Background
The yanti-pecel81-ruro package is part of the npm ecosystem, which is widely used for JavaScript package management. This package is associated with the tea.xyz token reward campaign, which has been known to flood the npm registry with malicious packages. The primary functionality of this package is to serve as a token reward mechanism, but it has been compromised to include harmful scripts that manipulate package metadata.
