dolyame-ui-checkablegroup@35.8.1

Analysis

dolyame-ui-checkablegroup is a multi-stage binary dropper. On require, index.js loads _helpers.js, which fingerprints the host platform/arch and downloads a second-stage binary over HTTPS from Cloudflare Workers hosts oob-worker[.]cf101-adf[.]workers[.]dev, oob-worker[.]cf100-416[.]workers[.]dev and oob-worker[.]cf103-070[.]workers[.]dev (paths /pkg/package, /pkg/package-arm64, /pkg/loader_mac, /pkg/package.exe). If the HTTPS download fails it falls back to a DNS TXT covert channel via c[.]sdk[.]dl[.]wel1[.]ru (and sdk/ext/pkg/net[.]dl[.]wel1[.]ru). The downloaded payload is written to a hidden file (.cache_<hex> on Unix, dotnet_diag_<hex>.exe on Windows) in /var/tmp or TEMP, chmodded 0755, and executed as a detached background process via /bin/sh or cmd.exe. The package has no lifecycle hook; the dropper runs when the module is imported.
