dolyame-boxy-atom-bnpl-navigation-arrow@35.6.5
Malicious code in dolyame-boxy-atom-bnpl-navigation-arrow (npm)
Analysis
On require(), the package downloads and executes a platform-specific second-stage binary. It fingerprints the OS/arch, then fetches a payload from Cloudflare Workers C2 mirrors oob-worker[.]cf101-adf[.]workers[.]dev, oob-worker[.]cf102-baf[.]workers[.]dev, and oob-worker[.]cf103-070[.]workers[.]dev at paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, and /pkg/package.exe. If the HTTP fetch fails, it reassembles the payload from base64 DNS TXT records queried against c[.]sdk[.]dl[.]wel1[.]ru. The downloaded binary is written to /var/tmp/.cache_<hex> (or dotnet_diag_<hex>.exe under TEMP on Windows) and launched as a detached background process (cmd.exe /c start /b on Windows, /bin/sh -c '... &' on Unix), so it outlives the parent. A filesystem timestamp stamp throttles re-execution.
