I need a full grey-box security assessment covering both the Android and Web versions of my application, all of which run on AWS infrastructure. You will have complete source-code access, so please combine dynamic penetration testing with static code review to uncover anything a traditional black-box approach might miss. Key risk areas to probe: • Data breaches • Authentication flaws • Malware threats • Overall AppSec posture Your work should span OWASP Top 10 techniques, include cloud-specific checks for our AWS setup, and leverage industry-standard tooling such as Burp Suite, OWASP ZAP, MobSF, Metasploit, and relevant AWS security services. Deliverables I expect: 1. A brief test plan outlining scope, tooling, and timelines before you start. 2. A detailed vulnerability report that assigns severity (CVSS), shows clear reproduction steps with screenshots or PoCs, and offers actionable remediation advice. 3. A concise executive summary suitable for non-technical stakeholders. 4. One free round of re-testing after fixes, culminating in a final security attestation letter. Please outline your approach, estimated duration, and any prior experience with similar Android-plus-Web engagements on AWS. Cost is fixed from Bank Side between 15 to 20k

Grey-box with source on both sides changes the order I'd work in: static review of the Android app and the AWS-hosted web backend comes first, not parallel with the dynamic pass, so the pentest goes after what the code actually does instead of running a generic OWASP checklist against it blind. I'd also want IAM policies, S3 bucket ACLs and security group rules in scope on the AWS side, not just the app layer, account-level misconfig is easy to miss if the audit stays inside the code. I've paired static and dynamic like this on Node and Java backends before, cross-referencing source findings against live PoCs so the CVSS scores in the report tie to something reproducible, not just a scanner line item. M1: Recon, threat model, static source review of both apps. 21450 INR, 4 days. M2: Dynamic testing against OWASP Top 10 plus the AWS IAM, S3 and security group checks, PoC builds. 21500 INR, 5 days. M3: CVSS-scored report, executive summary, retest round, attestation letter. 22050 INR, 3 days. 65000 is priced off the brief as it stands, I'd firm it up once I know roughly how many endpoints and how much code there is, and how many AWS accounts sit behind this. How many environments does the AWS side actually span, one account or several?

Hello, I can perform the grey-box security assessment for your Android and Web applications hosted on AWS. My approach combines static code review using your source code access with dynamic penetration testing to uncover data breach risks, authentication flaws, and malware vectors. I will evaluate your system against the OWASP Top 10 for both web and mobile, conduct cloud-specific security checks on your AWS architecture, and utilize industry-standard tools like MobSF and Burp Suite alongside native cloud security services. You will receive a detailed report outlining identified vulnerabilities and remediation steps. 1) What is the timeline for completing this security assessment and delivering the final report? 2) Are there specific user roles or privilege levels we should focus on during the authentication and authorization testing?

Hi, I have worked on several web applications, mobile applications, AWS environments, authentication systems, and security-focused QA projects, including recent QA work on AI and production applications. ? The main challenge is finding security weaknesses that only become visible when source-code review, application testing, mobile analysis, and AWS configuration are examined together. ✅ In similar security projects, the core issue was that vulnerabilities could exist across authentication, APIs, client-side logic, backend code, mobile storage, and cloud configuration rather than in one layer. I approach this with grey-box testing using the available source code and staging environment, combining static review with controlled dynamic testing. ✅ I can provide the test plan before starting, followed by a detailed report with CVSS severity, affected components, reproduction steps, evidence, screenshots or safe PoCs, and actionable remediation guidance. With this kind of experience, I can contribute to identifying and documenting the real security risks across your Android, web, and AWS environments. Looking forward to discussing your security requirements with you. Best regards Michel

Hi, a grey box security assessment across your Android app, web app and AWS setup, with source access so we catch what black box testing alone would miss. What worries you most right now, auth flows or something specific in the AWS config? We'd run OWASP Top 10 testing with Burp Suite, ZAP, MobSF and Metasploit, map findings to CVSS with clear repro steps, then hand over a report plus a plain English summary for your stakeholders and a free retest once fixes land. Happy to start with the test plan as a first milestone so you can see the scope before we go deeper. Regards, Mariam

Grey-box with source in hand is the right call, because the findings that actually hurt on AWS usually live between the app and the account: an over-permissive IAM role, a bucket policy nobody revisited, secrets in an environment variable the code reads. Black-box rarely surfaces those. My background is web application penetration testing and security audits against OWASP Top 10 with CVSS-scored reports, plus a past role analyzing vulnerabilities in widely used open source Python packages, so static code review is familiar work. I also led a data team for five years running production pipelines on AWS, which is where the cloud checks come from. My pentest depth is on the web side, so for the Android app I'd focus on source review and the API it talks to rather than claim mobile tooling experience I don't have. One question before I draft the test plan: do the Android and web clients share one backend API, or are there separate services? That changes scope and duration. Thamer

Hello, I can perform a structured grey-box security assessment across your Android and Web applications, combining source-code review with controlled dynamic testing to identify vulnerabilities that black-box testing may miss. With 5+ years of security-focused web and application development experience, I can assess authentication, authorization, session management, input validation, data exposure, insecure APIs, storage and other OWASP Top 10 risks. For Android, I’ll review the application and backend attack surface using appropriate mobile security techniques and MobSF, while Burp Suite/ZAP can support controlled web/API testing. For the AWS environment, I’ll review relevant IAM permissions, exposed services, security groups, storage/configuration risks, logging and other cloud security controls within the agreed scope. Findings will be documented with CVSS severity, affected components, reproduction steps, evidence/screenshots where appropriate and practical remediation guidance. I’ll provide the test plan first, followed by the detailed technical report and executive summary. After fixes, I’ll perform one complimentary retest and provide the final security attestation based on the tested scope and results. Relevant security assessment examples can be shared where applicable. Best Regards, Shailender
