No zero-day required

Overnight on Oct. 11-12, attackers changed refrigeration settings at more than 700 supermarket sites in France. Freezers went into defrost, food spoiled and some equipment caught fire. French officials put the losses at tens of millions of euros.

The attackers didn’t need a new vulnerability. Danfoss said most of the controllers hit were older models it no longer updates. Others were current models still running old firmware, although a fix had been available for months.

France’s great defrosting: An inconvenience or a demonstration of how vulnerable we are?

Exposed equipment controls can cause physical damage and prolonged service failures. Recovery depends on safe operations, replacement capacity and trusted access.

What devices on your network fall outside anyone’s update process? Facilities teams or contractors may maintain them, while IT owns the network and the business absorbs the losses. Are you at risk because of old firmware?
