  • Millions of Brazilians received an unauthorized government alert
  • The text simply read ‘misanthropi4’ and it’s unknown who sent it
  • The government has denied it was responsible, pointing towards hackers

If you’re based in the US, you might know about AMBER alerts, also known as Wireless Emergency Alerts, which are mass-broadcast messages sent to every smartphone in a designated area. Several other nations have similar platforms in place, including Brazil — but many Brazilians recently learned that their emergency alert system wasn’t quite as secure as they might have hoped.

In the early hours of Saturday morning, millions of Brazilians were jolted awake by a mysterious message from the country’s alert system. The alert level was classified as “extreme,” and concerningly, it’s thought it was the work of hackers rather than any official body.

The message, which was sent to civilians in the southern state of Paraná and the cities of São Paulo and Rio de Janeiro, among others, simply read “misantropi4.” That’s an approximation of the Portuguese word “misanthropia,” (with the final A swapped for a 4). As with the English word “misanthropy,” it means a hatred or distrust of humanity.

The message was accompanied by a loud alarm sound normally reserved for particularly severe thunderstorms. Since the text was sent shortly after midnight local time, it ensured that many people were woken up in the middle of the night.

Brazilian authorities said that the emergency message system was taken offline after a probable hacker attack, suggesting that this was more than just a simple text sent out in error by the government. Indeed, there was no event or natural disaster serious enough to warrant the alert being activated at the time, which further points towards bad actors being responsible.

A potentially devastating attack

The fact that hackers were able to breach a government system that has the potential to communicate with every mobile device in a given area of the country has worrying implications, both for the ways civilians could be manipulated and for the security of government institutions as a whole.

A text from a known government source is likely to be trusted more than one from an unknown number. With access to Brazil’s emergency broadcast system, hackers could potentially send out fraudulent messages that might have a larger impact than normal. That opens the door for all kinds of nefarious activities.

For now, this attack seems to have had a relatively minor impact. For many Brazilians posting on social media, the text was confusing more than anything else.

Last-Educator3947 on Reddit, for example, said “I live in the town where the alert was first sent. It happened five minutes after the Brazil x Haiti World Cup game. My anxious brain associated misanthropy with a violent attack on the people celebrating in the streets after the game. I thought it was an incel Discord hacker sending a message to start a ‘The Purge’-style attack.” They then added: “I’m laughing now but I barely slept last night.”

Reddit user Magnon, meanwhile, summed up the situation by saying that it, “Sounds like an anime villain just spawned.”

According to the International Cyber Digest newsletter on X, this breach could be linked to a previous hack of a Brazilian government employee who was infected with an infostealer. International Cyber Digest claims that stolen credentials included government logins, emails, developmental and staging environments, and more.

Whether or not this is what gave hackers access to the Brazilian government’s alert system isn’t yet known. Either way, it demonstrates the power that hackers can accrue if they find a way into supposedly secure governmental systems. While this alert saga turned out to be relatively harmless, that might not be the case next time.
