How does Email spoofing Work?

Spammers have been spoofing email addresses for quite a while now. In yester years, they used to get contact records from malware-infected PCs.

How to secure your domain from getting spoofed(Anti-Email spoofing Tool)! Do not let people impersonate your business email

Anti-Email spoofing Techniques

There's no filtering through reality: You have to secure your organization's email. The rise of junk mail has normally reflected the rise of the web. The facts demonstrate that anti-spam methods (anti email spoofing) techniques have developed in advancement, filtering out more undesirable messages.

Spam email is as old as the web, and its development has kept pace with the web’s explosion in popularity. Thus, enter three (genuinely) new tools that are taking the battle against spam messages: DKIM, DMARC and SPF.

How Does SPF Work?

• First, the receiving mail server fetches the sender address of every message it gets.
• Then, it performs a TXT DNS query, checking the SPF entry’s claimed domain.
• After, the data in the SPF entry can be used to authenticate the sender’s server.
• Finally, the sender’s server receives a rejection notice if this authentication fails.

How does DKIM work?

• The final server in the domain infrastructure compares the domain that is in the “From” header. This ensures that it has an entry in its signing table. If not, the process stops.
• Second, a “DKIM-Signature” header is added to the mail message, using the private part of the key in the message content.
• Now, the content of the message is locked and nobody can modify it. Any attempt to do so results in a mismatch with the DKIM header.
• So when the message gets to the receiving server, it creates a TXT DNS query that lets it get hold of the key from the DKIM-Signature field.

Finally, the result of the DKIM header check reveals if a message is real or fake.

How does DMARC work?

• When a message arrives, the mail server looks for a DMARC policy relating to the domain that DKIM and/or SPF use.
• If one or both checks are successful and still with the DMARC policy, then it will be deemed successful. If not, it fails.
• In the event that the check fails, the published DMARC policy will guide further action.
