Techniques Attackers Use To Evade Email Security

The article discusses the evolving landscape of email-borne threats and the techniques attackers use to bypass traditional email security measures. It highlights several evasion tactics, including obfuscation of email attachments and content, executive and vendor impersonation attacks, polymorphic payloads, compromised legitimate accounts, and domain spoofing. These methods allow attackers to disguise malicious elements, impersonate trusted individuals, dynamically change attack signatures, and exploit legitimate accounts, making detection challenging for conventional security systems.

To combat these threats, the article suggests several strategies for organizations. It emphasizes the importance of boosting security intuition through employee training and phishing simulations, adopting a zero-trust security architecture to limit adversary movement, and leveraging AI-based email security tools that utilize machine learning and natural language processing. By implementing these measures, organizations can better protect themselves against sophisticated and evasive email threats.

Key takeaways:

Email threats are evolving with techniques like obfuscation, impersonation, and polymorphic payloads to bypass traditional security measures.
Compromised legitimate accounts are a significant source of email security breaches, with many users reusing passwords across sites.
Domain spoofing and the use of new gTLDs are common methods for evading detection by email security tools.
Organizations can mitigate these threats by boosting employee security awareness, adopting zero-trust security, and leveraging AI-based email security tools.
