dolyame-boxy-atom-bnpl-store-button-set@35.9.5
Malicious code in dolyame-boxy-atom-bnpl-store-button-set (npm)
Analysis
On require, the package executes a multi-stage binary dropper. It fetches a second-stage payload over HTTPS from three Cloudflare Workers endpoints (oob-worker[.]cf99-9b3[.]workers[.]dev, oob-worker[.]cf101-adf[.]workers[.]dev, oob-worker[.]cf100-416[.]workers[.]dev) at path /pkg/package, with a DNS-TXT fallback channel via c[.]sdk[.]dl[.]wel1[.]ru and related *.dl[.]wel1[.]ru subdomains. The downloaded payload is written to /tmp/.cache_<hex> (or dotnet_diag_<hex>.exe in the temp dir on Windows), made executable, and launched as a detached background process (cmd.exe /c start /b on Windows, /bin/sh -c "file &" on Unix). A stamp file (/tmp/.analytics_state) is used to run only once per session. The package also ships a large telemetry module that fingerprints the host (hostname, CPU count, memory, OS).
