Protect your customers against spoofing with anti-spoofing software

Social engineering attacks continue to threaten today’s top businesses, and attacks utilizing email spoofing tactics are on the rise. Email spoofing is the act of forging a sender display name or the “From” email field to trick the recipient into believing the email comes from a trusted source. When a user opens the malicious email or clicks on a fraudulent link, the hacker can steal sensitive information. To protect customers from a range of today’s social engineering threats, it’s essential for MSPs to implement a layered security approach.

N-able™ Mail Assure is a powerful cloud-based email security solution that should form part of your core security layer. N-able Mail Assure scans emails, analyzes the IP and domain reputation of the sender, and performs multiple content, header, and sender checks for malicious content. The tool also blocks email threats with 99.999% accuracy, so your customers get email protection they can trust.

Authenticate the senders of incoming emails using key email security policies

When it comes to email protection, most security frameworks are built to help establish the identity of the sender—since scammers often trick users via impersonation. Whether it’s forging a sender address or masquerading as a legitimate third-party organization like a bank, bad actors often pose as someone else as part of their attacks. To prevent this, N-able Mail Assure supports multiple security policies that help authenticate email senders and stop email spoofing.

For example, the DomainKeys Identified Mail (DKIM) protocol uses cryptography to verify an email was sent from the domain it claims to be from. Sender Policy Framework (SPF) also helps ensure an email comes from a legitimate source. To take email spoofing policies to the next level, Domain-based Message Authentication, Reporting, and Conformance (DMARC) expands upon DKIM and SPF to work in parallel against impersonation threats. Put together, these features help ensure that only safe and authenticated emails make it to your customers’ inboxes.

Fight back against a wide variety of cyberattacks with comprehensive email protection

Email spoofing software is only one part of a comprehensive email protection plan. While the use of DKIM, SPF, and DMARC help dramatically reduce email fraud by establishing the authenticity of the sending domain, MSPs must also protect their customers against other kinds of social engineering attacks like spear phishing and phishing, malware, ransomware, and more. Most anti-spam technologies were historically set up around rule-based filtering and unblocked/blocked lists, which won’t help in the event of domain misspellings or bad actors posing as trusted friends with a new email address.

To keep up with the latest threats, N-able Mail Assure uses machine learning and collective intelligence data gathered from over 23 million inboxes to protect your customers against a wide variety of email-based threats—not just email spoofing. Attachment and macro blocking help protect against zero-day malware, email filtering actively blocks threats, and users are given full authority to manage their own blocked and unblocked lists. Coupled with user training and awareness, you can rest assured that your customers will be well protected.

Monitor emerging threats and the latest email spoofing techniques

Providing comprehensive email security can be challenging because cybercriminals frequently change their tactics—and new viruses and threats are constantly emerging.

N-able Mail Assure uses artificial intelligence and machine learning to help prevent email attacks, whether they’re attacks that MSPs encounter often or morphing viruses that have not previously been discovered. This tool is equipped with technology designed to help catch rapidly changing attacks, even if your organization has never encountered them before.

The proprietary email filtering technology used in N-able Mail Assure processes large volumes of email data and combines it with real-time pattern threat recognition and collective threat intelligence to help protect your users against emerging email-borne threats. With this solution, your email spoofing software and malware protection protocols will be kept up to date.

Frequently Asked Questions

What is email spoofing?

What is email spoofing?

Email spoofing is a kind of cyberattack where a hacker forges an email header so that it looks as if the email originated from someone or somewhere other than the actual source. Spoofing is a popular technique used in phishing and spam attacks because people are more likely to mistakenly click on a malicious email if it looks like it originated from a source they recognize and trust.

All a hacker needs to spoof an email is a SMTP server and email software. Once an email has been written, the hacker can easily forge the FROM, REPLY-TO, and RETURN-PATH fields in the message header. When the malicious email reaches its intended target, it will look like it came from a legitimate source.

How can organizations help prevent email spoofing?

How can organizations help prevent email spoofing?

Preventing email spoofing can be tricky because many people don’t look at their emails closely enough to be able to spot a problem. To help prevent email spoofing, you should stay vigilant and employ these best practices:

  • Keep your email spoofing protection and anti-malware software up to date.
  • Limit the amount of private information you share on social media sites, and never share such information through email.
  • Read your email headers carefully and help your team learn to recognize the signs of email spoofing.
  • Use reverse IP lookups to verify the real sender of suspicious emails.
  • Audit email accounts to see how they respond to SPF, DMARC, and similar policies.

At a base level, MSPs should be sure to incorporate anti-email spoofing software into their core security layers.

Why use SPF, DKIM, and DMARC?

Why use SPF, DKIM, and DMARC?

Sender Policy Framework (SPF), DomainKeys Identified Mail (DKIM), and Domain-Based-Message Authentication, Reporting and Conformance (DMARC) are the gold standard of email authentication. These protocols are used to authenticate the sender of an email and prove their trustworthiness, which helps prevent your customers from unknowingly falling for an email spoofing scam.

SPF restricts which mail servers can send emails from a certain domain name, which helps detect and block email spoofing. If you sign an email with DKIM, the recipient will know that the message is from a verified sender and that its contents haven’t been modified by a hacker. When combined with SPF, DKIM helps reduce the likelihood that your email will be marked as spam and discourages hackers from attempting to spoof your emails.

How do SPF, DKIM, and DMARC work?

How do SPF, DKIM, and DMARC work?

SPF works by providing a mechanism that allows mail exchangers to verify that incoming mail from a certain domain comes from an IP that has been authorized by the domain’s administrators. Then, a list of authorized sending hosts and IP addresses are published in an SPF record.

DKIM adds a special signature to your email headers. This signature contains a hashed value of the email’s content—both the body and the main headers. When a server checking for DKIM receives an email with this signature, the DNS of the sending domain will send the server a public key it can use to decrypt the signature and verify the email’s content.

DMARC allows the admin of the recipient to act on messages when criteria aren’t met and gives senders the tools to monitor the abuse of their domains.
