Anti-Spoofing In Email Security

What Is Email Spoofing?

 

Email spoofing is when an email appears to have come from somewhere else other than its true origin. Phishing attacks and spam campaigns use email spoofing because people are more likely to open an email from a legitimate sender.

Spoofing occurs when the attacker pretends to be another entity, such as a person or a business, to commit a crime. The standard spoofing technique involves websites, phone calls, and emails, or more sophisticated approaches like spoofed Domain Name Servers (DNS), IP addresses, or Address Resolution Protocols (ARP).

Cybercriminals use spoofing for illegal purposes such as stealing confidential data, spreading malware, bypassing network security by malicious links or attachments, and performing a denial-of-service attack. Cybercriminals often use phishing emails and spoofing attacks to obtain sensitive information to launch more significant attacks. To steal someone’s identity and assets, hackers use every means of online communication.

If successful, spoofing scams can result in infected computers and networks, security breaches, and potentially significant financial losses. The public reputations of companies can be affected by these threats. Moreover, spoofing that causes traffic to be redirected can disable networks and send unsuspecting users to malicious websites that spread malware and steal information.

What Does A Spoofing Attack Look Like?
A hacker may, for example, design a fraudulent inbound email that appears to come from Paypal. In the email, the user is told that they must click the provided link or else their account will be terminated. This type of attack will contain links that lead them to a webpage that asks the user to verify their identity and change their password immediately. The unsuspecting victim enters valuable information, such as their birth date, Social Security Number, credit card number, and expiration date. In changing their password, they reveal their original Paypal password. The hacker now has access to the user’s PayPal account and can withdraw funds, buy products from online vendors, change the user’s PayPal password to lock them out of their account, and otherwise create havoc for the victim.

PayPal is not the only source for attackers. Any legitimate website with valuable sources can be forged, including your company website. Furthermore, the fake email can appear as though it came from your boss, a human resource executive, your company’s CEO, or a senior executive in the finance department.

Though the bogus email may seem authentic and from a legitimate source, there are always loose ends that you can look for to tell whether the communication is honest or a fraud.

Email Spoofing falls Into The Following Categories:

  • Business Email Compromise (BEC). Employees’ Brand Name (Impersonation attack)
  • Customers / Partners Phish URL Based Attack An email with an URL (Lure attack)
  • Employees / Partners  Look-alike Domain Attack (Impersonation attempts attack type)
  • Employees / Partners Account Takeover / Compromised Account Display Name Deception(Email scam)

Methods To Stop Email Spoofing
A sender verification service allows you to verify the identity of an email address before sending messages to it. An attacker can forge the envelope sender information to trick email servers into accepting the statement as legitimate.

SPF allows you to publish IP address ranges for a specific domain. In SPF, the sender indicates what server he uses to send the email.example.com.SPF works to prevent spoofed emails from being sent to your inbox. Your email provider uses this information to avoid spam.

DKIM allows you to verify that an email came from your domain cryptographically.

DKIM also helps prevent spammers from sending emails that pretend to be from your email service provider by verifying that they came from your domain name. You can check if the two features listed above are enabled on your email service provider’s webmail interface.

Verify Header Using DMARC
DMARC verification is an even more powerful feature than SPF and DKIM to combat “Direct Domain Spamming” and also includes the “Display Name“ and “Brand Impersonations” attacks. Domain Source tie-in authenticates the sender of an email message by using the sending domain name as part of the From header field.

To pass DMARC (Domain-based Message Authentication), an incoming email must pass one of these authentication mechanisms: SPF, DKIM, or DMARC.
