‘The extent of sophistication right here was extraordinary,’ he mentioned.

When the cybersecurity agency Mandiant finishes its investigation, Voccola mentioned he’s assured it can present that the criminals did not simply violate Kaseya code but additionally exploited vulnerabilities in third-party software program.

Earlier, the FBI mentioned in a press release that whereas it was investigating the assault its scale ‘might make it in order that we’re unable to reply to every sufferer individually.’
