MS Word Zero-Day Exploit Found
subbers writes "A zero-day flaw in Microsoft Word program is being used in an active exploit by sophisticated hackers in China and Taiwan, according to warnings from anti-virus researchers. The exploit arrives as an ordinary Microsoft Word document attachment to an e-mail and drops a backdoor with rootkit features when the document is opened and the previously unknown vulnerability is triggered. From the article: 'The e-mail was written to look like an internal e-mail, including signature. It was addressed by name to the intended victim and not detected by the anti-virus software.'"
This type of spam isn't too bad given traditional spam methods, as smarter users won't open attachments from people they don't know. The dumb ones generally dont know a word doc from an EXE so hopefully they are also avoiding most attachments. However there have been a few articles on the future of spam and local data mining. Consider what would happen if the next virus your co-worker got looked through their emails, found the last word document they sent out, and then copied that but embedded this exploit. They might even say, its been revised please have another look. The chances you wouldn't open this are extremely low, and especially when you are opening a normally okay attachment. It is coming from someone you know, from their computer, through their isp, and even is styled the same way as normal. The question is how will we attempt to combat such things? It doesn't just have to do with holes in microsoft office, or any other format too. When local data mining is combined with exploits in any other common formats (give the image exploits of other os's even) you now have a delivery method that can almost promise execution.
Is there already a race on for releasing a patch? Can the anti virus companies detect it?
I guess it will be a mess if they dont start detecting it soon.Of course MS will be flamed again.

A recent slashdot story asked the question, "Is the internet that fragile?" When I see stories like this, it reminds me and should remind everyone of the other fragile technology(ies), Microsoft and their baggage.
Consider that many on-line applications for jobs require cover letters and resumes as WORD attachments. Now, consider the temporary suggested workaround:
This is disruptive and lose-lose, either organizations heed the advice, and now for as long as it takes to fix Microsoft's problem applicants will have their documents blocked, or some of these hackers profuse their new hack and compromise organization's infrastructure.
Microsoft has made our bed, and now we all must sleep in it (ick). It's unacceptable that such an exploit could so easily take control and wreak damage. Why can a simple e-mail get in and twiddle with what should be administration-priveleged system resources? I know the recommendation is everyone accessing their XP as non-administration users, but how do you enforce that, especially when for so long so many of the out-of-the-box configurations make administration rights the default login?
I must say I admire Microsoft's savvy more each day in their EULA -- crafted to absolve Microsoft of any responsibility for bad things happening to users because of Microsoft's software. It must be reassuring to offer a product and not have to assume responsibility. What a unique privelege
Of course, a good outcome from this would be to reconsider the global transport of exchanging documentation (e.g., resumes and cover letters, etc.) to something a little less Micrsoft, a little more open, and a little less prone to exploits. That can't happen soon enough.
How many EXTREMLY critical flaws is it already Word documents have?
How is it possible these things still keep coming up.
It's not even funny anymore...
Is this an exploit that somehow grants malicious code access privledges even beyond the user's access level, or does this simply allow execution of arbitrary code at the access level of the user who is running Word?
If it is the former, then it's a very serious flaw. If it's the latter, then it's a serious flaw, but one that will only really adversely affect people stupid enough to run as Administrator all the time, despite Microsoft's own warning against such idiotic practices.
If it is the latter, then I have further justification to use against the users who have complained about using their Administrator privledges.
STOP MISUSING APOSTROPHES, YOU MORONS!!!
The exploit only works properly in Office 2003 (and crashes Office 2000). Given that emailed DOC files are pretty much required for millions of people to do their jobs, the most effective short-term workaround is use something else to read DOC files.
For all we know, the Zombie Overlords live in Scranton, NJ or Brazil.
They're just using the incredibly insecure servers one can find in China and nearby countries to base the attacks from.
Now, that doesn't mean they aren't Chinese - in fact, that's quite possible - just that where an attack comes from is frequently not where the people who set it off are based in.

WRONG! Modern viruses, for YEARS now, have set their 'sent from' address as a random address they found in either the internet cache, or ADDRESS BOOK of the infected machine. Often many people in a random address book already know each other. That means the virus has a very good chance to be sent 'from' someone you know (in the address line), although that person didn't send it.
Don't trust an attachment just because it appears to come from someone you trust. If you aren't expecting that exact attachment, or there isn't very very clear working in the email that would make it relevant to something you know about rather than some generic topic, don't open it. Take two seconds and email the person back and ask what it is.
Trusting an attachment just because it appears to come from someone you know is STUPID.

Why did that get modded insightful?
If anything, it's barely "informative".
In the corporate world, using Open Office is like driving an electric scooter. Sure, some people think it's cool because it's not a gas-sucking-Hummer, but it's a piece of shit scooter.
Is there perfect compatibility between business users with Word. and OO? Absolutely not. It's totally unacceptable for corporate use with other folks that use MS Word regularly. Same with Excel and the OO varient. Especially if you're dealing with anyone "higher up" or you consult for folks, or you just want to know your files will be opened successfully, without requiring any extra effort from the person you sent it to.
Reccomending OO because MS Word has a critical flaw makes sense for SOME home users, people who don't share files with MS Word users, etc. But for the most part, it's a bad reccomendation unless you're just using OO like a slightly more advanced Notepad. As soon as you tap into truly in depth MS-Word features, compatibility problems arise. In my experience, all open/free/generic word processors are going to have to be used as glorified Notepads if you hope to attain high quality cross-product/platform compability.

It a medium of communications, and text is the only content which can be assumed to be usable by any recipient. Sending anything other than plain old text, unless there is prior agreement between both sender and receiver, is a hinderance to communications.

They do critical MSWord docs back and for with clients and the FDA in Wash. D.C. all day long, and I really don't think they accept how risky this is today, particularly if a document comes in forwarded from a reliable source that has had the malicious RootKit somehow patched onto an other wise legitimate document that they need to file with the FDA.
Of course that makes me wonder how the FDA handles a malicious MS Word document. They are no different than anyone else in receiving zero day exploits.
Each time a zero day or other serious problem hits, I remind them, but they are literally afraid of having to learn something new, & so stick with the MS offerings.
Since all these factors can be spoofed, insist that anyone who is sending you an attachment first send you a plain text e-mail advising you that he/she is about to send the attachment. This message should include your name in the body in the text, a brief description of what is being sent, and maybe even a worded statement of the date and time to confirm the time stamp. You could even establish a code word or phrase with regular correspondents and ask that they include that in both subject line and text body. Conversely, if you do receive an unexpected attachment, but it appears to be from a known correspondent, e-mail them and ask if they sent you a message with attachment with subject line XXX at such and such a date and time.
Seem like a lot of trouble to go through? Compare the momentary annoyance to the time and cost of ridding your machine of a nasty virus. I've known people who are well aware of the ticks and trades of virus sending assholes who get infected simply because they get careless or lazy and don't take steps such as the above.
