So that's linking to a Forbes article that's paraphrasing this study from 2012: https://users.ece.cmu.edu/~tdumitra/public_documents/bilge12...

It doesn't support your assertion but it's still interesting 2008-2010 data from an antivirus vendor. It's talking about about how long some vulnerabilities were exploited by malware before getting disclosed, use in targeted attacks, and so on.

The study says that most vulnerabilities were being exploited before being disclosed.

[fulafel]

I don't think it says that about the set of all vulnerabilities (IOW - citation needed!).

It does say "In this paper, we consider only exploits that have been used in real-world attacks before the corresponding vulnerabilities were disclosed" so it's unsurprising that in their dataset this is the case :)

Yeap, you're right, I misread. Here is a quote from the paper: "15% of these exploits were created before the disclosure of the corresponding vulnerability." So there's a lower bound.
