Email Spoofing

Email spoofing involves sending email messages with a forged "from" address. It's a technique used by malicious actors to mislead recipients about the true sender of the message.

A free online tool that you can use for email spoofing is available on emkei.cz.

How It Works

• Simple Mail Transfer Protocol (SMTP): Emails are sent via SMTP, which lacks authentication mechanisms. This absence of authentication allows attackers to manipulate the "from" address.
• Spoofed "From" Address: Malicious actors send emails with a spoofed "from" address, making it appear as if the email originates from a legitimate source.

Impact and Risks

• Deception: Recipients may trust the email due to the familiar "from" address, leading them to take actions they wouldn't otherwise.
• Phishing Attacks: Spoofed emails can trick users into revealing sensitive information, clicking on malicious links, or downloading harmful attachments.
