Email spoofing, a problem since the 1970s, gained traction in the 1990s and became a global cybersecurity issue in the 2000s. Security protocols introduced in 2014 divert many spoofed emails to spam boxes or reject them altogether.

Email spoofing tricks users into thinking a message is from a trusted source, leading them to click on malicious links or open harmful attachments. The technique exploits the design of email systems, where client applications assign sender addresses, making it challenging to distinguish between legitimate and forged ones.

While recipient servers and antimalware software help filter out spoofed messages, not all email services have robust security measures. Users can enhance their safety by scrutinizing email headers and verifying sender legitimacy through trusted channels. Understanding history and taking simple precautions empower individuals to navigate the digital landscape securely.

How Email Spoofing Differs from Phishing

What are the Reasons for Email Spoofing?

Email spoofing is typically driven by malicious intentions, with criminals aiming to exploit vulnerabilities for various purposes. 

Here are the primary motivations behind this illicit activity:

Phishing Attacks 

Email spoofing serves as a common strategy for phishing attempts. By impersonating someone familiar to the recipient, criminals seek to deceive individuals into clicking on malicious links or divulging sensitive information.

Identity Theft 

Impersonating another person enables criminals to gather extensive data on their victims. This tactic may involve requesting confidential information from financial or medical institutions, contributing to identity theft and potential further exploitation.

Evading Spam Filters 

Perpetrators of email spoofing often engage in frequent switching between email addresses. This practice helps spammers circumvent detection mechanisms and avoid being blocked by spam filters, allowing them to continue their malicious activities unhindered.

Maintaining Anonymity 

Using fake email addresses provides a cloak of anonymity for senders, allowing them to conceal their true identity. This anonymity facilitates the execution of various cyber crimes without immediate attribution, making it challenging for authorities to trace and apprehend the culprits.

How Does Email Spoofing Work?

Email spoofing is a trick fraudsters use to make you think an email is from someone you trust, like a coworker, a company, or a friend. They want to use that trust to get you to share sensitive information or do something you shouldn’t.

When you send an email, your email program usually fills in the sender’s address. However, hackers can use scripts in different computer languages to make it look like an email is coming from any address they choose. Email systems have ways for senders to specify their address, even if it’s fake, and the servers that send emails can’t always tell if the sender’s address is real.

Emails travel through the internet using Simple Mail Transfer Protocol (SMTP). When you click “Send,” your email goes to your email provider’s server, figuring out where to send it next. Each step of this journey is recorded, including the IP addresses of the servers. These details are in the email’s headers, but most people don’t check them.

An email has three main parts: who it’s from, who it’s going to, and the message itself. But in phishing attacks, there’s another part called the Reply-To field. The sender can set this to make replies go elsewhere, even if it’s not their real address. The email servers and protocols don’t always check if this is legit, so it’s up to you to notice if the reply is going to the wrong place.

How Can I Identify a Spoofed Email?

As scams become more sophisticated, it’s important to be vigilant and recognize signs of a spoofed email. Here are some practical tips to help you identify them:

Examine the email header 

Look at the email header, which includes details like the date, subject line, sender’s and recipient’s names, and email address. Ensure that the email address is legitimate and matches the other details provided.

Check for inconsistencies in addresses and names 

Be wary if the email address doesn’t match the sender’s display name, especially if the email address’s domain seems suspicious. Genuine emails usually have consistent information.

Evaluate the email content 

Spoofed emails often use alarming language to create a sense of urgency. If the subject line and content seem designed to scare or pressure you, it’s likely a spoofed email.

Beware of requests for personal information 

Spoofed emails are often part of phishing scams, where scammers impersonate trusted entities to obtain your personal information. Be cautious if an email requests sensitive data.

Avoid clicking on links or downloading attachments 

If you receive an email from an unfamiliar sender that seems suspicious, refrain from clicking links or downloading attachments. These could be harmful and compromise your security.

Use a search engine for email content 

Copy and paste the email content into a search engine. If it’s a common phishing attack, chances are that others have reported it online. This can help you confirm the legitimacy of the email.

Look for inconsistencies in the email signature 

Examine the information in the email signature, such as the telephone number. It may be a sign of a spoofed email if it doesn’t align with what you know about the sender.

How to Safeguard Yourself from Email Spoofing?

Protecting your email from spammers is crucial, and there are simple ways for both individuals and businesses to do so:

Use an Email Security Gateway 

Deploying an email security gateway helps stop suspicious emails from entering or leaving your system. It’s like a security guard for your emails, blocking harmful content and potential phishing attacks.

Install Antimalware Software 

Install software that identifies and blocks harmful websites and fraudulent emails before they reach your inbox. This adds an extra layer of protection against malicious activities.

Encrypt Your Emails 

Keep your emails safe by using encryption. It is a secret code only the intended recipient can understand. This prevents unauthorized access and ensures the sender’s legitimacy.

Follow Email Security Protocols 

Employ security protocols like DomainKeys Identified Mail (DKIM) to add a digital signature, ensuring the email’s authenticity. Domain-based Message Authentication, Reporting, and Conformance (DMARC) helps define actions against suspicious messages.

Verify Senders with Reverse IP Lookups 

Confirm the real sender by checking the associated domain name and IP address. Also, consider publishing a DNS record to specify who can send emails on your behalf.

Train Employees on Cyber Awareness 

Educate your team about cybersecurity. Regular training can help them recognize and handle potential threats. Stay updated on new risks and teach employees how to respond when they encounter suspicious emails.

Be Cautious of Unknown Email Addresses 

Pay attention to the email addresses you interact with. Be cautious if an email seems unusual or is from an unknown source. Attackers often use the same tricks repeatedly, so staying alert is crucial.

Avoid Sharing Personal Information 

Never share personal information through email, even if the message seems legitimate. This practice minimizes the impact of email spoofing, as attackers rely on users divulging sensitive details.

Steer Clear of Suspicious Attachments and Links 

Don’t open attachments or click on links from unfamiliar sources. Scrutinize emails for signs of phishing, such as misspellings or strange file extensions, before taking action. It’s a good practice to be cautious.

Imagine this scenario: a sneaky attacker creates an email that appears to be from PayPal. The email claims that the user’s account is at risk of suspension unless they urgently click on a provided link, log in to the website, and update their account password. This is a classic case of email spoofing, where the bad actor tricks the recipient into taking actions that could compromise their personal information and security.

Spoofing is a criminal act embraced by cybercriminals. This type of cybercrime occurs when someone falsely represents themselves by making it seem like an innocent person’s email address is the one sending an email.

A hacker can make it seem like they’re sending emails from your account without actually taking it over. When your email is hacked, it means the attacker has full control over it, and the emails they send genuinely come from your account. In contrast, email spoofing doesn’t involve taking control of your account. Your account stays safe, but the email looks like it’s from you when, in reality, it’s sent from a completely different account.
