<p><b>Lesson Plan Title:</b> How to Perform JSON Injection </p>
</div>
<p><b>Concept / Topic To Teach:</b> </p>
This lesson teaches how to perform JSON Injection Attacks.
<br>
<div align="Left">
<p>
<b>How the attacks works:</b>
</p>
JavaScript Object Notation (JSON) is a simple and effective lightweight data exchange format. JSON can be in a lot of forms such as arrays, lists, hashtables and other data structures.
JSON is widely used in AJAX and Web2.0 application and is favored by programmers over XML because of its ease of use and speed.
However, JSON, like XML is prone to Injection attacks. A malacious attackers can inject the reply from the server and inject some aribtrary values in there.
</div>
<p><b>General Goal(s):</b> </p>
<!-- Start Instructions -->
* You are travelling from Boston, MA- Airport code BOS to Seattle, WA - Airport code SEA.<br>
* Once you enter the three digits code of the airport, an AJAX request will be executed asking for the tickets price.<br>
* You will notice that there are two flights available, an expensive one with no stops and another cheaper one with 2 stops.<br>
* Your goal is to try to get the one with no stops but for a cheaper price.

<div align="Center">
<p><b>Lesson Plan Title:</b> How to Perform Silent Transactions Attacks. </p>
</div>
<p><b>Concept / Topic To Teach:</b> </p>
This lesson teaches how to perform silent transactions attacks.
<br>
<div align="Left">
<p>
<b>How the attacks works:</b>
</p>
Any system that silently processes transactions using a single submission is dangerous to the client.
For example, if a normal web application allows a simple URL submission, a preset session attack will
allow the attacker to complete a transaction without the users authorization.
In Ajax, it gets worse: the transaction is silent; it happens with no user feedback on the page,
so an injected attack script may be able to steal money from the client without authorization.
</div>
<p><b>General Goal(s):</b> </p>
<!-- Start Instructions -->
* This is a sample internet banking application - money transfers page.<br>
* It shows below your balance, the account you are transferring to and amount you will transfer.<br>
* The application uses AJAX to submit the transaction after doing some basic client side validations.<br>
* Your goal is to try to bypass the user's authorization and silently execute the transaction<br>
