Hello,
thank you. there was a small typo in the link you posted. it is
http://web.monkeysphere.info/
some questions.
Monkey sphere says:
Everyone who has used a web browser has been interrupted by the "Are you sure
you want to connect?" warning message, which occurs when the browser finds the
site's certificate unacceptable. But web browser vendors (e.g. Microsoft or
Mozilla) should not be responsible for determining whom (or what) the user
trusts to certify the authenticity of a website, or the identity of another
user online. The user herself should have the final say, and designation of
trust should be done on the basis of human interaction. The Monkeysphere
project aims to make that possibility a reality.
will try this out. in the meantime other questions related to browser
certificates
1. How do we know which CA's (root/intermediate) have certified a domain
xyz.com?
2. How do we know the CA trust chain. i.e. who all are the root CA's and who
are the intermediate CA's and which root CA is associated with a given
intermediate CA?
3. Can we make the browser notify us if a domain was certified by an
intermediate CA?
4. Say domain xyz.com is certified by CA 'A' and CA 'B' whose
(root/intermediate) certificates are available in the browser. if i find CA
'B' to be malicious how can i get domain xyz.com certified by CA 'A'?
Thank you,
Sarad.

If you have any further information on it or any other countermeasures implemented, please do keep us in loop. this attack is upsetting.

For IP if you'd like.
Over a decade ago, I observed that commercial certificate authorities protect you from anyone from whom they are unwilling to take money. That turns out to be wrong; they don't even do
Chris Soghoian and Sid Stamm published a
simple "appliance"-type box, marketed to law enforcement and intelligence agencies in the US and elsewhere,
certificates issued by *any* cooperative certificate authority to act as a "man-in-the-middle" for encrypted web
Their paper is available at
http://files.cloudprivacy.net/ssl-mitm.pdf
What I found most interesting (and
surprising) is
surveillance is widespread enough to support fairly mature, turnkey commercial products.B B It carries some significant disadvantages for law enforcement -- most particularly it can be
detected.
I briefly discuss the implications of
certificates that. paper today that describes a that uses bogus traffic. that this sort of potentially can be this kind of surveillance at http://www.crypto.com/blog/spycerts/
