Mitigating Parameter Tampering: Practical Insights and Solutions

Delve into the world of parameter tampering with our in-depth presentation. This project highlights the risks associated with manipulating request parameters and provides actionable strategies for detection and prevention. Through a series of practical labs and case studies, we demonstrate how parameter tampering can undermine web application security and explore effective measures to safeguard against it. for more information visit: https://bostoninstituteofanalytics.org/cyber-security-and-ethical-hacking/

3. Parameter Tampering   Parameter tampering is a type of web-based  cyber attack  in which certain parameters in a  URL  are changed without a user's authorization. In some cases, the data entered by a user into a form field of a webpage may also be modified -- again, without the user's authorization. The attack may point the  browser  to a link, page or site that the user did not intend to access.

5. TYPES OF PARAMETER TEMPERING

6. 1. Cookie Manipulation Think of cookies as the digital crumbs that track your online journey. While they generally serve for good purposes, Attackers can easily alter cookie contents and send them back to the server, a process known as Cookie Manipulation.

7. 2. Form Fields Manipulation Forms, are not immune to manipulation. Attacker exploit this vulnerability by tweaking the information transmitted to the server via these forms..

8. 3. URL Manipulation URLs play a crucial role in data transmission, but they can be exploited by attackers.    An attacker can intercept this URL and manipulate the debit amount, potentially causing financial chaos by altering the "1" to a much larger value.

9. 4. HTTP Headers Manipulation: HTTP headers, accompany every request and carry essential metadata. Among these, the referrer header show the source of a request. Attackers, however, can manipulate this header to trick Server into thinking a request originates from a trusted source. 

10. TOOLS

11. Burp Suite It is developed by the company named Portswigger , which is also the alias of its founder Dafydd Stuttard .  Burp or Burp Suite is a set of tools used for penetration testing of web applications. It is the most popular tool among professional web app security researchers and bug bounty hunters. Its ease of use makes it a more suitable choice over free alternatives like OWASP ZAP.
