Because life is not that easy, even if you are an example of goodess, stangre things can happend ... it's more or less like the spanish use to say "no creo en las bruxas, preo que las hai, las hai", something like 'i dont beleave in witches, but that they exist, they exist' ... Even being a presentation based on FW-1, most firewalls are vulnerable to the types of attacks demonstrated (explanation and source code are included): http://www.dataprotect.com/bh2000/ This is about the Black Hat Briefings 2000 presentation by Thomas Lopatic (Rhino9), John McDonald (Rhino9) and Dug Song (Monkey.org) Hope it helps somebody, [ ]'s bacano P.S.- Trivia: witch was the geek who traveled to Black Hat, with the box on the sit of the airplane? you got 3 choices ... =) --------------------------------------------- Esta mensagem foi enviada usando o WebPOP II. http://www.via-net-works.pt/email
