The computer systems of Broward County schools in Florida were attacked by Conti malware. For decrypting the data, as well as in order to avoid publishing the stolen personal information, the attackers demanded a ransom in cryptocurrency.
Malware attacked systems in early March, writes Infosecurity.
Initially, the hackers asked for a ransom in the amount of $ 15 million. After two weeks of negotiations, representatives of the district offered to pay the extortionists $ 500,000, but the latter did not agree and stopped communicating with the victims.
As it became known now, Conti operators are asking for a ransom of $ 40 million.
County officials said they did not pay the ransom and did not have evidence that the hackers gained access to any personal information.
Earlier, the hacker group REvil encrypted the files of the Taiwanese company Acer and demanded to pay $ 50 million in Monero.
