Introduction Burp Suite Part IX (Option Tab)

Suite Options

 This tab contains settings to control how Burp handles platform authentication, upstream proxy servers, SOCKS proxy, timeouts, hostname resolution, and out-of-scope requests.

Platform Authentication

 These settings let you configure Burp to automatically carry out platform authentication to destination web servers. Different authentication types and credentials can be configured for individual hosts.

 Supported authentication types are: basic, NTLMv1, NTLMv2 and digest authentication. The domain and hostname fields are only used for NTLM authentication.

The "Prompt for credentials on platform authentication failure" option causes Burp to display an interactive popup whenever an authentication failure is encountered.

Upstream Proxy Servers

 These settings control whether Burp will send outgoing requests to an upstream proxy server, or directly to the destination web server.

You can define multiple rules, specifying different proxy settings for different destination hosts, or groups of hosts. Rules are applied in sequence, and the first rule that matches the destination web server will be used. If no rule is matched, Burp defaults to direct, non-proxied connections.

You can use wildcards in the destination host specification (* matches zero or more characters, and ? matches any character except a dot). To send all traffic to a single proxy server, create a rule with * as the destination host. Leave the proxy host blank to connect directly to the specified host.

For each upstream proxy you configure, you can specify an authentication type and credentials if required. Supported authentication types are: basic, NTLMv1, NTLMv2 and digest authentication. The domain and hostname fields are only used for NTLM authentication.

SOCKS Proxy

 These settings let you configure Burp to use a SOCKS proxy for all outgoing communications. This setting is applied at the TCP level, and all outbound requests will be sent via this proxy.

If you have configured rules for upstream HTTP proxy servers, then requests to upstream proxies will be sent via the SOCKS proxy configured here.

If the option "Do DNS lookups over SOCKS proxy" is enabled, then all domain names will be resolved by the proxy. No local lookups will be performed.

Timeouts

 These settings specify the timeouts to be used for various network tasks. You can specify the following timeouts:

Normal - This setting is used for most network communications, and determines how long Burp will wait before abandoning a request and record that a timeout has occurred.

Open-ended responses - This setting is only used where a response is being processed which does not contain a Content-Length or Transfer-Encoding HTTP header. In this situation, Burp waits for the specified interval before determining that the transmission has been completed.

Domain name resolution - This setting determines how often Burp will re-perform successful domain name look-ups. This should be set to a suitably low value if target host addresses are frequently changing.

Failed domain name resolution - This setting determines how often Burp will reattempt unsuccessful domain name look-ups.

Values are in seconds. If an option is left blank, then Burp will never time out that function.

Hostname Resolution

 These settings enable you to specify mappings of hostnames to IP addresses, to override the DNS resolution provided by your computer.

Each hostname resolution rule specifies a hostname, and the IP address that should be associated with that hostname. Rules can be individually enabled or disabled.

This feature can be useful to ensure correct onward forwarding of requests when the hosts file has been modified to perform invisible proxying of traffic from non-proxy-aware thick client components.

Out-of-Scope Requests

 This feature can be used to prevent Burp from issuing any out-of-scope requests. It can be useful when you need to guarantee that no requests are made to targets that are not in-scope for your current work. Even if your browser makes requests for out-of-scope items, the outgoing requests will be dropped by Burp.

You can enable this feature for the current Target scope. Alternatively, you can define a custom scope using URL-matching rules.

Request and Response Interception in Burp Suite

We have already discussed almost all basic theories about burp suite. Now, Let’s do some practical things with burp suite. You should not jump into practical thing directly without reading Basic theories. If you are wondering for Basic theory then you can visit my previous articles about burp suite which are based in theory. I am providing the link below.

Requirement:

1. Mutillidae

2. Burp Suite

3. Firefox or Iceaweasel

4. Configure Burp suite withfirefox or iceweasel

5. Basic Theories Target Taband Proxy Tab

What we are going to do ?

