Cyber-attack on railway network in Poland

At the end of August, hackers managed to break into Polish rail service frequencies, paralyzing traffic in the northwest of the country for one night. An estimated twenty railroads were affected.

The Internal Security Agency (ABW) and the Polish Police are investigating an unauthorized use of the system in rail traffic management, Stanisław Zaryn, deputy coordinator of special services, told the news agency. The signals were interspersed with a recording of the Russian national anthem and a speech by President Vladimir Putin, which would make the origin of the attack clear.

Since the beginning of the Russian invasion of Ukraine, Poland's railway system has represented a crucial transit infrastructure for Western countries' support of Ukraine. Zaryn, a senior Polish security official, explained that the attacks are part of a broader activity carried out by Russia to destabilize Poland.
