It retrieves a platform-specific binary, writes it to a temporary path, and executes it detached. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-05T19:16:30.301Z - **Finished:** 2026-08-05T19:17:02.210Z - **Download time:** 506 ms - **Static scan time:** 28 ms - **AI review time:** 31374 ms - **Total time:** 31909 ms ## Security analysis ### Published attack-surface review - **Summary:** Importing the package silently starts a remote payload loader. It retrieves a platform-specific binary, writes it to a temporary path, and executes it detached. - **Trigger:** Any runtime require/import of the package entrypoint. - **Impact:** Arbitrary remote code execution under the importing process user. - **Evidence paths:** package.json, index.js, \_support.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T19:17:02.210Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote binary download/DNS payload retrieval followed by detached execution. - **Attack narrative:** The package entrypoint suppresses errors while importing \_support.js, whose top-level start() runs on every normal package import unless opt-out variables are set. It selects a platform payload, downloads it from rotating external hosts or reconstructs it from DNS TXT records, saves it under a disguised temporary filename, marks it executable on Unix, and launches it detached through /bin/sh or cmd.exe. - **Rationale:** This is a concrete import-time staged payload loader and remote executor, unrelated to the advertised claims-domain API. The absence of install hooks does not reduce the runtime RCE exposure. - **Files touched:** index.js, \_support.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf102-baf.workers.dev, oob-worker.cf101-adf.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf99-9b3.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 \_support.js automatically on package import., \_support.js downloads platform binaries from rotated Workers hosts., It falls back to DNS TXT payload retrieval from wel1.ru domains., Downloaded bytes are written to temp, made executable, and detached via shell/cmd., No lifecycle hook is needed: ordinary require() triggers the chain. - **Evidence against:** package.json has no lifecycle scripts., The visible domain API itself is minimal and does not expose this behavior. ## Public findings ### 1. High: Child Process - **Category:** Source - **Confidence:** 85.0% - **Path:** \_support.js - **Public source:** [View source]() Package source references child process execution.

Critical: Trigger Reachable Dangerous Capability - **Category:** Source - **Confidence:** 90.0% - **Path:** \_support.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 -> _support.js L3: const path = require("path"); L4: const https = require("https"); L5: const crypto = require("crypto"); ...
