Protect Your Business Email

One of the most common threats associated with domain impersonation is email phishing.

Attackers may use a lookalike domain to send fraudulent emails pretending to be from your company. Taking proactive steps to secure your email communication can prevent these attacks.

Set Up SPF, DKIM, and DMARC Records

• SPF (Sender Policy Framework) helps email servers verify that emails claiming to be from your domain are sent from authorized servers.
• DKIM (DomainKeys Identified Mail) adds a digital signature to outgoing emails to confirm their authenticity.
• DMARC (Domain-based Message Authentication, Reporting, and Conformance) tells email servers how to handle messages that fail SPF or DKIM checks.
• Implement these records through your domain provider’s DNS settings.

Monitor for Phishing Attacks

• Regularly check services like MXToolBox (https://mxtoolbox.com/) to monitor your domain’s email reputation.
• Set up DMARC reporting to receive alerts about unauthorized email activity.
• Train employees to recognize phishing emails, including unexpected requests for credentials or sensitive data.

Warn Your Customers and Employees

• Publish an official statement on your website and social media warning about potential phishing attempts.
• Encourage customers to verify email senders and avoid clicking on suspicious links.
• Use email disclaimers or banners to highlight messages sent from outside your organization.

Report Phishing Domains

• If phishing emails are sent from an impersonated domain, report the domain to its registrar and hosting provider.
• Submit the phishing emails to Google Safe Browsing (https://safebrowsing.google.com/) and Microsoft’s phishing reporting tool (https://www.microsoft.com/en-us/wdsi/support/report-unsafe-site).
• Encourage users to mark phishing emails as spam to help improve filtering by email providers.

Taking these steps can significantly reduce the risk of phishing attacks and protect your business reputation.
