MAL-2026-12292

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

Details: Source: amazon-inspector (fcfe9505e3a40e8cd4c314f982901e6cbc0c988fbe6ae5fef58c6c1dc5b78a33) [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.

All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
