On Friday, hackers identifying themselves as “Lapsus$Group” took down several systems within Brazil’s health ministry. At this point, it looks like a ransomware attack but the possibility exists that it was, in fact, a way to destroy the government’s collection of vaccine information.

Reuters reported on the story:

Brazil’s health ministry said its website was hit on Friday by a hacker attack that took several systems down, including one with information about the national immunization program and another used to issue digital vaccination certificates.

The alleged hackers, calling themselves Lapsus$ Group” posted a message on the website saying that internal data had been copied and deleted. “Contact us if you want the data back,” it said, in an apparent ransomware attack.
