Phishing Attack with Spoofed Mail from ScratchMedium

With Social-Engineer Toolkit

In this example, we use brevo as a smtp relay server. The mail received will be of the form username_spoofed@smtp_relay_domain rather than username_spoofed@domain_spoofed, as brevo modifies the domain name for security reasons.

Email Security Checklist

GitHub - hoangcuongflp/Email-Security-Checklist: You’ve hardened your servers, locked down your website and are ready to take on the internet. But all your hard work was in vain, because someone fell for a phishing email and wired money to a scammer, while another user inadvertently downloaded and installed malware from an email link that opened a backdoor into the network. Email is as important as the website when it comes to security. As a channel for social engineering, malware delivery and resource exploitation, a combination of best practices and user education should be enacted to reduce the risk of an email-related compromise. By following this 13 step checklist, you can make your email configuration resilient to the most common attacks and make sure it stays that way.GitHub
