Brazil's Tribunal de Justiça do Estado do Rio Grande do Sul was hit with an REvil ransomware attack yesterday that encrypted employee's files and forced the courts to shut down their network.
Tribunal de Justiça do Estado do Rio Grande do Sul is the court system for the Brazilian state of Rio Grande do Sul.
"The TJRS informs that it faces instability in computer systems. The systems security team advises internal users not to access computers remotely, nor to log into computers within the TJ network," tweeted the TJRS court system.
These ransom notes are for the REvil ransomware operation, which BleepingComputer has independently confirmed was responsible for the attack.
This cyberattack is not the first ransomware attack on Brazil's court systems.
This past November, Brazil's Superior Court of Justice was attacked by the RansomEXX ransomware gang who began encrypting devices in the middle of video conference court sessions.
