Trust is relative. Why would you trust a logo?

If we look at any large brand phish site these days they have “the security logo”, some call it a seal, smart icon or security stamp. You know the ones, they claim to “verify your site in real time” or give”confidence and assurance to trust the identity of your web site“.
The URL both logos link to is the same:
:evil:Phish:
https://seal.verisign.com/splash?form_file=fdf/splash.fdf&dn=SCGI.EBAY.COM&lang=en
:cool:eBay:
https://seal.verisign.com/splash?form_file=fdf/splash.fdf&dn=SCGI.EBAY.COM&lang=en
You could even try it for yourself here.
I was going to call this post “Trust me, I have a logo” - take your pick 
They are pretty easy to copy, even the ones with the custom text on could be faked easily. Their value comes from people associating them with data security and through that perception they inspire confidence. Please remember, They are just logos! Companies use them because they provide reassurance and most importantly they increase sales. (Verisign have a good pdf on profitable usage).
“71 percent of UK online shoppers will only make purchases through sites that include a trust mark.”
I’m not just picking on the SSL guys here, they really do provide you better options than “logos” as VeriSigns’ Tim Callan notes on a recent blog. EV certs are available for $$$$, but for many the logo is good enough:eek:
Oh, while I’m on the subject, the card companies have “nice logos” too 
Please think of these logos as a security reminder, you should express as much caution on sites displaying them as any other site, and if need be re-enter the URL by hand in a new browser window.

Nice catch. You might also note that it was / is possible to completely fake the process and validation. While anyone can copy the seal and point it to their own site, it was / is possible to use Verisign’s own validation popup in order to validate a fake site.
This was reported to VeriSign a very long time ago, but they are still vulnerable to variations of the same technique (so it will be withheld for the time being).

The sight of the logos makes customers feel safe, no matter what the site
I like to deal in real examples and the popup above is just one issue in whole chain of validation. $25 SSL certs have diluted the value of https and the padlock icons for instance.
But the situation is so complicated to Average-Joe that linking any of the popus could give the indication of security. Even a certificate/seal owners own!
…Then there is the whole EV argument, why should small business pay $1000 for an EVcert when they just want a simple shop site with paypal as a gateway because the community have been told that the green bar is the new padlock.
…and that’s broken too IMHO, popup a new window with no toolbars, populate the top most part of the window with a fake green browser strip and load the phish site in a frame. Oh hold on a sec… Phishers did that with the good old SSL padlock years ago!
