Best of the Worst: Misadventures in Bug Disclosure
02-23, 19:30–20:15 (US/Central), Bootloader 📍Under The Oaks

This talk looks at some of the best of the worst examples of disclosing bugs to vendors. We'll go behind the scenes to show the sometimes gory details and laughable farces of bug disclosure. Finally, we'll offer some advice to those who may be on the receiving end of disclosure to help them ensure they don't end up in version 2.0 of this talk.


Founded by TippingPoint in 2005, the Zero Day Initiative (ZDI) program rewards security researchers for responsibly disclosing vulnerabilities. Since that time, the ZDI has grown to be the world's largest vendor-agnostic bug bounty program. Being vendor agnostic means we purchase bug reports from independent security researchers around the world in Microsoft applications, Adobe, Cisco, Apple, IBM, Dell, Trend Micro, SCADA systems, etc... We don't buy every bug report submitted, but we buy a lot of bugs. Of course, this means we disclose a lot of bugs. And not every disclosure goes according to plan.

This talk looks at some of the best of the worst examples of disclosing bugs to vendors. Disclosing bugs can get contentious. It can also be confusing when a vendor doesn't have a mature response process. Some reports are frustrating. Some reports are comical. And some are absolutely wild. All of them resulted in face palms at multiple levels. We'll go behind the scenes to show the sometimes gory details and laughable farces of bug disclosure. Finally, we'll offer some advice to those who may be on the receiving end of disclosure to help them ensure they don't end up in version 2.0 of this talk. Finding, disclosing, and fixing bugs are three different processes, and none of those processes are inconsequential. Here at the ZDI, we try to improve all three areas wherever we can.
