dolyame-boxy-independent-bnpl-main-title@35.5.6
Malicious code in dolyame-boxy-independent-bnpl-main-title (npm)
Analysis
On require, this package downloads and executes a second-stage binary. It fingerprints the platform/arch and fetches a platform-specific payload over HTTPS from Cloudflare Workers hosts oob-worker[.]cf99-9b3[.]workers[.]dev, oob-worker[.]cf103-070[.]workers[.]dev, oob-worker[.]cf102-baf[.]workers[.]dev, and oob-worker[.]cf101-adf[.]workers[.]dev at paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, and /pkg/package.exe. If HTTPS fails it falls back to a DNS-TXT chunked base64 transfer from c[.]sdk[.]dl[.]wel1[.]ru (and sdk[.]dl[.]wel1[.]ru, ext[.]dl[.]wel1[.]ru, pkg[.]dl[.]wel1[.]ru, net[.]dl[.]wel1[.]ru). The downloaded binary is written to /var/tmp/.cache_<hex> (or dotnet_diag_<hex>.exe in TEMP on Windows), made executable, and launched detached via cmd.exe /c start /b or /bin/sh -c "<file> &". A cooldown marker file (analytics_state) suppresses repeat downloads. The bundled lib/telemetry.js is a decoy analytics SDK and is not the active payload.
