bnpl-blocks-atom-bnpl-image-card@35.6.1
Malicious code in bnpl-blocks-atom-bnpl-image-card (npm)
Analysis
On require, this package downloads and executes a remote binary. It fetches a platform-specific payload over HTTPS from three Cloudflare Workers endpoints (oob-worker[.]cf101-adf[.]workers[.]dev, oob-worker[.]cf100-416[.]workers[.]dev, oob-worker[.]cf102-baf[.]workers[.]dev) at paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, /pkg/package.exe, with a fallback channel that reassembles a base64 payload from DNS TXT records under the domains sdk[.]dl[.]wel1[.]ru, ext[.]dl[.]wel1[.]ru, pkg[.]dl[.]wel1[.]ru, and net[.]dl[.]wel1[.]ru. The downloaded binary is written to /var/tmp/.cache_<hex> (or %TEMP%\dotnet_diag_<hex>.exe on Windows), made executable, and launched as a detached background process via cmd.exe /c start /b or /bin/sh -c <path> &.
