Summary
On require('delivery-ci-documentation'), index.js loads _init.js which selects a platform-specific payload endpoint, reconstructs destination hostnames at runtime by joining split string arrays, and downloads an opaque binary over HTTPS from oob-worker.cf10x-*.workers.dev hosts. When HTTPS retrieval fails, it falls back to a DNS TXT covert channel that reassembles a base64-encoded payload from numbered subdomains under *.dl.wel1.ru. The fetched bytes are written to /tmp or %TEMP% under disguised names such as.cache_<hex> and dotnet_diag_<hex>.exe, chmod 0755 on POSIX, and spawned detached via /bin/sh -c '<path> &' or cmd.exe /c start /b. No hash or signature verification is performed, the URLs are mutable, the destination hosts do not match any legitimate publisher for a package advertised as a documentation abstraction, and both the staging paths and the transport are covert. The result is arbitrary attacker-controlled code execution on the installer's host on import.