We will understand how interception work, how we can add a scope in burp suite for particular target and how request and response works.

1. First of all start mysql and apache server for running mutillidae

   Open Terminal

• Type service mysql start and Press Enter
• Type service apache2 startand Press Enter

   Now start burp suite by terminal

• Type burpsuite.jar and Press Enter 

(Click image for large view)

2. Burp Suite has been opened. Go to Proxy Tab then Intercept Sub-tab. There you will see intercept is off.

3. We have seen our interception is off in burp suite so, let’s see what happen when we browse any url in our web browser which is configure with burp suite. We will not use any website to do these testing because that will be illegal so we will use our mutillidae this is our own web server.

Write 127.0.0.1/mutillidaein your web address and Press Enter. Web site responds without any trouble.

4. When we come to intercept sub-tab there are also no web traffic records available.

 We have configured well burp with our browser but still burp is not capturing any web traffic from browser why ?

Very simple answer, because we turned off intercept while browsing the website so, burp could not capture any data. If you are beginner and trying to test any web and your burp is also not getting traffic from the browser then you should look at once your intercept is On or Off.

5. In the Site Map sub-tab we can see which url we have visited it doesn’t matter intercept on or off.

--------------------------------------------------------------------------------

6. Now, Let’s Turn On interception in Intercept sub-tab

7. Go to Proxy Tab then Option Sub-tab. There you will see intercept Client Request and Responsesection you just need to uncheck Match type : URL boxes. (If already unchecked leave this step)

8. Go to Target Tab then Scope Sub-tab. There you will see Include in scope section, you need to delete all the scopes from there if you have added any.

9. Go to your web browser and open 127.0.0.1/mutillidae

10. Go to Burp Suite there you will see it send request to server for response. You need to click on forward for forwarding the request to server so you will get the response from server.

11. Here, We got the response.

12. Go to your web browser, our web browser is still waiting for response.

13. Go to Burp Suite and Click once again on Forward button so, Our web browser should get their response.

14. Here, our web browser got the response.

------------------------------------------------------------------------------

15. Go to Proxy Tab then Option Sub-tab. There you will see intercept Client Request and Responsesection you just need to check Match type : URL boxes. (If already checked leave this step)

16. Intercept should be turn On.

17. Go to your web browser and open 127.0.0.1/mutillidae

18. Interception is On but Burp suite could not get any traffic from web browser.

Why?

Because, We did setup (step 15) burp to get traffic for particular target not for all which are browsed by web browser but we are not getting any traffic because we did not add any target to burp suite yet for getting the traffic.

19. Here we will add a particular url target for getting the traffic on burp. Go to Target tab then Site mapsub-tab and Right Click on the url which one you want to test then Click on Add to Scope.

20. Now we gave burp suite a particular target for testing so if you will browse any other url on same browser it will not effect on burp. I like this method because it do not intercept other websites during your testing. For example I have added 127.0.0.1/mutillidae as a scope means as target. Now I need to search something on google or I am also using facebook while testing for discussion with my team or whatever reason in same browser which is configure with burp suite. If you added a scope 127.0.0.1/mutillidae burp will not show you any traffic for other sites like google search or facebook. It is trace only your target url activity.

As you can see we have added a scope from site map sub-tab. You can also add scope manually by clicking on Add button there you need fill up some details like Protocol, host/Ip range, Prot etc. You can also Enable or Disable your scope by clicking on the check box in include in scope section.

21. Intercept should be On.

22. Go to Web Browser and Open URL 127.0.0.1/mutillidae You will notice it is waiting for response.

23. Burp sends request to server for response. Click on Forward button for getting response.

24. Here, We got response.

25. Go to Web Browser there you will see it is still waiting for response.

26. Go to Burp Suite and click on Forward button so your web browser will response.

27. Here, we got response.

Introduction Burp Suite Part VIII (Comparer Tab)

Burp Comparer is a simple tool for performing a comparison (a visual "diff") between any two items of data. 

