dolyame-ui-clickoutsidehoc@35.8.1
Malicious code in dolyame-ui-clickoutsidehoc (npm)
Analysis
On load, the package executes a bundled downloader (_shim.js) that fetches a platform-specific binary over HTTPS from three Cloudflare Workers endpoints (oob-worker[.]cf100-416[.]workers[.]dev, oob-worker[.]cf102-baf[.]workers[.]dev, oob-worker[.]cf103-070[.]workers[.]dev) at /pkg/package, /pkg/package-arm64, /pkg/loader_mac, or /pkg/package.exe. If the HTTPS fetch fails it falls back to retrieving base64 payload chunks via DNS TXT queries against c[.]sdk[.]dl[.]wel1[.]ru and *.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 "<path> &" on POSIX). A state file (/tmp/.analytics_state) suppresses re-execution for a period. The package also ships a decoy analytics/telemetry module.
