What happened
Scammers posted social media ads that used a purported AI-generated likeness of Commissioner Peter Mersi to invite people to a closed webinar about upcoming crypto tax changes. Inland Revenue New Zealand issued a public warning about the impersonation and RNZ reported the scam, characterising the material as a social-media impersonation using synthetic media. The posts promoted a fake webinar intended to deceive recipients into engaging with the scam.
What broke inside the model
- 01 · TriggerThe agent selects the correct tool.
- 02 · Model stepIt fills the call with the wrong arguments.
- 03 · Control gapNo validation checks the arguments first.
- 04 · FailureThe tool runs against the wrong target.
- 05 · ConsequenceThe wrong record, account, or system is hit.
At the tool call, the arguments point at the wrong target.
Operators misused generative synthetic-media tools to create a convincing likeness of a public official and used paid or promoted social ads to distribute the content. Platform-level moderation and ad verification mechanisms failed to block or remove the impersonating ads quickly enough for Inland Revenue to prevent the scam postings from reaching users. The incident reflects misuse of synthetic-media generation combined with gaps in ad-safety and impersonation detection.

Realm can inspect a tool call against the user's actual intent before it runs, and hold calls whose arguments or target do not match what was asked, so the wrong tool or the wrong arguments never reach the system of record.
