On March 23, 2025, an unprecedented cyberattack paralyzed the online services of Ukraine's state railway network, known as Ukrzaliznytsia. This cyberattack in Ukraine, described as one of the largest in the company's history, temporarily took down its website and mobile application, making ticket purchases difficult and affecting train operations.
However, the rapid response of the Ukrzaliznytsia teams in Ukraine allowed online services to be restored after 89 hours of uninterrupted work against the cyberattack, although certain technical issues persist due to the high volume of users trying to access the platform.
This cyberattack was not an isolated incident. The war between Ukraine and Russia has seen a significant increase in cyberattacks, where both nations have turned to cyber warfare as an extension of their military confrontation. Cyberattacks on critical infrastructures, such as railway networks, are now a common tactic used to disrupt the normal functioning of countries in conflict.
In this context, the cyberattack on Ukrzaliznytsia not only had national repercussions but also reflected the growing vulnerability of digital infrastructures to hostile actors. Below, ITD Consulting provides details of this cyberattack in Ukraine.

The Cyberattack: Origin and Scope
The cyberattack that affected Ukrzaliznytsia was identified as a large-scale and highly sophisticated attack, allegedly carried out by "the enemy," as the company itself mentioned in its public statement. The magnitude of the cyberattack took offline not only the ticket sales services but also other essential digital platforms for the company's daily operations.
During the first day of the cyberattack, Ukrzaliznytsia's website and application were completely inaccessible, which caused great frustration among users who depended on these services for their travel. Although the company initially described the cyberattack as a "technical failure," it soon acknowledged that it was a cyberattack specifically targeted at its digital systems.
The magnitude and sophistication of the cyberattack caused the company's operations to come to a halt for several hours, highlighting the importance of protecting digital infrastructures during times of conflict. The cyberattack was quickly detected and confirmed by Ukrainian authorities, who worked together with cybersecurity experts to contain and mitigate the damage.
The cyberattack had an immediate effect on the country's railway services. Although trains continued to operate normally, the passengers' inability to buy tickets online disrupted the usual passenger flow and led to an increased influx at physical ticket counters, which also became overwhelmed.
However, Ukrzaliznytsia's quick response allowed for a partial recovery of online services in just a few days, minimizing the long-term impact of the cyberattack. The restoration of service after the cyberattack was made possible thanks to the joint effort of various government sectors and technology companies that provided their support.
Cyberwarfare in the Ukraine-Russia Conflict
The cyberattack on Ukrzaliznytsia is not an isolated case in the context of the war between Ukraine and Russia. Since the beginning of the large-scale conflict, both countries have employed cyberattacks as part of their military strategy.
Russia, in particular, has been accused of carrying out cyberattacks against various Ukrainian infrastructures, including the energy system, telecommunications, and now, transport networks. These cyberattacks have become a key tool in modern warfare, as they can cause significant damage without the need to deploy physical troops.
Cyberattacks on critical infrastructures like railway systems, electrical grids, and power plants can paralyze an entire nation, affecting not only the economy but also the morale of the population and the government's ability to respond. In a war scenario, manipulating transport networks is especially effective, as it can disrupt the supply of resources, hinder the movement of forces, and create chaos in the logistics system.
Ukraine, for its part, has significantly improved its cyber capabilities since the beginning of the war, establishing a specialized cyber defense team that has worked tirelessly to protect the country's digital infrastructures. Since 2014, the Ukrainian government has strengthened its technological infrastructure and collaborated with international allies to improve its cybersecurity.
The creation of a national cybersecurity agency was a fundamental step in the fight against cyberattacks, but as the conflict intensifies, the need for real-time protection remains a priority. However, cyberwarfare remains an ongoing battle, with both sides seeking vulnerabilities to exploit in their opponents.
Russian cyber actors, for example, have developed sophisticated infiltration tactics, including the use of malware, ransomware, and phishing techniques targeting critical Ukrainian systems. Ukraine's cyber defense has faced an increasing challenge as attackers not only aim to disrupt services but also seek to steal vital information for military efforts and national security.
Russia's Cyber Strategy
Russia has historically been one of the most advanced nations in terms of cyber capabilities, with a strategic focus on using technology to gain advantages in international conflicts. In the case of Ukraine, Russia has turned to cyberattacks as a way to destabilize the Ukrainian government, weaken its infrastructure, and reduce the morale of the civilian population.
This has translated into cyberattacks not only on critical energy and transport systems but also on government institutions and media outlets. The cyberattack on Ukrzaliznytsia is yet another example of how Russia has expanded its war against Ukraine into the digital realm.
Moreover, cyberattacks on transportation infrastructure aim not only to paralyze travel and commerce but also to undermine the country's ability to mobilize and defend itself. The disruption of railway services, vital for logistics and the transport of goods, has a direct impact on the Ukrainian economy and its ability to withstand military attacks.
The lack of access to online platforms, especially for ticket purchases and route scheduling, also generates mistrust and disorganization among citizens. In the age of digitalization, cyberattacks are becoming increasingly efficient in eliminating the need for physical invasion.
Through cyberwarfare, Russia can weaken Ukrainian infrastructure without risking the lives of its own soldiers. This type of attack allows Russia to act more stealthily and unpredictably than conventional attacks, complicating Ukraine's and its allies' defensive response.

Ukrzaliznytsia’s Response: Restoration of Services and Subsequent Challenges
Following the cyberattack, Ukrzaliznytsia faced the challenge of quickly restoring its online services. The company managed to recover its website and application in a record time of 89 hours of continuous work against the cyberattack, demonstrating the capability of the company's technology team to handle extreme situations.
However, despite the partial restoration of services, the company warned of “temporary technical disruptions” due to the high demand for tickets, making it difficult for users to access the systems. The fact that trains continued to operate normally during the cyberattack is a testament to the resilience of Ukrzaliznytsia's physical infrastructure.
Although online ticket sales were temporarily suspended, rail transport did not stop, allowing operations to continue despite the difficulties. This highlights the importance of redundant systems used to ensure that, even in the event of a cyberattack, physical operations continue functioning.
However, the cyberattack also highlighted the need for Ukrzaliznytsia to invest more in cybersecurity to prevent future incidents of this kind. Businesses and government infrastructures in Ukraine must be prepared to face an increasing threat of cyberattacks as the conflict with Russia continues and intensifies.
Moreover, communication with users must improve in crisis situations, such as during a cyberattack. The downtime of services and lack of accurate information caused uncertainty among citizens, which increased the tension. Despite the restoration of online services, cybersecurity incidents remain an ongoing concern.
Cyberattacks are becoming more sophisticated, and the tactics used by attackers adapt to vulnerabilities in the security systems of infrastructures. In this context, cybersecurity experts have recommended constant updates to digital defenses and strengthening emergency response protocols.
