  "Smart contract security is changing at a pace that is shocking..." [15:14]
  Constantly evolving tactics targeting blockchain protocols, private key management, and more.

• Stockholm vs. Bearish on Attack Complexity:
  While traditional attacks remain prevalent, the rise of sophisticated, targeted assaults reflects the high-stakes environment of cryptocurrency exchanges.

6. User Education and Scams

Philip emphasizes the importance of educating users to combat scams:

• Trading Scams Defined:
  "There are no new scams, just new iterations with different presentations." [19:08]
  Focuses on confidence scams that trick users into transferring funds to malicious actors.

• Educational Initiatives:
  "Educated folks are much less likely to fall victim to scams." [19:08]

7. Authentication Mechanisms and Best Practices

Exploring robust authentication strategies:

• SingPass Integration:
  "We see [SingPass] as making things a little bit easier for our customers." [26:03]
  Enhances user experience by integrating government digital identity systems while maintaining stringent security measures.

• Two-Factor Authentication (2FA):
  Advocates for hardware-based 2FA methods like Yubikeys over software solutions for superior security reliability.

• Passkeys vs. Yubikeys:
  Highlights the security vulnerabilities in software-backed passkeys and expresses a preference for hardware-based solutions for stronger assurance.

8. Future Concerns: AI and Quantum Computing

Addressing emerging technologies and their security implications:

• AI in Phishing:
  "We expect an uptick in phishing sophistication, particularly with the use of chatbots." [32:11]
  Discusses how AI can enhance the volume and consistency of phishing attacks, making them more pervasive.
