Testing Methodology
Validate this detection against 4 adversary techniques from Atomic Red Team. Each test below lists the behaviour to exercise and the telemetry you should expect to see. Executable commands and cleanup steps are available with Pro.
- Test 1Shopper RBAC Bypass — Escalate to Admin via Team Settings API
Expected signal: HTTP POST to /api/teams/1/members with 200/201 response code from a low-privileged account; database INSERT into team_user or role_user table with admin role association
- Test 2Shopper RBAC Bypass — Modify Existing Team Member Role to Admin
Expected signal: HTTP PATCH to /api/teams/1/members/{id} returning 200 from a non-admin session token; corresponding UPDATE in the role_user or team_user database table
- Test 3Shopper RBAC Bypass — Create New Admin Account via Team Invitation
Expected signal: HTTP POST to /api/teams/1/invitations with admin role returning 200/201 from low-privileged token; invitation record created in database with role=admin; email delivery event to attacker-controlled address
- Test 4Shopper RBAC Bypass — Enumerate Team Permissions and Extract Sensitive Data
Expected signal: Multiple GET requests to admin-restricted endpoints (/api/teams, /api/settings, /api/orders) returning 200 from a recently-escalated non-admin account; unusual access pattern to sensitive data endpoints
