Microsoft Browser Holes Lead to AIM, Dial-Up Attacks

SAN FRANCISCO (Reuters) - Security holes in Microsoft's Internet Explorer browser have been exploited by hackers to hijack AOL instant messaging accounts and force unsuspecting Web surfers to run up massive phone bills, computer experts cautioned on Friday.
Some Internet Explorer users are also finding that malicious Web sites are secretly slipping trojan programs onto their computers, which could prove an even more dangerous exploit, said Drew Copley, a research engineer at Aliso Viejo, California-based eEye Digital Security, who discovered the original security vulnerability.
Such stealth programs can include keystroke loggers that record everything a person types or software to erase the hard drive, among other things, he said.
Microsoft MSFT.O has released a patch for the original hole, which was reported about a month ago, said Stephen Toulouse, security program manager for Microsoft's Security Response Center.
The company is looking into what it says are variations of the original hole that have been discovered since then that the patch does not fix, Toulouse said.
"We will release a fix for the variations," he said.
Security experts are reporting the variations as new security holes, disclosed within the past three weeks and used for different types of attacks, Copley said.
Microsoft and eEye Digital Security said they have issued information for temporary workarounds.
In general, the attacks are accomplished by leading Internet Explorer users to a malicious Web site, either by sending an e-mail with a link to the Web page or distributing a link through instant messaging, Copley said.
When the Web site appears, it downloads code that can execute commands on its own onto the unsuspecting computer user's machine, according to Copley.
An attacker has written a program that uses a security hole in Internet Explorer to hijack an already running AOL Instant Messenger account, changes the password and send a message to the buddies list with a link to the malicious Web page, according to postings on the Bugtraq security e-mail list.
The Web site the posting listed as stealing the AIM passwords appeared to have been shut down.
An AOL Time WarnerAOL.N spokesman said the company was looking into the issue.
'PORN DIALER'
Another attack is being accomplished by sending computer users to Web sites -- typically porn sites -- that change the computer's dial-up settings to an expensive long-distance phone number without the user knowing it, said Richard Smith, an independent Boston-based security researcher.
In the so-called "porn dialer" attack, victims are being charged as much as $5 a minute instead of paying their normal Internet service fee, he said.
A third type of attack steers computer users to pay-per-click Web sites, where the spam marketer gets paid each time someone goes to the Web site, Copley said.
"These kinds of bugs are really spooky" because they work in the background, undetected by the computer user, he said. "With these kind of holes, a lot of roaches crawl through."
Computer users can protect themselves by applying patches, following the workaround instructions or changing their settings in Internet Explorer to prompt them before a Web site downloads programs that can execute on their own, Toulouse said.
Also on Friday, anti-virus company Global Hauri of South Korea warned about a new medium-risk computer worm that spreads through Microsoft Network's MSN Messenger system, attempts to connect to a porn Web site and passes itself around to others in the victim's contact list.
Toulouse said Microsoft was looking into the matter.

Clearly, Micro$loth is
screaming at it's customers, "DO NOT use Internet Explorer. It's full of bugs. Use another browser, such as Netscape, Mozilla, Opera, etc."

Let me be the first to say it. This is why I use Linux!! Since I switched I have not had my homepage changed to a porn site, I have not had to worry about virus's, and I don't receive ANY spam, ZERO SPAM!!
I run a Linux firewall and the hits I receive everyday from blaster is off the scale!!
I agree with the writer of Blaster, Gates needs to stop making money and fix his software!!!

These particular holes were patched quite a long time ago, for those who bothered to update.
But it may be a good idea to download and use DCOMbobulater from Gibson Research, because as the article points out, related exploits are still possible. Why not just turn DCOM off if you aren't on a company network that requires it?

No. MS has only released partial fixes that don't address the underlying problems. This has nothing to do with the DCOM problems.

"Bottom line: Don't use IE for anything you value -- online banking, etc." I was a confirmed Netscape user. Until it began crashing for no reason, bringing down the entire PC. I uninstalled it, downloaded a fresh copy, installed it. Same problem.
Eventually I reformatted the HD, installed a new copy of Netscape; same problem.
Querying Netscape "technical support" was like talking to the Sphinx, except that the Sphinx is more talkative.
Finally I threw up my hands, installed IE and have never had a problem.
Zone Alarm Pro, McAfee, and other tools keep me deloused; I install "critical updates" as they appear.

or changing their settings in Internet Explorer to prompt them before a Web site downloads programs that can execute on their own, Toulouse said. Wouldn't it be nice if instead of just making this statement the instructions for actually doing it were posted?

Zone Alarm is good. BlackIce is better and more configurable and co$ts a bit of change. Even if you use a software firewall the best choice is a good hardware firewall such as a personal SonicWall or Netgear unit. DOS attacks can lag down your TCP/IP stack so badly that it causes you many problems (even with the very best software firewall).
Ultimate solution is to have a good hardware firewall as your router AND a good software firewall on your server or workstation as a failsafe. I have both and both combined have protected me from every virus attack to date and DOS attacks fail miserably. I do a lot of IRC and with my Conservative opinions and big mouth I get a lot of them. :)

Oh, yeh; 'Opera' and 'AtGuard' are the way to go! No problems, nobody can get a response or even a cookie unless you specifically say they do, and NO malicious scripts rerouting you to Pr0n sitez or virus'Z infecting your machine.

I probably have less (!) keys on my keyboard, than you have Trojans, virus's, and worms, in your computer.
People talk about all the problems with Windows, but keep using it. I fixed my problem.
I installed Linux, and I have never looked back!!

For any readers who don't know what a "web bug" is, click on this link.
http://invite.ke2.informative.com/images/invite.gif (The link is related to the "front door" at Virtual Dr., a computer help forum I sometimes frequent, and it's like a turnstile, telling the site owners how much site traffic there is). You'll open up a blank window. Right click, choose Select All, and if you squint you'll see a small dot in the top left corner.
That's all it takes, by the way, for a spammer wanting to know if your account is active, to know you opened up his sewagemail while on-line. It costs him no bandwidth. If you feel compelled no matter what to open up suspicious mail from just anyone, at least do it off-line.
