How to Prevent Email Spoofing with DKIM, DMARC & SPF

Cybercriminals often use spoofing as part of a phishing attack. Phishing is a method used to obtain data by faking an email address and sending an email that looks like it is coming from a trusted source that could reasonably ask for such information. The goal is to make victims click on a link or download an attachment that will install malware on their system.

Spoofing is also related to domain impersonation, in which an email address that is similar to another email address is used. In domain impersonation, an email may come from an address such as , while, in a spoofing attack, the fake sender’s address will look genuine, such as

What Does It Mean My Email Is Being Spoofed

Email spoofing is when the sender of an email, typically spam, forges the email header “From” address so the email being sent appears to have been sent from a legitimate email address that is not the spammers own address.

They do this for a couple of reasons:

  • To trick spam filters into allowing the email through by using a reputable email address. This would be one way your friends and family would see spam emails from you in their Inbox, rather than their spam folder.
  • To prevent the bounce back emails from being received in the spammer’s own inbox. Spammers may send their spam out to thousands of email addresses, and inevitably a lot of those emails are going to bounce. Since spammers don’t want to receive hundreds of bounce back messages, this prevents that from happening.
  • Email spoofing is more common with email accounts that are not actively used. If the account is used on a daily basis, there’s a higher chance that your account might have been compromised by malware or a virus.

    While there is no fool-proof way to prevent either type of abuse to your email address, you could adopt some “best practices” when it comes to your email security:

    Email Spoofing: What Is It

    Email spoofing is when a fraudster forges an email headers From address to make it appear as if it was sent by someone else, usually a known contact like a high-level executive or trusted outside vendor.

    This kind of identity deception is widely used in phishing and spam attacks to help boost the open rate and efficacy of malicious emails. In many email attacks, embedded links lead to phishing sites designed to swipe sensitive information or login credentials from recipients. Others contain malware-laden attachments, or employ social engineering to bamboozle well-researched targets out of money in spear-phishing or business email compromise scams.

    These crimes often involve the use of lookalike domains and domain spoofing, though display name spoofing is the most common method of identity deception in email-based impersonation scams, employed in two-thirds of all attacks.

    Typical scenarios include fraudsters impersonating an employee in emails sent to payroll seeking a change in direct deposit details before the next pay period, or posing as a senior executive requesting W2 information on employees. Increasingly, they involve cybercriminals masquerading as a trusted outside vendor.

    Protect Your Organization From Email Spoofing

    Email spoofing is a highly damaging and increasingly frequent form of cyber fraud. In a spoofing email attack, a cybercriminal sends an email with a “From:” address that appears to be from a source the recipient trusts: a colleague, a friend, an executive or a well-known vendor our company. The email will typically ask the recipient to perform an action that eventually gives attackers access to networks, systems or financial accounts. Email spoofing is usually used in phishing and spear-phishing attacks, and in an impersonation attack where an email may seem to be from a CEO or CFO who is asking the recipient to wire money to an account that turns out to be fraudulent.

    Defending against email spoofing requires a multilayered approach to security. Users, often the weakest link, must be empowered with knowledge and best practices that can help them know how to spot phishing and email spoofing attacks. But because it’s impossible for users to identify every email spoofing attempt every time, organizations need state-of-the-art defenses that can automatically recognize and warn users about suspicious email.

    What Is Email Spoofing Here Are 9 Tips To Outsmart It

    Email spoofing is when a scammer uses a familiar company or individual to trick recipients into thinking that the email theyve received is from a trusted source. Typically, these emails have bad intentions and can lead to personal and professional security issues.

    These days, its common for spoofers to fabricate sender addresses to trick recipients into opening emails maybe even replying.

    Most spoofed emails are simply a nuisance. However, more and more malicious varieties are popping up, and these can cause serious problems even real security threats, in some cases.

    Read on to discover everything you need to know about email spoofing and the different ways you can protect yourself.

    Is Caller Id Spoofing Illegal

    How to Spot a Spoofed Email

    Telemarketers who make calls to Canadians are required to accurately identify themselves and their client. Telemarketers who use technology to spoof their Caller ID information with inaccurate, false or misleading information violate this requirement. Each violation of the Unsolicited Telemarketing Rules can lead to fines up to $1,500 per violation for an individual and $15,000 per violation for a corporation.

    Spoofing Via Legitimate Domains

    Suppose the attacker is aiming at higher believability. In that case, he may also use a trusted email address in the From header, such as Customer Support Specialist . This means both the display name and email address will show misleading information.

    This attack doesnt need to hijack the account or penetrate the targeted companys internal network. It only uses compromised Simple Mail Transfer Protocol servers that permit connections without authentication and allow you to manually specify the To and From addresses. Using shodan.io, we can identify 6,000,000 SMTP servers, many of which are guaranteed to be vulnerable. Besides, the attacker can always set up a malicious SMTP server himself.

    The situation is dire because many enterprise email domains arent using any countermeasures for verification. Still, there are some techniques that you could use to protect your domain more on that later.

    Spoofing Via Lookalike Domains

    Suppose a domain is protected, and domain spoofing isnt possible. In that case, the attacker is most likely going to set up a lookalike domain. In this type of attack, the fraudster registers and uses a domain that is similar to the impersonated domain, e.g.@doma1n.co instead of@domain.co. This change could be minimal enough not to be noticed by an inattentive reader. Its effective because when exactly was the last time you bothered to read an email header?

    Using a very similar domain, which also bypasses spam checks due to being a legitimate mailbox, the attacker creates a sense of authority. It might be just enough to convince its victim to reveal their password, transfer money, or send some files. In all cases, email metadata investigation is the only way to confirm whether the message is genuine. However, its sometimes plain impossible to do on the go, especially with smaller smartphone screens.

    Analyze The Email Header

    Check the ‘From’ email address, not just the display name. Whenever you get an email, hover over the contact name and look at the actual email address. They should match or be pretty close.

    For the below points, you need to go to the original source of the email and then look for the following in the email header:

    • Return path
    • Received file
    • Reply-To header

    The email address should match the original email address in each field. If it doesn’t, then email is likely to be spoofed.

    What You Can Do About Self

    What is Email Spoofing &  How to Protect Yourself?

    Unfortunately, theres no way to prevent spammers from spoofing your address. Hopefully, the email system you use implements both SPF and DMARC, and you wont see these targeted emails. They should go straight to spam. If your email account gives you control of its spam options, you can make them more strict. Just be aware you might lose some legitimate messages, too, so be sure to check your spam box often.

    If you do get a spoofed message from yourself, ignore it. Dont click any attachments or links and dont pay any demanded ransoms. Just mark it as spam or phishing, or delete it. If youre afraid your accounts have been compromised, lock them down for safety. If you reuse passwords, reset them on every service that shares the current one, and give each a new, unique password. If you dont trust your memory with so many passwords, we recommend using a password manager.

    If youre worried about receiving spoofed emails from your contacts, it might also be worth your time to learn how to read email headers.
