CapTipper v0.3: http://www.omriher.com/2015/08/captipper-v03-is-out.html  
CapTipper v0.2: http://www.omriher.com/2015/03/captipper-02-released.html  
CapTipper v0.1: http://www.omriher.com/2015/01/captipper-malicious-http-traffic.html  

CapTipper is a python tool to analyze, explore and revive HTTP malicious traffic.  
CapTipper sets up a web server that acts exactly as the server in the PCAP file,  
and contains internal tools, with a powerful interactive console, for analysis and inspection of the hosts, objects and conversations found.

The tool provides the security researcher with easy access to the files and the understanding of the network flow,  
and is useful when trying to research exploits, pre-conditions, versions, obfuscations, plugins and shellcodes.

Feeding CapTipper with a drive-by traffic capture (e.g of an exploit kit) displays the user with the requests URI's that were sent and responses meta-data.  
The user can at this point browse to http://127.0.0.1/[host]/[URI] and receive the response back to the browser.  
In addition, an interactive shell is launched for deeper investigation using various commands such as: hosts, hexdump, info, ungzip, body, client, dump and more...

CapTipper Interpreter
Type 'open <conversation id>' to open address in browser
type 'hosts' to view traffic flow
Type 'help' for more options

CT>
```
The Initialization outputs the conversations found between the client and the server in the following format:

**[ID] : REQUEST URI -> SERVER RESPONSE TYPE (FILENAME) [SIZE IN BYTES]**

**ID**: An assigned Id to the specific conversation  
**REQUEST URI**: The URI that was sent to the server in the GET request  
**SERVER RESPONSE TYPE**: The content-type returned in the server response header  
**FILENAME**: The filename can be a few things:  
  1. Filename attribute given in the response header
  2. Derived from the URI
  3. Assigned by CapTipper if couldn't find any of the above
  
**SIZE IN BYTES**: Response body size

After Initalization, 2 things occur:  
  1. CapTipper creates a pseudo-web server that behaves like the web server in the pcap
  2. An Interpreter is launched
  
The interpreter contains internal tools for further investigation of the objects in the pcap.

Opening a URI in the browser is simply by typing 'open' along with the object id
```sh
CT> open 0
CT> log
[2015-01-09T18:01:28.878000] 127.0.0.1 : GET / HTTP/1.1
```
* None of the commands (Except 'open') actually requires the server to be running. You can turn off the server by typing 'server off' or by adding -s when calling CapTipper.  

Let's see what can we find out without using the browser.  
First, we'll take a bird's-eye view on the traffic by using the command 'hosts'
```sh
CT> hosts

```
It seems that **www.magmedia.com.au** is the compromised site.

By crossing this information and the file types we got in the conversations list, it looks like **grannityrektonaver.co.vu** is the infecting host.

Then what is **pixeltouchstudios.tk** ?

Well, knowing how exploit-kits usually work, this is probably the TDS (Traffic Distribution System) server.  
Let's take a closer look.

We can print the header and the body of the page by typing 'head' and 'body':
```sh
CT> head 2
Displaying header of object 2 (seedadmin17.html):

HTTP/1.1 302 Found
Server: nginx
Date: Thu, 06 Nov 2014 15:02:38 GMT
Content-Type: text/html; charset=iso-8859-1
Content-Length: 354
Connection: keep-alive
Set-Cookie: ehihm=_YocADE3AAIAAgCvjVtU__.vjVtUQAABAAAAr41bVAA-; expires=Fri, 06-Nov-2015 15:03:11 GMT; path=/; domain=pixeltouchstudios.tk
Location: http://grannityrektonaver.co.vu/15c0b14drr9f_1_08282d03fb0251bbd75ff6dc6e317bd9.html

CT> body 2
Displaying body of object 2 (seedadmin17.html) [256 bytes]:

<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html><head>
<title>302 Found</title>
</head><body>
<h1>Found</h1>
<p>The document has moved <a href="http://grannityrektonaver.co.vu/15c0b14drr9f_1_08282d03fb0251bbd75ff6dc6e317bd9.html">here</a>.</p>
<hr
```
* By deafult, the body command returns the first 256 byte, you can change it by typing body 2 1000 - this will print the first 1000 bytes

We see that object 2, returns a *302 redirection* to the infecting host.  
So our hypothesis was probably true.

Let's get more information on object 2 by typing 'info':
```sh
CT> info 2
Info of conversation 2:

 SERVER IP   : 108.61.196.84:80
 HOST        : pixeltouchstudios.tk
 URI         : /seedadmin17.html
 REFERER     : http://www.magmedia.com.au/
 RESULT NUM  : 302 Found
 RESULT TYPE : text/html
 FILE NAME   : seedadmin17.html
 LENGTH      : 354 B
```
The referrer to that page was of course **magmedia.co.au**, but what exactly redirected us?

By looking at the conversations it was probably either the index page or the javascript file.  
Let's have a quick peek at the javascript file (object 1)
```sh
CT> body 1 
Displaying body of object 1 (jquery.js) [256 bytes]:

