RE: Google security concern?

Patrick,
This seems to be yet another way in which phishers/spammers/malware
folks are getting clients to visit their sites.  There could be
multiple reasons for this tactic -

1) Click-thru/banner/visitor revenues
2) Sell their product
3) Compromise the client to install some backdoor app (as you
suggested in your email with the browser exploits)

There are have been many reports which have indicated that
phisher's are installing backdoor apps on client machines for use
by spammers/virus writers, etc... to funnel their future attacks
through them.  They are essentially using the infected clients as a
zombie army.  Check out some of the advisories at LURHQ -
http://www.lurhq.com/advisories.html

As to Google's part in this - you are correct in asking some of
these questions.  I do not know the exact details for how Google
ranks sites, however you may be onto something with regards to the
intentional mis-spellings as that would bump them up to the top of
the list.

Here is some info on Google's Cache feature -
http://www.google.com/help/features.html#cached

Basically it states that if there is no cached link, then they
either have not indexed the site (which is not the case with your
links since they returned results) or the site owners have
requested that Google not cache the data.  This seems most probable
as they would want people to visit their site directly, get
infected and then the owners would have an IP list of infected
clients.

Hope this info helps.
