What is Phishious?

Phishious is an open-source Secure Email Gateway (SEG) evaluation toolkit designed for red-teamers developed by the team at https://caniphish.com. It provides the ability to see how various Secure Email Gateway technologies behave when presented with phishing material.

Secure Email Gateways Supported

Why use Phishious?

We're not joking when we say that Phishious is a world first in Secure Email Gateway evaluation. There is currently no other tool available (free or paid) that provides you the ability to scan your phish against an array of Secure Email Gateways. The closest utility is VirusTotal, however this specifically focuses on Malware detection and not Spam/Phish detection.

Through use of Phishious, you'll be able to freely test your phishing material against the world's most popular Secure Email Gateways. This is an invaluable capability as it provides you an indication of how successful your phishing campaign may be.

How does Phishious work?

Phishious exploits a common misconfiguration where many organisations broadcast overly sensitive information in email bounce responses and non-delivery reports. The sensitive information typically comes in the form of original untampered inbound message headers.

By feeding this information into Phishious, it can extract the relevant information and detect when an email is likely to end up in a targets junk folder or be completely blocked by the SEG. When we scale this across many targets, we're able to aggregate this information to provide a holistic view on how various SEGs behave when delivered certain phishing material.

To better understand email bounce attacks and the resulting issues, please read the following Blog Post, watch this BSides Canberra presentation or watch the below introduction video on youtube.

Requirements

Windows 10 Endpoint, Windows Server 2012+ or any Linux system capable of running .NET Core 5.0 (see https://dotnet.microsoft.com/download/dotnet/5.0)

Setup

Phishious is a .NET Core 5.0 MVC Web Application. Accordingly it can be run on Windows using IIS or Linux using Apache as the Web Server. However the simplest way to use Phishious is to clone the project and then Debug it using your favourite IDE (e.g. Visual Studio, Visual Studio Code, Rider, etc.).

How to use Phishious (Automatic)

Documentation is underway. Please check the GitHub project regularly for an update. The automated scan adds an orchestration layer whereby Phishious automatically sends emails, ingests bounce responses and analyses mail headers with only a few clicks from you as the user. The main exercise on you as the user is to identify vulnerable mail receivers.

Phase 1: Identification of Vulnerable Mail Receivers
Phase 2: Phishious Settings
Phase 3: Filter Detonation
Phase 4: Results Analysis
