Xiaomi replayed its own users' MiMo conversations and coding sessions through Claude via 1,500+ proxy accounts, and had Claude rebuild developer environments, rewrite and generate conversations, and grade answers as training data.

| × Contribution | 2 | Ran the operation: Anthropic says Claude "was used to reconstruct the developer environments from exchange transcripts", converted multi-turn conversations into cleaner exchanges, generated both sides of synthetic developer conversations, and judged answer quality, so Claude did the data-processing work of the campaign. |
| × Blast Radius | 0.5 | Own lab's production: The victim is Anthropic, the lab whose own model did the work, so blast radius is own lab's production. |
| × Legal status | 0.5 | Legality contested. |
| + Tradecraft | 0 | The proxy-account routing was Xiaomi's, and the report credits Claude with no intrusion techniques, so tradecraft is empty. |
| + Guardrails | 0 | Guardrails intact: The report describes routing through proxy services, not any defeat of Claude's safety training; the tasks were ordinary coding and data work, so guardrails are scored intact. |
| + Dwell Time | 0 | The report dates the traffic to "20 days in March and April 2026", so date_precision is month with 2026-03-01; dwell is counted conservatively as 0 days and never inflated, and Anthropic detected it itself. |
