Hi,

Depending on your trusted-CA package for your SSL client, this
should not verify. There are various ways to confuse SSL clients.
Especially GUI based web-browsers allow to play tricks where
you cant decide whether you are prompted a correct certificate.
Some do not check the signature at all. If in doubt, if there
is any popup on a HTTPS site, theres someone playing games.
I am going to release slides from a speach regarding that topic soon.

I've been getting SSL certificates from various websites recently that are
apparently from a "VerySign Class 1 Authority" - note the 'y' in VerySign.
The certificate expired 6 December 2002.

The data in Issued To and Issued By are identical.

This smells very much like an SSL hijack attempt - can anyone shed some
light on the situation?

Chris
