Vulnerable Application

The auxiliary/client/sms/send_text module allows you to send a malicious text/link to a collection of phone numbers of the same carrier.

In order to use this module, you must set up your own SMTP server to deliver messages. Popular mail services such as Gmail, Yahoo, Live should work fine.

Options

CELLNUMBERS

The 10-digit phone number (or numbers) you want to send the text to. If you wish to target against multiple phone numbers, ideally you want to create the list in a text file (one number per line), and then load the CELLNUMBERS option like this:

set CELLNUMBERS file:///tmp/att_phone_numbers.txt

Remember that these phone numbers must be the same carrier.

SMSCARRIER

The carrier that the targeted numbers use. See Supported Carrier Gateways to learn more about supported carriers.

SMSSUBJECT

The text subject.

SMSMESSAGE

The text message you want to send. For example, this will send a text with a link to google:

set SMSMESSAGE "Hi, please go: google.com"

The link should automatically be parsed on the phone and clickable.

SMTPADDRESS

The mail server address you wish to use to send the text messages.

SMTPPORT

The mail server port. By default, this is 25.

SMTPUSERNAME

The username you use to log into the SMTP server.

SMTPPASSWORD

The password you use to log into the SMTP server.

SMTPFROM

The FROM field of SMTP. In some cases, it may be used as SMTPUSER.

Supported Carrier Gateways

The module supports the following carriers:

  • AllTel

  • AT&T Wireless

  • Boost Mobile

  • Cricket Wireless

  • Google Fi

  • T-Mobile

  • Verizon

  • Virgin Mobile

Note: During development, we could not find a valid gateway for Sprint, therefore it is currently not supported.

Finding the Carrier for a Phone Number

Since you need to manually choose the carrier gateway for the phone numbers, you need to figure out how to identify the carrier of a phone number. There are many services that can do this, such as:

Note: If the phone is using Google Fi, then it may appear as a different carrier.

Gmail SMTP Example

Gmail is a popular mail server, so we will use this as a demonstration.

Assuming you are already using two-factor authentication, you need to create an application password.

After creating the application password, configure auxiliary/client/sms/send_text this way:

  • set cellnumbers [PHONE NUMBER]

  • set smscarrier [CHOOSE A SUPPORTED CARRIER]

  • set smsmessage "[TEXT MESSAGE]"

  • set smtpaddress smtp.gmail.com

  • set smtpport 587

  • set smtpusername [USERNAME FOR GMAIL] (you don't need @gmail.com at the end)

  • set smtppassword [APPLICATION PASSWORD]

And you should be ready to go.

Yahoo SMTP Example

Yahoo is also a fairly popular mail server (although much slower to deliver comparing to Gmail), so we will demonstrate as well.

Before using the module, you must do this to your Yahoo account:

  1. Sign in to Yahoo Mail.

  2. Go to your "Account security" settings.

  3. Turn on Allow apps that use less secure sign in.

After configuring your Yahoo account, configure auxiliary/client/sms/send_text this way:

  • set cellnumbers [PHONE NUMBER]

  • set smscarrier [CHOOSE A SUPPORTED CARRIER]

  • set smsmessage "[TEXT MESSAGE]"

  • set smtpaddress smtp.mail.yahoo.com

  • set smtpport 25

  • set smtpusername [USERNAME FOR YAHOO]@yahoo.com

  • set smtppassword [YAHOO LOGIN PASSWORD]

And you're good to go.

Scenarios

After setting up your mail server and the module, your output should look similar to this:

msf auxiliary(send_text) > run

[*] Sending text (16 bytes) to 1 number(s)...
[*] Done.
[*] Auxiliary module execution completed
