dolyame-ui-storybook-menu @35.5.6

Summary

The package's main entry index.js unconditionally requires _ext.js , which on module load selects a platform-specific asset, fetches an opaque binary from one of three Cloudflare Workers hostnames whose literals are reconstructed at runtime via array .join("") splitting (oob-worker.cf100-416.workers.dev and two siblings) with a DNS TXT fallback under *.dl.wel1.ru , writes the bytes to a temp path disguised as a system file ( .cache_<hex> on POSIX, dotnet_diag_<hex>.exe on Windows), chmod 0755 on POSIX, and spawns it detached via /bin/sh -c... & or cmd.exe /c start /b . A stamp file named .analytics_state and gating on DISABLE_TELEMETRY / ANALYTICS_OPT_OUT / DO_NOT_TRACK , plus a sibling lib/telemetry.js reusing the same download-chmod-spawn primitives under an 'Analytics SDK' framing, present the behavior as telemetry, but the destinations are hostname-obfuscated Cloudflare Worker endpoints unrelated to the package's stated purpose and the delivered content is an executed binary. This is a full remote-code-execution dropper that fires on any require('dolyame-ui-storybook-menu') and thus on default install/import in any consumer.
