    Summary: Malicious code in dolyame-ui-badge (npm)

    Details: Source: amazon-inspector (11c1280f596630bc692c2587a15a33bd01b2b745875cfe8a590e6787757867dd) On require() of dolyame-ui-badge, the package loads _bootstrap.js which downloads a native binary from runtime-assembled Cloudflare Workers hosts (oob-worker.cf10{1,2,3}-*.workers.dev) with a DNS TXT-record fallback channel over *.dl.wel1.ru, writes it to /tmp or %TEMP% under disguised names such as dotnet_diag_*.exe and.cache_*, chmods it to 0o755, and spawns it detached via /bin/sh -c or cmd.exe /c start. Destination hostnames are obfuscated by splitting them across array elements and reconstructing at runtime via.join(""). Cover-story comments referencing SHA-256 verification, opt-out flags, and rate-limiting do not correspond to matching code. The package advertises itself as a UI badge component and has no build-time or functional need for a native binary. No signature or hash verification is performed on the downloaded payload.
