The impact of the Co-op cyber attack has been horrendous: in the barely two months after the Co-op cyber attack sales fell £206m, wiping £80m off the bottom line in its first half results and £120m for the full year.

But let’s look on the bright side. That’s a lot less than Marks & Spencer’s estimated £300m losses. And the damage could have been so much worse. ‘Zoning’ meant online sales, tills and the wholesale IT systems were maintained. And decisive action meant while the hackers downloaded the personal details of its (then) 6.5m members, they were unsuccessful in installing ransomware.
