Viewing requests sent by Burp extensions using Logger - Port Swigger

Summary: PortSwigger's tutorial shows how to use the Burp Logger tab to view requests generated or modified by Burp extensions, which do not appear in the HTTP history tab because that tab only records traffic from a browser proxied through Burp. Using the ActiveScan++ extension against the deliberately vulnerable portswigger-labs.net domain as a demonstration, it walks through filtering the Logger by the Scanner and Extensions tools and notes that requests an extension generates from scratch are listed under Extensions while requests it merely modifies stay under the original tool.

Bottom line: Extension traffic that never reaches HTTP history is invisible to anyone reviewing only that tab, so a scan run by an extension can send requests an analyst never sees unless they know to filter the Logger by tool.
