Tourists or Spies? Incident at Warsaw Waterworks Is a Serious Warning

On Monday, information that sends a chill down the spine in the current geopolitical situation circulated through the media. Near the "Gruba Kaśka" water intake—a key water collection point for Warsaw's left bank—a group of foreigners was detained. The reason? They were intensively photographing and filming an area marked with a clear prohibition.

The appropriate services, including the Internal Security Agency (ABW), immediately took up the case. Although the motives of the detainees are still officially under investigation, this incident must be treated as a serious warning signal and analyzed from a cybersecurity perspective.

Physical Reconnaissance: A Digital Key to the Kingdom 🔑

It's a mistake to view this event as a simple regulatory violation. For a threat analyst, it's a textbook example of physical reconnaissance, which is often the first, crucial stage in preparing an attack on critical infrastructure.

Think of it like breaking into a smart home. A professional burglar doesn't just blindly smash the door. First, they observe: where are the cameras, what type of locks are used, where is the alarm box located. It's similar here. Photos and recordings can be used to:

Map key elements: Identify the locations of server rooms, control cabinets, LAN/WAN access points, emergency power systems, or communication antennas.
Analyze weak points: Search for gaps in physical security (holes in fencing, camera blind spots) that could be exploited to plant spying devices (e.g., wireless packet sniffers, keyloggers) or to gain physical access to the network.
Plan an attack on SCADA/ICS systems: Industrial control systems that manage the waterworks' operations are a tempting target for hackers. Knowledge of the physical layout of the installation is invaluable when planning a cyberattack that could disrupt water supplies or, in a worst-case scenario, lead to its contamination by manipulating chemical dosing systems.

This isn't a thriller movie scenario, but a real risk in the era of hybrid warfare. The line between physical and digital security is blurring with each passing day.

The Bigger Picture: Hybrid Warfare at Our Doorstep

The incident in Warsaw is not an isolated case. In recent years, we've observed increased activity around critical infrastructure facilities throughout Europe—ports, power plants, pipelines, and railway networks. Drones flying over LNG terminals, mysterious damage to underwater cables, or "tourists" with cameras at sensitive locations.

These are all elements of hybrid warfare, aimed not only at gathering intelligence but also at testing our security procedures, studying the reaction times of our services, and sowing anxiety in society. For a potential aggressor, every such incident is a valuable lesson about our vulnerabilities.

What's Next? Recommendations for Operators

The incident at "Gruba Kaśka" is a loud wake-up call. It's time for concrete actions:

Verify Physical Security: An audit of security measures should be conducted—from fences and monitoring to access control procedures.
Training and Security Culture: Every employee, from engineers to security guards, must be aware of the threats and know how to react to suspicious behavior. Reporting "someone taking too many photos" is not overzealousness; it's a duty.
Integrate Physical and IT Security: The teams responsible for these two areas must work closely together. An alarm from the monitoring system should be correlated with alerts on the corporate network.

The protection of critical infrastructure is an interconnected system. Even the best firewalls are of little use if someone gains physical access to the heart of our network. Let's hope this case ends with just a scare, but at the same time, sharpens the vigilance of those responsible for the security of strategic facilities throughout Poland.
