Malicious code in devplatform-api-clients (npm)
--- _-= Per source details.

The endpoints are concealed by splitting the hostnames into string arrays that are joined at runtime. The downloaded binary is written to /tmp or %TEMP% under stealth names such as dotnet_diag_<rand>.exe or.cache_<rand> (setup.js line ~119), chmod 0755'd, and spawned detached via spawn('/bin/sh', ['-c', fp+' &']).unref() or the cmd equivalent. A marker file gates re-execution and DISABLE_TELEMETRY / DO_NOT_TRACK env vars are honored as a plausible-deniability cover. The package advertises itself as a service-client SDK; a client SDK has no need to fetch and execute an opaque native binary from a third-party edge host at require time.
