Good morning, today the company I work for has suffered a cyber attack, all windows 7 and 10 operating systems servers and computers have been affected by the LECHIFFRE ransomware. Servers no longer respond to commands, we can't even take them remotely. Customers have practically all disk encrypted and applications do not work. We used several antivirus and antimalware products but no one found the virus on client workstations. We tried to run the tool you developed in 2016 but it did not recognize any of the encrypted files. We are talking about 700 computers between desktops, clients and servers.
