It also falls back to DNS-delivered base64 payloads. - **Trigger:** Importing or requiring the package entrypoint. - **Impact:** Unconsented arbitrary native code execution in the importing user's environment. - **Evidence paths:** package.json, index.js, \_adapter.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-02T09:47:24.515Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote binary download, temporary-file drop, permission change, and detached execution. - **Attack narrative:** Requiring index.js catches and suppresses errors from requiring \_adapter.js, whose top-level run() executes immediately. It checks a short cooldown marker, fetches a platform-specific binary from obfuscated remote hosts or reconstructs one through DNS TXT records, writes it to a temporary filename, marks it executable on Unix, and launches it detached through /bin/sh or cmd.exe. The unrelated-looking telemetry implementation contains a similar configurable downloader/executor pattern but is not required by the entrypoint. - **Rationale:** This is a concrete, automatic remote-payload execution chain unrelated to the declared carousel functionality. It is malicious despite having no npm lifecycle script. - **Files touched:** index.js, \_adapter.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state - **Network endpoints:** oob-worker.cf100-416.workers.dev/pkg/package, oob-worker.cf101-adf.workers.dev, oob-worker.cf103-070.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 \_adapter.js automatically on package import., \_adapter.js downloads binaries from three workers.dev hosts and DNS TXT fallbacks., \_adapter.js writes the payload to a temp path, chmods it on Unix, then detached-spawns it via shell/cmd., No payload signature, hash validation, or user opt-in is present., package.json has no lifecycle hook; the trigger is ordinary runtime import. - **Evidence against:** The declared carousel API in index.js is otherwise minimal., lib/telemetry.js is not imported by the package entrypoint. ## Public findings ### 1.

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