Automated Volatility Plugin Generation with Dalvik Inspector

May 23, 2013


In this blog post we will be demonstrating a new feature to the Dalvik Inspector tool, which we are planning on releasing this summer at Black Hat USA. Specifically we have added functionality to the Dalvik Inspector GUI for automatic Volatility plugin creation. To accomplish this, we have developed a simple to use interface, which allows an investigator to select which class members he or she wishes to be included in the plugin output. The generated plugin can then be used in Volatility against future memory samples to provide automatic analysis.

Automatic Plugin Generation

To demonstrate the automatic Volatility plugin generation feature of Dalvik Inspector, we will create a plugin that gives us the url of the Command and Control server of the Chuli malware that we described in a previous post.

First, we open the database that was generated from our memory image by our Volatility plugin in Dalvik Inspector.

Using Dalvik Inspector, we can see that the command and control string is located in the urlstr field of the class,

We navigate to the Home tab and select the new option, “Create New Plugin” and are presented with the following tab:

We first fill out the fields which give our plugin name, description, and the location where we wish the plugin to be saved.

We now must choose the class. Using the dropdown menu, we can see that there are a large amount of classes listed.

Because of this, the interface allows for filtering of classes. Since we know that we’re looking for the class we simply type “services” in the Class Filter box.

This filters the classes, only showing those which contain the word “services”. We can now easily choose our class.

Next, we click the “+” button to add our field. We name the field “CCUrl” and choose the urlstr member.

After clicking OK we can see that the field has been added. We could choose to add, remove, or change the order of the fields that we want to be displayed in the plugin, by using the buttons to the right. However, in this case we only care about the single field.

Clicking “Create Plugin” automatically generates our plugin and saves it at the path we selected.

We add this plugin to Volatility and run it. For future memory dumps, this is the only step required.


We think that this feature of Dalvik Inspector will be very useful and will greatly simplify memory analysis of Android applications. Check back this summer for information about the Dalvik Inspector release!
