Files download information

After 7 years of Contagio existence, Google Safe Browsing services notified Mediafire (hoster of Contagio and Contagiominidump files) that "harmful" content is hosted on my Mediafire account.

It is harmful only if you harm your own pc and but not suitable for distribution or infecting unsuspecting users but I have not been able to resolve this with Google and Mediafire.

Mediafire suspended public access to Contagio account.

The file hosting will be moved.

If you need any files now, email me the posted Mediafire links (address in profile) and I will pull out the files and share via other methods.

P.S. I have not been able to resolve "yet" because it just happened today, not because they refuse to help.  I don't want to affect Mediafire safety reputation and most likely will have to move out this time.

The main challenge is not to find hosting, it is not difficult and I can pay for it, but the effort move all files and fix the existing links on the Blogpost, and there are many. I planned to move out long time ago but did not have time for it. If anyone can suggest how to change all Blogspot links in bulk, I will be happy.


P.P.S. Feb. 24 - The files will be moved to a Dropbox Business account and shared from there (Dropbox team confirmed they can host it )  

The transition will take some time, so email me links to what you need. 

Thank you all

Potao Express samples

http://www.welivesecurity.com/wp-content/uploads/2015/07/Operation-Potao-Express_final_v2.pdf

TL; DR

2011- July 2015

• Aka  Sapotao and node69
• Group - Sandworm / Quedagh APT
• Vectors - USB, exe as doc, xls
• Victims - RU, BY, AM, GE 
• Victims - MMM group, UA gov
• truecryptrussia.ru has been serving modified versions of the encryption software (Win32/FakeTC) that included a backdoor to selected targets. 
• Win32/FakeTC - data theft from encrypted drives
• The Potao main DLL only takes care of its core functionality; the actual spying functions are implemented in the form of downloadable modules. The plugins are downloaded each time the malware starts, since they aren’t stored on the hard drive.

• 1st Full Plugin and its export function is called Plug. Full plugins run continuously until the infected system is restarted

• 2nd Light Plugin with an export function Scan. Light plugins terminate immediately after returning a buffer with the information they harvested off the victim’s machine.

• Some of the plugins were signed with a certificate issued to “Grandtorg”:
• Traffic 

• Strong encryption. The data sent is encapsulated using the XML-RPC protocol.

• MethodName value 10a7d030-1a61-11e3-beea-001c42e2a08b is always present in Potao traffic.

• After receiving the request the C&C server generates an RSA-2048 public key and signs this generated key with another, static RSA-2048 private key .

• In 2nd stage the malware generates a symmetric AES-256 key. This AES session key is encrypted with the newly received RSA-2048 public key and sent to the C&C server.

• The actual data exchange after the key exchange is then encrypted using symmetric cryptography, which is faster, with the AES-256 key

• The Potao malware sends an encrypted request to the server with computer ID, campaign ID, OS version, version of malware, computer name, current privileges, OS architecture (64 or 32bits) and also the name of the current process.

• Potao USB - uses social engineering, exe in the root disguised as drive icon
• Potao Anti RE -  uses the MurmurHash2 algorithm for computing the hashes of the API function names.
• Potao Anti RE - encryption of strings
• Russian TrueCrypt Win32/FakeTC - The malicious program code within the otherwise functional TrueCrypt software runs in its own thread. This thread, created at the end of the Mount function, enumerates files on the mounted encrypted drive, and if certain conditions are met, it connects to the C&C server, ready to execute commands from the attackers.

Ask and you shall receive

I get emails from readers asking for specific malware samples and thought I would make a mini post about it.

Yes, I often obtain samples from various sources for my own research.

 I am sometimes too lazy/busy to post them but don't mind sharing.
If you are looking for a particular sample, feel free to ask. I might have it.

Send MD5 (several or few samples). I cannot provide hundreds/thousands of samples or any kind of feeds. If you ask for a particular family, I might be able to help if I already have it.

Unfortunately, I do not have time to do homework for students and provide very specific sets for malware with specific features as well as guarantee the C2s are still active.  Send your MD5(s) or at least malware family and I check if I have it :) If i have it, I will either send you or will post on the blog where you can download.

If you emailed me in the past and never got an answer, please remind me. Sometimes emails are long with many questions and I flag them to reply to later, when I have time and they get buried or I forget. It does not happen very often but accept my apologies if it happened to you.

Before you ask, check if it is already available via Contagio or Contagio Mobile.

Collection of Pcap files from malware analysis

Update: Feb 19. 2015

We have been adding pcaps to the collection so remember to check out the folder ( Pcap collection) for the recent pcaps.

I had a project to test some malicious and exploit pcaps and collected a lot of them (almost 1000) from various public sources. You can see them in the PUBLIC folder. The credits go to the authors of the pcaps listed in the name of each file. Please visit their blogs and sites to see more information about the pcaps, see their recent posts, and send them thanks. The public pcaps have no passwords on them.

AlienSpy Java RAT samples and traffic information

AlienSpy Java based cross platform RAT is another reincarnation of ever popular Unrecom/Adwind and Frutas RATs that have been circulating through 2014.

It appears to be used in the same campaigns as was Unrccom/Adwind - see the references. If C2 responds, the java RAT downloads Jar files containing Windows Pony/Ponik loader. The RAT is crossplatform and installs and beacons from OSX and Linux as well. However, it did not download any additional malware while running on OSX and Linux.

The samples, pcaps, and traffic protocol information  are available below.

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.

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)

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:
