The three default locations for Word are shown below. Further research, however, found that certain trusted locations to which a typical standard user has write privileges could also be used to host DLL-based add-ins.

Files located here containing VBA code are not subject to the standard restrictions imposed by the macro settings, and the code will be executed without warning even if macros are disabled. Key to the work by Kostas and others on persistence using Office templates was the concept of “Trusted Locations”.

The described persistence techniques were tested with Office 2013 running on Windows 7, 8.1 and 10. VBA editor (VBE) add-ins for all VBA using Office products.The following opportunities for Office-based persistence will be discussed, along with the relative benefits and disadvantages of each (from a red team perspective as we’re talking about obtaining persistence): It was inspired by Kostas Lintovois’ similar work which identified ways to persist in transient Virtual Desktop Infrastructure (VDI) environments through adding a VBA backdoor to Office template files (“ One Template to Rule ‘Em All”). This post will explore various opportunities for gaining persistence through native Microsoft Office functionality. Office applications due to this ubiquity present a consistent source of opportunity for persistence mechanisms.

These values come from the rows of the datagridview.One software product that attackers will almost certainly find in the environments that they're targeting is Microsoft Office. The second loop adds values to the corresponding cell in the excel sheet. We run loops for setting the heading in the excel sheet which comes from the column name of the data table.

The Add() method takes the type of template of the workbook as a parameter. We make the instance of the .Application to access the objects. STEP 8: Now we write the code for the button clicking on which the data table would be exported to the excel sheet. The method takes the SQL query as the parameter. So we call the’GetRecords()’ method in the load event of the form. As soon as the form loads, the datagridview is to be populated with the data. STEP 7: The code for the form is shown below. And this method returns the dataTable after executing the SQL query from the database. We developed a method ‘GetRecords()’ in the SQL helper class which takes the SQL query as a parameter. Therefore, it is essential to maintain a connection with the database. Also, we add the connection string in the App.config file so that the datagridview is populated with the data from the table ‘Empl’ existing in the database. This class contains the code for connectivity with the database. It can be installed to avail of the interoperability in the application. STEP 5: Click on Browse to search for dll. Right-click the ‘References’ and click manage NuGet packages.

STEP 4: The other option to get the assembly is by using the Nuget Packages to install the required assembly. This means the assembly is not existing in the Visual Studio STEP 3: As soon as, the Reference Manager opens up, we search for. It enables creating/reading Excel files from a C# application. This assembly enables interoperability between Excel and C#.

STEP 2: Right-click on the ‘References’ in the Solution Explorer to add the dll into the existing form. Drag a datagridview and a button from the toolbox and drop them onto the form. STEP 1: Open a windows form application in Visual Studio. Now let's understand the entire process in an elaborative manner performing each step. For exporting dataTable to Excel we use a dll i.e. Finally, a button would be placed on the form in order to export the dataTable to the excel sheet. For enabling connectivity with the database, we’ll use Ado.net. We will develop windows form with a datagridview which would be getting data from a table existing in the database.
