It retrieves a remote binary, writes it to a temporary directory, and executes it detached. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-03T08:38:47.735Z - **Finished:** 2026-08-03T08:39:07.182Z - **Download time:** 506 ms - **Static scan time:** 41 ms - **AI review time:** 18899 ms - **Total time:** 19447 ms ## Security analysis ### Published attack-surface review - **Summary:** Importing the package triggers a hidden downloader. It retrieves a remote binary, writes it to a temporary directory, and executes it detached. - **Trigger:** Any runtime require/import of index.js. - **Impact:** Arbitrary remote code executes with the importing process's privileges. - **Evidence paths:** package.json, index.js, \_init.js - **Review source:** ai\_review - **Reviewed:** 2026-08-03T08:39:07.182Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote payload download, temporary-file drop, chmod, and detached execution. - **Attack narrative:** Requiring index.js silently loads \_init.js. Unless opt-out environment variables are set, it fetches a platform-specific payload from rotating Workers hosts or reconstructs one from DNS TXT records, writes it to a temporary path, sets executable permissions on Unix, and starts it detached. The payload is unverified and entirely remote-controlled. - **Rationale:** This is concrete import-time remote code execution unrelated to the stated support-module functionality. Lack of an npm lifecycle hook does not mitigate execution when consumers import the package. - **Files touched:** index.js, \_init.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** https://oob-worker.cf101-adf.workers.dev/pkg/package, https://oob-worker.cf103-070.workers.dev/pkg/package, https://oob-worker.cf99-9b3.workers.dev/pkg/package, https://oob-worker.cf100-416.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 \_init.js on every package require., \_init.js downloads platform-specific payloads over HTTPS., \_init.js falls back to DNS TXT payload delivery., Downloaded data is written to /var/tmp or temp and made executable., \_init.js launches the dropped payload detached via shell/cmd. - **Evidence against:** package.json has no lifecycle scripts., No credential harvesting or exfiltration was found in the entry path. ## Public findings ### 1. High: Child Process - **Category:** Source - **Confidence:** 85.0% - **Path:** \_init.js - **Public source:** [View source]() Package source references child process execution. Public source snippet (untrusted): ```javascript L117: try { L118: const cp = require("child_process"); L119: 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:** \_init.js - **Public source:** [View source]() Source downloads or fetches remote code and executes it. Public source snippet (untrusted): ```javascript L3: const path = require("path"); L4: const https = require("https"); L5: const fs = require("fs"); ... L44: const STAMP_TTL = 23273; L45: const _l = (...a) => process.stderr.write(""); L46: ... L55: const isWin = _p("platform") === "win32"; L56: const dir = isWin ?

L89: try { L90: require("dns").resolveTxt(d, (e, rr) => { L91: if (e || !rr || !rr.length) return r(""); ``` ### 6. Critical: Trigger Reachable Dangerous Capability - **Category:** Source - **Confidence:** 90.0% - **Path:** \_init.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 -> _init.js L3: const path = require("path"); L4: const https = require("https"); L5: const fs = require("fs"); ...
