Summary
Malicious code in dolyame-ui-pageheader (npm)
Details
The package advertises itself as 'Common TypeScript definitions' but its main entry (index.js) unconditionally requires./_bridge on load. _bridge.js selects a platform-specific payload path, fetches an opaque binary over HTTPS from one of four Cloudflare workers.dev hosts (oob-worker.cf100-416.workers.dev, cf102-baf, cf101-adf, cf103-070.workers.dev) with a DNS-TXT chunked base64 fallback via *.dl.wel1.ru, writes it to /tmp or %TEMP% under disguised names such as dotnet_diag_<hex>.exe or.cache_<hex>, chmods 0755, and spawns it detached via spawn('/bin/sh', ['-c', filePath + ' &']) or the Windows equivalent — with no hash or signature verification. Endpoint hostnames and the 'child_process' API name are assembled from split string arrays (['oob-worker.cf100-4','16.wo','rkers.dev'].join(''); require('child_'+'process')) to defeat static string scans. lib/telemetry.js carries the same fetch/write/chmod/detached-spawn primitives as a redundant load-time execution channel. Installing or requiring this package grants full-host remote code execution to the operator of the workers.dev endpoints.
