Where can I find literature on 0 day vulnerabilities?

Question

Information Security

I can't find any good postings on 0 day vulnerabilities. Tired of searching.

Answer 1

Dear "Enthusiast", 0-day, he is 0-day for that, that no one knows about him, except for the one who discovered and uses him. These vulnerabilities are sold for hundreds of thousands of dollars, who will give them to you on a silver platter just like that? Learn to look for them yourself.
