Honeynet Project finds way to fingerprint Conficker infections

Just days ahead of an April 1st activation date for the Conficker worm, a pair of security researchers from the Honeynet Project have scored a major breakthrough, finding a way to remotely and anonymously fingerprint the malware on infected networks.
Now, with the help of Dan Kaminsky and Rich Mogull, off-the-shelf network scanning vendors, including the freely available nmap, have the ability to quickly detect Conficker infections.

Firefox 3.0.8 fixes two code execution holes

Mozilla has released Firefox 3.0.8 to fix a pair of code execution holes that put users of the browser at risk of drive-by download attacks.  It includes a fix for one of the flaws exploited during this year’s CanSecWest Pwn2Own hacker contest.
The update also fixes a separate zero-day flaw disclosed earlier this week on a public exploit site. Both issues are rated “critical,” Mozilla’s highest severity rating.

Researchers can ID anonymous Twitterers

Researchers at the University of Texas at Austin have taken a close look at the way anonymous data can be analyzed and have come to some troubling conclusions [infoworld.com].
In a paper [33bits.org] set to be delivered at an upcoming security conference, they showed how they were able to map out the connections on public social networks such as Twitter and Flickr. They were then able to identify people who were on both networks by looking at the many connections surrounding their network of friends. The technique isn’t 100 percent effective, but it may make some users uncomfortable about whether they should allow their data to be shared in an anonymous format.

Someone begins watching a basketball game and asks who is winning. You might helpfully answer, “Lakers up 76 to 64.” Imagine if instead you said, “The Lakers are 60% from the field, have 12 rebounds, are 8 of 10 from the line, and the average height of the starting lineup is 6’7.” Sure, these are important statistics, but they certainly do not answer the question. (Inspired by Richard Bejtlich) The person listening would probably think you were trying to be funny, a jerk, or perhaps both.
Yet, this is how the Web security industry responds when businesses ask about the security of their websites. “We identified 21 security defects including eight Cross-Site Scripting and four SQL Injection, we are improving our SDL processes, and most of our programmers have been through security training.” Again, important metrics, but still not answering the most important question — how well defended is a website from getting hacked.

While search engine optimization (SEO) is becoming one of the must do’s for companies that are trying to improve theirsite ranking in search engines like Google and Yahoo, it’s also increasingly becoming a trick of the trade for spammers and malware authors looking to drive traffic to their own infected websites or websites they might have hacked with their malware.
Like any owner of a website, criminals are interested in directing as much traffic as possible to their pages in order to distribute content and increase potential profits. Of course, in their case, the content that they are pushing is malware that aims to use their unsuspecting victim’s computer to send spam, launch denial of service attacks or steal valuable information from other users, such as online banking passwords and credit card numbers. The financial goals are nothing new, but the technique shows the growing sophistication of the spammer and malware author community.

Ask a room full of security practitioners for a list of security settings that’ll make Internet Explorer (IE) safe to use and you’ll either hear laughter or advice to get a new browser like Mozilla Firefox, Opera, Safari or Google Chrome.
Even as Microsoft has worked diligently to improve security in its troubled browser, especially in IE7 and the newly-released IE8, security pros simply don’t trust it. Most have turned to alternative browsers, especially Firefox. Those who have no choice but to use IE have turned to a number of coping mechanisms [cio.com]. Here are ten of the best security settings for Internet Explorer:

It’s been the better part of a decade now since Microsoft got religion about the security of its products, following the release of Bill Gates’s famous Trustworthy Computing memo. In that time, the reliability, security and resiliency of the company’s products has improved greatly, as has Microsoft’s standing in the security community.
