Group Posts Program That Exploits Windows


By Helen Jung, AP Business Writer


SEATTLE�A group in China released a program Friday that lets hackers exploit
a flaw in Microsoft software and take over a victim's computer over the
Internet.
The program, released nine days after Microsoft Corp. announced the flaw,
has turned an embarrassment for the company and inconvenience for customers
into a near-emergency.

The program, posted on the group's Web site, takes advantage of a
vulnerability in nearly all versions of Microsoft's Windows operating
system, including Windows Server 2003, touted as Microsoft's safest ever.

The Redmond software giant has urged corporate and home users to download a
free software fix, but many consumers�particularly companies with hundreds
or thousands of computers at risk�probably have not yet done so, said Marc
Maiffret, co-founder of eEye Digital Security Inc. of Aliso Viejo, Calif.

"Three times a year, there are (flaws) this bad," Maiffret said. "This is
one of those times."

The flaw, discovered by western Poland researchers called the "Last Stage of
Delirium Research Group," affects Windows technology used to share data
files across computer networks. It can allow attackers to seize control of a
victim's computer, letting them steal data, delete files and access e-mails.

The flaw is an embarrassment to a company that has dedicated millions of
dollars to its highly trumpeted Trustworthy Computing initiative, in which
Microsoft has been emphasizing security in writing code.

The Chinese group, Xfocus, did not contact Microsoft before posting the
sample code, said Jeff Jones, Microsoft's senior director of Trustworthy
Computing security.

"We continue to believe that publication of exploit code in cases like this
is not good for customers," Jones said.

Xfocus, described on its Web site as a nonprofit and free technology
organization founded in 1998, did not immediately return an e-mail request
for comment sent Friday by The Associated Press.

Russ Cooper, of Herndon, Va.-based TruSecure Corp., questioned why the group
chose to post the code. "I don't understand the point behind doing this," he
said. "This isn't healthy for the 'Net at all."

So far, Microsoft has not heard of any instances of the code being used.
Microsoft said companies with strong firewalls commonly block the type of
data connections that outside hackers would need for such attacks.

But Cooper said there are other ways to breach firewalls. He said attackers
could gain access by targeting legitimate users who connect into the
computer network from an unsecured remote location.

He added that the code can be used to attack one site at a time but that he
expects someone will soon "make the leap to turn this code to a worm" that
could attack Internet sites randomly, en masse.
