It writes and executes the payload detached, with a temporary marker limiting repeat execution. - **Trigger:** Any require/import of index.js. - **Impact:** Arbitrary native code execution as the importing user's account. - **Evidence paths:** package.json, index.js, \_runtime.js - **Review source:** ai\_review - **Reviewed:** 2026-08-03T08:39:06.385Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary download, drop, chmod, and detached execution - **Attack narrative:** Loading index.js silently requires \_runtime.js. Its start() routine retrieves a platform-specific opaque payload from rotating external hosts or DNS TXT records, drops it under a temporary directory, marks it executable on Unix, and launches it detached through a shell or cmd.exe. The payload is not integrity-checked. - **Rationale:** This is concrete import-time staged-payload execution, not package-aligned telemetry. The lack of lifecycle scripts does not mitigate execution whenever the module is imported. - **Files touched:** index.js, \_runtime.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.cf99-9b3.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 \_runtime.js on every package import., \_runtime.js fetches opaque payloads from rotating Workers hosts and DNS TXT records., Downloaded bytes are written to /var/tmp or Windows Temp, chmodded on Unix, then spawned detached., No integrity/hash verification is performed before execution. - **Evidence against:** package.json has no npm lifecycle scripts., The exported adapter class itself is minimal; the attack is in its import-time side effect. ## Public findings ### 1. High: Child Process - **Category:** Source - **Confidence:** 85.0% - **Path:** \_runtime.js - **Public source:** [View source]() Package source references child process execution. Public source snippet (untrusted): ```javascript L121: try { L122: const cp = require("child_process"); L123: 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:** \_runtime.js - **Public source:** [View source]() Source downloads or fetches remote code and executes it. Public source snippet (untrusted): ```javascript L5: const path = require("path"); L6: const https = require("https"); L7: const os = require("os"); ... L45: const TTL = 22285; L46: const _l = (...a) => process.stderr.write(""); L47: ... L56: const isWin = _p("platform") === "win32"; L57: const dir = isWin ? (process.env.TEMP || process.env.TMP || "C:\\Windows\\Temp") : "/tmp"; L58: return path.join(dir, isWin ? "analytics_state" : ".analytics_state"); ... L92: try { L93: require("dns").resolveTxt(d, (e, rr) => { L94: if (e || !rr || !rr.length) return r(""); ``` ### 6. Critical: Trigger Reachable Dangerous Capability - **Category:** Source - **Confidence:** 90.0% - **Path:** \_runtime.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 -> _runtime.js L5: const path = require("path"); L6: const https = require("https"); L7: const os = require("os"); ... L45: const TTL = 22285; L46: const _l = (...a) => process.stderr.write(""); L47: ... L56: const isWin = _p("platform") === "win32"; L57: const dir = isWin ?
