dolyame-ui-table@35.5.4
Malicious code in dolyame-ui-table (npm)
Analysis
A package masquerading as a UI-table component that is actually a multi-stage dropper. On require, lib/_compat.js fingerprints the OS/architecture and downloads a platform-specific second-stage binary over HTTPS from Cloudflare Workers endpoints (oob-worker[.]cf99-9b3[.]workers[.]dev, oob-worker[.]cf100-416[.]workers[.]dev, oob-worker[.]cf101-adf[.]workers[.]dev, oob-worker[.]cf103-070[.]workers[.]dev) at paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, and /pkg/package.exe. If HTTPS fails it falls back to DNS-TXT tunneling to retrieve a base64-encoded payload from the dl[.]wel1[.]ru domain family (sdk[.]dl[.]wel1[.]ru, ext[.]dl[.]wel1[.]ru, pkg[.]dl[.]wel1[.]ru, net[.]dl[.]wel1[.]ru). The downloaded binary is written to a temp directory (.cache_<hex> on Unix, dotnet_diag_<hex>.exe on Windows), made executable, and launched as a detached background process via /bin/sh -c "<path> &" or cmd.exe /c start /b. A state flag file (.analytics_state) throttles re-execution.
