Sending malicious email as a test

  • 772

I have set up a working SMTP relay together with MailScanner. This SMTP relay is not — and will not be — able to relay email from the outside, only local email.

Is it possible to send a malicious email with the terminal? I have googled around but could not find anything that could answer my question. For example, I want to use:

echo "{malicious-string}" | mail [email protected]

What could the "{malicious-string}" be?

smtp postfix email-server mailscanner

    Use the EICAR test virus. http://www.eicar.org/86-0-Intended-use.html

    echo 'X5O!P%@AP[4\PZX54(P^)7CC)7}$EICAR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H*' | mail

  2. To be sure, you should use the EICAR test virus, and attach it to the email, rather than simply putting it in the body.

    echo -n 'X5O!P%@AP[4\PZX54(P^)7CC)7}$EICAR-STANDARD-ANTIVIRUS-TEST-FILE!$H+H*' > ducklin.docx
echo "Here is 10 million dollars" | mailx -a ducklin.docx [email protected]
