Thousands of Brazilians in a number of states were shocked and puzzled by emergency alerts sent to their cell phones in the middle of the night, some containing gibberish while others warned them to brace for an imminent alien attack.

The false alarms were sent between Friday night and early Saturday morning through Brazil’s Civil Defense Alert platform, a system normally reserved for serious warnings about floods, landslides, storms, and other emergencies.

People in several cities were awakened by ‘extreme alert’ notifications containing the word ‘misanthropy’ – meaning hatred or distrust of humanity – while others received messages that sounded less like public safety advice and more like the opening scene of a low-budget sci-fi film.

 

“Protect yourself: ALIEN ATTACK. Humans, we have arrived,” read the message received by some residents of Belo Horizonte, the capital of Minas Gerais state, according to G1 Globo. Another version warned of a supposed tornado in the metropolitan region.

 

There was, officials later clarified, no alien invasion. The real emergency, according to the National Civil Defense, was much more earthly: The alert platform had apparently been compromised.

 

The agency said the system was taken offline at 1:30 AM on Saturday after an unauthorized third party remotely triggered alerts to several regions of the country. The Federal Police launched a probe, as technicians work to restore the platform.

For many Brazilians, the first response was not concern but memes. Others were less amused, noting that the same alert system is supposed to warn people of real disasters and that a false ‘extreme’ message in the middle of the night could easily cause panic.

Residents in Belo Horizonte reportedly called Civil Defense, firefighters, and police in search of explanations after the alerts blared on their phones. Some said they woke family members or looked for safer rooms after seeing the tornado warning, while others quickly suspected a hoax after reading the extraterrestrial portion of the message.

The incident came at an awkwardly cosmic moment. Just days earlier, the Pentagon released another batch of declassified files on unidentified anomalous phenomena, the official term for UFOs, including witness accounts, photos, and videos of unexplained objects.

That release, however, came with the usual caveat that unexplained does not mean extraterrestrial. The Pentagon has maintained that the material contains no confirmed evidence of alien life, alien technology, or a government cover-up.
