The Lockbit ransomware gang has attacked Sefaz-RJ. The Secretary of State for Finance of Rio de Janeiro confirmed that the organization is grappling with a ransomware attack on its systems. The LockBit ransomware group has claimed responsibility for targeting government office systems and has allegedly stolen approximately 420 GB of data. The group has threatened to release the stolen data on Monday. In a statement to The Record, a spokesperson for the Secretary of State for Finance of Rio de Janeiro revealed that they have reached out to the law enforcement agency responsible for handling digital crimes in Brazil. This action was taken after the cybercriminal behind the breach issued threats against their systems. "The attacker demanded payment to prevent the disclosure of data purportedly stolen from Sefaz-RJ's systems. The amount of data in question represents only 0.05% of the Secretariat's stored data," stated the spokesperson. Rio de Janeiro is the second-largest city in Brazil, following São Paulo, and serves as the headquarters for various state-owned companies, including Petrobras, Eletrobras, Caixa Econômica Federal, National Economic and Social Development Bank, and Vale. Renowned as one of the financial centers of South America, the city ranks 30th in terms of GDP among all cities worldwide. In 2021, Rio de Janeiro exported goods valued at $32.5 billion. The Undersecretariat for Information and Communication Technology (SUBTIC) informed The Record that they had offered their assistance to the police in conducting the investigation. "Since 2020, SUBTIC has been prioritizing the enhancement of information security, which is evident in the limited impact of this attack. The effectiveness of the measures we have implemented has contributed to this outcome," added the spokesperson.
