The day that the supermarkets europeans lost millions in food: coordinated Attack systems, IoT
November 2, 2026, early morning
Customers of supermarkets in 8 european countries entered their local stores, and they noticed something strange: the fridges were warm. The freezers were hot. All the food was rotting in real-time.
What began as a ‘technical problem’ became the evidence of a coordinated attack on critical infrastructure of food that affected millions of people.
What happened
The attack
FACT (according to Al Jazeera and ABC News):
Supermarkets in at least 8 european countries reported that their cooling systems were taken remotely and configured to extreme temperatures.
A supermarket in Sweden reported specifically:
- Refrigerators and freezers set to 50°C (122°F)
- Fully committed
- Coordination coordinated indicating simultaneous attack, not isolated incidents
FACT: The loss is massive — million euros in perishable food supplies destroyed.
Scale of the attack
SPECULATION CONTROLLED (because we do not have exact numbers of all locations):
- 8-affected countries
- Potentially hundreds of supermarkets
- Decades of loss in the products
- Estimate: tens to hundreds of millions of dollars in food destroyed
Why it was possible to
Vulnerability 1: IoT without security-in-depth
Refrigeration systems in supermarkets typically have:
- Remote access for monitoring and maintenance
- Internet connection for alerts of temperature
- Little or no MFA for critical access
- Default passwords frequently not changed
If an attacker gets the credentials via phishing, brute force, or data breach), you can:
- Remotely access
- Modify temperature settings
- Paralyze alarm systems
Vulnerability 2: No correlation between systems
The supermarkets typically have:
- Cooling system isolated (temperature control)
- Alarm system isolated (alerts, temperature)
- Administrative system isolated (monitoring management)
If the attacker takes control of the cooling system but it disables the alarms simultaneously, no one realizes until the food is ruined.
Vulnerability 3: Lack of limits on changes
SPECULATION CONTROLLED: we don’t know exactly how the attacker changed temperatures, but patterns suggest:
- Without validation of extreme changes (change to 50°C without confirmation of security)
- Without real-time alerts of changes anomalous
- Without speed limit changes (change temperature in seconds vs. minutes)
The impact
Beyond the lost money
While the financial loss is significant, the real impact is more profound:
FACT: Millions of people were affected by:
- Reduction of food availability
- Price increases (reasurtimiento emergency)
- Loss of trust in supply chain
ANALYSIS: If the systems of food can be hacked, what more can you be hacked?
- Water systems
- Energy systems
- Transport systems
How it happened coordination
SPECULATION CONTROLLED: The fact that 8 countries were attacked simultaneously suggests:
- Same attacking group (or multiple groups coordinated)
- Access pre-positioned (credentials compromised in advance)
- Coordinated execution (same time to avoid detection)
- Knowledge of infrastructure (know which brands of refrigeration systems use the supermarkets)
This is not an attack random. It is social engineering + recognition + coordinated execution.
How to 24Cevent would have helped
If the supermarkets would have had a system of detection of anomalies in real-time:
Second 0-5 access(anomalous):
- Alert: ‘remote Access to the cooling system from unknown IP’
- Correlation: ‘This access is 1000x more anomalous to normal patterns’
- Action: auto-Lock + notification on-call
Second 5-30 (change anomalous):
- Alert: ‘Temperature set to 50°C (this is a change of -25°C)’
- Correlation: ‘This change is outside of normal range, without the approval of maintenance’
- Action: automatic Rollback + escalation critical
Second 30-60 (coordination detected):
- Correlation: ‘Multiple supermarkets in 8 countries with the same pattern of attack’
- Analysis: ‘coordinated Attack in progress’
- Action: CRITICAL INCIDENT + notice to regulators
Result: instead of destroy millions in food, destroy hundreds of euros before you contain.
The critical question
Who is attacking the supermarkets european, and why?
SPECULATION CONTROLLED: The sources do not identify the attacker, but patterns suggest:
- Actors sponsored by states — coordinating multi-country, technical knowledge, sophisticated
- Group of criminals organized — economic extortion
- Proof-of-concept demonstration of ability before the attack to be ‘real’
However, this is speculation. Until authorities published forensic analysis, we do not know who it was.
Conclusion: critical Infrastructure vulnerable
This attack demonstrates that the infrastructure of food is just as vulnerable as any other system.
The supermarkets, distributors, food, and supply chains:
- Increasingly rely on systems, IoT connected
- Often prioritize costs over security
- Rarely are defense-in-depth
The next wave of attacks will probably be:
- Water systems (configure chlorine to toxic levels)
- Transportation systems (disable brakes, paralyze vehicles)
- Energy systems (disable protections)
The question is: When do we realize that critical infrastructure needs to detection of anomalies in real time, not on time, a manual?
