Email spoofing is a method used in spam and phishing campaigns to fool people into believing a communication came from someone or something they know or can trust. Spoofing attacks include the sender forging email headers so that client software shows the forged sender address, which most users accept at face value. Users perceive the bogus sender in a message unless they study the header more thoroughly.

They are more likely to trust a name they recognize. As a result, they will click on fraudulent sites, open virus attachments, submit critical information, and even wire business dollars.

Because of the way email systems are constructed, email spoofing is possible. The client application assigns a sender address to outgoing messages; outgoing email servers have no means of knowing whether the sender address is authentic or faked. Antimalware software and recipient servers can assist in detecting and filtering fraudulent communications.

How does Email Spoofing work?

Phishing may take various forms, but email spoofing is a popular one among hackers. The idea is to trick consumers into thinking an email is from a certain person or business. However, it contains harmful purposes, such as the installation of malware or the acquisition of sensitive personal information.

An email spoofing effort, like a bait that looks like food to a fish, appears nice at first glance, but it’s packed with hazardous hooks. Email spoofing occurs because the Simple Mail Transfer Protocol (SMTP) lacks a mechanism for authenticating a sender before a message is delivered. As a result, attackers seek mail servers with open SMTP ports and no email authentication techniques.

Types of Email Spoofing 

  1. Emails impersonating a person

These are emails that appear to be from someone you know, such as a friend or family member, a business associate, or a coworker. You’ve probably heard of, and perhaps even received, a questionable email from your boss or HR asking for something unusual or including an unusual attachment.

This form of email fraud poses a significant cybersecurity risk to firms worldwide. It does, however, target individuals within your business and should not have an influence on your brand’s reputation or your consumers.

  1. Email spoofing that impersonates a brand

This sort of spoofing is the fabrication of false emails that look to originate from a well-known organization that users trust and expect to see in their inboxes. Scammers fake information in email headers to make it appear as though the sender is a well-known business to the receiver.

These faked emails frequently direct recipients to a fake web page where they are requested to input account login credentials or sensitive information such as credit card details. Unlike phishing efforts that mimic persons, those that spoof brands may send comparable bogus emails to a broad number of your consumers. This can eventually lead to a tarnished brand reputation and a drop in email engagement.

How does Email Spoofing affect Brand Reputation?

An organization isn’t liable if attackers impersonate the brand. Unless it is connected to a data breach, companies can’t be sued for email spoofing. However, that doesn’t mean there’s no need to worry about it, and it doesn’t mean you shouldn’t try to stop it either. Attacks using your company’s identity to commit fraud can have a direct impact on your business and your email marketing efforts. While your brand isn’t to blame for email spoofing, your subscribers and customers may not see it that way.

Subscribers who have been duped by email spoofing will, at the very least, think twice the next time they receive an email from you in their inbox. If this happens to a large enough number of individuals, it will have an impact on your engagement rates and the efficacy of email as a marketing tool.

When Frost & Sullivan polled thousands of information security executives, they discovered that 71 percent indicated minimizing brand damage was their top concern. To do this, email marketers and cybersecurity teams may collaborate to use email authentication techniques to prevent email spoofing.

The Role of Email Authentication to prevent Email Spoofing 

The most effective strategy for companies to defend their reputation from email spoofing is to adopt technology that assists mailbox providers in verifying the sender’s identity. There are four primary email authentication systems that compensate for SMTP’s shortcomings. Each one is a record or policy that is configured on the sender’s DNS (domain name server) from which email is sent.

  1.   SPF (Sender Policy Framework)

An SPF record is published on the DNS so that receiving mail servers may verify that the name in the from field matches what is mentioned in the record. SPF also includes a list of IP addresses that are permitted to send emails on behalf of the domain.

  1. DMARC (Domain-based Message Authentication Reporting, and Conformance)

DMARC is a customizable policy that checks for both SPF and DKIM on a sender’s DNS record. The policy specifies what mailbox providers should do with email from a sender when authentication fails. DMARC will advise the mailbox provider to ignore the policy, quarantine the email by forwarding it to spam or reject/block the email from being delivered.

  1. DKIM (DomainKeys Identified Mail)

The DKIM technique employs a public DNS key that corresponds to a private encrypted key, or digital signature, that is attached to the email. This aids mailbox providers in detecting counterfeit sender information in email headers. DKIM signatures, like passwords, must be changed on a regular basis.

  1. BIMI (Brand Indicators for Message Identification)

BIMI is a relatively recent email authentication technology that can assist subscribers in detecting email spoofing attempts. When BIMI is properly configured, a brand’s logo will show next to messages in the inbox. Senders must additionally have a valid DMARC policy set to quarantine or reject in order for BIMI to function.

Email authentication might appear to be difficult and sophisticated. It is critical for marketers to participate, but it is also probable that you will want support from IT, security teams, and your email service provider (ESP) in order for these entries to be appropriately published on the DNS.
