dolyame-boxy-independent-bnpl-features@35.9.5
Malicious code in dolyame-boxy-independent-bnpl-features (npm)
Analysis
On require, the package runs a dropper that downloads a second-stage binary over HTTPS from oob-worker[.]cf100-416[.]workers[.]dev, oob-worker[.]cf99-9b3[.]workers[.]dev and oob-worker[.]cf101-adf[.]workers[.]dev (paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, /pkg/package.exe depending on platform). If HTTPS fails it falls back to a DNS-TXT chunked download from c[.]sdk[.]dl[.]wel1[.]ru (resolvers 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 dotnet_diag_<hex>.exe in the temp dir on Windows), made executable, and launched detached via cmd.exe /c start /b or /bin/sh -c "<path> &".
