Modelagem de ameaças leve para web apps, sites e apps com LLM — inventário de ativos, fronteiras de confiança, fluxos de dado, STRIDE por fronteira e saída em requisitos de segurança testáveis que viram critério de aceite de story. Use antes de feature nova com auth, pagamento, dado pessoal, upload, integração ou IA.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Modelagem de ameaças
O objetivo não é um documento bonito: é uma lista curta de **requisitos testáveis** que entram como critério de aceite nas stories antes de o código existir. Modelo que não vira requisito não protegeu nada.
## Quando modelar
Feature nova ou mudança em: login/cadastro/sessão · papéis e permissões · pagamento · dado pessoal (lead, cliente, documento) · upload de arquivo · webhook ou integração de terceiro · chamada a modelo de IA com tools ou com dado do usuário · painel administrativo · API pública.
Mudança de texto, estilo ou página estática sem formulário: não precisa.
## Passo 1 — Ativos (o que vale proteger)
| Ativo | Onde mora | Quem deveria acessar |
|---|---|---|
| ex.: leads (nome, e-mail, WhatsApp) | tabela `leads` | só o painel interno |
## Passo 2 — Fronteiras de confiança
Desenhe o caminho do dado e marque cada ponto onde ele **muda de dono de confiança**:
```
navegador (não confiável) → rota de API / server action → banco (RLS) → storage
→ provedor de IA (prompt) → tools (ações reais)
→ webhook de terceiro (não confiável) → rota de servidor
```

How to install
mdr add joaoguirunas/team-os/security-threat-modeling@sha256:cbcca54ba05e4da7The line at the top of this page pins the label v1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
