Re: Using 0days as part of pen-test?

[Javier Reyna Padilla <jreyna () onlinet com mx>]

Well I think that if you can identify a 0day, and you are able to 
exploit, then you have a plus over a lot of just-framework-pentesters, 
not trying to talk bad about anybody. And the point is to probe the 
network is vulnerable. I think it is ok to exploit 0days, but ofcourse 
you will explain that in the final report, and then you might do 
whatever you want with your research.   Maybe, things will depend on the 
contract you sign with your customer about tecniques, procedures, and 
what kind of explotations you are allowed to test.

¡Saludos!
