Microsoft365 Device Code Phishing Framework

Solenya - M365 Device Code Phishing Framework

Solenya is a CLI tool which provides a framework to perform M365 device code phishing. As defined in RFC8628, an attacker can perform a social engineering attack by instructing a target to register a malicious application using a device code.

DISCLAIMER: The contributors are not responsible for any malicious use of the tool. The tool is developed for educational purposes and should be used solely by defenders or authorized testers.

Prerequisites

By default, Microsoft allows any user to add new applications to their M365 profile. Below, is a screenshot of a fresh deployment of an Azure subscription.

Installation

The package requires Python 3.7 or higher.

Install latest version from PyPI: pip install solenya

Usage

The CLI tool works with Targets, which are objects contained inside a WorkSpace. The WorkSpace contains the tool's database and other resources, while Targets represent M365 accounts.

Creating a Workspace

The wsp command is responsible for initializing the WorkSpace. The tool leverages an SQLite database to store target information. By default the command will create a folder .sol inside the current current directory.

$ sol wsp c0785c37-5fb1-4ffb-8769-8e9b05ac4e80

Managing Targets

The target command can add additional targets and remove or reset existing ones. The command will automatically reach out to Microsoft Online API and create a user code and a device code, which will both be stored in the database.

$ sol target jaguar rat

The wsp command automatically created a target called default. To switch to a different target use the switch command.

$ sol switch jaguar

User codes and device codes expire after 15 minutes. To reset the device code on the target or delete the target entirely set the following flags.

$ sol target -d default
$ sol target -ra 

Gathering OAuth Access Tokens

The auth command is responsible for authenticating targets registered with the WorkSpace. Run the phish sub command and wait for your targets to enter the user code.

$ sol auth phish -ma

The Oauth2 tokens (access token and refresh token) with access to the target's Office account will be retrieved from the API and saved the WorkSpace database. The access tokens can be refreshed using the refresh command.

$ sol auth refresh -a

Dumping Data

Once the target is authenticated the dump command can be used to dump information from the Graph API.

$ sol dump emails

Exporting Targets

All the data on the targets, such as access token, device code, refresh token, user code and their respective timestamps can be exported using the export command.

$ sol export -a
