It’s that time of the year! The moment when we look back, and reflect on Webroot’s Threat Blog most popular content for 2012.
Which are this year’s most popular posts? What distinguished them from the rest of the analyses published on a daily basis, throughout the entire year?
Let’s find out.

A new zero-day vulnerability exploit has been identified in Microsoft’s Internet Explorer web browser versions 9 and below running on Windows XP, Vista and 7. Internet Explorer 10, which comes bundled with Windows 8, is not affected. The exploit could allow remote execution of malicious code from compromised websites. Continue reading

End and corporate users (and especially Pizza eaters), beware!
Cybercriminals are currently spamvertising hundreds of thousands of emails, impersonating FLORENTINO`s Pizzeria, and enticing users into clicking on a client-side exploits and malware serving link in order to cancel a $169.90 order that they never really made.

From DIY (do-it-yourself) exploit generating tools, to efficient platforms for exploitation of end and corporate users, today’s efficiency-oriented cybercriminals are constantly looking for ways to monetize hijacked web traffic. In order to do so, they periodically introduce new features in the exploit kits, initiate new partnerships with managed malware/script crypting services, and do their best to stay ahead of the security industry.
What are some of the latest developments in this field?
Meet Sweet Orange, one of the most recently released web malware exploitation kits, available for sale at selected invite-only cybercrime-friendly communities.
What’s so special about Sweet Orange? Does it come with customer support? What client-side exploits is it serving? How are the Russian cybercriminals behind it differentiating their underground market proposition in comparison with competing kits, such as the market leading Black Hole web malware exploitation kit?
Let’s find out.

According to a newly released report from NSS Labs, Microsoft’s Internet Explorer 9 outperforms competing browsers in protecting against socially engineered malware.

Security researchers from Webroot have intercepted two currently live client-side exploits serving malware campaigns that have already managed to infect over 20,000 PCs across the globe, primarily in the United States. Based upon detailed analysis, it can be concluded that both campaigns are launched by the same cybercriminal.

Who said there’s such a thing as a trusted Java applet?
In situations where malicious attackers cannot directly exploit client-side vulnerabilities on the targeted host, they will turn to social engineering tricks, like legitimate-looking Java Applets, which will on the other hand silently download the malicious payload of the attacker, once the user confirms he trusts the Applet.
Let’s profile a DIY (do-it-yourself) malicious Java Applet generator currently available for download at selected cybercrime-friendly online communities:

Security researchers from Webroot have intercepted a currently active, client-side exploits-serving malicious campaign that has already managed to infect 18,544 computers across the globe, through the BlackHole web malware exploitation kit.
More details:
As a follow-up to the Blackhole Exploit posting, I thought I would share one aspect of my job that I truely enjoy: Discovery.
While investigating some active urls being served up via a blackhole kit, I noticed something quite odd, as I would end up on sites that had malicious code injected into their webpages.
Once the redirection to the blackhole kit was initiated, I saw the usual exploits taking place, first being Internet Explorer and Adobe Flash, then onto Adobe Reader and Java.
This time, the kit didn’t stop there. Internet Explorer proceeded to launch Windows Media Player. Since I had never used it on this test machine, the Windows Media Player install sequence initiated, causing the windows media player setup screen to appear in order to finalize its installation.
I became curious as to what Windows Media Player is being used for. Unfortunately in this case, I couldn’t see where any files were called down to the machine and did not have any type of network analyzer running.

Several weeks back, I was presented with a group of snapshots from an active BlackHole Exploit Kit 1.2 Control Panel.
As with other toolkits I’ve seen in the wild, this one has all the makings of some real bad medicine. The authors have yet again gone to the trouble of making this toolkit incredibly easy to use and widely available for a price. Just a little unsavory web hosting in a country with few or no diplomatic relations and off to the races they go.
It appears this toolkit is configurable in both Russian and English, making one wonder its true origins.
I’ve slowly tracked URLs accompanying this toolkit and watched it dish out some very widely undetected malware, such as:
Information Stealing/Banking Trojans:
SpyEye
Zeus
Carberp
Mebroot Rootkit
Another more popular rootkit we’re seeing very widely on the Webroot realtime watch is: vSirefef.B/Zero-Access.
BlackHole toolkit preys on only two items in a user’s machine:
1) Unpatched operating system exploits
2) Internet browsers, add-in and plugin exploits such as Adobe and Java Software
Here are some of the known exploits the kit can execute on a victim’s machines.
Windows Operating Systems:
CVE-2010-1885 HCP (Microsoft Windows Help and Support Center in Windows XP and Windows Server 2003)
http://technet.microsoft.com/en-us/security/bulletin/MS10-042
CVE-2006-0003 IE MDAC
http://technet.microsoft.com/en-us/security/bulletin/ms06-014
Adobe Software:
CVE-2008-2992 Adobe Reader util.printf
CVE-2009-0927 Adobe Reader Collab GetIcon
CVE-2007-5659 Adobe Reader CollectEmailInfo
Java Software:
CVE-2009-1671 Java buffer overflows in the Deployment Toolkit ActiveX control in deploytk.dll
CVE-2010-0840 Java trusted Methods Chaining Remote Code Execution Vulnerability
CVE-2010-0842 Java JRE MixerSequencer Invalid Array Index Remote Code Execution Vulnerability
CVE-2010-0886 Java Unspecified vulnerability in the Java Deployment Toolkit component in Oracle Java SE
CVE-2010-1423 Java argument injection vulnerability in the URI handler in Java NPAPI plugin
The basic view the bot controller has is of the statistics page, which should indicate why I listed some of the expoits this toolkit is using. Not surprisingly, for as young as the kit is, you can see that both the Java and Adobe softwares are exploited far more than any others.
I’m sure some think they are safe using a browser other than Internet Explorer but it appears from this image there isn’t alot of difference in how this toolkit has behaved between the three browsers it’s touched.
As the authors have made this toolkit easy to use, they have also made it easy to maintain a low detection rate on the binaries by using an antivirus scanning service which does not share any binaries collected with the AV industry.
The easy-to-read statistics page make it simple for the controller to view and monitor how well or poor the current bot is doing – how many operating systems it’s infected, what type of operating systems were infected, and in which countries they’re located.
