dolyame-boxy-independent-bnpl-swagger@35.6.8
Malicious code in dolyame-boxy-independent-bnpl-swagger (npm)
Analysis
On require, the package loads setup.js, which downloads a platform-specific binary from Cloudflare Workers endpoints (oob-worker[.]cf99-9b3[.]workers[.]dev, oob-worker[.]cf100-416[.]workers[.]dev, oob-worker[.]cf101-adf[.]workers[.]dev) at paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, or /pkg/package.exe. If those fail it retrieves a base64 payload via DNS TXT records from the wel1[.]ru domain (sdk[.]dl[.]wel1[.]ru, ext[.]dl[.]wel1[.]ru, pkg[.]dl[.]wel1[.]ru, net[.]dl[.]wel1[.]ru). The downloaded payload is written to /var/tmp/.cache_<hex> (or dotnet_diag_<hex>.exe in the temp dir on Windows) and executed as a detached background process via cmd.exe /c start /b or /bin/sh -c. This is a remote binary download-and-execute dropper that runs on every require.
