The Harris Federation, which is based in Croydon and operates 48 primary and secondary academies, reported the crippling attack over the weekend.

It is understood Campari was struck with Ragnar Locker, a sophisticated and relatively new form of ransomware first observed in 2019 affecting Microsoft Windows machines and associated with a hacking group of the same name.

The UK’s cybersecurity agency has issued an alert to schools, colleges and universities about an increase in hacking attempts around the start of the new academic year.

Attackers continue to use the same methods that worked for them long before 2020: find a way in, then target privileged access to unlock doors.
