Fast Mail Bomber via Mailman

English | 简体中文

Fast Mail Bomber via Mailman (also FMB for short) is an email bombing/spamming tool written in php. FMB bombs the target's mailbox by sending bulk emails via mailman services hosted by different providers.

DISCLAIMER: THIS PROJECT IS FOR ACADEMIC PURPOSES ONLY. THE DEVELOPERS TAKE NO RESPONSIBILITY FOR ILLEGAL USAGE AND/OR POTENTIAL HARMS.

Requirements

  • PHP >= 7.2
  • cURL extension support

Features

  • Automatically get mailman servers (providers) from Shodan or import from local files.
  • Multithreading bombing process.
  • 900+ built-in providers & 50,000+ built-in nodes list, providing efficiency.
  • Reliable exception handling mechanism.

Installation

1. Clone this project

You can use git to clone this project or download .zip file from GitHub.

bash
git clone https://github.com/juzeon/fast-mail-bomber.git
cd fast-mail-bomber/

2. Configure

Copy config.example.php to config.php and edit it according to the annotations in the file to suit your needs.

Usage

Concept explanations:

Provider: A mailman server, which usually contains a listinfo page listing all subscription nodes. eg. http://lists.centos.org/mailman/listinfo

Node: A subscription node on a mailman server, which can be used to send subscription confirmation emails to a target. eg. http://lists.centos.org/mailman/subscribe/centos

1. (Optional) Updating Providers from Shodan & ZoomEye or a local file

bash
# Updating providers from Shodan & ZoomEye. Set a Shodan and/or ZoomEye api key in config.php first.
php index.php update-providers

# Importing providers from a local file. There's no restriction on file format/pattern since FMB uses RegExp to match provider urls.
php index.php import-providers 

Duplicate providers will be automatically removed.

2. (Recommand) Updating Nodes from the existing provider list

…

When getting nodes, unavailable providers previously added will be automatically added to a dead list and will not be used.

Duplicate nodes will be automatically removed.

You can also use built-in providers and nodes and skip this step.

3. Starting to bomb

bash
php index.php start-bombing [refined] 

# eg. Use all nodes to bomb an email:
php index.php start-bombing [email protected]

# eg. Use refined nodes to bomb an email:
php index.php start-bombing refined [email protected]

Successful and failed requests will be printed via console. Press CTRL+C to cease the process.

Testing results

I tested FMB's performance when bombing different mail providers once. Here's the results:

Proton Mail: 99.4% into Inbox, 0.6% into Spambox.

Gmail: 83.2% into Inbox, 16.8% into Spambox.

Outlook Mail: 77.1% into Inbox, 22.9% into Spambox.

163 Mail: 100% into Inbox, 0% into Spambox.

QQ Mail: 71% into Inbox, 29% into Spambox.

Zoho Mail: 0% into Inbox, 15.9% into Newsletter, 84.1% into Spambox.

Yandex Mail: 0% into Inbox, 100% into Spambox.

How to prevent being bombed

Because of the mail template used in mailman's default settings, simply add the following text as one of your mailbox's filter rule:

Mailing list subscription confirmation notice for mailing list
