HashDB IDA Plugin

Malware string hash lookup plugin for IDA Pro. This plugin connects to the OALABS HashDB Lookup Service.

Adding New Hash Algorithms

The hash algorithm database is open source and new algorithms can be added on GitHub here. Pull requests are mostly automated and as long as our automated tests pass the new algorithm will be usable on HashDB within minutes.

Using HashDB

HashDB can be used to look up strings that have been hashed in malware by right-clicking on the hash constant in the IDA disassembly view and launching the HashDB Lookup client.

Settings

Before the plugin can be used to look up hashes the HashDB settings must be configured. The settings window can be launched from the plugins menu Edit->Plugins->HashDB.

Hash Algorithms

Click Refresh Algorithms to pull a list of supported hash algorithms from the HashDB API, then select the algorithm used in the malware you are analyzing.

Optional XOR

There is also an option to enable XOR with each hash value as this is a common technique used by malware authors to further obfuscate hashes.

API URL

The default API URL for the HashDB Lookup Service is https://hashdb.openanalysis.net/. If you are using your own internal server this URL can be changed to point to your server.

Enum Name

When a new hash is identified by HashDB the hash and its associated string are added to an enum in IDA. This enum can then be used to convert hash constants in IDA to their corresponding enum name. The enum name is configurable from the settings in the event that there is a conflict with an existing enum.

Hash Lookup

Once the plugin settings have been configured you can right-click on any constant in the IDA disassembly window and look up the constant as a hash. The right-click also provides a quick way to set the XOR value if needed.

Bulk Import

If a hash is part of a module a prompt will ask if you want to import all the hashes from that module. This is a quick way to pull hashes in bulk. For example, if one of the hashes identified is Sleep from the kernel32 module, HashDB can then pull all the hashed exports from kernel32.

Algorithm Search

HashDB also includes a basic algorithm search that will attempt to identify the hash algorithm based on a hash value. The search will return all algorithms that contain the hash value, it is up to the analyst to decide which (if any) algorithm is correct. To use this functionality right-click on the hash constant and select HashDB Hunt Algorithm.

All algorithms that contain this hash will be displayed in a chooser box. The chooser box can be used to directly select the algorithm for HashDB to use. If Cancel is selected no algorithm will be selected.

Dynamic Import Address Table Hash Scanning

Instead of resolving API hashes individually (inline in code) some malware developers will create a block of import hashes in memory. These hashes are then all resolved within a single function creating a dynamic import address table which is later referenced in the code. In these scenarios the HashDB Scan IAT function can be used.

Simply select the import hash block, right-click and choose HashDB Scan IAT. HashDB will attempt to resolve each individual integer type (DWORD/QWORD) in the selected range.

Installing HashDB

Before using the plugin you must install the python requests module in your IDA environment. The simplest way to do this is to use pip from a shell outside of IDA.
pip install requests

Once you have the requests module installed simply copy the latest release of hashdb.py into your IDA plugins directory and you are ready to start looking up hashes!

Compatibility Issues

The HashDB plugin has been developed for use with the IDA 7+ and Python 3 it is not backwards compatible.

Lets start by defining what SQL injection is, OWASP defines it as: "A SQL injection attack consists of insertion or "injection" of a SQL query via the input data from the client to the application. A successful SQL injection exploit can read sensitive data from the database, modify database data (Insert/Update/Delete), execute administration operations on the database (such as shutdown the DBMS), recover the content of a given file present on the DBMS file system and in some cases issue commands to the operating system. SQL injection attacks are a type of injection attack, in which SQL commands are injected into data-plane input in order to effect the execution of predefined SQL commands."

Which basically means that we can use a simple (vulnerable) input field in our web application to get information from the database of the server which hosts the web application. We can command and control (at certain times) the database of the web application or even the server.

In this article we are going to perform SQL injection attack on DVWA, so let's jump in. On the DVWA welcome page click on SQL Injection navigation link. We are presented with a page with an input field for User ID.

Now lets try to input a value like 1 in the input field. We can see a response from server telling us the firstname and surname of the user associated with User ID 1.

If we try to enter a user id which doesn't exist, we get no data back from the server. To determine whether an input field is vulnerable to SQL injection, we first start by sending a single quote (') as input. Which returns an SQL error.

We saw this in the previous article and we also talked about injection point in it. Before diving deeper into how this vulnerability can be exploited lets try to understand how this error might have occurred. Lets try to build the SQL query that the server might be trying to execute. Say the query looks something like this:

SELECT first_name, sur_name FROM users WHERE user_id = '1';

The 1 in this query is the value supplied by the user in the User ID input field. When we input a single quote in the User ID input field, the query looks like this:

SELECT first_name, sur_name FROM users WHERE user_id = ''';

The quotes around the input provided in the User ID input field are from the server side application code. The error is due to the extra single quote present in the query. Now if we specify a comment after the single quote like this:
'-- -
or
'#
we should get no error. Now our crafted query looks like this:

SELECT first_name, sur_name FROM users WHERE user_id = ''-- -';

or

SELECT first_name, sur_name FROM users WHERE user_id = ''#';

since everything after the # or -- - are commented out, the query will ignore the extra single quote added by the server side app and whatever comes after it and will not generate any error. However the query returns nothing because we specified nothing ('') as the user_id.

After knowing how things might be working on the server side, we will start to attack the application.
First of all we will try to determine the number of columns that the query outputs because if we try a query which will output the number of columns greater or smaller than what the original query outputs then our query is going to get an error. So we will first figure out the exact number of columns that the query outputs and we will do that with the help of order by sql statement like this:

' order by 1-- -

This MySQL server might execute the query as:

SELECT first_name, sur_name FROM users WHERE user_id = '' order by 1-- -';

you get the idea now.
if we don't get any error message, we will increase the number to 2 like this:

' order by 2-- -

still no error message, lets add another:

' order by 3-- -

and there we go we have an error message. Which tells us the number of columns that the server query selects is 2 because it erred out at 3.

Now lets use the union select SQL statement to get information about the database itself.

' union select null, version()-- -

You should first understand what a union select statement does and only then can you understand what we are doing here. You can read about it here.
We have used null as one column since we need to match the number of columns from the server query which is two. null will act as a dummy column here which will give no output and the second column which in our case here is the version() command will output the database version. Notice the output from the application, nothing is shown for First name since we specified null for it and the maria db version will be displayed in Surname.
Now lets check who the database user is using the user() function of mariadb:

' union select null, user()-- -

After clicking the submit button you should be able to see the user of the database in surname.

Now lets get some information about the databases in the database.
Lets determine the names of databases from INFORMATION_SCHEMA.SCHEMATA by entering following input in the User ID field:

' union select null, SCHEMA_NAME from INFORMATION_SCHEMA.SCHEMATA-- -

This lists two databases dvwa and information_schema. information_schema is the built in database. Lets look at the dvwa database.
Get table names for dvwa database from INFORMATION_SCHEMA.TABLES

' union select null, TABLE_NAME from INFORMATION_SCHEMA.TABLES-- -

It gives a huge number of tables that are present in dvwa database. But what we are really interested in is the users table as it is most likely to contain user passwords. But first we need to determine columns of that table and we will do that by querying INFORMATION_SCHEMA.COLUMNS like this:

' union select null, COLUMN_NAME from INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME = 'users'-- -

We can see the password column in the output now lets get those passwords:

' union select user, password from users-- -

Of-course those are the hashes and not plain text passwords. You need to crack them.
Hope you learned something about SQL injection in this article. See you next time.
