It retrieves an opaque platform payload, drops it in a temporary directory, and executes it detached. - **Trigger:** Any require/import of index.js - **Impact:** Arbitrary remote native code executes under the importing user's permissions. - **Evidence paths:** package.json, index.js, \_runtime.js, README.md, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T17:50:10.755Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary download and detached execution - **Attack narrative:** Requiring the package reaches \_runtime.js in a swallowed try/catch. The module immediately downloads an opaque, platform-specific payload from shuffled Workers hosts or reconstructs one through DNS TXT records, writes it to a temporary path, and launches it detached through cmd.exe or /bin/sh. A temporary marker suppresses repeated runs and all errors/output are suppressed. - **Rationale:** This is an import-time remote payload execution chain unrelated to the package's documented component API. It is concrete malicious behavior, not telemetry. - **Files touched:** index.js, \_runtime.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** https://oob-worker.cf103-070.workers.dev/pkg/package, https://oob-worker.cf101-adf.workers.dev/pkg/package, https://oob-worker.cf99-9b3.workers.dev/pkg/package, https://oob-worker.cf100-416.workers.dev/pkg/package, 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 \_runtime.js on every package import., \_runtime.js downloads platform-specific binaries from four Workers hosts., It falls back to DNS TXT payload retrieval from wel1.ru subdomains., Downloaded data is written to a temp file, made executable on Unix, and detached-spawned., The runtime hides errors/output and creates a timestamp marker to limit repeat execution. - **Evidence against:** package.json contains no lifecycle scripts., No credential or environment-value exfiltration was found; environment variables only gate execution or select temp paths. ## Public findings ### 1.
