This little gimmick cost Ahold in the Netherlands an estimated 300 M€ a few weeks back. Enough money for any firm to set the engineers to work? Where they waiting it out? Having read some more… another part of Ahold (the Belgian part) was hit and has (only now…) taken all fridges down from the internet. What is IT risk doing in a firm like that? Internet of Shit is a decade old. I am not amazed non tech sectors are perhaps a bit slower in IT risk management. I am amazed that an ongoing attack situation can still cause trouble 4 months after publication and months after board level headline grabbing numbers are widely publicized.
Me and my crew (yet to form ;) will visit any fridge for a measly 100 K€ a pop to take them offline. Book early, because once the script kiddies hit, we are on the road.
