The Truth About a Claimed Firefox Exploit
A colorful duo of young hackers at the Toorcon security conference presented evidence Saturday that suggested a previously undocumented flaw in Mozilla's Firefox Web browser is actively being exploited to compromise machines of users cruising the Web with the browser. This story has been pretty widely reported over the past few days, but a few key facts have been absent from most of the coverage I've seen, and I wanted to try to help set the record straight on this.
The Toorcon talk was given by Mischa Spiegelmock a software engineer for Six Apart's LiveJournal blogging service, and a guy speaking under the pseudonym "Andrew Wbeelsoi." They prefaced their presentation by calling on security researchers everywhere to stop publicizing and fixing software security vulnerabilities.
"We do have exploits for all the stuff we're going to show you," the 21-year-old calling himself Wbeelsoi said. "We'll give them away to anyone who proves their actions are going to be politically motivated. We don't care what side you're on as long as you commit yourself to destruction."
Both speakers lectured at length about ways to cloak your identity online to engage in criminal activities, ranging from creating botnets to installing spyware on users' machines. They ardently urged those in attendance to use their knowledge to "ruin things" as much as possible for Internet users.
One way to accomplish that goal, the two claimed, was to exploit a vulnerability in the way Firefox handles Javascript that they said could allow malicious Web sites to install spyware if users merely browsed a specially configured Web site that took advantage of the flaw in the way that they described.
Here are the parts I haven't seen reported yet elsewhere on this:
Spiegelmock admitted to me Saturday evening that the duo's research wasn't quite as solid as they led people to believe. Turns out, they confirmed that the bug they found could be used to crash Firefox, but that they hadn't bothered to do the work to tell whether that crash could be exploited to allow bad guys to install software. "We were just trying to have some fun up there," Spiegelmock said.
Window Snyder, head of security strategy for Mozilla stood next to me as Spiegelmock explained; she was not amused. Spiegelmock gave Mozilla a statement confirming more or less what he told Window and me Saturday evening, which Mozilla has since posted on its site.
Also, Wbeelsoi, or "Weev" as he is called by friends, is part of a group that calls itself "Bantown," a loose-knit outfit that claimed responsibility for a fairly high-profile Javascript attack against close to a million LiveJournal users, an attack that Security Fix profiled in January.

Er, Window is a "she". Did you really attend ToorCon?
This whole situation sounds familiar. David Maynor did the same thing at Black Hat: showed a supposed exploitable vulnerability, then later could not show any evidence that there was anything, even a crasher. Although he has yet to admit that publicly... instead he is just staying silent.
Oh I know, you saw the "exploit" in person. But actually, you saw a faked demonstration just like everyone else.

Why the yellow shirts? Black hats with a dress code for their members?
I think these two wanna-be's were simply looking for some cheap publicity. Even so, I'm sure the Mozilla guy asked local P.D. to dust the podium for fingerprints afterwards.
The truly skilled and malicious hackers, those working out of a Bulgarian or Moscow apartment, would never expose themselves or their Russian mob bosses by speaking on a podium. Or by wearing a yellow shirt in public.

A free pass to slander a browser?
Is this a free pass to slander a browser? If this was an attempt at a joke, I can tell you many supporting the movement to Firefox aren't amused.
The real joke is how these clown hats are given free reign to slander and the media for incessantly hopping on its bandwagon prior to learning the facts.

Barber Sink -- Nice anagram of my name for your sig there.
My favorite is Biker Barns.
I hung out with Window at Toorcon several times, and I already wrote that she was with me, so this is obviously a typo, and it has been fixed. Anyway, thanks for not being obnoxious about it.

I suspect the vulnerability is real. I also think someone informed these loud-mouthed morons that they were now on an FBI watch list for talking about creating a "blackhat communications network". They're trying to cover their butts. Too late. I don't think anyone should get too comfortable just yet. I suspect the "we were only joking" part is the real hoax.

I find it highly suspect that a LiveJournal developer and a member of a group that hacked LiveJournal are friends. Someone at Six Apart needs to take a long, hard look at Mischa Spiegelmock...

These jerks must be prosecuted. How many sleepless nights we have to bear to amuse them? Behead them. BTW: this means to be humorous except the call to behead them.

BanTown have a history of making misleading, overstated, or downright false claims about their "attacks". They're a group of trolls, and calling them Black Hats is, imo, a disgrace to the real thing. I'm still not convinced that the attack on LiveJournal happened the way BanTown described it.
Anything directly associated with Bantown has a huge credibility problem from the moment it appears.

