I’m trying to figure out how 0day ebooks are sourced. To be clear, I’m not talking about release groups like bitbook or libricide but on ddl forums I frequent. Just as an example, this book on amazon has a publication date of March 7th and it’s already available on places like avax. I looked into other sources like irc and nothing. They can’t be buying out of pocket right?
That could be part of it but I’m not sure it comes close for most ebooks. A lot of these books are professionally typeset and laid out pdfs, not sloppy calibre conversion pdfs. I don’t think Amazon sells in pdf. As far as bounty forums, I just looked at one site over the last three days. It averaged 365 books per day, 199 per day with 2023 publication dates. That seems like a lot of successful bounties!
