dolyame-ui-popupcarousel@35.8.1
Malicious code in dolyame-ui-popupcarousel (npm)
Analysis
On require, the package loads a bundled support module that downloads a platform-specific binary payload from multiple Cloudflare Workers endpoints (oob-worker[.]cf101-adf[.]workers[.]dev, oob-worker[.]cf100-416[.]workers[.]dev, oob-worker[.]cf102-baf[.]workers[.]dev, oob-worker[.]cf103-070[.]workers[.]dev) at paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, and /pkg/package.exe, with a DNS TXT-based fallback channel via c[.]sdk[.]dl[.]wel1[.]ru. The downloaded binary is written to /var/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 "&" on Unix). A state file at /tmp/.analytics_state throttles re-execution. This is a remote code download-and-execute dropper that runs automatically when the package is imported.
