WAF Cookie Fetcher
Summary: PortSwigger lists a Burp extension, WAF Cookie Fetcher, that lets testers register cookie-related session handling actions so Burp's cookie jar picks up values set by a WAF or bot defense system through client-side JavaScript. The extension generates a PhantomJS script and calls the PhantomJS binary directly to load the page and return the cookie, which tests showed was quicker than using Selenium, and it also supports removing named cookies or emptying the jar.
Why it matters: Without the updated cookie value, Burp's requests get blocked, which the extension's author says makes it very difficult to use the Scanner and Intruder against sites running these bot defenses.
