> The attack destroyed over 47 TB of critical data,
I'm very dubious that there would be such an amount of “critical” data pretty much anywhere, besides the banking and insurance sector. And particularly not at a drone manufacturer.
If you focus only on data with high-uptime requirements, no probably not 50 TB.
If you include low-uptime requirement but low-replaceability stuff like all the products' mechanical, electrical and software designs, documentation and artifacts? Easily 50 TB.
