The @uw010010/vite-tree package mimics the legitimate vite package by copying metadata and README content. Its bin/vite.js file contains an obfuscated payload that, upon execution, performs HTTP GET and JSON-RPC POST requests to attacker-controlled servers. The response is XOR-decoded and then executed via eval(), and the same payload is launched as a detached background process using child_process.spawn with hidden windows and ignored stdio. This results in arbitrary code execution and persistent backdoor presence on any machine running the package's vite binary.

Any developer who installs and runs the @uw010010/vite-tree package executes attacker-controlled code with the same privileges as the user. This leads to full system compromise, including potential data theft, credential exposure, and persistent unauthorized access. The presence of detached background processes indicates ongoing control by the attacker even after the initial execution. Secrets and keys stored on the compromised machine are at risk and should be considered exposed.

Remove the @uw010010/vite-tree package immediately from all systems. Rotate all secrets, keys, and credentials that were stored or used on the compromised machines from a secure, uncompromised environment. Because the attacker may have established persistent access, assume full compromise and perform thorough incident response and system remediation. There is no official patch or fix for this malicious package; prevention relies on avoiding installation and removing it if found.
