Apparently there's a new virus out there. I've seen it several times already today.

Worm Attacks Yahoo E-Mail

Mass-mailing worm exploits a vulnerability in the Web-based e-mail,
but
its
impact is low.

A mass-mail worm that exploits a vulnerability in Yahoo's Web-based
e-mail
is making the rounds but the impact appears to be low, security
vendor
Symantec said today.

The worm, which Symantec calls JS.Yamanner@m, is different from
others
in
that a user merely has to open the e-mail to cause it to run, said
Kevin
Hogan, senior manager for Symantec Security Response. Mass-mail
worms
have
usually been contained in an attachment with an e-mail note
encouraging
a
user to open it.
The worm, written in JavaScript, takes advantage of a vulnerability
that
allows scripts embedded in HTML e-mail to run in the users'
browsers.
Yahoo
users should be able to modify their settings to block the zero-day
exploit,
Hogan said.
Symantec rated the worm a Level 2 threat, one notch above its least
harmful
ranking. Hogan said the worm did not appear to be spreading widely,
and
he
did not anticipate the threat level rising.
How It Spreads
When activated, the worms then sends itself to other users in the
victim's
address book who also use Yahoo e-mail with the suffixes of
@...
or
@yahoogroups.com. The worm mimics a function within Yahoo's Web mail
called
Quickbuilder," which allows a user to add contacts in an address
book
from
received e-mail, Hogan said. The process, however, is transparent to
the
victim, he said.
The harvested e-mail addresses are sent to a remote server. Users of
Yahoo
Mail Beta do not appear to be affected, Symantec said.
The worm also opens a browser that displays a Web page that does not
appear
to contain malicious content.
Although Yahoo's Web e-mail has not been fixed, users are advised to
update
virus and firewall definitions and block any e-mail sent from
av3@....
The subject line of the e-mail with the worm says "New Graphic
Site,"
and
the body says "this is test."
Yahoo officials could not immediately be reached for comment
