It downloads or DNS-reconstructs a platform binary, writes it to a temporary directory, and executes it detached. - **Trigger:** Any runtime require/import of the package entrypoint - **Impact:** Arbitrary native code execution under the importing process user. - **Evidence paths:** package.json, index.js, \_support.js, lib/telemetry.js - **Review source:** ai\_review - **Reviewed:** 2026-08-05T15:11:33.578Z ### AI review details - **Review stage:** source\_first\_review - **Mechanism:** Remote binary download/DNS staging followed by detached execution - **Attack narrative:** The declared entrypoint suppresses errors while importing \_support.js. That module runs setup() immediately, contacts obfuscated Cloudflare Worker hosts for an OS-specific binary and falls back to DNS TXT payload retrieval. It writes the received bytes to a concealed temporary filename, chmods it on Unix, and launches it detached via shell or cmd.exe. This is an unconsented runtime remote-code execution chain. - **Rationale:** The package’s minimal documented API has no legitimate need to fetch and execute an opaque native payload on import. The concrete loader behavior establishes malicious remote execution despite the absence of lifecycle hooks. - **Files touched:** index.js, \_support.js, /tmp/.analytics\_state, /var/tmp/.cache\_\, %TEMP%/analytics\_state, %TEMP%/dotnet\_diag\_\.exe - **Network endpoints:** oob-worker.cf99-9b3.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf100-416.workers.dev, oob-worker.cf101-adf.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 \_support.js at module load., \_support.js downloads platform binaries from obfuscated worker hosts., DNS TXT fallback reconstructs a base64 payload from \*.dl.wel1.ru., Downloaded data is written to /var/tmp or Windows Temp, made executable, then spawned detached. - **Evidence against:** package.json has no lifecycle scripts., lib/telemetry.js is not imported by the declared entrypoint. ## Public findings ### 1.
