I will stream in 8h about the basics of the PDF format, teaching how to make a basic PDF from scratch.
This is an easy-level introduction to the PDF [portable document format], aimed at all audiences: infosec, but also digipres, DFIR, and others.
This will not cover complex cases, polyglots, abuses or exploit.
That will come next but this stream is the start on the topic.
The stream will be recorded and available publicly.
