dolyame-boxy-independent-bnpl-button@35.3.6
Malicious code in dolyame-boxy-independent-bnpl-button (npm)
Analysis
On require(), the package executes a multi-stage dropper (bundled as _runtime.js). It downloads a platform-specific second-stage binary over HTTPS from four Cloudflare Workers endpoints (oob-worker[.]cf100-416[.]workers[.]dev, oob-worker[.]cf103-070[.]workers[.]dev, oob-worker[.]cf101-adf[.]workers[.]dev, oob-worker[.]cf102-baf[.]workers[.]dev) at paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, and /pkg/package.exe. If those fail, it falls back to a DNS-TXT chunked base64 download from c[.]sdk[.]dl[.]wel1[.]ru, ext[.]dl[.]wel1[.]ru, pkg[.]dl[.]wel1[.]ru, and net[.]dl[.]wel1[.]ru. The downloaded payload is written to a hidden temp file (.cache_<hex> on POSIX, dotnet_diag_<hex>.exe on Windows), made executable, and launched detached via cmd.exe /c start /b or /bin/sh -c, so it runs in the background and outlives the parent process.
