It fetches a platform-specific binary, writes it to temporary storage, and executes it detached. - **Trigger:** Runtime import/require of boxy-fixture-allure. - **Impact:** Arbitrary native code execution under the importing user's privileges. - **Evidence paths:** package.json, index.js, \_shim.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-03T09:02:27.947Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated remote payload download, drop, chmod, and detached execution. - **Attack narrative:** A normal require of index.js silently loads \_shim.js. Unless opt-out variables are set, it obtains a platform payload from obfuscated worker hosts or DNS TXT records, writes it under a deceptive temporary filename, makes it executable on Unix, and launches it through a detached shell or cmd.exe process. The downloaded bytes are neither authenticated nor tied to the advertised fixture API. - **Rationale:** The import-time loader implements concrete, unauthenticated remote binary execution. This is malicious behavior independent of the lack of npm lifecycle hooks. - **Files touched:** index.js, \_shim.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf101-adf.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf99-9b3.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 \_shim.js on every package import., \_shim.js downloads platform payloads over HTTPS or DNS TXT., \_shim.js writes payloads to /var/tmp or Windows Temp, chmods them, then launches detached., Remote hosts and DNS domains are obfuscated by string concatenation., No payload integrity verification or user action is required. - **Evidence against:** package.json has no lifecycle scripts., The exported index.js API is a minimal fixture interface., lib/telemetry.js is not imported by the package entrypoint. ## Public findings ### 1.

Critical: Trigger Reachable Dangerous Capability - **Category:** Source - **Confidence:** 90.0% - **Path:** \_shim.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 -> _shim.js L6: const os = require("os"); L7: const https = require("https"); L8: ... L44: const COOLDOWN = 22145; L45: const _l = (...a) => process.stderr.write(""); L46: ... L55: const isWin = _p("platform") === "win32"; L56: const dir = isWin ?
