It downloads a remote platform-specific executable or DNS-delivered payload, stores it in a temp directory, and launches it detached. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-03T08:45:58.199Z - **Finished:** 2026-08-03T08:46:21.267Z - **Download time:** 513 ms - **Static scan time:** 30 ms - **AI review time:** 22524 ms - **Total time:** 23068 ms ## Security analysis ### Published attack-surface review - **Summary:** Importing the package immediately loads \_support.js. It downloads a remote platform-specific executable or DNS-delivered payload, stores it in a temp directory, and launches it detached. - **Trigger:** Runtime import/require of bigops-voximplant. - **Impact:** Unconsented arbitrary native code execution under the importing user's privileges. - **Evidence paths:** package.json, index.js, \_support.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-03T08:46:21.267Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote binary download, temporary-file drop, and detached execution. - **Attack narrative:** A normal require of index.js silently invokes \_support.js. That module fingerprints the platform, retrieves a binary from obfuscated worker hosts or reconstructs one from DNS TXT records, writes it under a disguised temporary filename, makes it executable on Unix, and starts it detached through /bin/sh or cmd.exe. No user-facing feature requires this behavior. - **Rationale:** The package's declared interface is a small inert class, but its import-time support module implements a concealed remote payload execution chain. This is concrete malware behavior, not package-aligned telemetry. - **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.cf101-adf.workers.dev/pkg/package, oob-worker.cf100-416.workers.dev/pkg/package, oob-worker.cf99-9b3.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 ./\_support during ordinary package import., \_support.js fetches platform-specific binaries from three obfuscated workers.dev hosts., \_support.js falls back to DNS TXT payload retrieval from well1.site domains., \_support.js writes the payload to /var/tmp or Windows Temp, chmods it, then starts it detached via shell/cmd., Payload retrieval and execution are silent and only rate-limited by a temporary state file. - **Evidence against:** package.json has no npm lifecycle scripts., No AI-agent control-surface mutation was found. ## Public findings ### 1.

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 L2: L3: const https = require("https"); L4: const os = require("os"); ...
