Cybercriminals can now utilize sophisticated and undetected tactics for harmful actions thanks to 21st-century technology. A poll conducted in 2020 indicated that 65% of US-based businesses were vulnerable to email phishing and impersonation assaults.

 

If your organization does not implement DMARC, it enables cyberattackers to:

  • Transmit funds from susceptible employees through fraudulent emails while impersonating key officials in your firm.

  • Send bogus bills to your workers and business partners.

  • Use your domain to sell illicit items.

  • Spread ransomware.

  • Impersonate customer service in order to get sensitive customer or partner information.

 

Such scenarios might have long-term ramifications for your company. The hazards are numerous, ranging from jeopardizing the brand's reputation among its partners and customers to the loss of critical corporate information and millions of dollars.

 

Domain Spoofing for the Unversed

Domain spoofing is a typical type of security breach in which a cybercriminal attempts to imitate a company's corporate email domain in order to carry out a variety of destructive operations by faking the sender's address.
The attackers use believable ‘From’ fields in the emails they send out to boost the likelihood of them seeming real and thus opened by recipients. The purpose of domain spoofing is to fool people into believing that the email originates from a reputable source and to influence them into interacting with the fraudulent email that contains harmful links.

 

So how do attackers do it? The answer is simple yet people tend to overlook it. The organization's absence of an email authentication procedure is what enables the success of domain spoofing. Email domains often use SMTP (Simple Messages Transfer Mechanism), a communication protocol that allows mail to be sent through digital systems.

 

It does, however, have limitations, such as the lack of an automatic email authentication system built into it. Cybercriminals use this flaw to spoof email domains and send out bogus emails that claim to come from you. Email spoofing may have serious effects, including the theft of critical corporate secrets or the solicitation of money payments from partners or workers while appearing as top leaders.

 

So, how does DMARC help?

DMARC, which stands for Domain-based Message Authentication Reporting and Conformance, is an email authentication mechanism designed to protect company domains and brands from spoofing attacks. To ensure that only genuine emails are delivered to end users, DMARC requires the deployment of a combination of SPF and DKIM email authentication methods.

 

Without DMARC, all emails sent from your company's email domain are sent to the recipient's inbox without any security checks or validation. However, using DMARC, the receiver's Mail Transfer Agent (MTA) pulls up the domain name's SPF, DKIM, and DMARC records to authenticate the sender. The email is delivered to the recipient's inbox once the sender has been validated or authenticated.


By authenticating all emails sent from your domain, you not only prevent imposters from using your domain name to conduct harmful actions and launder money, but you also increase email deliverability and help your customers and partners react to your emails more quickly.

 

Implementing email authentication techniques in your corporation allows you to keep up to speed on evolving attacker strategies, safeguard your corporate databases, and avoid financial or information losses.
