PHP hack tools are created and used by attackers to help automate frequent or tedious tasks. During a recent investigation, we came across a hack tool used to simplify the process of sending predefined HTML emails to a list of email addresses.
The tool runs on top of PHPMailer’s library, which handles the connection and sending of the malicious emails.
The hack tool also grants the ability to authenticate to an email address on a remote server.
