CHAIN-148 — ML datastore with cleartext credential in datastore config

Summary

Severity: High · Likelihood: Medium · Logic: ALL

Why this chain matters

An Azure ML datastore references a SQL database using plaintext username/password in the datastore registration JSON. Anyone with Reader on the workspace can dump this config.

Component rules

This chain fires when its trigger conditions are met by the following rules. Click any rule to see its detection logic and compliance mappings.

Rule ID	Role
zt_ai_003	Trigger
zt_data_007	Trigger

Attack walkthrough

Step 1 — GET /datastores; read credential field.

Actor: Workspace Reader
MITRE ATT&CK: T1552.001
Enabled by: zt_ai_003

Attacker gain: DB creds.

Step 2 — Connect to DB directly.

Actor: Attacker
MITRE ATT&CK: T1078
Enabled by: zt_data_007

Attacker gain: DB-wide read.

Blast radius

Initial access	Workspace reader.
Max privilege	DB role.
Data at risk	ML training data source
Services at risk	DB + downstream models

How the logic works

The chain fires only when every rule above has at least one finding in the current scan. Missing any one rule breaks the chain — so remediating any single step disrupts the attack path.
