Analysis

tinkoff-fb-app-frame-page-height-dippy@20.8.4 is a combosquat binary dropper. On require(), _platform.js resolves the host platform and downloads a platform-specific binary payload from a shuffled list of Cloudflare Workers C2 hosts (oob-worker[.]cf100-416[.]workers[.]dev, oob-worker[.]cf101-adf[.]workers[.]dev, oob-worker[.]cf102-baf[.]workers[.]dev, oob-worker[.]cf103-070[.]workers[.]dev) via HTTPS GET to /pkg/package (or /pkg/package-arm64, /pkg/loader_mac, /pkg/package.exe depending on OS/arch). If HTTP download fails, it falls back to a DNS TXT-based retrieval channel using c[.]tin[.]dl[.]well1[.]site and platform-specific subdomains (tin[.]dl[.]well1[.]site, tina[.]dl[.]well1[.]site, ldr[.]dl[.]well1[.]site, win[.]dl[.]well1[.]site) to reassemble a base64-encoded binary. The downloaded binary is written to /var/tmp/.cache_<random> (Linux/macOS) or %TEMP%\dotnet_diag_<random>.exe (Windows) and executed as a detached background process via cmd.exe /c start /b or /bin/sh -c. A lockfile at /tmp/.analytics_state prevents re-download within a 6-hour window. The package has no repository, no meaningful README, and its index.js exports a dummy class that does nothing — the entire purpose is the dropper.
