Update: Microsoft tests fix for IE bug as exploits appear
It aims to add patch on or before its April 11 security update

News Story by Nancy Gohring

MARCH 27, 2006 - A recently identified security hole in the Internet Explorer browser is being exploited, and Microsoft Corp. hopes to include a fix for it in its April 11 patch or possibly sooner, according to a posting on a Microsoft blog.

So far, attacks are limited in scope, Stephen Toulouse, head of Microsoft's Security Response Center, wrote on the center's blog Saturday. Today, however, Web security company Websense Inc. said it has found hundreds of sites taking advantage of the weakness and that the number of such sites is rapidly growing.

The vulnerability, which was first identified last week, allows hackers to entice Web surfers to visit Web sites where malicious code can be automatically run on the visitor's computer (see "Exploit now publicly available for unpatched IE flaw"). It exploits a vulnerability in the way that IE renders HTML and affects Windows 2000, Windows XP and Windows Server 2003, Toulouse said. Users of IE 7 Beta 2, the most recent version of IE, won't be affected by the bug, Microsoft said.

"We're working day and night on development of a cumulative security update for Internet Explorer that addresses the vulnerability," Toulouse wrote. The update is being tested and is expected to be released as part of Microsoft's monthly security update, which is scheduled for April 11, he said. However, Microsoft could release the fix earlier if the threat grows, he said.

The Web sites found by Websense download different types of malicious code, including back doors and Trojan horses, onto Web surfers' machines. Back doors bypass regular authentication requirements, enabling unauthorized access to computers, and Trojan horses are malicious programs disguised as legitimate applications.

Microsoft is working with industry partners and law enforcement to remove Web sites that are exploiting the vulnerability, Toulouse said.

Web surfers can avoid the attack by turning off Active Scripting, Microsoft said.

The vulnerability is the third such IE bug to surface within the past two weeks and is considered the most serious because it is relatively easy to exploit.

Attacks now underway according to this PC Mag article:

Instead, it has warned users of its browser products to be careful when opening email attachments and to avoid untrusted websites

Does anybody in the whole world not know this?

I think there are many that are not well versed in the art of avoiding trouble on the internet!

Ok, I wonder if I could have been (hacked/exposed/whatever?) because when I got back to my work computer after this weekend, it now has the "about blank" browser-redirector on it.

I have no earthly .....how this happened...BUT, alot of my work involves email attaching (sending, mainly....NOT opening).

Might any kindly freepers help? Thank you in advance!

Meanwhile, a report published in September by Symantec rated Internet Explorer as safer than Firefox.

In what alternate universe are they living in?

[zeugma]

What browser are you using?

[spankalib]

IE

apparently, I'm close to "licking toads"? LOL

[Ernest_at_the_Beach]

Have you got anti-spyware stuff installed?

[Ernest_at_the_Beach]

So do you use Outlook for working with the e-mail?

Do you have a firewall , either hardware or software installed? My questions here are real basic, others here are much more knowledgeable about windows stuff.

Searching freerepubli9c for spyware will get you many threads with discussion although this might be a good one to start on:

Free website to list programs with spyware

backhoe always has some good suggestions.

[spankalib]

Yes, Adaware & Spybot don't detect it, even a registered version of Webroot Spysweeper failed to detect it. AVG? nope. Panda & Housecall, the online scans, do not detect it.
Seems like I've got to do it manually, I think, via Hijack This!, but am leery of messin w/ da registry!
As an aside, many "free spyware scans" detect it....like "Spyware Doctor" BUT....yep, you already know what I'm gonna say, right? (thay want $$ to get rid of it). Sigh.
I'm going to try bit defender.....will let you know.

OK, so I see you are not a newbie to dealing with the crap.

Not sure I'll be of much help.

[zeugma]

Well, if it works for you :-)

Sorry, but I can't help you with IE issues. 

On the bright side, "about:blank" is probably the least offensive webpage you could have been redirected to! 

[ShadowAce]

From what I've read on this thread, it sounds like HiJack This! should work. Rather than a virus or spyware, your registry has been hijacked. That's probably why none of the normal programs are finding it.

Let us know how bit defender works and if you try Hijack This as well. I'm curious.
