brazil's civil defense system transmitted emergency mass alerts to millions of residents on june 20–21, containing phrases including 'misantropi' and explicit references to an 'alien attack' — residents in belo horizonte received a message reading 'alien attack people we have arrived.' no official explanation has been issued that accounts for the content of the messages. emergency alert systems are not easily hijacked or misfired with specific narrative content; the unusual phrasing and geographic distribution of the alerts make this structurally anomalous regardless of cause.
