Streaming at [https://youtu.be/wa\_T8vAv9kg](https://youtu.be/wa_T8vAv9kg) Join us at [r/BSidesSF](https://reddit.com/r/BSidesSF) on Reddit for live AMA style Q&A (2020) Docker provides a convenient --privileged flag to create "privileged containers" but what does it actually do? In this talk, we will explain the internals of how docker provides isolation, and what happens when these security features are disabled. Spoiler alert: trivial container escapes.
