What is o365-attack-toolkit

o365-attack-toolkit allows operators to perform an OAuth phishing attack and later on use the Microsoft Graph API to extract interesting information.

Some of the implemented features are :

• Extraction of keyworded e-mails from Outlook.
• Creation of Outlook Rules.
• Extraction of files from OneDrive/Sharepoint.
• Injection of macros on Word documents.

The toolkit consists of several components

Phishing endpoint

The phishing endpoint is responsible for serving the HTML file that performs the OAuth token phishing.

Backend services

Afterward, the token will be used by the backend services to perform the defined attacks.

Management interface

The management interface can be utilized to inspect the extracted information from the Microsoft Graph API.

Features

Outlook Keyworded Extraction

User emails can be extracted by this toolkit using keywords. For every defined keyword in the configuration file, all the emails that match them will be downloaded and saved in the database. The operator can inspect the downloaded emails through the management interface.

Onedrive/Sharepoint Keyworded Extraction

Microsoft Graph API can be used to access files across OneDrive, OneDrive for Business and SharePoint document libraries. User files can be extracted by this toolkit using keywords. For every defined keyword in the configuration file, all the documents that match them will be downloaded and saved locally. The operator can examine the documents using the management interface.

Outlook Rules Creation

Microsoft Graph API supports the creation of Outlook rules. You can define different rules by putting the rule JSON files in the rules/ folder.

Below is an example rule that when loaded, it will forward every email that contains password in the body to [email protected].

Word Document Macro Backdooring

Users documents hosted on OneDrive can be backdoored by injecting macros. If this feature is enabled, the last 15 documents accessed by the user will be downloaded and backdoored with the macro defined in the configuration file. After the backdoored file has been uploaded, the extension of the document will be changed to .doc in order for the macro to be supported on Word. It should be noted that after backdooring the documents, they can not be edited online which increases the chances of our payload execution.

This functionality can only be used on Windows because the insertion of macros is done using the Word COM object. A VBS file is built by the template below and executed so don't panic if you see wscript.exe running.
