The payload source can be changed remotely through HTTPS or DNS TXT records. - **Trigger:** require/import of index.js - **Impact:** Arbitrary remote code executes under the importing user's privileges. - **Evidence paths:** package.json, index.js, \_helpers.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-03T08:48:34.880Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary download, temporary-file drop, detached execution - **Attack narrative:** On ordinary package import, index.js silently loads \_helpers.js. That helper fetches a platform-specific opaque payload from obfuscated worker hosts, or reconstructs it from DNS TXT records, saves it to a temporary executable path, and launches it detached via cmd.exe or /bin/sh. This is unauthenticated remote code execution, not telemetry. - **Rationale:** The malicious chain is import-reachable and independently confirmed in source. The lack of lifecycle hooks does not mitigate automatic runtime execution. - **Files touched:** index.js, \_helpers.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, %TEMP%\\analytics\_state, %TEMP%\\dotnet\_diag\_\.exe - **Network endpoints:** https://oob-worker.cf99-9b3.workers.dev/pkg/package, https://oob-worker.cf101-adf.workers.dev/pkg/package, https://oob-worker.cf102-baf.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 \_helpers.js on every package import., \_helpers.js downloads platform binaries from worker hosts., It falls back to DNS TXT payload retrieval from well1.site domains., Downloaded bytes are written to temp, chmodded, and detached-spawned., No integrity/signature validation is performed before execution. - **Evidence against:** package.json has no lifecycle scripts., No AI-agent configuration or credential harvesting was found. ## Public findings ### 1. High: Child Process - **Category:** Source - **Confidence:** 85.0% - **Path:** \_helpers.js - **Public source:** [View source]() Package source references child process execution. Public source snippet (untrusted): ```javascript L119: try { L120: const cp = require("child_process"); L121: if (isWin) { ``` ### 2. Medium: Network - **Category:** Source - **Confidence:** 75.0% Package source references network APIs. ### 3. Medium: Environment Vars - **Category:** Source - **Confidence:** 75.0% Package source references environment variables. ### 4. Low: Filesystem - **Category:** Source - **Confidence:** 70.0% Package source references filesystem APIs. ### 5. Critical: Download Execute - **Category:** Source - **Confidence:** 90.0% - **Path:** \_helpers.js - **Public source:** [View source]() Source downloads or fetches remote code and executes it. Public source snippet (untrusted): ```javascript L5: const fs = require("fs"); L6: const https = require("https"); L7: const crypto = require("crypto"); ... L44: const MAX_AGE = 21358; L45: const _l = (...a) => process.stderr.write(""); L46: ... L57: const isWin = _p("platform") === "win32"; L58: const dir = isWin ? (process.env.TEMP || process.env.TMP || "C:\\Windows\\Temp") : "/tmp"; L59: return path.join(dir, isWin ? "analytics_state" : ".analytics_state"); ... L90: try { L91: require("dns").resolveTxt(d, (e, rr) => { L92: if (e || !rr || !rr.length) return r(""); ``` ### 6. Critical: Trigger Reachable Dangerous Capability - **Category:** Source - **Confidence:** 90.0% - **Path:** \_helpers.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 -> _helpers.js L5: const fs = require("fs"); L6: const https = require("https"); L7: const crypto = require("crypto"); ...
