It executes the downloaded platform-specific binary detached in the background. - **Trigger:** Runtime require/import of index.js. - **Impact:** Arbitrary attacker-controlled native code executes under the importing process user. - **Evidence paths:** package.json, index.js, \_adapter.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T13:35:12.724Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** remote binary download via HTTPS/DNS followed by detached execution - **Attack narrative:** A normal require of index.js silently imports \_adapter.js, which immediately runs setup(). It contacts obfuscated workers.dev mirrors for a platform payload, with DNS TXT chunk reconstruction as fallback, stores the result in a temporary directory, marks it executable, and launches it detached through a shell or cmd.exe. The package’s claimed markdown API is minimal and unrelated to this behavior. - **Rationale:** This is concrete import-time staged payload delivery and execution, not legitimate package-aligned telemetry. Lack of an npm lifecycle hook does not mitigate runtime compromise of consumers. - **Files touched:** index.js, \_adapter.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, C:\\Windows\\Temp\\analytics\_state, C:\\Windows\\Temp\\dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf100-416.workers.dev, oob-worker.cf103-070.workers.dev, oob-worker.cf102-baf.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 \_adapter.js on every package require., \_adapter.js fetches platform binaries from hidden workers.dev hosts., DNS TXT fallback reconstructs a binary from dl.wel1.ru domains., Downloaded bytes are written to /var/tmp or Windows Temp, chmodded, then detached-spawned., The marker only rate-limits execution and uses misleading analytics filenames. - **Evidence against:** package.json has no npm lifecycle scripts., No credential harvesting or outbound data exfiltration was found in the reachable adapter. ## Public findings ### 1.
