Kaseya was qualified since a key functionality of VSA is to thrust application and automated IT responsibilities on request, without the need of checks.
The hackers liable are now issuing varying ransom requires to its victims. REvil is demanding $44,999 from victims if their endpoint has been strike, according to Sophos security researcher Mark Loman.
