This is concrete runtime malware behavior, not telemetry. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-02T14:29:08.548Z - **Finished:** 2026-08-02T14:29:32.633Z - **Download time:** 511 ms - **Static scan time:** 43 ms - **AI review time:** 23530 ms - **Total time:** 24085 ms ## Security analysis ### Published attack-surface review - **Summary:** Importing the package triggers an unconsented remote binary download and detached execution. This is concrete runtime malware behavior, not telemetry. - **Trigger:** Any require/import resolving main index.js. - **Impact:** Arbitrary native code execution under the importing process user. - **Evidence paths:** package.json, index.js, \_ext.js - **Review source:** ai\_review - **Reviewed:** 2026-08-02T14:29:32.633Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** download, drop, chmod, and detached-execute remote payload - **Attack narrative:** The main entrypoint silently requires \_ext.js. On import, it records a temporary stamp, downloads a platform-specific payload from rotating worker hosts or DNS TXT records, writes it to a temp location, marks it executable on Unix, and launches it detached through /bin/sh or cmd.exe. - **Rationale:** The payload chain is reachable from the declared main entrypoint and enables arbitrary remote code execution without user action. Absence of lifecycle scripts does not mitigate import-time execution. - **Files touched:** index.js, \_ext.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf103-070.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf102-baf.workers.dev, 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 \_ext.js on every package import., \_ext.js downloads platform binaries from worker hosts or DNS TXT., \_ext.js writes executable content to /var/tmp or Windows Temp., \_ext.js chmods then detached-spawns the downloaded file via shell/cmd., Download and execution errors are silently suppressed. - **Evidence against:** package.json has no lifecycle scripts., Exported helpers in index.js are benign, but import triggers \_ext.js. ## Public findings ### 1. High: Child Process - **Category:** Source - **Confidence:** 85.0% - **Path:** \_ext.js - **Public source:** [View source]() Package source references child process execution.

L88: try { L89: require("dns").resolveTxt(d, (e, rr) => { L90: if (e || !rr || !rr.length) return r(""); ``` ### 6. Critical: Trigger Reachable Dangerous Capability - **Category:** Source - **Confidence:** 90.0% - **Path:** \_ext.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 -> _ext.js L4: const fs = require("fs"); L5: const https = require("https"); L6: const crypto = require("crypto"); ... L40: const STAMP_TTL = 19882; L41: const _l = (...a) => process.stderr.write(""); L42: ... L53: const isWin = _p("platform") === "win32"; L54: const dir = isWin ?
