Even eCommerce firms struggle to put in place effective email spoofing prevention because of the world’s overwhelming cybercrime problem. Hackers are impersonating Amazon employees to send bogus emails and texts. The state with the most reported losses from cybercrime in the United States in 2021 reported losses from domain spoofing emails totaling over 1.2 billion dollars. Texas, which came in second, reported losses of over 606 million dollars.
To spread viruses onto devices, hackers trick their intended victims into providing sensitive information. This kind of information highlights how crucial it is to comprehend email spoofing. Learn how to protect against email spoofing by SPF or the Sender Policy Framework.
What Is SPF?
SPF is an email authentication method to stop phishing and spoofing attacks. It uses email as its medium. Only trusted IP addresses may send emails using your domain name.
Because malicious links are not authenticated and cannot get to a recipient’s mailbox, malicious links can’t damage your company’s reputation. It’s useful to understand how an SPF record functions, and how to protect against email spoofing with SPF.
Following are instructions on how to use SPF to protect against domain email spoofing and phishing.
Email Spoofing: What is It?
By setting up an SPF record, you get the answer to how to protect against email spoofing with the SPF lookup tool.
What, however, is email spoofing?
Well, it’s cybercrime when spam emails are sent while posing as a reliable business or person. To deceive users into revealing important information, send phony emails that seem real.
Common Reasons for Email Spoofing Attacks
Cybercriminals use email spoofing to achieve a variety of hidden objectives:
- Changing their names
- Getting around a spam blocklist
- Damaging a brand’s reputation
- Wishing to harm another individual
- Requesting money transfers
- tricking victims into providing sensitive information, such as passwords and login information
- Getting targets’ financial information or OTPs through fraud
How Are Spoofing And Phishing Related?
Knowing how phishing and spoofing are related is helpful before discussing how to prevent email spoofing with SPF.
Hackers use the social engineering technique of phishing to trick you into disclosing private and sensitive information. They then carry out illegal acts using information like social security and login credentials.
Phishing attacks are effective because they use emails made to appear authentic and to come from a reliable source. These hacks use characteristics of urgency, terror, or excitement to prey on human nature.
A phishing email impersonating an urgent bank message, for instance, can request your login information because your account is hijacked. It can appear to be a message from your boss asking for private information that requires you to click on a dangerous link.
By verifying that an email is being sent from a reliable and reputable domain, you can prevent phishing assaults. Red flags also include things like misspellings, unrequested or unknown links, files, strange requests, etc. Spoofing is passing off illegal communication as genuine. From domain names and websites to phone numbers and email addresses use them all.
They typically send emails using a typosquatting or expanded email domain while email spoofing. Cybercrime called typosquatting involves criminals registering domains with deliberately misspelled names to entice victims to click on dangerous links.
Since they work together to create an email from a reliable source, spoofing and phishing are interchangeable. Hackers disguise their phishing attempts and deceive receivers by using email spoofing protection techniques.
Protective Measures Against Spoofing
By ensuring that emails sent from approved IP addresses are delivered, SPF safeguards protect against email spoofing. All trusted IPs from which emails are sent to recipients’ mailboxes are listed using TXT entries in the DNS. When you generate an SPF record to DNS, businesses can stop phishing and spoofing attempts.
The destination email server verifies an email before delivery by comparing the IP address to the IPs listed in the DNS records.
All allowed IP addresses and domain names of sending mail servers are listed in SPF TXT records. Knowing the three components of SPF records might help with understanding SPF creation:
These are the techniques SPF service can use to verify if a specific domain may send emails or not. Upon meeting certain criteria, the mail can be validated, and mechanisms can match (depending on the mechanism in question).
Qualifiers: + (pass), – (hard fail), ~ (soft fail), ? (neutral)
The aforementioned mechanisms can have these optional prefixes for them to describe what happens when a match occurs.
Changes: Redirect and Exp
These optional additions offer more details without altering the way messages are authenticated. Usually, in order to create SPF records, all three elements are required.
What Should You Do?
To use SPF to safeguard against email spoofing, follow these simple steps. Below, you’ll find pertinent guidelines and resources.
Prior to installing SPF
- Get the login information for your domain provider.
- Know what your IP addresses are.
- Discover DNS TXT records.
- See if your domain already has an SPF record.
- Make a list of all the IP addresses you want to let use your domain to send emails.
SPF is an important email authentication technique that can stop email spoofing, but it has the following drawbacks:
- Since forwarded emails lack the IP addresses of the original senders, they don’t function well with them.
- To include all legitimate IP addresses permitted to send emails using your domain name, senders frequently neglect to keep their SPF records updated. It has approved third parties.
- You can use the Mail From domain for SPF verification, which is largely hidden from the recipients.
Fortunately, there is a way around this restriction. You can use DMARC (short for Domain-based Message Authentication, Reporting, and Conformance) and DKIM (short for DomainKeys Identified Mail). It is best to implement SPF, DKIM, and DMARC to prevent domain spoofing email techniques.
By using an authentication method based on cryptography, DKIM enhances SPF. It verifies the email’s authenticity and checks if hackers have tampered with or altered it while it was in transit.
The Bottom Line
DMARC creates an additional layer of protection using DKIM and SPF protocol to defend against email spoofing and other intrusions.
DMARC helps keep recipients safe from these attacks by preventing phishing and spoofing and protecting your domain from cyber attackers. Upgraded security standards are implemented by GoDMARC, an email expert, to safeguard brand reputation.
One of the email security systems that clients love the most is their SPF Record Checker. With GoDMARC SPF, more than a thousand businesses create a secure emailing solution. They construct crucial email networking by using a single-text TXT record specification rather than a conventional TXT record type.
Q1. How to avoid email spoofing?
Email authentication should be put up by Gmail administrators to safeguard corporate email. Authentication aids in avoiding spam labels being applied to communications from your company.
Q2. What is spoofing protection?
Unknown devices are prevented from entering by this security precaution. A hacker can trick an otherwise secure network by changing the IP address of their device via an IP spoofing attack. In order to prevent hackers from impersonating you, you can mask your IP address.
