the STJ ransomware attack (2020)
loresecuritygovernance & risk
The November 2020 ransomware incident at Brazil's Superior Court of Justice, attributed to RansomExx, which encrypted the court's case files, suspended proceedings and deadlines, and took roughly two weeks to restore.
Recovery was possible because backups survived, which is the whole lesson in one clause. Support came from the Federal Police, army intelligence and Microsoft, and the judiciary responded by standing up a body to address protection across the courts. Careful accounts note that the court never publicly confirmed a ransom demand, so descriptions of the extortion side rest on reporting rather than official statement - a distinction worth preserving when this case is cited.
