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 [EMAIL PROTECTED], 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 @yahoo.com
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 [EMAIL PROTECTED]
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.
