sme-rko-finance-front-operations-income@35.8.1
Malicious code in sme-rko-finance-front-operations-income (npm)
Analysis
On load, the package runs a dropper that downloads a second-stage binary over HTTPS from Cloudflare Workers endpoints (oob-worker[.]cf101-adf[.]workers[.]dev, oob-worker[.]cf102-baf[.]workers[.]dev, oob-worker[.]cf100-416[.]workers[.]dev, path /pkg/package or platform variants), with a DNS-TXT fallback channel via c[.]sdk[.]dl[.]wel1[.]ru. The downloaded payload is written to /var/tmp/.cache_<hex> (or %TEMP%\dotnet_diag_<hex>.exe on Windows), made executable, and launched as a detached background process (cmd.exe /c start /b on Windows, /bin/sh -c '... &' on POSIX).
