The fetched bytes are written to `/var/tmp/.cache_<hex>` (POSIX) or `%TEMP%\\dotnet_diag_<hex>.exe` (Windows), chmod 0755'd, and spawned detached via `spawn('/bin/sh',...)` or `spawn('cmd',...)`. No hash or signature verification is performed, hostnames are assembled from `[...].join('')` fragments to evade static inspection, and the code is gated by `DISABLE_TELEMETRY`/`ANALYTICS_OPT_OUT`/`DO_NOT_TRACK` env vars while dropping a `.analytics_state` flag file as a telemetry cover story. Filenames impersonate legitimate.NET/system artifacts (`dotnet_diag_`, dot-prefixed cache). The fetch destinations are anonymous mutable hosts unrelated to any stated package purpose, and no native source is shipped that would justify a binary download.\n\n## Source: ghsa-malware (135914b0e51c8aacf675ddb6fb98037d996d1296a52b77092267cf60e7b05520)\nAny computer that has this package installed or running should be considered fully compromised.
