Resources Hub - Email Spoofing - How to Prevent From Email Spoofing Attacks

If you encountered an email that appeared to be from a trusted client, familiar, or company senior but was from a cybercriminal, you experienced an email spoofing attack first-hand. These scammers impersonate people you know to steal information from you. These social engineering attacks have become much more prevalent and effective since they are so believable, so your association and employees must know all about email spoofing to protect your company from email security breaches.

This article will discuss the basics of email spoofing, how to prevent an attack, what tools can ensure email protection and the solution Guardian Digital offers to combat these issues.

What Is Email Spoofing? Why Is It Dangerous?

email spoofing During an email spoofing attack, a malicious actor creates a fraudulent “From” email address to send messages to victims. The cybercriminal forges the email’s header to look like the address is legitimate and trustworthy. As a result, the recipient may not realize the message is from a known sender, and the victim might open links and download attachments that will steal company information and utilize it in all types of email attacks.

Email spoofing can be detrimental and dangerous, as threat actors implement it into phishing attacks and other email scams that cause data loss, fraudulent wire transfers, costly downtime, and severe reputational harm. They can compromise networks, systems, and financial accounts by obtaining the sensitive credentials victims input into a suspicious website, email, or document.

Email-borne cyberattacks from spoofed emails include phishing emails, spear phishing messages, Business Email Compromise (BEC) or Email Account Compromise (EAC) attacks, and even more specific email security issues like ARP, IP, MAC, and DNS spoofing.

How Can I Prevent and Avoid Falling For Email Spoofing Attacks?

Built-in email security features alone can only do a little to authenticate and verify senders to ensure recipients do not interact with spoofed emails. Unfortunately, cybercriminals use such weaknesses to send spam and phishing emails that can mislead viewers regarding the message’s origin. Therefore, preventing email spoofing attacks requires companies to adopt external solutions and tactics to avoid scams.

You can utilize manual methods for checking emails, such as reading the email header, verifying the IP address, and using the sender ID or SPF. However, there are more efficient ways to implement defense-in-depth approaches to email protection behind the scenes so that you do not have to remain active in email authentication. These features and technologies detect and block fraudulent and malicious emails. Employees undergo email security awareness training but can still fall victim to scams and exploits. A safe work environment is vital and requires comprehensive, threat-ready cloud email security software.

What Tools Can I Use To Stop Email Spoofing?

Utilize one of the best practices for email security by adding an email authentication protocol to your cybersecurity tools. As we have discussed, modern attacks can reach through essential cybersecurity platforms, so using SPF, DKIM, or DMARC email authentication helps you to continue daily operations while staying confident that your email security services are preventing phishing and email spoofing issues. These solutions verify sender identities and confirm communication legitimacy so that you can focus on other, more critical tasks.

How Can SPF Records Prevent Email Spoofing?

Sender Policy Framework (SPF) prevents sender address forgery by ensuring that all the emails you send and receive are secure. Oversee all online exchanges to verify that only trusted employees are sending messages, not cybercriminals. SPF enables providers and organizations to use legitimate sources to avoid email domain spoofing issues that could allow unauthorized sources to send fraudulent messages from the server.

What Can DKIM Do to Avoid Email Spoofing?

DomainKeys Identified Mail (DKIM) records TXT through an organization’s Domain Name System (DNS), which provides a safe domain for checking and verifying sender and recipient email addresses. DKIM implements a cryptographic authentication method that uses public keys to ensure that email addresses are accurate and that nobody has altered the messages while they are in transit.

How Can DMARC Protect Against Email Spoofing?

spoofing DMARC email authentication combines SPF and DKIM capabilities into one server that gives clear instructions recipients must follow if emails do not pass the authentication process, meaning they are in junk mail or the trash. Emails passing SPF and DKIM have no evidence of header tampering that could falsify the sender. Any message that passes either SPF or DKIM usually indicates that a sender owns a DNS space, labeling the user as a “Friendly From,” meaning the email address matches the sender. Hence, they are not an email threat.

Use SPF, DKIM, and DMARC email authentication in a comprehensive email security software solution to combat email spoofing and sender fraud effectively. Use an expert provider that understands how to implement these protocols into the most robust email protection service that keeps your sensitive information safe.
