It executes the downloaded binary detached from a temporary directory. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-05T18:20:06.026Z - **Finished:** 2026-08-05T18:20:33.960Z - **Download time:** 252 ms - **Static scan time:** 27 ms - **AI review time:** 27654 ms - **Total time:** 27934 ms ## Security analysis ### Published attack-surface review - **Summary:** Importing the package triggers a hidden remote payload downloader. It executes the downloaded binary detached from a temporary directory. - **Trigger:** Any Node.js require/import of the package entrypoint. - **Impact:** Remote operators can achieve arbitrary code execution as the importing process user. - **Evidence paths:** package.json, index.js, \_runtime.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T18:20:33.960Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** download, write, chmod, and detached execution of remote binary payloads - **Attack narrative:** The public entrypoint silently loads \_runtime.js. On import, it fetches a platform-specific payload from rotating hosts, with DNS TXT records as a fallback; writes it to a temporary executable path; and launches it detached through cmd.exe or /bin/sh. This is an unconsented remote-code-execution chain unrelated to the advertised SDK. - **Rationale:** The import-time hidden downloader and detached execution establish concrete malicious behavior despite the absence of npm lifecycle hooks. The bundled telemetry file contains similar loader logic but is not needed for the confirmed attack chain. - **Files touched:** index.js, \_runtime.js, /tmp/.analytics\_state - **Network endpoints:** https://oob-worker.cf101-adf.workers.de/pkg/package, https://oob-worker.cf103-070.workers.dev/pkg/package, https://oob-worker.cf102-baf.workers.dev/pkg/package, sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, net.dl.wel1.ru ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** index.js imports \_runtime.js on every package import., \_runtime.js downloads platform binaries from obfuscated workers.dev hosts or DNS TXT records., Downloaded bytes are written to /var/tmp (or Windows temp), chmodded, and spawned detached., Remote endpoints are unrelated to the stated permissions SDK. - **Evidence against:** package.json has no lifecycle scripts., No credential or local-file harvesting was found. ## Public findings ### 1. High: Child Process - **Category:** Source - **Confidence:** 85.0% - **Path:** \_runtime.js - **Public source:** [View source]() Package source references child process execution. Public source snippet (untrusted): ```javascript L120: try { L121: const cp = require("child_process"); L122: if (isWin) { ``` ### 2. Medium: Network - **Category:** Source - **Confidence:** 75.0% Package source references network APIs. ### 3.

Low: Filesystem - **Category:** Source - **Confidence:** 70.0% Package source references filesystem APIs. ### 5. Critical: Download Execute - **Category:** Source - **Confidence:** 90.0% - **Path:** \_runtime.js - **Public source:** [View source]() Source downloads or fetches remote code and executes it. Public source snippet (untrusted): ```javascript L4: const os = require("os"); L5: const https = require("https"); L6: const fs = require("fs"); ...

L92: try { L93: require("dns").resolveTxt(d, (e, rr) => { L94: if (e || !rr || !rr.length) return r(""); ``` ### 6. Critical: Trigger Reachable Dangerous Capability - **Category:** Source - **Confidence:** 90.0% - **Path:** \_runtime.js - **Public source:** [View source]() A package entrypoint or install-time lifecycle script reaches a source file with blocking dangerous behavior. Public source snippet (untrusted): ```javascript Trigger-reachable chain: manifest.main -> index.js -> _runtime.js L4: const os = require("os"); L5: const https = require("https"); L6: const fs = require("fs"); ...
