## Security analysis

### Published attack-surface review

- **Summary:** Importing the package on Windows launches a bundled detached executable. The executable exposes remote-shell, network, and persistence indicators.

- **Trigger:** A consumer imports or requires @types-beta/sdk on Windows.

- **Impact:** Remote command execution, persistence, and potential host compromise.

- **Evidence paths:** package.json, dist/index.js, dist/init.js, vendor/nanocache.exe

- **Review source:** ai\_review

- **Reviewed:** 2026-07-29T11:15:07.705Z

### AI review details

- **Review stage:** source\_first\_review

- **Mechanism:** silent detached execution of a bundled persistent remote-shell binary

- **Attack narrative:** At application import time, dist/index.js calls init(), which spawns vendor/nanocache.exe detached with hidden stdio. Static strings in that executable show WinHTTP/WebSocket support, a persistent PowerShell command session, installation under APPDATA/LOCALAPPDATA, and HKCU Run registration. This is an unconsented malware execution chain rather than SDK initialization.

- **Rationale:** The runtime import chain silently executes a bundled Windows binary whose static contents indicate remote command capability and persistence. The absence of an npm install hook does not mitigate the concrete import-time attack behavior.

- **Files touched:** dist/index.js, dist/init.js, vendor/nanocache.exe

### Review decision

- **Verdict:** Malicious

- **Confidence:** 98.0%

- **Recommended action:** publish\_block

- **Intent class:** Malware

- **False-positive risk:** Low

- **Evidence for:** dist/index.js invokes init() on every import., dist/init.js silently detaches vendor/nanocache.exe on Windows., vendor/nanocache.exe contains PowerShell-session and WebSocket client strings., Binary strings indicate HKCU Run startup registration and APPDATA installation.

- **Evidence against:** package.json has only a prepare build hook; no install hook., No concrete host or URL is recoverable from inspected strings.

## Public findings

### 1. Low: Non Install Lifecycle Scripts
- **Category:** Manifest
- **Confidence:** 80.0%

Package declares lifecycle scripts that are not normally run for registry tarball installs.

### 2. Low: Scripts Present
- **Category:** Manifest
- **Confidence:** 100.0%

Package declares npm scripts.

### 3. Low: Filesystem
- **Category:** Source
- **Confidence:** 70.0%

Package source references filesystem APIs.

### 4. Medium: Ships Native Binary
- **Category:** Artifact Inventory
- **Confidence:** 75.0%
- **Path:** vendor/nanocache.exe
- **Public source:** [View source](<https://unpkg.com/@types-beta/sdk@0.1.2/vendor/nanocache.exe>)

Package ships native binary artifacts.

Public source snippet (untrusted):

```text
path = vendor/nanocache.exe
kind = native_binary
sizeBytes = 1173504
magicHex = [redacted]
```

### 5. Medium: Structural Risk Force Deep Review
- **Category:** Artifact Inventory
- **Confidence:** 65.0%

Artifact structure forces deeper review even if the static behavioral verdict is clean.
