Speaking of computers fubar'ed by spyware, I just
found a particularly
nice example of a phishing attempt.  SpamAssassin
had tagged it with the
astronomical score of 136.3 thanks to SARE.

The mail originated from 68.77.56.130 (an
ameritech.net DSL connection,
right now not pingable) and loads some images from
www.citibank.com.
It links to http://61.128.198.51/Confirm/ - an IP
address hosted by
Chinanet (transit to there supplied by Savvis from
my point of view).

That page does something interesting: it meta
refreshes itself to
Citibank's corporate homepage but also pops up a
window
(/Confirm/pop.php) requesting the user's card#, PIN
(twice) and a
new PIN.  The main page being citibank probably
lends some credibility
to the scam.

This attack won't work if your browser blocks
popups, or if you remember
that the padlock icon in the status bar is what
tells you the status of
a connection, not a "128-bit SSL" or "Verisign
trust-e" or whatever logo
inside the webpage.

It's disheartening to see that this website is still
online after
several days (I received the scam mail received
Friday morning).

I'm thinking that Citibank will cease to be a target
if they give (ok,
it's a bank - sell) their subscribers a hardware
token that requires
presence of the ATM card when the customer wants to
use online banking
facilities... as several banks here in the
Netherlands do.
