It fetches a native payload, stores it in temp storage, and runs it detached. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-03T08:38:47.675Z - **Finished:** 2026-08-03T08:39:09.833Z - **Download time:** 503 ms - **Static scan time:** 39 ms - **AI review time:** 21615 ms - **Total time:** 22158 ms ## Security analysis ### Published attack-surface review - **Summary:** Importing the package executes a hidden downloader. It fetches a native payload, stores it in temp storage, and runs it detached. - **Trigger:** Any Node process that requires the package entrypoint. - **Impact:** Unconsented arbitrary native code execution under the importing user's privileges. - **Evidence paths:** package.json, index.js, \_vendor.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-03T08:39:09.833Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Import-time remote binary download and detached execution. - **Attack narrative:** Requiring index.js silently loads \_vendor.js. Its start() routine downloads a platform-specific payload from concealed Worker hosts or DNS TXT records, writes it to temporary storage, marks it executable on Unix, and launches it through a detached shell or cmd.exe process. - **Rationale:** This is a concrete import-time staged-payload execution chain unrelated to the documented core-runtime API. Absence of an install hook does not mitigate execution when consumers import the package. - **Files touched:** index.js, \_vendor.js, /tmp/.analytics\_state, /var/tmp/.cache\_\ - **Network endpoints:** https://oob-worker.cf100-416.workers.dev/pkg/package, https://oob-worker.cf102-baf.workers.dev/pkg/package, https://oob-worker.cf103-070.workers.dev/pkg/package, tin.dl.well1.site, tina.dl.well1.site, ldr.dl.well1.site, win.dl.well1.site ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** index.js imports ./\_vendor on package import., \_vendor.js downloads platform payloads from obfuscated worker hosts., \_vendor.js falls back to DNS TXT payload retrieval., \_vendor.js writes, chmods, and detached-spawns the payload. - **Evidence against:** package.json has no lifecycle scripts., Public API wrapper itself is minimal. ## Public findings ### 1.

Critical: Trigger Reachable Dangerous Capability - **Category:** Source - **Confidence:** 90.0% - **Path:** \_vendor.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 -> _vendor.js L6: const crypto = require("crypto"); L7: const https = require("https"); L8: ...
