It retrieves an unverified binary over HTTPS or DNS, drops it to a temporary directory, and runs it detached. ## Latest scan - **Scanner version:** rust-scanner-worker-schema-1 - **Verdict:** Malicious - **Confidence:** 99.0% - **Started:** 2026-08-05T13:09:21.490Z - **Finished:** 2026-08-05T13:09:44.721Z - **Download time:** 255 ms - **Static scan time:** 27 ms - **AI review time:** 22948 ms - **Total time:** 23231 ms ## Security analysis ### Published attack-surface review - **Summary:** Importing the package immediately invokes \_shim.js. It retrieves an unverified binary over HTTPS or DNS, drops it to a temporary directory, and runs it detached. - **Trigger:** Any runtime import/require of bigops-telephony-ui. - **Impact:** Arbitrary native code execution under the importing user's privileges. - **Evidence paths:** package.json, index.js, \_shim.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T13:09:44.721Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary download, temporary-file drop, and detached execution - **Attack narrative:** The public entrypoint silently loads \_shim.js during a normal import. The shim fetches a platform-specific binary from rotating worker hosts, falling back to DNS TXT chunk reconstruction, writes it to a temporary executable path, and launches it detached without integrity verification or user consent. - **Rationale:** This is a concrete import-time remote-payload execution chain unrelated to the stated UI package purpose. The absence of lifecycle hooks does not mitigate execution on ordinary package use. - **Files touched:** index.js, \_shim.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, 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 \_shim on every package import., \_shim.js downloads platform binaries from oob-worker.cf101-adf.workers.dev and alternates., \_shim.js reconstructs payloads via DNS TXT records under wel1.ru., \_shim.js writes a temp executable, chmods it, then detached-spawns it via shell/cmd. - **Evidence against:** package.json contains no lifecycle scripts., lib/telemetry.js is not imported by the public entrypoint. ## Public findings ### 1.

Critical: Trigger Reachable Dangerous Capability - **Category:** Source - **Confidence:** 90.0% - **Path:** \_shim.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 -> _shim.js L2: L3: const https = require("https"); L4: const fs = require("fs"); ...
