Sandbox MIMIng. CVE-2012-0158 in MHTML samples and analysis

Wikipedia

Update - Sept 4, 2013
I added more descriptions and changed NjRat / Backdoor.LV to Vidgrab - in the traffic communications are similar to NjRat/Backdoor;lv but it does not use base64 and sends initial request starting with ...3 (0x01 0x00 0x00 0x00 0x33) followed by null bytes  - it does not start with  lv|

I am still looking for names for a few other backdoors below, so if you recognize them, please let me know. 

Recently, my custom sandbox has been trying to open some Word attachments in a browser because the filetype fingerprint service detected them as MIME HTML files. Browsers are usually the default applications for such types and they did contain the CVE-2012-0158 exploit. A quick Google lookup yielded a May 2013 report from the Chinese company Antiy  "The Latest APT Attack by Exploiting CVE-2012-0158 Vulnerability", which described this new exploit vector.
Antiy noted that these MHTML files evade antivirus and indeed only half of vendors represented on Virustotal detect. However, many companies rely on their automated tools, inline and standalone sandboxes not just Antivirus to determine if the file is malicious.

I checked how these files (file without any extension) were processed by other commercial and open source mailboxes. 3 out of 5 well known commercial and open source mail scan and web sandbox vendors returned no output or informed me that that filetype was not supported. While writing this post, I noticed that Malwaretracker also mentioned the rise in this vector usage in his post on Friday, so I am sure the sandbox vendors are fixing the issue as we speak.

I checked 25 MHTML CVE-2012-0158 files and compared their targets (at least those I could obtain) and payload. The analysis showed a good variety of trojans and predominantly human rights (Tibet, Uyghur) activists. I will post a month worth of these files.

DeepEnd Research: List of malware pcaps, samples, and indicators for the Library of Malware Traffic Patterns

The library of malware traffic patterns have been popular. We found it very useful as well ourselves and we encourage you to send your contributions. I know at some point the spreadsheet will become unwieldy but I personally find it the most easy way (easy sort, search etc)

Currently, most of the samples described have the corresponding samples and pcaps available for download (email Mila @contagio for the password)

such as you see in the links below

Defcon 21 Archives Speaker Materials

Hope it is not a copyright violation and won't cause too much hate. I know Defcon will post better and complete data soon but many / most attendees did not receive the presentation CDs to their great sadness because there were not enough CDs available for all. Many authors and attendees published Defcon and Blackhat presentations online as well -you can track them via Twitter

You can download it here for now. Check Defcon website often, they will post it soon. The list of files of the speaker materials is below. The zip file also includes short stories. Please note that some presentations submitted for the DVD were somewhat / significantly different from what was presented. But better this than nothing, right?

DeepEnd Research: Under this rock... Vulnerable Wordpress/Joomla sites... Overview of the RFI botnet malware arsenal

Exploits directed at Wordpress and/or Joomla content management systems(CMS) have been increasing at a dramatic rate over the past year. Internet blogs and forums are flooded with posts about hacked CMS installations. Popular jargon refers to the attackers as "hackers", but it is generally understood that these mass compromises are being performed via automated scanners and tools. However, we believe that there is not enough coverage of the actual malware involved.

One such infection scheme is essentially the following:

A downloader trojan  (Mutopy  - Win32) (20a6ebf61243b760dd65f897236b6ad3 Virustotal) instructs the infected host to download:
1) Remote File Injector "Symmi" (Win32) 7958f73daf4b84e3b00e008258ea2e7a Virustotal 
2) SDbot (Win32) - aaee52bfb589f6534c4b51e3b144dc08 Virustotal 
3) PHP scripts for injecting into compromised Wordpress sites. Among them a PHP spambot (victimized site owners often get alerted about copious amount of meds and spam porn emanating from their sites). This is also the source of varied links for spam using thousands of various links redirecting to the same sites (e.g. weightloss, work at home scams, or porn sites)

DeepEnd Research - Library of Malware Traffic Patterns

Update May 6, 2013 We added ability to download corresponding samples and pcaps (when available)

Traffic analysis has been the primary method of malware identification and thousands of IDS signatures developed are the daily proof. Signatures definitely help but ability to visually recognize  malware traffic patterns and see the trends when they change has been always an important skill for anyone tasked with network defense. The number of malware analysis blogs and papers is overwhelming and it is difficult to keep track of malware features if you don't have access to a well designed and constantly updated malware database. This started as "personal notes" spreadsheet with GET and   POST requests for different malware families with information from open sources. We decided others might find it useful too.

16,800 clean and 11,960 malicious files for signature testing and research.

Signature and security product testing often requires large numbers of sorted malicious and clean files to eliminate false positives and negatives. They are not always easy to find, but here are some that I have.

Clean documents are collected from various open sources. All the copyright rights belong the the authors of each document and file. You must not use the documents for their content but only as samples of particular file types.

Trojan 'Nap" aka Kelihos/Hlux status update by DeepEnd Research and samples

FireEye posted details about the sleep function found in Kelihos/Hlux (An encounter with Trojan Nap), which is interesting, and indeed is present in some of the samples we saw. The trojan, of course, has many more features, and most of them were documented in previous publications online. This post is a quick update on the state of Kelihos/Hlux botnet, along with  the list of known fast flux domains (1500+) associated with with Kelihos distribution or Command&Control. (current > 2012).  The current and most active name servers are pointing to the ns[1-6].boomsco.com, ns[1-6].larstor.com, and ns[1-6].zempakiv.ru which are also fast flux domains. The double fast flux nature of the botnet makes it very difficult to take down, and sinkholing is a temporary measure. Despite the two large attempts to take it down (Sep.2011 and Mar. 2012), the botnet is definitely on the rise again.

Please read the rest of our post here http://www.deependresearch.org/2013/02/trojan-nap-aka-kelihoshlux-feb-2013.html.
