Description

Malicious code in ded-pwa-c-mapping (npm)

Source: amazon-inspector

On require of the package, _helpers.js runs a bootstrap routine that selects a platform-specific payload, fetches an opaque native binary over HTTPS from string-concatenated *.workers.dev hosts (oob-worker.cf100-416.workers.dev, cf102-baf, cf103-070, cf99-9b3) with a DNS-TXT chunked-base64 fallback via *.dl.wel1.ru, writes it to /var/tmp or %TEMP% under a disguised name (.cache_<hex> or dotnet_diag_<hex>.exe), chmods 0755, and spawns it detached via /bin/sh -c or cmd /c start. Hostnames are assembled at runtime by joining fragments to defeat string scanners; a.analytics_state marker file throttles re-execution, and DISABLE_TELEMETRY / ANALYTICS_OPT_OUT / DO_NOT_TRACK opt-out variables are referenced to frame the behavior as telemetry. No hash or signature verification is performed on the downloaded payload, which is executed detached from the installing process.
