  Introduction to BugBounty & Web Exploit Hunting Bug Bounty Programmes Organisations offer rewards to ethical hackers for discovering and reporting vulnerabilities in their systems. This proactive approach significantly enhances security for real-world applications, often providing financial rewards, company merchandise, or recognition in a "Hall of Fame." Web Exploit Hunting This involves systematically identifying and exploiting weaknesses within web applications. It encompasses reconnaissance, thorough testing, and precise reporting. Ethical hackers play a crucial role in safeguarding digital assets before malicious actors can exploit them.

  The Crucial Roleof Cybersecurity The digital landscape faces an increasing threat from cyber-attacks, data breaches, and ransomware. Poorly secured web systems frequently expose sensitive information, making robust cybersecurity paramount. Organisations must fortify: • Login systems, ensuring secure authentication. • Databases, protecting sensitive data from unauthorised access. • APIs, securing communication pathways between systems. • Web servers, safeguarding the foundational infrastructure. Ethical hackers are indispensable in mitigating these risks, thereby protecting both users and businesses from devastating cyber threats.

  Essential Tools forWeb Exploit Hunting Each tool serves a specific purpose, aiding in reconnaissance, testing, exploitation, or reporting during the vulnerability discovery process. Burp Suite Intercepting, scanning, and manipulating web requests and responses. OWASP ZAP Automated vulnerability scanning for web applications. Nmap Network scanning and service detection for host discovery. Gobuster / Dirb Directory and file enumeration for hidden paths. Postman API testing, including request building and response analysis. Browser DevTools Client-side debugging and inspecting web elements. Kali Linux A complete operating system designed for penetration testing.

  OWASP Top 10:Critical Web Risks The OWASP Top 10 serves as a global standard for web application security, highlighting the most prevalent threats. A01Broken Access Control Flaws leading to unauthorised access to data or functionality. A02CryptographicFailures Weak or absent encryption exposing sensitive information. A03Injection Attacks like SQL, Command, or LDAP injection. A05Security Misconfiguration Vulnerabilities due to default settings or open ports. A07Authentication Failures Weak login mechanisms that are easily bypassed. A10SSRF Server-Side Request Forgery forcing the server to access internal resources.
• 7.
  Major Vulnerabilities Explored 1 SQLInjection(SQLi) Injecting malicious queries into database statements to retrieve or manipulate data. 2 Cross-SiteScripting (XSS) Injecting malicious scripts into web pages viewed by other users. 3 Cross-SiteRequest Forgery (CSRF) Tricking authenticated users into performing unwanted actions. 4 InsecureDirect Object References (IDOR) Accessing another user’ s data or resources by tampering with parameters. 5 FileUpload Vulnerabilities Uploading malicious scripts or files that can compromise the server. 6 Directory Traversal Accessing restricted files and directories outside the web root. 7 API Vulnerabilities Weak authentication, exposed sensitive endpoints, or improper input validation in APIs.
• 8.
  Practical Tasks Performed •Reconnaissance: Executed subdomain scanning and WHOIS lookups to gather target information. • Directory Discovery: Utilised tools like Gobuster and Dirb to uncover hidden directories and files. • Parameter Tampering: Modified request parameters to bypass security checks and access unauthorised data. • Authentication Testing: Probed for weak passwords, session management flaws, and other authentication vulnerabilities. • API Testing: Identified broken tokens and insecure endpoints within API structures. • Proof-of-Concept (PoC) Creation: Developed XSS and SQL payloads to demonstrate vulnerability exploitability. • Reporting: Crafted detailed bug reports, outlining impact, severity, and recommendations.
