Cyberattacks on Poland’s Rail System: A Closer Look
Introduction
The war between Ukraine and Russia since 2014 has witnessed the use of highly sophisticated hacking techniques by Russian hackers, aimed at destroying Ukrainian networks, disrupting satellite communications, and causing blackouts for Ukrainian citizens. However, the recent disruptions in Poland’s rail system, considered crucial for NATO support to Ukraine, seem to have been carried out using a much simpler method – forging a radio command to activate the emergency stop function in trains. This article will delve deeper into these incidents, examining the nature of the cyberattacks and their implications.
The Sabotage Incidents
Over the course of two days, more than 20 Polish trains were brought to a halt, raising concerns about a cyberattack. The Polish media and the BBC have labeled these incidents as such, and the Polish intelligence services are investigating them as acts of sabotage in support of Russia. The saboteurs reportedly inserted the Russian national anthem and parts of a speech by Russian President Vladimir Putin into the orders used to stop the trains.
The Significance of Poland’s Rail System
Poland’s rail system plays a vital role in providing Western weapons and aid to Ukraine as part of NATO’s efforts to strengthen the country’s defense against Russian invasion. Stanislaw Zaryn, a senior security official, acknowledges that there have been ongoing attempts to destabilize the Polish state for months. Consequently, the disruptions in the rail system are deeply concerning and raise serious questions about the security of such critical infrastructure.
The Cyberattack Misconception
Contrary to initial assumptions, upon closer examination, it appears that the disruptions in the Polish rail system did not involve a traditional cyberattack. Independent Polish-speaking cybersecurity researcher Lukasz Olejnik explains that the saboteurs simply used “radio stop” commands transmitted over the radio frequency to employ the trains’ emergency stop function. The lack of encryption or authentication in the radio system allowed anyone with access to commercially available radio equipment, costing as little as $30, to initiate the command.
The Technical Details
Olejnik points out that the process of sending the “radio stop” commands is relatively simple. Three tonal messages are sent consecutively, triggering the locomotive to stop once received by the radio equipment. The technical standards for trains in the European Union outline this command, and information about its execution has been circulating on Polish radio and train forums, as well as on YouTube for years. The accessibility and affordability of the required equipment make it a feasible tactic even for non-experts.
Improving Poland’s Rail Systems
Recognizing the vulnerabilities of the current system, Poland’s national transport agency plans to enhance the country’s rail systems by 2025, primarily by adopting encrypted and authenticated GSM cellular radios. These upgrades aim to prevent the misuse of radio commands and improve the overall security of the rail network. Until then, however, the relatively unprotected 150 MHz VHF system will continue to be used, posing a risk of further disruptions.
Unique Insights and Perspectives
While the recent cyberattacks on Poland’s rail system have attracted attention, it is crucial to recognize larger patterns in global cybersecurity. The incidents highlight the importance of securing critical infrastructure and the need for international collaboration to mitigate cyber threats. Here are some unique insights and perspectives on the subject:
- Cybersecurity is an ongoing battle, and attackers constantly adapt their strategies. As countries invest in advanced defense mechanisms, adversaries seek out vulnerabilities in less sophisticated systems, such as the radio-based command system in the Polish rail network.
- The incidents in Poland underscore the significance of encryption and authentication in critical infrastructure systems. Implementing robust security measures can help prevent unauthorized access and potential disruptions.
- Raising awareness about potential vulnerabilities can empower individuals and organizations to take proactive measures. By sharing information about known tactics like the “radio stop” command, the cybersecurity community can collectively work towards developing effective safeguards.
- International cooperation is crucial in combating cyber threats, particularly when attacks target infrastructure that supports regional defense efforts. Sharing intelligence, expertise, and technological resources can enhance the overall security posture of nations.
Summary
The recent disruptions in Poland’s rail system have exposed vulnerabilities in critical infrastructure, highlighting the need for enhanced cybersecurity measures. Contrary to initial assumptions, the disruptions did not involve a sophisticated cyberattack but rather the use of simple radio commands to trigger the emergency stop function in trains. These incidents serve as a reminder that securing critical infrastructure is an ongoing challenge and requires proactive measures. Poland’s plans to upgrade its rail systems by 2025 demonstrate the importance of encryption and authentication in safeguarding against potential threats. By understanding the specifics of these attacks, we can take steps to fortify critical infrastructure and work towards a more secure digital future.

since the war first Erupted between Ukraine and Russia in 2014, Russian hackers have at times used some of the most sophisticated hacking techniques ever seen in nature to destroy Ukrainian networks, Disrupt the country’s satellite communications.and even cause blackouts for hundreds of thousands of Ukrainian citizens. But the mysterious saboteurs who, over the past two days, have disrupted Poland’s rail system—an important piece of transit infrastructure for NATO support for Ukraine—seem to have used a far less impressive form of technical mischief: forging a simple radio command to the train that activates its emergency stop function.
On Friday and Saturday, more than 20 Polish trains carrying goods and passengers were stopped across the country, throughout what The Polish media and the BBC have called it a “cyber attack”. The Polish intelligence services are investigating the sabotage incidents that are said to have been carried out in support of Russia. The saboteurs reportedly interspersed the orders they used to stop the trains with the Russian national anthem and parts of a speech by Russian President Vladimir Putin.
After all, Poland’s rail system has served as a key source of Western weapons and other aid flowing into Ukraine as NATO tries to bolster the country’s defense against Russian invasion. “We know that for some months there have been attempts to destabilize the Polish state,” Stanislaw Zaryn, a senior security official, told the Polish Press Agency. “At the moment we do not rule out anything.”
But as disturbing as the rail sabotage has been, upon closer inspection the “cyberattack” does not appear to have involved any “cyberattack” at all, according to Lukasz Olejnik, an independent Polish-speaking cybersecurity researcher and consultant and author from the next book Cybersecurity Philosophy. In fact, the saboteurs appear to have sent simple “radio stop” commands over radio frequency to the attacking trains. Because the trains use a radio system that lacks encryption or authentication for those orders, Olejnik says, anyone with as little as $30 worth of commercially available radio equipment can transmit the order to a Polish train, sending a series of three acoustic tones at a frequency of 150,100 megahertz and activate its emergency stop function.
“There are three tonal messages sent consecutively. Once the radio equipment receives it, the locomotive stops,” says Olejnik, pointing to a document that describes the different technical standards for trains in the European Union and which describes the “radio stop” command used in the Polish system. In fact, Olejnik says the ability to send the command has been described for years on Polish radio and train forums and on YouTube. “Everyone could do this. Even teenagers troll. The frequencies are known. The tones are known. The equipment is cheap.
Poland’s national transport agency has declared its intention to improve Poland’s rail systems by 2025 to use almost exclusively GSM cellular radios, which do have encryption and authentication. But until then, it will continue to use the relatively unprotected 150 MHz VHF system, which allows for “radio stop” commands to be faked.
