It writes and executes that payload detached from temporary storage. - **Trigger:** Runtime require/import of index.js. - **Impact:** Arbitrary attacker-controlled native code execution on the importing host. - **Evidence paths:** package.json, index.js, \_compat.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-03T08:44:14.918Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote binary download, temp-file drop, and detached execution. - **Attack narrative:** The main entrypoint catches and suppresses errors while loading \_compat.js. That module retrieves an opaque binary from rotating Workers hosts or DNS TXT chunks, saves it as a hidden cache file or .exe under a temporary directory, sets execute permission on non-Windows systems, and launches it detached via shell/cmd. This occurs merely when the package is imported. - **Rationale:** Confirmed source establishes a concrete, silent remote-payload execution chain reachable from the package entrypoint. The lack of install hooks does not mitigate runtime compromise on import. - **Files touched:** index.js, \_compat.js - **Network endpoints:** oob-worker.cf102-baf.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf99-9b3.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 \_compat.js on every package load., \_compat.js downloads platform binaries from obfuscated Workers hosts., \_compat.js falls back to DNS TXT payload retrieval., \_compat.js writes payload to temp storage, chmods it, then detached-spawns it., No lifecycle hook or user opt-in gates this runtime payload execution. - **Evidence against:** package.json declares no lifecycle scripts., The advertised TokenManager code itself is a simple in-memory token store. ## Public findings ### 1.

Critical: Trigger Reachable Dangerous Capability - **Category:** Source - **Confidence:** 90.0% - **Path:** \_compat.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 -> _compat.js L2: L3: const https = require("https"); L4: const path = require("path"); ...
