Re: There's another weasel clause right there
My bet is that they were actually performing a data/systems check for GDPR (a little late) and in that process they found they had been breached last year. So now they know about the breach, they have to report it in under 72 hours. My view is that it points to the theory that they have relevant event logging, but nobody was monitoring it, or, if there was an alert, it was missed or ignored? Either way, seems like a cock-up..
