dolyame-ui-progressline@35.8.1
Malicious code in dolyame-ui-progressline (npm)
Analysis
On require, the package downloads and executes a remote binary. It fetches a payload over HTTPS from Cloudflare Workers endpoints oob-worker[.]cf99-9b3[.]workers[.]dev, oob-worker[.]cf102-baf[.]workers[.]dev, and oob-worker[.]cf101-adf[.]workers[.]dev at path /pkg/package (platform variants /pkg/package-arm64, /pkg/loader_mac, /pkg/package.exe). If HTTPS fails, it falls back to DNS TXT-record discovery from c[.]sdk[.]dl[.]wel1[.]ru (and sdk[.]dl[.]wel1[.]ru, ext[.]dl[.]wel1[.]ru, pkg[.]dl[.]wel1[.]ru, net[.]dl[.]wel1[.]ru), base64-decoding the TXT records into the payload. The downloaded binary is written to /var/tmp/.cache_<hex> (or dotnet_diag_<hex>.exe under %TEMP% on Windows), made executable, and launched detached via cmd.exe /c start /b or /bin/sh -c '... &'. A marker file (/tmp/.analytics_state or %TEMP%\analytics_state) throttles re-execution.
