AI is both weapon and target: Noam Schwartz on the new threat landscape

Almost every incident worth writing about starts with something that was working exactly as designed.

Paycux engineering

Almost every incident worth writing about starts with something that was working exactly as designed. The design was just describing a different world than the one the system ended up in.

This piece walks through how we think about it at Paycux, what we have changed our minds about, and where the sharp edges are.

From content moderation to AI safety

Consider from content moderation to ai safety. Blast radius is the metric that actually matters. A credential that can read one organization's data is an incident; the same credential scoped to every organization is a company-ending event, and the difference is a design decision made months earlier.

Rotate on a schedule, not on an incident. A rotation path that has been exercised is a routine change; one that has never been used is an outage waiting for the worst possible moment.

AI As both weapon and target

AI As both weapon and target deserves its own treatment. Blast radius is the metric that actually matters. A credential that can read one organization's data is an incident; the same credential scoped to every organization is a company-ending event, and the difference is a design decision made months earlier.

Detection beats prevention when prevention is uncertain. If you cannot stop a class of abuse outright, make sure it produces a signal loud enough that someone sees it the same day.

  • Scope credentials to the smallest useful blast radius
  • Alert on the abuse you cannot prevent
  • Exercise the rotation path before you need it
  • Log the decision, not just the outcome

The democratization of attacks

What's coming: multi-model architectures and a production reckoning

The new threat model

The new threat model is where this gets concrete. Blast radius is the metric that actually matters. A credential that can read one organization's data is an incident; the same credential scoped to every organization is a company-ending event, and the difference is a design decision made months earlier.

Where this leaves us

None of this is exotic. It is the ordinary discipline of deciding what you own, writing down what you assume, and making the failures loud enough to notice.

If you are working through the same problem and want to compare notes, the docs cover the mechanics and the console shows the behaviour on your own data.
