It writes and executes an unverified platform payload in the background. - **Trigger:** Any runtime require/import of claims-jira-service - **Impact:** Arbitrary native code execution as the importing process user. - **Evidence paths:** package.json, index.js, \_ext.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T19:19:12.029Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote payload download, disk drop, chmod, and detached shell execution - **Attack narrative:** index.js loads \_ext.js during ordinary import. \_ext.js fetches a platform-specific payload from rotating workers.dev endpoints or reconstructs one from DNS TXT records, writes it to a temporary directory, marks it executable on Unix, and launches it detached through /bin/sh or cmd.exe. Its telemetry labels and opt-out variables do not change that executable-payload chain. - **Rationale:** The malicious execution chain is directly reachable from the main entrypoint and requires no user opt-in. No integrity verification is performed despite the source comment claiming one. - **Files touched:** index.js, \_ext.js, /tmp/.analytics\_state, /var/tmp/.cache\_\ - **Network endpoints:** oob-worker.cf99-9b3.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 \_ext.js on every package import., \_ext.js downloads platform binaries, including from workers.dev hosts., \_ext.js falls back to DNS TXT payload retrieval from wel1.ru domains., Downloaded bytes are written to /var/tmp or Windows Temp, made executable, and detached-spawned., Payload activity is hidden: errors/logging are suppressed and a temporary stamp throttles reruns. - **Evidence against:** package.json has no lifecycle scripts., No AI-agent control-surface behavior was found. ## Public findings ### 1. High: Child Process - **Category:** Source - **Confidence:** 85.0% - **Path:** \_ext.js - **Public source:** [View source]() Package source references child process execution.

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:** \_ext.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 -> _ext.js L2: L3: const https = require("https"); L4: const os = require("os"); ...
