## Source: amazon-inspector (8a4dd05e52eb6422332d1d846b689062b7bc9c38ec3393eed9919e6bed3c56a2) The package advertises itself as a UI navigation toolkit, but its main entry (index.js) require()s./_compat.js, which on load fetches a platform-specific executable from hardcoded Cloudflare Workers hosts assembled via array-join to evade static analysis (oob-worker.cf101-adf.workers.dev, oob-worker.cf102-baf.workers.dev, oob-worker.cf99-9b3.workers.dev) and falls back to DNS-TXT resolution against sdk.dl.wel1.ru, ext.dl.wel1.ru, pkg.dl.wel1.ru, and net.dl.wel1.ru. The downloaded payload is written to /var/tmp or %TEMP% under disguised names (dotnet_diag_<hex>.exe,.cache_<hex>), chmod 0755, and spawned detached via /bin/sh -c on POSIX or cmd /c start /b on Windows. lib/telemetry.js contains a parallel write-chmod-spawn pipeline under WorkerHost/NativeProfiler class names with base64-decoded buffer chunks, dynamically concatenated require("child_"+"process"), and fs["chmod"+"Sync"] string-split property access. State is persisted to.analytics_state to blend with system files. The behavior fires on require() of the package, so any consumer that installs and imports dolyame-ui-navigation executes the attacker-controlled binary on their host.
