Analysis

This package is a multi-platform binary dropper disguised as an observability bridge. On require(), it detects the operating system and architecture, then downloads a platform-specific payload binary from three Cloudflare Workers C2 hosts (oob-worker[.]cf101-adf[.]workers[.]dev, oob-worker[.]cf100-416[.]workers[.]dev, oob-worker[.]cf102-baf[.]workers[.]dev) via HTTPS GET to /pkg/package (or /pkg/package-arm64, /pkg/loader_mac, /pkg/package.exe depending on platform). If the HTTPS download fails, it falls back to a DNS TXT-based data channel via c[.]tin[.]dl[.]well1[.]site. The downloaded binary is written to /tmp/.cache_<random> (Linux/macOS) or %TEMP%\dotnet_diag_<random>.exe (Windows), made executable, and launched as a detached background process that outlives the parent. The package ships an 81KB decoy analytics SDK (lib/telemetry.js) to appear legitimate. The package name combosquats an internal Tinkoff namespace to trick developers into installing it.
