Case Scenario:

“Recently, a guy complained that someone is sending nasty emails to his friend from his email address. Upon complete investigation, investors found that spammers were sending emails to his all friends.  The primary intention of the email spammer was to ask for money by sending a link and/or click here to pay.

What is Spoofing Attack?

In email accounts fraud, there are various techniques that attackers choose to perform phishing campaigns. One of the widely chosen way to fraud by attackers is email spoofing. Email spoofing is a synonym for Phishing. In this blog, we will discuss in detail what does email spoofing mean as well as how to prevent email spoofing attacks.

Email Spoofing Meaning in Computer Security

Email spoofing is the fabrication of an email  header so that the email appears to have come from the actual source,  however it is actually originated by someone else from somewhere. Email spoofing is a popular strategy which is used to trick the recipient to theft their sensitive information. Moreover, the spoofed emails are just a problem that needs an action apart from removal and sometimes gives rise to a real security threat.

For example, a spoofed message may pretend to be from a well-known company, asking the receiver to provide his personal information such as credit card numbers, passwords, etc. or asking to click on a phishing link.

How does Email Spoofing Attack Work?

Many of you might have come cross with an instance wherein an email message from your friend looks strange or might be annoying too. It doesn’t mean that someone hacked your friend’s email but instead attackers spoofed the email address that is actually not a tough task to do. Here’s how they do:

Email spoofing is feasible in nature because the SMTP (Simple Mail Transfer Protocol) should not be considered for providing address authentication. It is the flaw in SMTP through which spammers can perform spoofing easily.

Reasons for Email Spoofing

Email spoofing mostly known for phishing, there may be several reasons behind email spoofing. It can be used to:

  • Hide identity: Through email spoofing, senders can easily hide his true identity. It can be done by registering anonymous email addresses.
  • Avoid Blacklists: If the sender sends spam emails, it may be blacklisted. To avoid this problem a simple solution is to switch email addresses by spoofing. 
  • Pretending to be someone else: To ask for personal information or to access personal resources, the sender pretends to be someone whom the recipient knows.
  • Identity theft: In order to ask financial accounts from victims, spammers may send+ emails using someone’s name to commit identity theft.

How to Prevent Email Spoofing Attacks?

To prevent email spoofing and spamming, the following practices should be considered:

  • Keep the antivirus in system up to date to prevent email spoofing attacks.
  • Avoid sharing private or financial information through emails.
  • Turn on the spam filters from the settings option to stop email spoofing or other scams.
  • Do not directly click on suspicious links.
  • Avoid downloading suspicious attachments.
  • Never enter any personal information by clicking on insecure links.
  • Perform reverse IP look-ups to know the real sender.
  • Analyze email accounts to stop email spoofing. Several frameworks are designed to authenticate email messages.
  • SPF (Sender Policy Framework): It recognizes whether a certain IP is valid to send emails from a given domain or not by checking the SPF record.
  • DKIM (Domain Key Identified Mail): In this method, cryptographic keys help to validate the incoming messages and sign the outgoing messages.
  • DMARC (Domain-Based Message Authentication, Reporting, and Conformance): It gives an option to know whether the sender’s email is protected by SPF or DKIM. It also gives an idea about in case of authentication failure what actions needs to be performed with the  email.
