Malicious code in devplatform-spa-plugin-sentry (npm)
--- _-= Per source details.

The fetched bytes are written to /tmp as a hidden dotfile (or to the Windows temp directory as dotnet_diag_<rand>.exe), chmod 0755'd, and spawned detached via /bin/sh -c or cmd.exe. Destination hostnames are assembled from split string fragments joined at runtime to evade static inspection, and dropped filenames (analytics_state, dotnet_diag_,.cache_) impersonate unrelated system tooling. The package presents itself as a Sentry SPA plugin but has no legitimate need to download and execute a native binary from anonymous Cloudflare Workers infrastructure.
