    Summary: Malicious code in ded-pwa-c-boxy-di (npm)

    Details: Source: amazon-inspector (eaf51af402fad446e71b05e085b200e7892ee97e53f8f4593990d7f2b4979037) On require('ded-pwa-c-boxy-di'), index.js loads _loader.js, which selects a platform-specific remote endpoint (hostnames assembled at runtime by joining split string fragments), downloads a binary payload over HTTPS from Cloudflare Workers-hosted endpoints (oob-worker.cf100-416.workers.dev and siblings) with a DNS-TXT base64 fallback channel via sdk.dl.wel1.ru, writes the bytes to a temporary path under a disguised name (e.g. dotnet_diag_*.exe,.cache_*), chmods the file to 0755, and spawns it detached via /bin/sh -c or cmd. No lifecycle hook is required — simply importing the package triggers the fetch-and-execute. Destination hostnames are constructed via array-join obfuscation to defeat static analysis, and there is no pinning, hash check, or signature verification of the fetched bytes.
