@alamin500a

Hi, I'm an OSCP, CEH, and eJPT certified penetration tester with hands-on experience testing web applications following the OWASP Testing Guide, and I can start on your engagement right away. For this project, I'll focus on the three high-risk areas you mentioned: Authentication & Authorization: testing for broken access control, privilege escalation, session/token weaknesses Database Exposure: SQL injection, insecure queries, and misconfiguration checks Input Handling: XSS, command injection, and other input-based vulnerabilities I'll treat this as a real-world black/grey-box assessment using Burp Suite, OWASP ZAP, sqlmap, and manual exploitation techniques where needed — not just automated scans. My OSCP training especially helps in manually chaining vulnerabilities to demonstrate real business impact, not just surface-level findings. Deliverable: A detailed report with each vulnerability classified by severity (Critical/High/Medium/Low), proof-of-concept steps, and clear remediation recommendations — aligned with OWASP standards. I'm available to start as soon as you share the staging/live URLs and test credentials. Happy to hop on a quick call to discuss scope and timeline. Thanks, MD. AL-AMIN

@elluappsec

Hi, I'm an OSCP-certified penetration tester experienced in black/grey-box web application assessments and would like to take this on. My methodology aligns directly with the OWASP Testing Guide and your three priority zones: 1. Authentication & authorization — session management flaws, privilege escalation, broken access control (IDOR), JWT/token weaknesses, and logic flaws around your provided test accounts. 2. Database exposure — SQL injection (manual + sqlmap-assisted), insecure query construction, and misconfigurations that could leak or expose data. 3. Input validation — XSS (reflected/stored/DOM), command injection, SSRF, and related injection classes across all input surfaces on staging and live URLs. Tooling: Burp Suite Pro for manual testing and traffic analysis, OWASP ZAP for automated coverage, sqlmap for injection validation, plus custom scripts where needed. No source code required — I'll treat this as a genuine external engagement. Deliverable: a prioritized report (CVSS-scored) with technical detail, business impact, and clear remediation guidance for each finding, plus a short walkthrough call if useful. I'll respect the scope you define (staging/live URLs, provided accounts, API keys) and flag anything destructive before touching it. Ready to start as soon as access is shared.

@momrulhasan

Hello, I can conduct a controlled external penetration test of your network and server infrastructure within the agreed maintenance window. I hold practical cybersecurity certifications including CPTS, CRTA, C3SA, CAP, and CNSP, with hands-on experience in network enumeration, vulnerability assessment, exploitation, Active Directory security, and risk reporting. Before testing, I will provide a clear scope and rules-of-engagement plan. The assessment will include Nmap-based reconnaissance, vulnerability validation with Nessus/OpenVAS, careful manual exploitation, and evidence collection without unnecessary service disruption. You will receive: • Prioritized technical and executive-level findings • Business impact and actionable remediation guidance • A debrief session covering each major issue • One complimentary retest of resolved critical findings I will only test approved systems and will immediately report any issue that could affect availability. Could you confirm the number of public IP addresses and whether VPN access will be provided for the server segment? Best regards, Momrul Hasan
