- Use an AI-powered Email Security Solution
Traditional email security measures, like spam filters, struggle against modern phishing attacks. Criminals develop new strategies faster than filters can update. The solution: fight AI with AI. AI-powered email security uses machine learning to detect and block threats. It discerns email sources, blocks suspicious ones, and reduces false positives. It verifies senders, scans for malicious attachments, and checks links for vulnerabilities.
- Do Not Open Unknown or Unexpected Attachments
Cybercriminals disguise harmful files as harmless documents. Do not open attachments from unknown senders. Be cautious with unexpected attachments from known senders; they could be spoofed or compromised. Verify the sender through another communication method before opening. Watch for misspellings or unusual domains. Avoid executable files (.exe, .bat) and be cautious with archive files (.zip, .rar). Regular cybersecurity training is essential, including simulated phishing attacks to identify and train vulnerable staff.
- Utilise a URL Protection Solution
Malicious links within emails are a common tactic to direct victims to phishing websites. In fact, 38% of phishing emails use a URL to deliver their payload, such as malware or ransomware. These links are often disguised as seemingly legitimate links, and even the most tech-savvy employees can be fooled.
- Implement DMARC and DKIM
DKIM (DomainKeys Identified Mail) adds a digital signature to outgoing emails, verified by receiving mail servers, ensuring the email's integrity. As a domain owner, you publish an SPF record in your DNS settings, listing authorized mail servers.
DMARC (Domain-based Message Authentication, Reporting, and Conformance) provides a policy for handling emails that fail SPF and DKIM checks, such as monitoring, flagging, or quarantining them. Setting up DMARC, DKIM, and SPF can be complex, so working with a trusted cybersecurity partner is recommended.
- Verify Unexpected Requests Using Another Form of Communication
Even with strong safeguards, some email attacks slip through. Always verify unexpected requests using another communication method. For suspicious requests, like accessing sensitive info or fund transfers, contact the sender directly via phone or another trusted channel. Be wary of urgent requests, as attackers create urgency to pressure victims. Report suspicious emails to your security team promptly.