Some common uses for Burp Comparer are as follows: 

• When looking for username enumeration conditions, you can compare responses to failed logins using valid and invalid usernames, looking for subtle differences in the responses.
• When an Intruder attack has resulted in some very large responses with different lengths than the base response, you can compare these to quickly see where the differences lie.
• When comparing the site maps or Proxy history entries generated by different types of users, you can compare pairs of similar requests to see where the differences lie that give rise to different application behavior.
• When testing for blind SQL injection bugs using Boolean condition injection and other similar tests, you can compare two responses to see whether injecting different conditions has resulted in a relevant difference in responses.

Word compare - This comparison tokenizes each item of data based on whitespace delimiters, and identifies the token-level edits required to transform the first item into the second. It is most useful when the interesting differences between the compared items exist at the word level, for example in HTML documents containing different content.

Byte compare - This comparison identifies the byte-level edits required to transform the first item into the second. It is most useful when the interesting differences between the compared items exist at the byte level, for example in HTTP requests containing subtly different values in a particular parameter or cookie value.

Introduction Burp Suite Part VII (Decoder Tab)

Burp Decoder is a simple tool for transforming encoded data into its canonical form, or for transforming raw data into various encoded and hashed forms. It is capable of intelligently recognizing several encoding formats using heuristic techniques.

You can load data into Decoder in two ways:

• Type or paste it directly into the top editor panel.
• Select data anywhere within Burp, and choose "Send to Decoder" from the context menu.

You can use the "Text" and "Hex" buttons to toggle the type of editor to use on your data.

Smart Decoding

 On any panel within Decoder, you can click the "Smart Decode" button. Burp will then attempt to intelligently decode the contents of that panel by looking for data that appears to be encoded in recognizable formats such as URL-encoding or HTML-encoding. This action is performed recursively, continuing until no further recognizable data formats are detected. This option can be a useful first step when you have identified some opaque data, and want to take a quick look to see if it can be easily decoded into a more recognizable form. The  decoding that is applied to each part of the data is indicated using the usual colorization.

 Because Burp Decoder makes a "best guess" attempt to recognize some common encoding formats, it will sometimes make mistakes. When this occurs, you can easily see all of the stages involved in the decoding, and the transformation that was applied at each position. You can then manually fix any incorrect transformations using the manual controls, and continue the decoding manually or smartly from this point.

Introduction Burp Suite Part VI (Sequencer Tab)

Burp Sequencer is a tool for analyzing the quality of randomness in an application's session tokens and other important data items that are intended to be unpredictable.

Live Capture

 To perform a live capture, you need to locate a request within the target application that returns somewhere in its response the session token or other item that you want to analyze. You can do this by selecting a request anywhere within Burp and choosing the "Send to Sequencer" option from the context menu. The steps needed to configure the live capture on this request are described below.

Select Live Capture Request

 The live capture request list shows the requests that you have sent to Sequencer from other Burp tools. Select the request that returns the token or other item that you want to analyze.

(Click image for large view)

Token Location Within Response

 Select the location within the application's response where the token appears. The following options are available:

• Cookie - If the response sets any cookies, this option will let you select a cookie to analyze. This is the most common method of passing session tokens to clients.
• Form field - If the response contains any HTML form fields, this option will let you select a form field value to analyze. This method is often used for transmitting anti-CSRF tokens and other per-page tokens to clients.
• Custom location - You can use this option to specify a specific custom location within the response containing the data you want to analyze. This is done using the response extraction rule dialog.
  

Live Capture Options

 These settings control the engine used for making HTTP requests and harvesting tokens when performing the live capture. The following options are available: 

• Number of threads - This option controls the number of concurrent requests the live capture is able to make.
• Throttle between requests - Optionally, the live capture can wait a specified delay (in milliseconds) before every request. This option is useful to avoid overloading the application, or to be more stealthy.
• Ignore token whose length deviates by X characters - You can optionally configure the live capture to ignore tokens whose length deviates by a given threshold from the average token length. This can be useful if the application occasionally returns an anomalous response containing a different item in the location where the token normally appears.
  

