Mapa Final de Ataque - Auditoria RedeDor/Rede D'Or São Luiz

Data: 2026-02-27 Classificação: CRÍTICO - COMPROMISO COMPLETO DA INFRAESTRUTURA Status: AÇÃO IMEDIATA OBRIGATÓRIA


Executive Summary

A auditoria de segurança da Rede D'Or/RedeDor identificou comprometimento crítico e completo da infraestrutura através de um ataque em cadeia iniciado por credenciais expostas em histórico de Git.

Achados Críticos em Números

  • Entry point: @rededor/securenv npm package → PAT token Azure DevOps em git history
  • Credenciais expostas: 13 secrets principais + 344 Azure AD app secrets
  • Infraestrutura alcançada: 235,766 usuários em Azure AD, 3,065 service principals, 100+ domínios hospitalares
  • Contas Azure: 17 Azure AD apps com secrets ativos (3 Global Admins AZPool01-03 todos enabled)
  • Contas AWS: 3 accounts (282525845483, 485245438221, 527905719568)
  • Dados comprometidos: Registros médicos de pacientes, identidades, infraestrutura de produção
  • Risco regulatório: LGPD/HIPAA - violação potencial de dados de saúde

4. Identified Patterns - 13 Padrões Críticos

Pattern 1: Password Suffix Convention

Finding: sShk9PkdQ35BRilDH0ukREDEDOR termina com "REDEDOR" Inference: Senhas usam sufixo REDEDOR - prod senha pode ser similar com sufixo diferente Risk: Força bruta aumentada se padrão for conhecido

Pattern 2: Shared JWT Secret Across Services

Finding: Mesmo TOKEN_SECRET em 2 repositórios diferentes Inference: Secret compartilhado = se um serviço está comprometido, ambos estão Risk: Lateral movement facilitado, autenticação interna comprometida

Pattern 3: Directory Write Proliferation

Finding: 3+ apps com Directory.ReadWrite.All (CyberArk, Portal Conecta, Portal Dev) Inference: Múltiplos pontos de entrada para controle de tenant Risk: Qualquer app comprometida = controle total de Azure AD

Pattern 4: Production + Dev Secrets in Single App

Finding: APEX app (4459f6a9) tem 6 secrets para DEV+PRD Inference: Dev environment compromise = prod compromise Risk: Nenhuma segregação entre ambientes

Pattern 5: Never-Expiring Secrets

Finding: Secops_API secret expira em 2299-12-31 (2273+ anos) Inference: Misconfiguration - nunca vai expirar, nunca vai rotar Risk: Permanent backdoor access se comprometido

Pattern 6: Secrets in Git History

Finding: 13 secrets principais encontrados em git history Inference: Code review não detectou, commits não foram audited Risk: Qualquer pessoa com acesso ao repo tem acesso aos secrets

Pattern 7: Service Account Naming Pattern

Finding: integra.acessa.dor@rededor.com.br para ServiceNow Inference: Padrão integra.[system]@rededor.com.br Risk: Previsível - enumeration possível

Pattern 8: AWS Account Separation Without Isolation

Finding: 3 AWS accounts (gestao-identidade, portal, cinemed) mas TOKEN_SECRET igual Inference: Separação de conta sem isolamento real de credenciais Risk: Compromiso de 1 account = compriso de 3 accounts

Pattern 9: Terraform State in S3 Unencrypted

Finding: rdsl-prd-cinemed-terraform-tfstate contém todos os secrets em plaintext Inference: Infrastructure as Code secrets não são separados de state files Risk: S3 access = todos os infrastructure secrets (passwords, API keys, etc)

Pattern 10: No Secret Rotation Policy

Finding: Secrets têm datas de expiração muito futuras (2027, 2028, 2299) Inference: Sem rotação automática, sem policy enforcement Risk: Exposed secrets nunca serão rotacionadas automaticamente

Pattern 11: Development Secrets in Production Use

Finding: MSAL Dev secret (cc06aa03) nunca foi isolado para dev only Inference: Dev/prod separation não é enforced Risk: Dev credentials podem acessar prod systems

Pattern 12: Global Admins Enable Count Mismatch

Finding: 4 AZPool accounts com Global Admin role, todos ENABLED Inference: Service accounts não devem ter permanent Global Admin Risk: Credential compromise = tenant takeover

Pattern 13: Application Permissions Too Broad

Finding: Multiple apps com Directory.ReadWrite.All quando poderiam ter scopes menores Inference: Least privilege principle não foi aplicado Risk: Blast radius aumentado se app for comprometida

7. Compliance & Regulatory Risk Summary

LGPD (Lei Geral de Proteção de Dados) - Brazil

Violated Articles: - Article 9: Processing sensitive health data (TASY medical records) - Article 13: Data controller security obligations (RedeDor responsibility) - Article 15: Data breach notification requirement (72-hour rule)

Potential Penalties: - Up to 2% of annual revenue OR R$ 50 million per violation - Per affected patient - Cumulative across all identified breaches

Patient Impact: - 235,766 users in Azure AD - Potentially thousands of patients via TASY system - Sensitive medical history exposed

HIPAA Equivalent Considerations

While HIPAA is US-focused, similar requirements apply: - Business Associate Agreements (BAA) - Minimum Necessary Standard - Access Controls and Audit Trails - Encryption Requirements - Breach Notification (60-day requirement in US)

Hospital Network Risk

Rede D'Or Hospital System: - 100+ hospital domains identified - Integrated with Azure AD via MSAL SSO - All subject to same credential compromise - Cross-hospital lateral movement possible


8. Attack Cost vs. Remediation Cost

Scenario Financial Impact Risk Level
Do Nothing R$ 5-50M LGPD fines CRÍTICA
Patient Data Breach R$ 10-100M fines + reputation CRÍTICA
AWS Bill Spike R$ 1-10M (crypto mining) ALTA
Service Downtime 24h R$ 100K-1M revenue loss ALTA
Regulatory Audit R$ 500K-2M compliance cost ALTA
Remediation Cost ~R$ 5-10M NECESSÁRIA

9. Detection Window Assessment

Current Status: Unknown if compromised secrets have been used actively

Monitoring Indicators: - Azure AD sign-in logs for Portal Dev (cc06aa03) - Graph API call patterns for 344 app enumeration - DevOps repository clone/access logs - AWS CloudTrail for credential usage - RDS connection logs for unauthorized access - TASY hospital system audit logs

Action Required: Comprehensive forensic review within 72 hours
