Malicious code in statist-browser-typed-client-mb.product.analytics (npm)

On require() of the package, index.js loads _bridge.js which detects the host platform, fetches a native binary from a rotating list of hardcoded Cloudflare workers.dev endpoints (with a DNS-TXT chunked base64 fallback via well1.site subdomains), writes it to /tmp or %TEMP% under a masquerading name such as dotnet_diag_<hex>.exe or.cache_<hex>, chmods 0755, and spawns it detached via cmd.exe or /bin/sh. The C2 hostnames and payload paths are assembled at runtime through array-join string-splitting to evade static analysis, and the require of _bridge.js is wrapped in a try/catch that silently swallows errors. No hash or signature verification is performed on the downloaded binary. The result is full-host remote code execution on any machine that installs or requires this package.
