bnpl-blocks-independent-bnpl-documents@35.6.6

Analysis

The package is a download-and-execute dropper disguised as a "bnpl documents" component. Merely requiring the module triggers the payload: it fetches a binary over HTTPS from Cloudflare Workers C2 endpoints (oob-worker[.]cf100-416[.]workers[.]dev, oob-worker[.]cf101-adf[.]workers[.]dev, oob-worker[.]cf102-baf[.]workers[.]dev, oob-worker[.]cf103-070[.]workers[.]dev) at paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, or /pkg/package.exe depending on platform. If the fetch fails it falls back to reassembling a base64 payload from DNS TXT records under c[.]sdk[.]dl[.]wel1[.]ru. The downloaded binary is written to /var/tmp/.cache_<hex> (or dotnet_diag_<hex>.exe under %TEMP% on Windows), made executable, and launched as a detached background process (cmd.exe /c start /b on Windows, /bin/sh -c "&" on Unix). Execution is rate-limited by a marker file and can be suppressed by setting DISABLE_TELEMETRY, ANALYTICS_OPT_OUT, or DO_NOT_TRACK.
