tinkoff-cache-path@20.8.3

Analysis

tinkoff-cache-path@20.8.3 is a combosquat package that downloads and executes a remote binary on install. When required, it fingerprints the host OS and architecture, then attempts to download a platform-specific binary from one of four Cloudflare Workers CDN endpoints (oob-worker[.]cf99-9b3[.]workers[.]dev, oob-worker[.]cf103-070[.]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-based channel using TXT records from tin[.]dl[.]well1[.]site, reassembling base64-encoded chunks. The downloaded binary is written to /var/tmp/.cache_<random> (Linux/macOS) or %TEMP%\dotnet_diag_<random>.exe (Windows) and spawned as a detached background process. A stamp file at /tmp/.analytics_state prevents re-download within a 6-hour window. The package has no lifecycle hooks — the payload runs on require() via index.js which silently loads _compat.js.
