedPreferences, databases, file storage, IPC exposure, deep links, intent hijacking, and rate-limiting checks. Phase 4: Exploitation validation with reproducible PoCs. Deliverables: executive summary (risk-tiered), detailed technical report with steps/screenshots, remediation guidance, and post-patch retest memo. A few quick questions: • Is this app publicly available or privately distributed? • Any third-party SDKs integrated? • Do you permit controlled MITM testing? • Target timeline for completion?

Hi, I’ve carefully read your requirement for a full black-box security assessment of your production Android app. With 5+ years in mobile development and experience working with secure APIs, authentication flows, TLS pinning, and Play Integrity implementations, I understand both the developer and attacker perspectives. For this engagement, I would approach testing in structured phases: APK static analysis (JADX, MobSF), dynamic testing (emulator + real devices), traffic interception (Burp Suite), runtime manipulation (Frida), and business-logic validation through controlled manual exploitation. Focus areas would include auth bypass risks, insecure data storage, exposed components, API misconfigurations, and certificate pinning resilience. Deliverables will include a clear executive summary (risk-tiered), detailed technical findings with reproduction steps/PoC, screenshots, and precise remediation guidance. After patching, I will conduct a re-test and provide closure validation. I can begin immediately and ensure findings are practical, reproducible, and aligned with modern Android security standards. Best regards, Vinod

@Venkatesan03

Hello, I have 5+ years of hands on experience in mobile application penetration testing, including production Android apps handling sensitive data. I approach this as a true black box assessment with no source code or prior access. I install the APK across real devices and emulators, then simulate a real world attacker focusing on authentication flows, token handling, local storage, IPC components, exported activities, deep links, and network communication. Testing combines manual exploitation with controlled automated analysis. I use tools such as MobSF for static review, Burp Suite for traffic interception and API abuse, Frida for runtime manipulation, and JADX for reverse engineering. I validate controls like Scoped Storage enforcement, TLS pinning, Play Integrity API checks, secure keystore usage, and resistance to tampering and reverse engineering. The goal is to uncover business logic flaws and misconfigurations that scanners alone miss. You will receive a concise report with an executive summary that ranks issues by severity, detailed technical write ups with reproduction steps and proof of concept evidence, and clear remediation guidance. After fixes, I perform structured retesting and provide a closure memo confirming resolution. I can begin immediately and align the engagement to your production constraints. Thank you

@BrainstackTech

Hello there, We bring 8 years of experience in application security testing and secure architecture design. Your black-box review covering auth, data storage, network calls, and component exposure with manual exploitation alongside automated scans is exactly where depth matters more than tooling alone. Our approach: custom Frida scripting to automate SSL pinning bypasses, Play Integrity checks, and Scoped Storage analysis, feeding structured reports beyond generic MobSF output. All traffic proxied through Burp Suite with custom Python extensions flagging business-logic flaws like broken object-level authorization or token replay that automated scans miss entirely. We'd use JADX for static analysis first to map the attack surface before manual exploitation, and script adb-based intent fuzzing for exported components — giving you reproducible PoC scripts to re-run after patching. Our government platform work — identity verification and benefits distribution for 25M+ citizens — required this exact rigor, pentesting our own APIs and auth flows before every release. Our core strength is backend and API security, not dedicated mobile pentesting, but we bridge that gap through automation-heavy custom tooling that delivers deeper results. Three phases over 18 days: recon and automated scanning (days 1-5), manual exploitation and business-logic testing (days 6-12), final report with executive summary plus re-test memo (days 13-18).

@Jafferi12

Bypassing TLS pinning and Play Integrity on a production app is exactly where basic scanners fail and real testers shine. Your plan for deep manual testing is completely right and I love this challenge. I will take your APK and tear it apart in my custom lab to hunt down authentication flaws and hidden data leaks. My workflow mixes manual business logic abuse with dynamic hooking using tools like Frida and Burp Suite to see everything the app tries to hide. I keep my exact bypass methods private right now so other bidders cannot copy my approach. You will get a crystal clear report with exact reproduction steps and screenshots. I will also make a simple developer fix guide document so your team can patch the code right away. This means you do not have to hire another freelancer just to understand and apply the fixes. Let us open a chat and get this audit started right now.
