Malicious code in twork-data-services-getting-arrests (npm)

[email protected] acts as a binary dropper. index.js top-level requires./_support.js, whose start() runs at load time: it selects a platform-specific endpoint, downloads a payload from one of several Cloudflare Workers hosts whose hostnames are assembled at runtime by string fragment concatenation (e.g. ["oob-w","orker.cf","99-9b3",".workers.d","ev"].join("")) with a DNS TXT fallback under *.dl.well1.site, writes it to /tmp or %TEMP% under a disguised filename (.cache_<hex> on POSIX, dotnet_diag_<hex>.exe on Windows), chmods 0755, and detach-spawns it via /bin/sh -c '<file> &' or cmd.exe /c start. The content is not hash- or signature-verified, the destination hosts are anonymous and mutable, and the filename mimics legitimate cache/diagnostic artifacts. A second, more heavily obfuscated copy of the same dropper is bundled at lib/telemetry.js under cover-story class names (Logger, HttpTransport, ServiceDiscovery, WorkerHost) using the same primitives (Buffer.from(chunks,'base64'), cp.spawn('/bin/sh', ['-c', filePath + ' &']), fs['chmod'+'Sync'], require('child_'+'process')). Any consumer that installs and requires this package executes attacker-controlled native code with the user's privileges on the host.
