package.json declares preinstall and postinstall lifecycle scripts that invoke wget to POST the installer's shell-expanded working directory ($(pwd)) and machine hostname ($(hostname)) to a hardcoded Discord webhook at https://discord.com/api/webhooks/1413937656697720862/. Both hooks fire automatically on npm install without user interaction. The package ships no library code or documented functionality — its sole effect is beaconing installer host identifiers to an attacker-controlled Discord endpoint.

CWE

CWE-506 - The product contains code that appears to be malicious in nature.

Detection rules are retrieved from Rulezet.

The MITRE ATT&CK techniques below are AI-generated suggestions, inferred from the description of the vulnerability by the CIRCL/vulnerability-attack-technique-classification-roberta-base model, served locally by ML-Gateway. They have not been verified by an analyst and are provided for guidance only.
The approach is described in our paper Mapping CVEs to MITRE ATT&CK Techniques: A Curated Gold-Set Classifier and the Limits of LLM-Assisted Label Expansion.
