Malicious code in cordelia-solis-markdown-xerxes (npm)
What this malware does
This package appears to be part of the tea.xyz token reward campaign that flooded npm. These packages typically contain autopublish scripts (auto.js, autopublish.js, autopublish2.js, autopublish3.js) designed to automatically generate and publish derivative packages with randomized names to inflate developer reputation scores for tea protocol token rewards. The malicious payload modifies package.json to remove private flags, changes version numbers, generates random Indonesian-themed package names (some variants are also in English), and continuously republishes variants to pollute the npm registry.
Malicious versions
Every published version of this package is considered malicious — remove it entirely.

Did it already run?
If cordelia-solis-markdown-xerxes was installed, its post-install payload may already have run. Removing the package does not undo that — check outbound connections and credential use from the install window onward.
