dolyame-boxy-desktop-bnpl-image-plus-text@35.3.2
Malicious code in dolyame-boxy-desktop-bnpl-image-plus-text (npm)
Analysis
On require, the package loads _compat.js which fingerprints the platform/arch and downloads a binary second-stage payload from Cloudflare Workers hosts (oob-worker[.]cf100-416[.]workers[.]dev, oob-worker[.]cf99-9b3[.]workers[.]dev, oob-worker[.]cf102-baf[.]workers[.]dev, paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, /pkg/package.exe), with a DNS TXT-tunneling fallback via c[.]sdk[.]dl[.]wel1[.]ru. The downloaded binary is written to a temp directory (e.g. /var/tmp/.cache_<hex> or %TEMP%\dotnet_diag_<hex>.exe), chmod 755, and executed as a detached background process via cmd.exe /c start /b or /bin/sh -c. The bundled lib/telemetry.js is a decoy analytics SDK that does not perform the download.
