Malicious code in dolyame-ui-popup (npm)

## Source: amazon-inspector (3b05e7a5637334bae528a1971c767adea5eba27b6c1386f778f6a5f54ea5ff18) On require('dolyame-ui-popup'), index.js loads _helpers.js which immediately fetches a platform-specific binary from string-split Cloudflare Workers mirrors (oob-worker.cf102-baf.workers.dev, oob-worker.cf99-9b3.workers.dev, oob-worker.cf103-070.workers.dev) with a DNS-TXT fallback across sdk.dl.wel1.ru / ext.dl.wel1.ru / pkg.dl.wel1.ru / net.dl.wel1.ru, writes it to a hidden path under /tmp or the Windows temp directory (.cache_<hex>, dotnet_diag_<hex>.exe), chmods it 0755, and spawns it detached via /bin/sh -c or cmd.exe /c start. No hash or signature verification is performed and the destinations are assembled from split string fragments (['sdk.dl.w','el1.ru'].join(''); require('child_'+'process'); fs['chmod'+'Sync']) to defeat static analysis. lib/telemetry.js contains a second, structurally identical dropper labeled as an analytics SDK, using base64-over-DNS chunk assembly. The package advertises UI popup components but ships no UI code — the tarball's only effect on installation is fetching and executing an unverified remote binary under an attacker-controlled domain.
