A "private 0day exploit" (the case I was concerned with) would be where someone develops an exploit, but does not deploy or publish it, holding it in reserve to attack others at the time of their choosing. Presumably if such a person wanted to keep it for very long, they would have to base it on a vulnerability that they themselves discovered, and did not publish. I continue to dismiss the requirement that an 0day be found maliciously exploiting machines, because that requires inferring intent. IMHO, a POC exploit first posted to Bugtraq ahead of the patch counts as an 0day exploit, unless it has been so thoroughly obfuscated that the "proof" part of "proof of concept" is itself BS.
In the case of that "private zero day exploit", then, nobody will ever know about it except the person that has it waiting in reserve -- and if someone else discovers and patches the vulnerability before the exploit is ever used, it never becomes a "public" zero day exploit. In other words, you can always posit that there's sort of a Heisenbergian state of potential private zero day exploitedness, but in real, practical terms there's no zero day anything unless it's public. The moment you have an opportunity to measure it, the waveforms collapse. -- CCD CopyWrite Chad Perrin [ http://ccd.apotheon.org ] Amazon.com interview candidate: "When C++ is your hammer, everything starts to look like your thumb." _______________________________________________ Full-Disclosure - We believe in it.
