Weekly Summary : Internet Explorer Vulnerability & New BlackHole 2.0 Pattern

Posted: September 23rd, 2012 | Author: | Filed under: IT Related | Tags: , , , , , | No Comments »

The biggest news for this week is of course related to the recent 0day vulnerability found in Internet Explorer, CVE-2012-4969. The exploit code that has leaked on the same server with the previous Java oday, has been discovered by several researchers and without any delay, it has been ported to Metsaploit framework.

I’ve done a quick writeup on this news earlier, and back then, there is no patch/fixit yet released by Microsoft. So I end up make a reference to MyCERT advisory which recommend users to use EMET and disable Active Script. But recently, Microsoft has released fixit and out of band patch to address this issue. As for now, there is no reported/blogged/twitted information saying that Malaysia has been targeted with this new vulnerability, and there is no Information on this vulnerability has been ported to BlackHole 2.0 as well.

Speaking about BlackHole 2.0, I’ve been seeing new pattern used in BlackHole 2.0 and could bypass most/some detection rules that specifically written based on the initial release of BlackHole 2.0. Thanks to #MalwareMustDie and MalwareDomainList for the brand new and fresh samples. My yara rules updated for both CVE-2012-4969 and BlackHole 2.0++, and MyYaraSIG members may perform a git pull to see the update.

Thats all for this week.

Thanks


CVE-2010-0249 – Aurora IE 0day Exploit :: DEP bypassed

:: Quick update ::

Today, I’ve been working on a video on the Aurora IE 0day exploit PoC that really mimics the original Aurora’s exploit on Google.

However, the original exploit gonna fail if you enable DEP on the machine.

A few minutes back, someone ping and inform me on the new PoC that gonna bypass the DEP. If true, enabling DEP wont protect IE users anymore 😉

But you are still safe if you disable Active Script / JavaScript support for your IE

Here is how you can disable the Active Shit/JavaShit Active Script / JavaScript support in your IE: Advisory

(The facts that I’m gonna talk about are based on my observations)

Back in mid 2007, Mass SQL injection that contain malicious JavaScript started to bring havoc the our cyberspace. But it brought not enough impact to alert and educate the internet user.. Until mid 2008 where another flood of Mass SQL injection happened attacking MS SQL and not so long after that people cant stop talking about 0day in IE, follow by Adobe Flash Player, Adobe Acrobat Reader, Mozilla Firefox and etc..

This clearly shows that the attacking vector is now somehow changed into the client side. This is due to the number of victim on the client side is way more compare to on the server side. Normally the mission of this kind of attack is to force the vulnerable application to crash and execute arbitrary code usually used to download another malicious file and execute it (drive by download). The victim (client) is now part of the attacker’s botnet. Awuuuooo0… (That is how the botnet sound alike.. Hahahaha)

Now in 2009, more and more client side attacks appear abusing IE, Firefox, Thunderbird, Adobe Acrobat Reader, Adobe Flash Player, Microsoft Office Power Point, Microsoft Office Excel, Google Chrome, Apple QuickTime, Foxit PDF Reader, Sun Java Runtime Environment, Adobe Shockwave Player, ActiveX and etc.. The attackers are also aware of the current world issues and trends. That is why we can see some events like H1n1, death of Michael Jackson, independent day, April Fool and many more events have been abuse by the attacker to phish for their victim.

Lately, within thin 2 months, a few mobile phone vulnerabilities have been found. iPhone, Symbian and Windows Mobile were hooked in these exploits. The attackers not only manage to get sensitive data/info from the mobile device, they also able to take control of the mobile device, and from the recent cases, victim’s mobile phones have been used to send spam SMS, MMS and also Email and at the same time, the SMS, MMS and email sent, work as an agent to ‘invite’ more device to be part of the ‘mobile botnet’ society. Awuuuooo0…

Till next time..

P/S: I am writing this entry while I’m working on my presentation slide for next week presentation in one of the organization of standardization and quality. So, I think these issues need to be highlighted as well in my slides. Beside of trends, the impact also need to be highlighted and ‘how bad is the impact could be’ should also be in part of the slide. The after discussing about the trend and impact, please make this as a habit which is to discuss on the prevention and the mitigation part as well. This is important because leaving the presentation stage without prevention or mitigation steps will create FUD to the audience and this is totally not a good practice!
