I need a seasoned ethical hacker to run a full black-box penetration test against my own website. You will have no prior credentials or internal access; your job is to probe the public-facing application exactly as an external attacker would. Primary focus areas • SQL injection • Cross-site scripting (XSS) • Broken authentication I can supply formal, written authorization before any testing begins, ensuring everything is 100 % legal and above board. Please follow recognised methodologies such as OWASP Top 10, using tools you are comfortable with—Burp Suite, OWASP ZAP, Kali, or similar—combined with manual verification. Deliverables I expect • Executive summary outlining overall risk posture • Detailed technical report for each finding (steps to reproduce, affected URLs/parameters, severity, and remediation advice) • Proof-of-concept screenshots or payloads where applicable • Retest after fixes (optional but preferred) Kindly outline your approach, estimated timeline, and any relevant certifications (OSCP, CEH, etc.) when you respond.

I noticed you specifically need a black-box penetration test focused on SQL injection and XSS to secure your public-facing application. I can approach this exactly like an external attacker would. My process follows the OWASP Top 10 framework to ensure we don't miss any critical gaps in your authentication or data handling. I've spent years breaking and fixing web apps to help teams avoid the risk of a real breach. My security workflow involves: - Initial reconnaissance to map your attack surface. - Deep manual probing using Burp Suite and Kali. - Detailed reports with reproduction steps and payloads. - Clear remediation advice for your dev team. I focus on providing proof-of-concept evidence for every finding so there's no guesswork.

Hi there, I will execute a full black-box penetration test against your website — covering SQL injection, XSS, and broken authentication — and deliver a detailed report with severity ratings, reproduction steps, and remediation guidance for each finding. My approach: reconnaissance and fingerprinting first, then automated scanning with Burp Suite Professional paired with manual testing to eliminate false positives and catch logic flaws automated tools miss. For authentication testing, I will go beyond default credential checks — session fixation, token entropy analysis, and password reset flow abuse are areas where real vulnerabilities often hide. Questions: 1) Is the target a single domain, or are subdomains and API endpoints also in scope? 2) Do you need testing restricted to specific hours to avoid production impact? Looking forward to potentially working together. Thanks, Kamran

Hi - Elias here from Miami. The core challenge in performing an effective black-box penetration test is to simulate real-world attack scenarios without prior knowledge of the system's architecture. This often leads to oversight of critical vulnerabilities that could be exploited in production environments. Common pitfalls include inadequate coverage of edge cases, which can result in false security assurances. Additionally, a lack of comprehensive risk assessment can lead to overlooking systemic weaknesses, such as improper input validation or insecure API endpoints that are not immediately visible. I propose a structured approach: Input will consist of the application and its publicly accessible components. Processing will involve automated tools complemented by manual testing to identify vulnerabilities. The final Output will be a detailed report highlighting vulnerabilities, their potential impact, and actionable remediation steps. A critical decision early in the process is determining the scope of the test. This includes identifying which components are in-scope and ensuring we understand the business context to prioritize findings effectively. What security frameworks are you currently using, if any, to inform the testing process? Looking forward to your thoughts.

You’ve specified a black-box test against SQLi, XSS, and broken authentication—three high-impact vectors I target routinely using OWASP Top 10 as the baseline. I’ll combine automated scanning with manual verification to avoid false positives. Burp Suite Pro and OWASP ZAP will handle initial reconnaissance and vulnerability detection, while Kali Linux tools (sqlmap, XSStrike) and custom Python scripts validate findings. Each exploit path will be documented with curl commands or screenshots to ensure reproducibility. The report will split into an executive summary for stakeholders and a technical deep dive with remediation steps tied to OWASP’s mitigation cheat sheets. For retesting after fixes, I’ll reuse the same payloads and add regression checks for newly introduced vulnerabilities. All testing follows a strict “no data exfiltration” rule—proofs of concept stop at confirmation of access. I’ll deliver the full report and findings in 7 days. The €650 figure covers the scope as written; we’ll refine the number once we walk through the target’s architecture and any out-of-scope subdomains. A 15-minute call will clarify open points like testing windows or CI/CD hooks for retesting.
