Microsoft Goes After Clickjacking in IE8



Microsoft has introduced a release client version of its latest browser, Internet Explorer 8 (IE8), and the new iteration of the application includes several security improvements, including a noteworthy attempt to address the emerging problem of clickjacking attacks.

For those who don't recall, clickjacking is a relatively new technique -- first detailed in mid-2008 by researchers Jeremiah Grossman and Robert Hansen, among others -- which involves using widely-available vulnerabilities to take control of an end user's browser.

The idea is that simply by tricking a visitor into arriving at an infected URL, an attacker can manipulate the affected end users' browser session to get them to do just about anything the hackers desires, such as downloading malware, and at the time it was first reported publicly, there were clickjacking vulnerabilities available in just about every major browser, including IE7.

Now, to carry out these kinds of campaigns, obviously the involved attackers need to both subvert Web sites (the more legitimate the better) and have the browser vulnerabilities available that allow them to deliver their code.

While offering few technical details of its methods for stopping clickjacking, Microsoft appears to have not only tried to address the browser-based issues, but also sought out the help of Web site owners to make IE8 less vulnerable to the attacks.

"We've worked closely with people in the security community to enable consumer-ready clickjacking protection. Sites can now protect themselves and their users from clickjacking attacks 'out of the box,' without impacting compatibility or requiring browser add-ons," the company said.

Microsoft said that it also augmented some of its InPrivate features which allow IE users to delete or shield their browsing habits from others who might be using their computers, though it did not offer functional details of that update either.

Now, it will remain to be seen whether or not the features offered in the IE8 RC browser have an effect in preventing clickjacking attacks, but you have to give the guys in Redmond credit. While there will certainly still likely be plenty of vulnerabilities in the browser, as in all browsers, Microsoft has gone from being almost laissez faire when it comes to addressing emerging threats just several years ago, to now, where they are attempting to get out in front of newer attacks.

Love IE or leave it, you have to give them credit for continuing to step up their game.

Tired_Of_It :

Serendipity. Yesterday in some other forum I remarked that Spybot S&D complained that the MSN website was exhibiting Clickjacking when I visited the website the day before yesterday. Wrong, it was actually the NoScript addon in Firefox that did the complaining (graphically, too). Of course, I simply left the MSN website immediately, since that was the 1st time EVER that I'd received a security warning related to Clickjacking. Hmmm, might MS have it there on purpose at MSN so the beta testers could see if the new IE will detect it? Here's what I want before I'll put IE back as my default browser: (1) ability to EASILY turn off and on automatic reload of a website page, as I just hate having my attempt to read something be interrupted; (2) ability to EASILY enable or ignore webpage defined fonts, as many sites simply use way too small of font sizes, (3) ability to EASILY toggle scripting in pages on & off, and with it off by default per website, (4) ability to EASILY stop and/or to disable Flash and other moving graphics, which drive me insane enough to just leave a website I'd otherwise like a lot, and (5) items #1 though 4, above, remembered on a site-by-site basis. But until MS stops telling me what I want, instead of listening to and providing what I want, I have stopped buying Microsoft products and stopped using free ones unless a particular circumstance I wish to access leaves me no other choice. I'm just tired of the disrespect.

H.K. :

As the article states, at least they are on it and trying to improve. Being number 1 certainly has its downsides in this particular business. IE's main flaw has always been its security issues. I've learned more ways to protect myself though with justaskgemalto.com recently.
