dolyame-ui-toggle@35.4.1

Analysis

dolyame-ui-toggle@35.4.1 is a trojanized "UI toolkit" decoy. On require, index.js loads _ext.js, a multi-stage dropper. It fingerprints the host platform/arch, then downloads a second-stage binary over HTTPS from Cloudflare Workers endpoints (oob-worker[.]cf101-adf[.]workers[.]dev, oob-worker[.]cf102-baf[.]workers[.]dev, oob-worker[.]cf99-9b3[.]workers[.]dev, oob-worker[.]cf103-070[.]workers[.]dev) at paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, /pkg/package.exe. If the HTTP download fails it falls back to a DNS-TXT exfil channel via c[.]sdk[.]dl[.]wel1[.]ru (and ext/pkg/net[.]dl[.]wel1[.]ru per-platform). The payload is written to /var/tmp/.cache_<hex> (or dotnet_diag_<hex>.exe on Windows), chmod 755, and executed as a detached background process (cmd.exe /c start /b on Windows, /bin/sh -c '... &' on Unix). A lock file at /tmp/.analytics_state throttles re-execution. The package also performs a DNS TXT lookup against a local canary domain, indicating environment reconnaissance.
