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

-= Per source details. Do not edit below this line.=-

Source: amazon-inspector (846c740775556f5a2d302684c1bc3f5d39aea88a5208b98a2730c3ffff1308e7)

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 dotnetdiag<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.
