Investigation Underway Into France Supermarket Cyberattack

An investigation is underway into an unprecedented cyberattack on hundreds of French supermarkets that is still spreading across the country.

Hackers are taking over refrigeration systems, overriding temperature settings and pushing some refrigeration units above 120 degrees while stores were closed.

Now, many are worried about how vulnerable these systems could be in any country.
