Cross-Site Scripting (XSS) Training Course.

The ultimate XSS training course – how to find, exploit, fix and prevent XSS vulnerabilities.

What is XSS?


Cross-Site Scripting, or XSS, is a security vulnerability in web applications that allows criminal hackers to inject harmful code directly inside web pages. This can result in a massive data breach, as seen in 2018 when the private data (including payment information) of 380,000 British Airways customers was stolen by attackers.

XSS Training Value


BOTTOM LINE: Fixing XSS vulnerabilities costs you more than the full price of this course.

MAKING THE CASE

A single XSS vulnerability report is often awarded over $1,000, growing with severity and impact. For instance, Google awards $7,500 and Yahoo has paid $10,000 for a single XSS vulnerability report.

Next comes the total cost of the vulnerability's lifecycle:

  1. Receive report
  2. Validate issue
  3. Create ticket for developer
  4. Setup development environment
  5. Find flaw in code
  6. Write fix
  7. Pass QA tests
  8. Release patch
  9. Verify fix with researcher (repeat if not fixed)
  10. Issue reward
  11. Coordinate disclosure details

To make matters worse, the cost of an XSS vulnerability grows exponentially when its exploited and causes damages with legal consequences, ruined brand reputation and loss of customers.
