Penetration Testing, or “pentesting” for short, is a valuable service for businesses and organizations of all sizes. It involves trying to access a system, website, or service illegally in order to expose any vulnerabilities that hackers can exploit. This allows IT departments and the people that protect the organization’s data to see those security issues before anyone malicious does. A Penetration Tester can help an organization keep their systems securely running by tackling any issues they discover while testing their systems.

I need an experienced ethical hacker to assess the security of my production web application. The platform handles login credentials—users sign in with their mobile number and password—so I want to be absolutely certain this flow cannot be abused. Scope • Run a full penetration test coupled with an automated and manual vulnerability scan. • Focus especially on authentication, session management, and any area where those credentials travel or are stored. Deliverables - A clear, step-by-step report detailing every finding, severity rating, and proof-of-concept where exploitation is possible. - Practical remediation advice I can hand straight to my development team. - A concise executive summary of overall risk. All testing must respect live-traffic uptime, ...

I have an existing web application that must be pulled apart and inspected from every angle so we can see exactly where it breaks. The assignment centres on software-level reverse engineering, with the single overriding goal of identifying security vulnerabilities in the code base and its runtime behaviour. Once we confirm your availability I will provide the full application bundle, test server images and any credentials you might need. Your analysis should combine static code inspection with dynamic testing: think Burp Suite for traffic interception, Wireshark or similar packet capture, plus any de-obfuscation or disassembly tools (IDA Pro, Ghidra, etc.) that help you drill into compiled assets. Please follow OWASP guidelines so results are mapped to familiar risk categories. Deliverab...
I will hand you a Python code-base that already runs inside a Kali Linux environment. Your sole focus is to uncover and remediate security vulnerabilities. To do that, please rely on the exact tool-set I use internally—Bandit for static checks, Pytest for security-oriented unit tests, and OWASP ZAP for dynamic assessment of any exposed endpoints. Performance or feature refactoring is out of scope; I only care about hardening the code. After the fixes, I need a formal report (2300–2500 words, academic tone) that captures: • the initial risk profile revealed by Bandit, ZAP and targeted Pytest failures • a clear walk-through of each exploit or weakness you reproduced, including proof-of-concept snippets or ZAP evidence • the remediation steps you applied, refe...

Building a Rust-based security research tool that correlates multiple CVEs across different classes — privilege escalation, information disclosure, misconfigurations in email/SMS APIs, SMTP relays, and databases. The goal: simulate real-world attack chains that lead to exposure of sensitive data (API keys, database credentials, communication logs) so defenders can identify weak links. Looking for 2–3 motivated Rust developers to collaborate. You should know: · Rust (systems-level) · CVE analysis (any class — info leak, auth bypass, misconfig) · Working with APIs, databases, or network protocols What we're building: A detection engine that chains unrelated CVEs (e.g., an info leak + a weak SMTP config + a database misconfig) to map full expos...
I need a certified cybersecurity professional to determine whether my personal Android phone has been subjected to unauthorized access and to help me regain full, lawful control of every component that may have been touched. The device is the only confirmed target right now; however, if traces lead to email or social channels I will widen the scope with you. Your investigation must be forensically sound so that any evidence you uncover can stand up to scrutiny should I decide to take legal action. I am expecting a hands-on approach that covers log collection, malware/spyware scanning, vulnerability mapping, and clear recommendations on how to close every gap you find. Where recovery steps are needed—password resets, two-factor reconfiguration, data restoration—I want you ...
