CAIN-42 CAIN StudioAttack lab
Type any text: the demo signs a disclosure for it, verifies the original, then verifies an edited copy.
2 attacks 2 controls live: nothing pre-recorded
- Pick a preset. Red ones are attacks, green ones are honest requests that must still work.
- Tamper. Choose any field and drop it, null it, change its type, upper-case it, flip one character, or add a field the product never asked for.
- Send and read the real reply, or run every preset and watch the scoreboard fill.
What each preset tests
| Preset | Route | Why it matters | |
|---|---|---|---|
| control | Original product description verifies | POST /catalog-demo/content-provenance/run | Same content as signed: valid. |
| attack | Edited copy of the same description fails | POST /catalog-demo/content-provenance/run | One change and the fingerprint no longer matches. |
| control | A quarterly summary: original verifies | POST /catalog-demo/content-provenance/run | Valid. |
| attack | The same summary after editing fails | POST /catalog-demo/content-provenance/run | Fails: the label cannot follow edited content. |
Each button signs and checks on the live service. Shared demo; rate limited per address.
