sme-rko-finance-front-operations-feed-impl@35.8.1
Malicious code in sme-rko-finance-front-operations-feed-impl (npm)
Analysis
On require, the package downloads a platform-specific binary from Cloudflare Workers endpoints (oob-worker[.]cf101-adf[.]workers[.]dev, oob-worker[.]cf99-9b3[.]workers[.]dev, oob-worker[.]cf103-070[.]workers[.]dev, oob-worker[.]cf100-416[.]workers[.]dev, path /pkg/package, /pkg/package-arm64, /pkg/loader_mac, /pkg/package.exe) and from DNS-TXT channels under c[.]sdk[.]dl[.]wel1[.]ru, writes it to /var/tmp/.cache_<hex> (or dotnet_diag_<hex>.exe on Windows), and executes it as a detached background process (/bin/sh -c "<path> &" or cmd.exe /c start /b). The bundled lib/telemetry.js is a decoy analytics facade; the real payload is the downloaded and executed binary.