How long before U.S. Cert drops their "warning" about possible a Mozilla exploit? It's still up on their site.
Funny, there's still _several_ unpatched (but documented) Microsoft vulnerabilities that haven't appeared on U.S. Cert's site.
I'm not connecting the dots, but some might.

The LJ developer probably discovered, at the podium, that Mozilla wasn't written in perl and that was the end of the vulnerability assessment.

Brian,
How big a problem is the Firefox-JavaScript hole if one installs Firefox's JavaBlocker extension?

These two clowns say, in part, "We don't care what side you're on as long as you commit yourself to destruction." Let me pose this question...would it not be the sign of a true leader to lead by personal example? If they want their followers to destroy things belonging to other people, why don't these sophomoric, self-centered, bone-headed brats show us all how it's done by destroying themselves first?

If these two sophomoric, self-centered, bone-headed brats want to be real leaders, heroes of the first caliber, let them show us how it is done by first destroying themselves...or at least their computer systems.

Does this mean that I have to stop telling my friends that firefox is the Best web browser around.
I think not!.
I switch between opera and firefox, just to confuse boneheads like these two.
As for self destruction for these two,time will eventually make that a reality.

Listen up and listen well. If all of you would quit running around on the internet with anything other than a 'user account' all this crappy hacking would be a thing of the past.
I didn't say a guest account, I said a user account. You can't install software on a user account, so hacks are a thing of the past. Wise up people and get informed.

Saw the report of the -alleged- flaw yesterday (Mon) and ignored it.
Dead giveaway was that they named it "unfixable".
Nothing in software is unfixable. Hence the source had an obvious bias.

They have no other reason for commiting career suicide other than if they are going to be paid some money for this slander.
Many hackers outthere know of a number of hacks with IE that have been exploited for years and these don't seem to have been aired or talked about by all of those columnists who decided to write about this...
This stinks of some sort of "Get the facts" through the back door campaign...It has all of the hallmarks of a Microsoft drive by!

it seems to me that these young lads are playing a little game of follow the carrot. They will be mostly interested in other people trying to hack them. It will be really exicting to be watched and still be able to play spy vs. spy.

I'm not so sure that the wireless driver issue was a hoax. However, the firefox issues appear to be much more suspect. I don't think you can compare the two. In any event, these ppl appear to be idiotic and have gotten a lot of bad press for mozilla. Is this a black-hat bloc event designed to create FUD?
Posted by: r | October 4, 2006 9:56 AM
From what I'm hearing, if you were actually in the audience for their presentation -- and had half a brain -- it was pretty obvious that this presentation was a joke. Apparently some reporters didn't meet one of the above two qualifications.
Even some of the statements that Brian describes here make it prety clear:
"We don't care what side you're on as long as you commit yourself to destruction."
"They ardently urged those in attendance to use their knowledge to "ruin things" as much as possible for Internet users."

The issue isn't whether the wireless MacBook hack exists or not. There is a possibility that Maynor discovered something; it is his inablity to tell a straight story since then that makes people question him. The issues with the wireless hack are 1) was the demo a fake (evidence is pointing in that direction) 2) should reporters have done a better job initally the story (again, suggests yes) and 3) did Maynor act responsibly and tell Apple about the flaw (currenly in dispute, and now nobody is going to talk). Keep in mind with #3 is Maynor is now claiming a flaw in FreeBSD as well, but has not notified anyone (Sam Lefler) about the problem with FreeBSD.

ROFL! well they certainly got the publicity that they were after, didn't they? And they successfully tested out the waters for whatever other projects they might have in the future.
Script kiddies comes to mind, except they look too old to be kiddies. Definate wannabes... now it remains to be seen if they turn into something other than wannabes. If so, they'd better learn how to hide as well as hack, because the entire world now knows more about them than is safe.
Posted by: Crystalwizard | October 5, 2006 5:26 PM
Doug, that shows you that the way Mozilla handled the problem (damage control) was poor and the Mozilla powers took far too much time to clear the air on the matter.
Window was at the meeting, was she not? If so, she would have known if it came across as a joke and should have rallied the Mozilla troups to squash that joke from gaining any media traction whatsoever.
Posted by: Traction | October 5, 2006 9:32 PM
take this into consideration, after idk how many patches windows came out with there are still flaws and holes, think of a web browser the piece of software that allows you to travel the web and catch these nasty things do you really think there gunna catch every flaw. Java is also a big problem.. No matter how hard any company trys, there software will have leaks and it will be exploited. THE END.. P.S - BY A FIREWALL LMAO
