Websites under Brazil’s Ministry of Health (MoH) have suffered a major ransomware attack that resulted in the unavailability of COVID-19 vaccination data of millions of citizens.
Following that attack that took place at around 1 am today, all of MoH’s websites including ConecteSUS, which tracks the trajectory of citizens in the public healthcare system, became unavailable. This includes the COVID-19 digital vaccination certificate, which is available via the ConecteSUS app.
According to a message left by the Lapsus$ Group, which has claimed responsibility for the attack, some 50 TB worth of data has been extracted from the MoH’s systems and subsequently deleted. “Contact us if you want the data returned”, the message said, alongside contact details for the authors of the attack.
Just before 7 am, the images with the message left by the hackers were removed, but the websites remained unavailable
