Understanding Display Name Spoofing and Email Filtering Services

Display Name Spoofing

To pass for a trustworthy organization, an attacker may use a dishonest technique called “display name spoofing” in phishing emails. The intention is to increase the probability that the recipient will open the email and interact with its content — by deceiving them into thinking it is from a reliable source. An email with the display name “Your Bank,” for instance, could be sent by an attacker even if it is not from your bank. This strategy can work well, since a lot of email clients only display the display name by default. Display name spoofing poses a serious risk due to its ease of use and potential for great effectiveness. It takes advantage of people’s faith in the display names.

Email Filtering Services

Keeping users safe from phishing and spam is one of the main purposes of email filtering services, which offer tools for managing and organizing incoming emails. They operate by analyzing incoming mail through predefined rules or algorithms, then making decisions based on those rules. A few possible actions are to move the email to a designated folder, mark it as read, or even delete it. They accomplish this by looking through incoming emails to find common traits in unsolicited emails.

This is how to do it:

  1. Spam Filters: A common feature of email filtering services is the inclusion of spam filters, which scan incoming emails for common spam traits like spoof display names.
  2. Phishing Protection: With built-in phishing protection, many email filters are capable of identifying common phishing techniques, like display name spoofing.
  3. Blacklists and Whitelists: Users are able to make lists of known malicious senders on their blacklists, and trusted senders on their whitelists. You can choose to automatically mark or delete emails from senders on your blacklist.
  4. User Reporting: A few email filters let users report emails that they think might be phishing scams. This facilitates the filter’s ongoing learning and development.

Domain-based Message Authentication, Reporting & Conformance (DMARC): This email authentication protocol allows domain owners to designate what happens to emails from their domain that don’t pass authentication checks. It offers receiving mail servers a mechanism to verify that incoming mail from a domain originates from a host approved by that domain’s administrators, which can aid in preventing display name spoofing.

How can companies train their users to spot display name spoofing?

As part of an organization’s cybersecurity plan, users need to be trained to identify display name spoofing. The following are some tactics that businesses can implement:

  1. Awareness Training: Educate staff members about the dangers of display name spoofing and other phishing techniques through frequent training sessions. Illustrate these attacks with examples from everyday life.
  2. Phishing attack simulations: Provide simulated phishing attacks to staff members, so they can gain hands-on experience spotting spoof emails. Testing the efficacy of your training and determining which areas require additional training can be accomplished in this way, too.
  3. Email Policies: Put in place and uphold email policies that dissuade recipients from opening unexpected attachments or clicking on dubious links. Make sure that everyone is aware of and understands these policies.
  4. Frequent Communication: Keep everyone informed about the most recent phishing attacks, such as display name spoofing. This can support education and vigilance among staff members.
  5. Promote Reporting: Tell staff members about any suspected phishing attempts. This can speed up your IT staff’s ability to recognize and address threats.
  6. Verify the Email Address: Before replying to an email, instruct users to confirm the email address, and not just the display name.
  7. Look for Phishing Signs: Inform users to watch out for typical indicators of phishing, such as misspelled or poorly capitalized words, requests for personal information, and cliched greetings.

In Cyber Security, people are frequently the weakest link. Organizations can diminish their risk considerably by teaching users about display name spoofing and other dangers.

What are some warning signs of potential email spoofing? 

  1. Dissimilar Email Addresses: Although the display name seems correct, the corresponding email address might come from a different domain. Always check the entire email address, rather than just the display name.  
  2. Unexpected Emails: Avoid opening unexpected emails, particularly if they ask for quick action or include dubious attachments or links. 
  3. Generic Salutations: Phishing emails frequently employ salutations like “Dear Customer” in place of your real name. 
  4. Incorrect Grammar and Spelling: Professional firms typically employ teams to make sure their emails are free of errors. Spelling and grammar errors may indicate a phishing email, although bad actors are leveraging AI to improve their spelling and grammar. 
  5. Requests for Personal Information: Trustworthy companies generally avoid requesting private information through email. Any email asking for financial or personal information should raise suspicions. 
  6. Strange Sender Behavior: If you receive an email from someone you know, but something about the language, tone, or mannerisms seems strange, it might be a spoof email. 
  7. Seems Too Good To Be True: An email offer is most likely fraudulent if it looks too good to be true. Emails that offer surprising gifts or discounts should be avoided. 
  8. Threats or Urgency: Phishing emails frequently incite fear or a sense of urgency to demand a quick response. Emails urging you to take immediate action should be avoided. 

What actions should I take if I think an email is spoofing? 

  1. Avoid clicking on any links or downloading any attachments as they may be malicious and cause damage to your computer or steal personal data. 
  2. Don’t Answer or Give Any Information: Answering an email can let the sender know that you are still active. Additionally, you should never reply to an unsolicited email with financial or personal information.  
  3. Report the Email: Most email programs allow users to flag emails as phishing or spam. This enhances the spam filters that are provided by your email provider.  
  4. Speak with the Presumptive Sender: To find out if the email is authentic, send a follow-up email to a verified address (do not just click “Reply”); or call them on a verified number if it seems to be from a known person or business. 
  5. Delete the Email: Remove the email from your inbox as soon as you’ve reported it to avoid inadvertently opening it again. 
  6. Update Your Passwords: Change your passwords if you think someone has accessed your email account. To come up with strong, one-of-a-kind passwords, think about utilizing a password organizer.  
  7. Turn on two-factor authentication. This gives your accounts an additional layer of protection and makes it more difficult for hackers to access them. 

How do I strengthen the security of my emails overall? 

Enhancing email security is a multifaceted strategy that includes user education along with technical solutions. The following are some methods to improve your email security in general: 

  1. Make Sure Your Passwords Are Strong: Give your email accounts complex, one-of-a-kind passwords. Create and save secure passwords with a password manager. 
  2. Turn on Two-Factor Authentication (2FA): 2FA adds an extra layer of security by requiring a second form of verification, in addition to your password. 
  3. Be Alert for Unsolicited Emails: Be careful when responding to unsolicited emails, especially if they ask for personal information or demand that you take urgent action. 
  4. Avoid Clicking on Dubious Links: Take caution when clicking on links in emails that you weren’t expecting or that seem fishy. To view the real URL instead, move your mouse cursor over the link. 
  5. Make Use of Email Filtering Services: These services can assist in identifying and removing phishing and spam emails. 
  6. Consistently Update Your Email Client Software: Make sure your email client software is updated on a regular basis. Security patches for known vulnerabilities are frequently included in updates. 
  7. Encrypt Sensitive Emails: To prevent data from being intercepted, encrypt emails containing sensitive information. 
  8. Educate Yourself and Your Team: Continually inform yourself and your group about the most recent email scams and how to spot them. 
  9. Make Regular Email Backups: Regular backups will enable you to retrieve your email should you become the target of a ransomware attack, s. 
  10. Report Suspicious Emails: Contact your email provider to report any suspicious emails you receive. By doing so, they can safeguard other users and enhance their spam filters. 

Conclusion 

Email filtering services are a useful tool for mitigating the threat of display name spoofing, but significant security challenges still exist. Users can enhance their security and safeguard their data in the digital realm by comprehending these risks and the countermeasures at their disposal.
