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/2015/07/30/operation-potao-express/

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.

An Overview of Exploit Packs (Update 25) May 2015


Update May 12, 2015

Added CVE-2015-0359 and updates for CVE-2015-0336

Sunday, March 8, 2015

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.
1. Search the blog using the search box on the right side
2. Search here https://www.mediafire.com/folder/b8xxm22zrrqm4/BADINFECT

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.
