    Summary: Malicious code in cards-forms-clone-cards-core-clone (npm)

    Details: Source: amazon-inspector (74486d1afedd40c87c6d604f98ffda15100b2ee63af56e8f7330346d915269c9) On require(), index.js loads _platform.js, which selects a platform-specific asset URL from obfuscated hostnames assembled via split-then-join string fragments (oob-worker.cf102-baf.workers.dev, cf103-070, cf99-9b3, cf100-416 workers.dev hosts, plus a DNS-TXT chunked fallback to *.dl.wel1.ru), downloads the payload, writes it to a hidden temp file, chmods it 0755 (or names it dotnet_diag_*.exe on Windows), and spawns it detached via /bin/sh -c or cmd.exe /c start /b. A stamp file named.analytics_state and env gates DISABLE_TELEMETRY/ANALYTICS_OPT_OUT/DO_NOT_TRACK provide a telemetry cover story; the package's advertised purpose is a base framework module unrelated to any such behavior. String-fragment obfuscation of the destination hosts and the masquerading filenames are deliberate evasion.
