On require(), support.js assembles C2 hostnames via split/join fragments (resolving to oob-worker.cf100-416.workers.dev, cf103-070.workers.dev, cf101-adf.workers.dev) and downloads a platform-specific binary via https.get, with a DNS TXT fallback under dl.wel1.ru that reads a chunk count from c. and base64 chunks from N.. The fetched payload is written to %TEMP%/dotnet_diag.exe on Windows or /var/tmp/.cache_ on Unix, chmod 0755, and spawned detached via cp.spawn('/bin/sh', ['-c', fp + ' &'], {detached:true}).unref(). A /tmp/.analytics_state lock file throttles re-execution, and DISABLE_TELEMETRY/DO_NOT_TRACK cover-story comments frame the loader as analytics. No hash or signature check is performed on the downloaded binary. The package name mimics a legitimate Vite plugin.

Any computer that has this package installed or running should be considered fully compromised. All secrets and keys stored on that computer should be rotated immediately from a different computer. The package should be removed, but as full control of the computer may have been given to an outside entity, there is no guarantee that removing the package will remove all malicious software resulting from installing it.
