Quotes:
"Phishing targets the human element, the 'wetware,' often the weakest link in any security chain." - Clint Marsden
"Phishing isn't just about poorly spelled emails anymore; it's about sophisticated campaigns that even cyber-aware individuals can fall victim to." - Clint Marsden
"Effective defense against phishing involves not just technology but ongoing education and a culture of security awareness." - Clint Marsden
Key Takeaways:

Phishing attacks continue to evolve and remain a significant cybersecurity threat despite advances in technology.
Attackers leverage sophisticated techniques including AI and social engineering to exploit human psychology.
Effective defense strategies involve a multi-layered approach including user education, advanced email gateway technologies, and stringent access controls.

Action Points:

Implement ongoing and evolving user education programs to enhance awareness of phishing tactics.
Ensure email gateways are configured with DKIM, SPF, and DMARC protocols, and ensure the SEG is tuned appropriately to filter out malicious emails
Follow the Essential 8 guidelines, focusing on restricting Microsoft Office macros and restricting admin privileges. If you've got the capacity, go straight into application control.
Implement multi-factor authentication (MFA) across all public-facing and internal systems to add an additional layer of security against phishing attempts.
