You can get this from the media server, along with a copy of the Music CD as an ISO (using torrent) if you want one, and any slides/presentation files from speakers we may have:

The Receipt for DEF CON 25: https://media.defcon.org/DEF%20CON%2...25-Receipt.pdf

For a list of DEF CON 25 files on the media server:

The media server also contains audio files for music CD in other formats:
