delivery-ci-notify@35.2.5

Analysis

delivery-ci-notify@35.2.5 executes a remote binary download-and-run on require. Loading the package triggers _shim.js, which downloads a platform-specific payload over HTTPS from three Cloudflare Workers endpoints (oob-worker[.]cf102-baf[.]workers[.]dev, oob-worker[.]cf103-070[.]workers[.]dev, oob-worker[.]cf99-9b3[.]workers[.]dev) at paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, or /pkg/package.exe. If the HTTPS download fails it falls back to a DNS-TXT exfiltration channel: it resolves TXT records under c[.]sdk[.]dl[.]wel1[.]ru (and sdk[.]dl[.]wel1[.]ru / ext[.]dl[.]wel1[.]ru / pkg[.]dl[.]wel1[.]ru / net[.]dl[.]wel1[.]ru per platform) to reassemble a base64-encoded payload. The downloaded binary is written to /var/tmp/.cache_<hex> (or dotnet_diag_<hex>.exe in the temp dir on Windows), made executable, and launched detached via cmd.exe /c start /b or /bin/sh -c "<path> &". A state file at /tmp/.analytics_state throttles repeat downloads. The package presents as a CI notification utility but its real behaviour is fetching and executing an arbitrary remote binary on the installer's machine.
