[MoBP] Search me

Summary: PortSwigger added a suite-wide search function to Burp Suite that lets users enter an expression and search request headers, response bodies, specific tools, or everywhere, with matches shown in a sortable table and a preview pane showing full requests and responses with highlighted hits. The post describes using it to test whether credit card numbers were masked after initial submission, and the search found a couple of obscure locations where the number was transmitted to the client within HTML source even though it was masked everywhere on-screen.

What you should know: The masking held on-screen but not in the HTML source, so a control that looks correct in the browser can still ship the full card number to the client - and only searching the raw responses surfaces it.
