Saw this on the other site but I should comment here:
Can't remember his hacker handle but I think Pad & Gandalf of 8lgm were arrested the same day in 1991.
You may not know it but the entire infosec & software industries owe 8lgm immense gratitude for making vendors accountable for their vulns

Exactly this. We should instead be investing that energy into making authentication in our environment unphishable by making it impossible to give away access to an attacker, even if someone actually wanted to.
I have never once run a phishing sim. I refuse to use the word. I put it in air quotes and say scam by text or email etc
Tech and cyber has been about deflecting blame to anyone else but themselves- which is what sims are. Blaming people when the system they use should protect against issues.

I'm really liking the crisp definitions of and boundaries between product engineering, domain engineering, and infra engineering in this.
How much of your security org builds "what any company would need" (infra) vs. "what is unique to this company but shared across the company" (domain) ?

There are different privacy concerns and approaches for the training phase of AI as well as for the inference phase of using it. It's a good time to be thinking about what the right approaches are for each.

Fraud is such a broad thing, hard to answer. But I think better forms of digital and cryptographic proofs of selective identity information would help. For example, cryptographic proof of personhood, while still remaining anonymous would help reduce amount of bots and such on social media.

That is true that it is not cool, but the shift to EMV also happened in the US with cardholders not being liable for fraudulent charges by law. I'm not sure what the laws were in AU, but wonder if that was only the situation in EU/UK?

The way that I think about it is that the systems that I think about the security of have grown larger and more complex. Being Security DRI for Square's EMV launch in 2014 was really educational. True to my roots, I found EMV smartcard parsing mem corruption bugs in our firmware before it shipped :)
