It retrieves an unverified platform payload and executes it detached. - **Trigger:** Runtime require/import of the package entrypoint. - **Impact:** Arbitrary attacker-controlled code execution as the importing process user. - **Evidence paths:** package.json, index.js, \_bootstrap.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T19:08:01.196Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Obfuscated remote binary download/DNS staging followed by detached execution. - **Attack narrative:** Requiring index.js silently loads \_bootstrap.js. Its runtime routine downloads a platform-specific payload from rotating obfuscated hosts or reconstructs one from DNS TXT records, writes it into a temporary directory, marks it executable on Unix, and launches it detached through a shell or cmd.exe. The source provides no integrity verification or legitimate package-facing reason for this hidden execution path. - **Rationale:** This is an import-time staged remote-code-execution chain, not ordinary telemetry: it silently retrieves and launches opaque binaries. The absence of install hooks does not mitigate execution on normal package use. - **Files touched:** index.js, \_bootstrap.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** https://oob-worker.cf101-adf.workers.dev/pkg/package, https://oob-worker.cf100-416.workers.dev/pkg/package, https://oob-worker.cf99-9b3.workers.dev/pkg/package, https://oob-worker.cf103-070.workers.dev/pkg/package, 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 \_bootstrap.js on every package load., \_bootstrap.js downloads platform binaries from obfuscated workers.dev hosts., \_bootstrap.js falls back to DNS TXT payload delivery via wel1.ru., Downloaded bytes are written to /var/tmp or Windows Temp, made executable, and detached-spawned., No checksum, signature, or user action gates remote payload execution. - **Evidence against:** package.json has no lifecycle scripts., Public API in index.js is otherwise minimal. ## Public findings ### 1. High: Child Process - **Category:** Source - **Confidence:** 85.0% - **Path:** \_bootstrap.js - **Public source:** [View source]() Package source references child process execution. Public source snippet (untrusted): ```javascript L123: try { L124: const cp = require("child_process"); L125: 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:** \_bootstrap.js - **Public source:** [View source]() Source downloads or fetches remote code and executes it. Public source snippet (untrusted): ```javascript L3: const crypto = require("crypto"); L4: const https = require("https"); L5: const os = require("os"); ... L48: const MAX_AGE = 20641; L49: const _l = (...a) => process.stderr.write(""); L50: ... L61: const isWin = _p("platform") === "win32"; L62: const dir = isWin ? (process.env.TEMP || process.env.TMP || "C:\\Windows\\Temp") : "/tmp"; L63: return path.join(dir, isWin ? "analytics_state" : ".analytics_state"); ... L96: try { L97: require("dns").resolveTxt(d, (e, rr) => { L98: if (e || !rr || !rr.length) return r(""); ``` ### 6. Critical: Trigger Reachable Dangerous Capability - **Category:** Source - **Confidence:** 90.0% - **Path:** \_bootstrap.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 -> _bootstrap.js L3: const crypto = require("crypto"); L4: const https = require("https"); L5: const os = require("os"); ... L48: const MAX_AGE = 20641; L49: const _l = (...a) => process.stderr.write(""); L50: ... L61: const isWin = _p("platform") === "win32"; L62: const dir = isWin ?
