Country-level precision. botnet.cl stores the target country, never a city or coordinates, so the marker sits at the country's center.

What this method does

Potassium vector 15 sends UDP datagrams through its own registered payload handler. Option 7 selects a fixed port, random port, or list of destination ports.
