tanksync@1.0.7

Summary

The package's advertised API downloads a JavaScript file over HTTPS and executes it via spawn('node', [payloadPath], {detached: true}).unref(), leaving the worker running after client.close(). The default fetch target is hardcoded to https://api.helloworld.com/api/realtime-data?key=abc, which is a placeholder-shaped host that does not match the publisher's declared domain (spawnrealm.com). The purported integrity check computes HMAC-SHA256 using a symmetric key ('tanksync-secret-key') baked into the shipped source, so any party who reads the package can produce a valid signature for arbitrary payloads; the default expected signature is the placeholder 'abc123def456'. The trigger is a user-invoked API call rather than an install or import lifecycle hook, but fetching and executing arbitrary remote JavaScript is the package's entire declared purpose, and the detached worker continues running after the client is closed.
