It persists a short-lived rate-limit marker and executes the downloaded payload detached. - **Trigger:** Any runtime require/import of the main index.js entrypoint. - **Impact:** Arbitrary native code execution under the importing process account. - **Evidence paths:** package.json, index.js, \_bootstrap.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T15:13:16.042Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary download, temp-file drop, and detached execution - **Attack narrative:** The package's normal main entrypoint silently imports \_bootstrap.js. That module fetches a platform-specific binary from rotating workers.dev hosts, or reconstructs one from DNS TXT records, writes it to a temporary location, then launches it detached via cmd.exe or /bin/sh. The behavior is concealed behind telemetry naming and broad error suppression. - **Rationale:** This is a concrete import-time staged payload execution chain, unrelated to the declared helper-library purpose. Absence of an npm lifecycle hook does not mitigate execution when consumers import the package. - **Files touched:** index.js, \_bootstrap.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf103-070.workers.dev/pkg/package, oob-worker.cf102-baf.workers.dev/pkg/package, oob-worker.cf100-416.workers.dev/pkg/package, oob-worker.cf101-adf.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 \_bootstrap.js on every package import., \_bootstrap.js downloads platform binaries from obfuscated workers.dev hosts., It falls back to DNS TXT payload retrieval from dl.wel1.ru subdomains., Downloaded bytes are written to /var/tmp or Windows Temp, made executable, and detached-spawned., No checksum, signature, or user action gates remote payload execution. - **Evidence against:** package.json has no npm lifecycle scripts., The documented helper exports are otherwise simple local utilities. ## Public findings ### 1.
