Slater and Gordon says its preliminary investigation of a rogue email sent to the entire firm which criticised senior executives and included a spreadsheet detailing the pay of its entire workforce was a “lone wolf” incident and not part of co-ordinated cyberattack.

The Australian Financial Review can also reveal that chief executive Dina Tutungi told staff in an emergency firm-wide meeting on Friday hours after the rogue email was sent that Victoria Police and external cybersecurity experts had been called in to investigate the matter.
