@cbsnews: Cyberattacks on grocery store refrigeration systems across Europe sent temperatures soaring this week, spoiling food and causing significant financial losses, CBS News’ Inaya Folarin Iman reports. It is the second such incident in less than a month. In October, hundreds of French stores were targeted in a similar attack that sent temperatures in some units soaring to 122° Fahrenheit, destroying a huge amount of food. The incidents have renewed wider concerns about the vulnerability of critical infrastructure and the growing risks of internet-connected consumer "smart" technology. It is not just essential systems such as electricity grids, healthcare databases and grocery store chains' refrigeration, which can have multiple layers of security and redundancy built in, but everyday appliances that are now connected to the internet.
