How Burp AT helped expose whistleblower reports via a critical vulnerability that was overlooked for years

Summary: During a four-plus-one pentest engagement, security analyst Ray Huygen used Burp AT to analyze a 66,000-line minified JavaScript bundle that he could not justify reviewing manually, and the tool found that whistleblower reports were protected only by a six-digit alphanumeric code. Huygen then had Burp AT run an Intruder attack that bruteforced the codes and exfiltrated the confidential reports, exposing a vulnerability that had been present for some time and missed in previous security assessments.

Bottom line: Confidential whistleblower reports were guarded by nothing more than a six-digit alphanumeric code, and the flaw survived prior pentests because no one could responsibly spend the time to find it - a malicious actor with the same patience could have reached those reports first.
