I, too, would love to get the details, but Peter is right here. The flaw he reported was in the PKI itself, not in the UI. If there were a bulletproof OS with perfect non-confusing UI, once the malware has a valid signature that traces to a valid certificate, it's the PKI that failed.
As for EV being as meaningless as ordinary certificates, that's the point Peter is making. Of course, neither of them certifies the qualities of the publisher that the end user cares about. That would be too expensive and open to liability (therefore, more expensive still). But, in a verbal shell game, the CAs make it sound like someone with an expensive certificate is trustworthy (in the end-user's value system). -----Original Message----- From: owner-cryptogra...@metzdowd.com [mailto:owner-cryptogra...@metzdowd.com] On Behalf Of Andy Steingruebl Sent: Wednesday, September 15, 2010 4:12 PM To: Peter Gutmann Cc: cryptography@metzdowd.com Subject: Re: A mighty fortress is our PKI, Part III On Wed, Sep 15, 2010 at 8:39 AM, Peter Gutmann <pgut...@cs.auckland.ac.nz> wrote: > Some more amusing anecdotes from the world of PKI: Peter, Not to be too contrary (though at least a little) - not all of these are really PKI failures are they? > - There's malware out there that pokes fake Verisign certificates into the > Windows trusted cert store, allowing the malware authors to be their own > Verisign. The malware could just as easily fake the whole UI. Is it really PKI's fault that it doesn't defend against malware?

Similarly here - non-EV CAs bind DNS names to a field in a certificate. No more. They don't vouch for the business being run, and in any case any such "audit" would be point in time anyway. I suppose way back when people "promised" that certs would do this, but does anyone believe that anymore and have it as an expectation? Perhaps you're setting the bar a bit high? BTW - do you have pointers to most of the things you've reported? I'd love to get the full sordid details :) - Andy --------------------------------------------------------------------- The Cryptography Mailing List Unsubscribe by sending "unsubscribe cryptography" to majord...@metzdowd.com --------------------------------------------------------------------- The Cryptography Mailing List Unsubscribe by sending "unsubscribe cryptography" to majord...@metzdowd.com
