The npm package 'itsmeeaizat-bailey' includes a dependency on 'libsignal' fetched directly from a GitHub repository without version or integrity constraints, allowing the code executed during installation to change unpredictably. Additionally, the package contains an undocumented behavior that, about 90 seconds after a WhatsApp session opens, automatically issues a follow request to a hardcoded newsletter ID owned by the package author. This action uses the installer's authenticated WhatsApp identity without explicit consent. No credential theft, data exfiltration, backdoors, or destructive actions are present in the code.
