Websense® Security Labs™ has seen a new zero-day exploit for Internet Explorer (CVE-2013-3897) used in highly targeted, low-volume attacks in Korea, Hong Kong, and the United States, as early as September 18th, 2013. The publication of the vulnerability details ( CVE-2013-3897 ) were shared...

In the previous part of our report, we analyzed the malicious content detected in the domain "rotary-eclubtw.com". We detected the exploitation code for the vulnerability CVE-2012-4792 and analyzed the Flash file which was used to contain the heap spray code and the shell code. In this part we are going to show some of the details that we extracted from the shell code and from behavioral analysis of the malware installed after a successful exploiting attempt. We have also added some details related to the domain name using the WHOIS records and internal data.
Why are waterhole attacks occurring? What is the attackers' objective, both here and in other cases? As we learned from this analysis, the malware is used to steal files from compromised computers, while also enabling monitoring of the user's emails and other activities. We also found suspicious ties to sites potentially targeting high technology suppliers, perhaps in Taiwan. Read on for details of the attack.

Thanks to our ThreatSeeker® technology, it has been possible to detect a domain which we believe is involved in a spear phishing campaign against the users of a Rotary Club online service. The Rotary Club (also called Rotary International) is an organization that provides humanitarian services, encourages high ethical standards in all vocations, and promotes charity actions. Since the Rotary Club is a worldwide organization, each country has a number of local "clubs" for each region and they have also established an online service called "Rotary eClub".
Specifically, we discovered another attempt to exploit the Internet Explorer vulnerability CVE-2012-4792, which was discovered in a "water holing" attack against the USA Council of the Foreign Relations Web site (http://www.cfr.org). The results of our analysis were in accordance with those reported in this blog: apparently another worldwide campaign against several organizations which have in some way attracted the interest of the attackers due to the specific audiences for their sites. In this first part of the analysis, we will report our investigation into the obfuscated code and the exploit code detected. In the second part, we will present the analysis of the unusual mechanism implemented in the shellcode that runs the malware which is installed if the exploit is successful. We will also look at some details of the malware behavior and expose some details behind the involved domains and the infrastructure of this attack.
The suspicious domain in our analysis is "rotary-eclubtw.com", which has apparently been registered to target the Taiwanese users of the Rotary eClub service as shown in the following screenshot:

Firstly, welcome to 2013 and we trust that you had a happy holiday period. As is to be expected, holidays or not, there is no rest for the wicked (be that attacker or defender) and therefore we kick off our 2013 blog with details of CVE-2012-4792, an Internet Explorer zero-day vulnerability.
The Websense® ThreatSeeker® Network has already detected instances of this vulnerability being exploited in the wild, unsurprising given that the exploit is publically available as a Metasploit module, and therefore it is likely that attacks will continue to gain traction.
