Certificate Transparency (CT) logs are a new and incredibly useful tool for bringing auditability and accountability to the public web certificate ecosystem. CT logs aim to provide a verifiable, append-only history of all publicly trusted certificates on the web. With browsers like Chrome now enforcing that certificates belong to CT logs, CT logging has become a vital part of the web's ecosystem.

But as with any new technology, it's our hacker duty to ask the question "How can this be misused?" We'll be providing a deep-dive into what CT logs are, how they work, and how we can take advantage of them for novel and nefarious purposes. We'll also explore if any bad actors have exploited our use cases in the wild. Most importantly, we'll be showing you why CT logs are the best new place to find pictures of cats on the internet.
