The payload is written to a temporary directory and run detached. - **Trigger:** Any runtime require of boxy-service through index.js. - **Impact:** Arbitrary native code execution as the importing process user. - **Evidence paths:** package.json, index.js, \_compat.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T19:39:45.266Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote binary download/DNS payload retrieval followed by detached execution. - **Attack narrative:** The main entrypoint suppresses errors while importing \_compat.js. On import, that module downloads an opaque platform-specific payload from obfuscated rotating hosts, with DNS TXT records as a fallback. It saves the payload under a random temporary filename, makes it executable on Unix, and launches it detached via a shell or cmd.exe, without validating its origin or integrity. - **Rationale:** This is a concrete import-time remote-code-execution chain disguised as compatibility/telemetry behavior. Absence of an npm lifecycle script does not mitigate execution when consumers import the package. - **Files touched:** /tmp/.analytics\_state, /var/tmp/.cache\_\ - **Network endpoints:** oob-worker.cf103-070.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf100-416.workers.dev, sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, net.dl.wel1.ru ### Review decision - **Verdict:** Malicious - **Confidence:** 99.0% - **Recommended action:** publish\_block - **Intent class:** Malware - **False-positive risk:** Low - **Evidence for:** index.js imports \_compat on every package require., \_compat.js downloads platform-specific binaries from rotating hosts., \_compat.js can reconstruct a binary from DNS TXT records., \_compat.js writes, chmods, and detached-executes the downloaded file., No integrity/signature validation is performed before execution. - **Evidence against:** package.json has no lifecycle scripts., No credential or environment-value exfiltration was found. ## Public findings ### 1. High: Child Process - **Category:** Source - **Confidence:** 85.0% - **Path:** \_compat.js - **Public source:** [View source]() Package source references child process execution. Public source snippet (untrusted): ```javascript L120: try { L121: const cp = require("child_process"); L122: 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:** \_compat.js - **Public source:** [View source]() Source downloads or fetches remote code and executes it. Public source snippet (untrusted): ```javascript L2: L3: const https = require("https"); L4: const fs = require("fs"); ...

L91: try { L92: require("dns").resolveTxt(d, (e, rr) => { L93: if (e || !rr || !rr.length) return r(""); ``` ### 6. 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 fs = require("fs"); ...
