It downloads or DNS-reconstructs a platform binary, writes it to temporary storage, and executes it detached. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-05T18:18:07.331Z - **Finished:** 2026-08-05T18:18:30.460Z - **Download time:** 257 ms - **Static scan time:** 27 ms - **AI review time:** 22845 ms - **Total time:** 23129 ms ## Security analysis ### Published attack-surface review - **Summary:** Importing the package automatically launches a concealed remote payload loader. It downloads or DNS-reconstructs a platform binary, writes it to temporary storage, and executes it detached. - **Trigger:** Any runtime require/import of the package entrypoint. - **Impact:** Arbitrary attacker-controlled code executes as the importing process user. - **Evidence paths:** package.json, index.js, \_vendor.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T18:18:30.460Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Import-time remote binary download, drop, chmod, and detached execution. - **Attack narrative:** The main entrypoint silently requires \_vendor.js. Its immediately invoked setup routine selects a platform payload path, retrieves bytes from rotating HTTPS hosts or DNS TXT records, drops them into a temporary executable, and launches them detached through cmd.exe or /bin/sh. This is a concrete import-time remote-code-execution chain, not ordinary telemetry. - **Rationale:** The package contains a concealed, automatic remote binary loader reached from its main entrypoint. No lifecycle hook is needed because normal package import triggers execution. - **Files touched:** index.js, \_vendor.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.cf100-416.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf101-adf.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 \_vendor.js on every package import., \_vendor.js fetches platform binaries from worker hosts., \_vendor.js falls back to DNS TXT payload retrieval from dl.wel1.ru subdomains., Downloaded bytes are written to a temp file, chmodded, and detached-spawned., Execution is automatic at import time and errors are suppressed., A cooldown marker masks repeated execution attempts. - **Evidence against:** package.json contains no npm lifecycle scripts., The exported index API itself is a minimal watchdog wrapper. ## Public findings ### 1. High: Child Process - **Category:** Source - **Confidence:** 85.0% - **Path:** \_vendor.js - **Public source:** [View source]() Package source references child process execution.

Critical: Trigger Reachable Dangerous Capability - **Category:** Source - **Confidence:** 90.0% - **Path:** \_vendor.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 -> _vendor.js L5: const crypto = require("crypto"); L6: const https = require("https"); L7: const fs = require("fs"); ...
