Let's imagine for a moment that the screen flickers, the cell phone only shows „No network“ and the checkouts at the supermarket remain dark. No card works anymore, no cash machine spits out bills. The idea sounds like something out of a thriller - but it is no longer science fiction. Cyber attacks on critical infrastructure are real, they happen every day somewhere in the world. We don't even notice most of them. But what if the next attack paralyzes not just one company, but entire regions?
This is where things get exciting for people who want to take precautions - for preppers, but also for anyone who simply wants to retain a degree of independence. Because while classic crisis scenarios such as power outages, natural disasters or supply chain problems often seem tangible, digital attacks remain invisible - until it is suddenly too late.
Cyber attacks: an invisible storm
Let's remember 2017: the „WannaCry“ virus paralyzed hospitals in the UK. Operations had to be postponed, patients had to be turned away. In Germany, it hit the railroads - display boards broke down and ticket machines went on strike.
The problem: our entire modern infrastructure is connected to the grid. Power stations, waterworks, banks, traffic management systems - everything is digitally controlled. An attack can trigger chain reactions that go far beyond a few failed computers.
A security expert once put it in a nutshell:
„The Internet is no longer an additional system - it is the system.“
What does this mean for everyday life?
A successful cyber attack can have completely different consequences depending on the target. Here are a few examples:
- Financial systems: Bank accounts unavailable, ATMs inoperable, cashless payments impossible.
- Supply: Supermarkets can no longer book deliveries, checkouts fail, cold chains break.
- Electricity and water: Worst-case scenario - digital attacks on network operators or pumping stations.
- Communication: Cell phone networks and internet providers can be paralyzed or massively restricted.
- Traffic: Airports, railroads, road traffic management systems - in chaos mode.
Here is a simple overview:
| Range | Possible consequences of a cyber attack |
| Banking | No online banking, no cash withdrawals |
| Food trade | Failure of cash register systems, supply bottlenecks |
| Energy | Power failures, faulty heating systems |
| Water | Problems with preparation and distribution |
| Communication | Collapse of the Internet and mobile communications |
| Healthcare system | Surgeries postponed, emergency room overloaded |
Why preppers in particular should take a look
For many, this scenario sounds like a worst-case scenario that is unlikely to happen. But even minor disruptions can be enough to disrupt everyday life. Cyber attacks differ from storms or floods in their insidiousness: You can't see anything coming. No stormy skies, no weather report to warn you.
And that is precisely why preparation makes sense. Anyone who has learned to get by without digital infrastructure for a few days or weeks has a clear advantage.
Practical steps: How to prepare
Of course, no one can protect a country's IT security alone. But you can cushion the impact for yourself and your own family.
- Be financially prepared
- Always have a small amount of cash in the house.
- If possible, not all the money in one account, but spread out.
- Alternative means of exchange (silver coins, durable goods) can also be useful.
- Securing basic services
- Food supplies for at least two to three weeks.
- Water reserves or means of water treatment.
- Backup power sources (power banks, solar chargers, generators).
- Secure communication
- Emergency handheld radios or simple walkie-talkies.
- Write down important telephone numbers and addresses on paper.
- Appointments with family or neighbors: „Where do we meet if everything is canceled?“
- Create analog redundancies
- City map or map instead of just Google Maps.
- Printed recipes or instructions (e.g. first aid).
- Paper calendars in case digital calendars fail.
An example from everyday life
An acquaintance of mine works for a large haulage company. A few years ago, their IT system was paralyzed by a Trojan. Nothing worked anymore: no route planning, no order acceptance, no invoicing. Within a few hours, hundreds of trucks were standing uselessly in the yards. The drivers didn't know where to go and the goods were left lying around.
It wasn't the end of the world - but it showed how dependent we have become on software. When something like this happens on a large scale, it only takes a few days until supermarkets are empty.
Psychological preparation
It's not just supplies that are crucial. Those who remain calm in the middle of a digital blackout have the best cards. Panic is contagious, but so is calmness.
This includes:
- Be aware in advance that systems can fail.
- Have a routine: „When this happens, I do this first, then this.“
- Staying in touch with others - neighbors, friends, family. Community is the strongest network in such situations.
A picture at the end
Sometimes I think of a simple parable: Our digital world is like a house made of glass. From the outside, it looks modern, bright and stable. But a single stone can be enough to create cracks that spread quickly. We can't reinforce the walls ourselves, but we can learn not to stand defenseless in the rain when panes break.
And that's what being prepared is all about: not living in fear, but having the freedom to remain capable of acting - even when the digital light goes out.
Conclusion: Cyberattacks are not just an IT issue for experts. They can change our everyday lives just as much as a power cut or a natural disaster. Those who are prepared - with supplies, cash, clear processes and a cool head - do not have to watch helplessly. And perhaps that is precisely the greatest advantage: not being surprised by the invisibility of the problem, but consciously strengthening your own weak points.
