Protect Your Domain From Email Spoofing
Email doesn’t come with anti-spoofing measures. Unfortunately, spoofing is so easy, almost anyone can do it. Discover how to protect your domain from attacks with DMARC
What Is Email Spoofing?
Email spoofing is one of the most common cybercriminal activities. It’s also a gateway to dangerous hacking activities such as phishing and spear phishing. Spammers use spoof emails as a form of digital forgery, mimicking a trusted source and entice recipients to click a link, open an attachment, or take any number of actions that compromise the security of their device by downloading spyware or other malicious software.
Detecting Fraudulent Email
In a spoofed email, the email “from” address impersonates a trusted sender. However, the real sender’s domain will be different from the impersonated email domain. Early spoofed emails were easier to spot as they often contained suspicious instructions, attachments, links, vague salutations such as “Dear Customer”, as well we grammatical errors. However, bad actors are improving their email spoofing techniques and fewer obvious errors. Often, members of an organization are spoofed by a sender impersonating the CEO or CFO of their organization during a targeted attack. Instructions may include opening an attachment, clicking a link, or wiring money to an unfamiliar account. You should never open suspicious attachments or click unfamiliar links.
Protecting Your Domain
The solution to email spoofing attacks is an email authentication standard called DMARC. Mailbox providers like Google, Microsoft and Yahoo use DMARC technology to protect against spoof email.
Organizations sending mail from a domain not protected by DMARC are completely vulnerable to attack. Spoofing is so simple that almost anyone can do it. And, when successful, the vulnerabilities created can be devastating.
DMARC picks up where other email authentication technologies like SPF and DKIM leave off — offering full protection against spoofing without requiring any action from the end user in order to be effective. Email senders using DMARC now have the capability to automatically reject suspicious email, so spoofed email never gets delivered.
Operating Without DMARC Protection: The Risks
- If you click a link or open an attachment in a spoofed email you may be exposed to malware or identity theft.
- Without DMARC protection, your domain could be spoofed for months before anyone would notice — enough time to create enormous vulnerability to hackers.
- You risk destroying trusted relationships with customers who are receiving spoofed email from your compromised domain.
