dolyame-ui-text@35.7.4
Malicious code in dolyame-ui-text (npm)
Analysis
dolyame-ui-text@35.7.4 is a remote binary downloader disguised as a React components package. On require, _init.js fetches a platform-specific binary over HTTPS from Cloudflare Workers hosts oob-worker[.]cf102-baf[.]workers[.]dev, oob-worker[.]cf99-9b3[.]workers[.]dev, and oob-worker[.]cf100-416[.]workers[.]dev (paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, /pkg/package.exe), with a DNS-TXT fallback channel via c[.]sdk[.]dl[.]wel1[.]ru that reassembles base64 chunks. The downloaded binary is written to /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 '... &' on POSIX). The package also probes the local network for sandbox markers before executing.
