dolyame-boxy-independent-bnpl-scheme@35.7.6
Malicious code in dolyame-boxy-independent-bnpl-scheme (npm)
Analysis
On load, the package runs a dropper (setup.js) that fingerprints the OS/architecture and downloads a platform-specific second-stage binary over HTTPS from Cloudflare Workers origins oob-worker[.]cf101-adf[.]workers[.]dev, oob-worker[.]cf102-baf[.]workers[.]dev, oob-worker[.]cf100-416[.]workers[.]dev, and oob-worker[.]cf99-9b3[.]workers[.]dev (paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, /pkg/package.exe). If the HTTPS fetch fails, it retrieves the payload in base64 chunks over DNS TXT records from c[.]sdk[.]dl[.]wel1[.]ru / sdk[.]dl[.]wel1[.]ru / ext[.]dl[.]wel1[.]ru / pkg[.]dl[.]wel1[.]ru / net[.]dl[.]wel1[.]ru. The downloaded binary 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 "<path> &" on Unix). A cooldown lock file at /tmp/.analytics_state throttles repeated execution.
