Ethical Hack: Trading App Audit

@creatixclick

I'm Constantin, a seasoned Certified Ethical Hacker with deep expertise in network security and penetration testing. Over the past 7+ years, I've honed my skills in breaching systems legally, whether it be web apps, APIs, cloud infrastructure or internal networks. My focus isn't on merely ticking checkboxes but on thinking like an attacker, which has helped me find critical zero-days before they cause harm. One of my key strengths is translating complex findings into clear, actionable insights that will help you close any security gaps immediately. My clients rely on me to deliver concise reports that rank each finding by risk, reproduce the steps taken and provide actionable recommendations. I can provide this same value for your paper-trading websites and companion mobile apps. My qualifications speak volumes about my capabilities: CEH, OSCP, CISSP, PNPT, eWPT - an extensive array of certifications in the field that have prepared me to handle the toughest break-ins. You needn't worry about tooling either - I'm proficient with popular tools like Burp Suite, OWASP ZAP, Kali Linux and more and even have experience with custom scripts if need be. My commitment is to intensively test your system to detect any vulnerabilities and furnish thorough results to fortify your applications better than ever.

Hello, I am a Cyber Security & Digital Forensics professional with 9+ years of experience in Penetration Testing, Vulnerability Assessment, API Security, Mobile Application Security, and Digital Investigations. I have performed black-box, grey-box, and authenticated security assessments for web applications, mobile apps (Android/iOS), APIs, cloud environments, and enterprise infrastructures. For your paper-trading platforms, I can conduct a comprehensive penetration test covering reconnaissance, authentication controls, business logic flaws, privilege escalation, API security, session management, OWASP Top 10 vulnerabilities, and post-exploitation analysis. All findings will be validated manually, ranked by risk severity, and documented with proof-of-concept evidence, exploitation steps, impact assessment, and detailed remediation guidance. Deliverables include a professional penetration testing report, executive summary, technical findings, CVSS-based risk ratings, and developer-friendly mitigation recommendations. I am available to start immediately and can provide a thorough, industry-standard assessment within your required timeline. Best Regards, Kajal Majhi Cyber Security & Digital Forensics Specialist

Hello, I am a Cybersecurity Analyst and Penetration Tester with experience in Web Application Security, API Security Testing, Vulnerability Assessment, and Incident Response. I can perform a comprehensive security assessment of your paper-trading websites and mobile applications to identify vulnerabilities before deployment. My approach combines manual testing and industry-standard methodologies to uncover issues that automated scanners often miss. The assessment will cover: • Authentication and authorization testing • Session management review • API security testing • Business logic vulnerabilities • Privilege escalation checks • Input validation and injection testing • Sensitive data exposure review • OWASP Top 10 vulnerabilities • Mobile and web application security testing I use tools such as Burp Suite, OWASP ZAP, Nmap, Wireshark, Postman, Kali Linux, SQLMap, and custom Python scripts where appropriate. Deliverables include a detailed penetration testing report with risk-ranked findings, proof-of-concept evidence, reproduction steps, impact assessment, and practical remediation recommendations. I provide regular progress updates and can begin immediately. Before starting, I would appreciate clarification regarding the number of applications, APIs, user roles, and environments included in scope. I look forward to helping strengthen the security of your platform. Thank you.

Your paper-trading web + mobile apps need a structured pentest with risk-ranked findings — exactly what we can deliver as a team that builds and breaks web/mobile stacks daily. We'll run recon, exploitation, privilege escalation and post-exploitation across your web app and mobile APIs, using Burp Suite, OWASP ZAP, and custom scripts. Deliverable: a clear report your devs can act on immediately. Ping me to discuss scope and timeline.

Hi. I approach a web and mobile app the way an attacker would: map the surface, find where the trust assumptions break, and prove the impact rather than just flag a scanner warning. A full-scale test of your paper-trading sites and companion apps, with a clean report your developers can act on, is the kind of engagement I'm set up for. From the brief you want real reconnaissance, exploitation, privilege escalation and post-exploitation, then a concise report that ranks each finding by risk, reproduces the steps and gives fixes you can hand straight to your devs. I'd run it methodically, OWASP-style, across auth and session handling, access control and IDOR between accounts, and the trading and order flows where business-logic abuse usually hides (price and quantity tampering, race conditions on order placement, balance manipulation), plus the API layer behind the apps and the mobile clients for hardcoded secrets and insecure storage. Burp Suite and ZAP for the web and API work, Kali and custom scripts where it needs them. Everything against the production-like credentials you provide, scoped and responsible, each finding evidenced so it holds up rather than hand-waved. What you get is a prioritised report that shows how each gap was reached and exactly how to close it, written for your developers to action straight away. I can start on reconnaissance as soon as you share the scope and credentials.