▼     ♦♥─╜i{#╟ס╢√}~♣X╓t♥═"HJצg♀░→o½%Y▓╡ם║m┘CR║

```
Hmm... What's going on? Let's look at the header
```sh
CT> head 1
Displaying header of object 1 (jquery.js):

HTTP/1.1 200 OK
Content-Encoding: gzip
Vary: Accept-Encoding
Date: Thu, 06 Nov 2014 15:03:41 GMT
Server: LiteSpeed
Accept-Ranges: bytes
Connection: Keep-Alive
Keep-Alive: timeout=5, max=100
Last-Modified: Mon, 10 Feb 2014 12:34:10 GMT
Content-Type: application/javascript
Content-Length: 39562
Cache-Control: public, max-age=604800
Expires: Thu, 13 Nov 2014 15:03:41 GMT
```
The response is gzipped.  
Let's ungzip it:
```sh
CT> ungzip 1
 GZIP Decompression of object 1 (jquery.js) successful!
 New object created: 15
```
Great. a new object was created (15).  
Let's look at it.
```sh
CT> body 15
Displaying body of object 15 (ungzip-jquery.js) [256 bytes]:

/*
Copyright (C) 2007 Free Software Foundation, Inc. http://fsf.org/
*/
function getCookie(a){var b=document.cookie.match(new RegExp("(?:^|; )"+a.replace(/([\.$?*|{}\(\)\[\]\\\/\+^])/g,"\\$1")+"=([^;]*)"));return b?decodeU
RIComponent(b[1]):undefined}(funct
```
So this is the ungzipped version of the JS file.  
Remember, we want to find out what redirected us to the TDS,  
Safe to assume it was an iframe, so let's search for iframes in the new object using the command 'iframes'
```sh
CT> iframes 15
Searching for iframes in object 15 (ungzip-jquery.js)...
 1 Iframe(s) Found!

 [I] 1 : http://pixeltouchstudios.tk/seedadmin17.html
```
There you go, the attacker planted/altered this javascript and made it send the users to the TDS.

Now let's take a look at the files from the infecting server.  
typing 'convs' again will display the conversations:
```sh
CT> convs

```
So what do we have here...  
looks like we have 1 PDF file, 2 SWF files, and 4 EXE files that were probably downloaded by the shellcode.

We can dump all the files to a folder for deeper inspection using the 'dump' function, we can add '-e' to refrain from dumping the EXE files, so we won't accidentally launch them.
```sh
CT> dump all c:\NuclearFiles -e
 Object 0 written to c:\NuclearFiles\0-0.html
 Object 1 written to c:\NuclearFiles\1-jquery.js
 Object 2 written to c:\NuclearFiles\2-seedadmin17.html
 Object 3 written to c:\NuclearFiles\3-15c0b14drr9f_1_08282d03fb0251bbd75ff6dc6e317bd9.html
 Object 4 written to c:\NuclearFiles\4-MetroWest_COVER_Issue2_Feb2014.jpg
 Object 5 written to c:\NuclearFiles\5-3000melbourne.png
 Object 6 written to c:\NuclearFiles\6-3207portmelbourne.png
 Object 7 written to c:\NuclearFiles\7-background1.jpg
 Object 8 written to c:\NuclearFiles\8-00015d76.swf
 Object 9 written to c:\NuclearFiles\9-XykpdWhZZ2.pdf
 Object 13 written to c:\NuclearFiles\13-00015d76.swf
 Object 15 written to c:\NuclearFiles\15-ungzip-jquery.js
```
As you can see, it also dumps the newly created ungzipped javascript file.

We can also examing the files using CapTipper.  
Let's take a look at the first SWF file using 'hexdump'.
```sh
CT> hexdump 8
Displaying hexdump of object 8 (00015d76.swf) body [256 bytes]:

```
Interesting... This file starts with the 'PK' magic bytes, meaning it's actually a zip file, which can be a few things.

Let's take a look at the files inside the zip using the command 'ziplist'
```sh
CT> ziplist 13
 2 Files found in zip object 13 (00015d76.swf):

 [Z] 1 : AppManifest.xaml
 [Z] 2 : xervamanepe4enki.dll
```
Well it seems that this is actually a Silverlight exploit.  
Now we can dump it with it's real extension:
```sh
CT> dump 13 c:\NuclearFiles\Silver_exp.xap
 Object 13 written to c:\NuclearFiles\Silver_exp.xap
```
We can also send the file's md5 hash to VirusTotal to see if it is recognized by any of the Anti-Virus providers, using the command 'vt'.  
These requires a VirusTotal public API key.  
(The file itself isn't sent to VT, only the hash of the file is sent!)
```sh
CT> vt 13
 VirusTotal result for object 13 (00015d76.swf):