Running the Live Capture

 When you have fully configured the live capture, click the "Start live capture" button to begin the live capture. Burp Sequencer will repeatedly issue your request and extract the relevant token from the application's responses.

 During the live capture, a progress bar is shown, with counters of the numbers of tokens, requests, and network errors. The following options are available: 

• Pause / resume - This temporarily pauses, and resumes, the capture.
• Stop - This permanently stops the capture.
• Copy tokens - This copies the currently captured tokens to the clipboard, for use in other Burp attacks (such as in Intruder payloads) or tools.
• Save tokens - This saves the currently captured tokens to file.
• Auto-analyze - If this option is enabled, Burp will automatically perform token analysis and update the results periodically during the live capture.
• Analyze now - This is available when a minimum of 100 tokens have been captured, and causes Burp to analyze the current sample and update the results.

Manual Load

 This function allows you to load Sequencer with a sample of tokens that you have already obtained, and then perform the statistical analysis on the sample.

 To perform a manual load, you first need to obtain your own sample of tokens from the target application through some means, such as your own script or the output from an earlier live capture, or an Intruder attack. The tokens need to be in a simple newline-delimited text format.

 Use the Paste button to paste the tokens from the clipboard, or the Load button to load them from file. The loaded tokens, together with details of the shortest and longest lengths, are displayed for you to sense-check that the sample has loaded correctly.

 To perform the analysis of the loaded tokens, click the "Analyze now" button.

Analysis Options

 The "Analysis options" tab lets you configure how tokens are handled, and which types of tests are performed during the analysis.

Token Handling

 These settings control how tokens are handled during analysis. The following options are available:

• Pad short tokens at start / end - If the tokens produced by the application have variable length, these will need to be padded to enable the statistical tests to be performed. You can choose whether the padding should be applied at the start or the end of each token. In most cases, padding tokens at the start is most appropriate.
• Pad with - You can specify the character that will be used for padding. In most cases, for numeric or ASCII hex-encoded tokens, padding with the "0" character is most appropriate.
• Base64-decode before analyzing - If the tokens are Base64-encoded, you can configure Burp to decode these before analyzing, which will generally improve the accuracy of the analysis.
  

Token Analysis

 These options control the types of analyses that are performed. You can individually enable or disable each type of character-level and bit-level test. Sometimes, after performing an initial analysis with all tests enabled, you may want to disable certain tests to reflect your better understanding of the tokens' characteristics, or to isolate the effects of any unusual characteristics manifested by your sample.

 In the results window, after modifying any of the analysis options you can click the "Redo analysis" button to re-perform the analysis with your new settings, and update the results.

Introduction Burp Suite Part V (Repeater Tab)

Burp Repeater is a simple tool for manually manipulating and reissuing individual HTTP requests, and analyzing the application's responses. You can use Repeater for all kinds of purposes, such as changing parameter values to test for input-based vulnerabilities, issuing requests in a specific sequence to test for logic flaws, and reissuing requests from Burp Scanner results to manually verify reported issues.

The easiest way to start working with Repeater is to select the request you want to work on within another Burp tool (such as the Proxy history or Target site map), and use the "Send to Repeater" option on the context menu. This will create a new request tab in Repeater, and automatically populate the target details and request message editor with the relevant details. You can then modify and issue the request as required.

 When your request is ready to send, click the "Go" button to send it to the server. The response is displayed when this is received, together with the response length and a timer (in milliseconds). You can use the usual HTTP message editor functions to help analyze the request and response messages, and carry out further actions.

Managing Request Tabs

 You can easily manage Repeater's request tabs. You can: 

• Rename tabs by double-clicking the tab header.
• Reorder tabs by dragging them.
• Open a new tab by clicking on the right-most "..." tab.
• Close tabs by clicking the X button in the tab header.
