Monobank, the Ukrainian digital banking service, reported a suspension of transfers as a result of a large-scale disruption. The news outlet Strana.ua reported this development.
There is a clear statement that the bank has not initiated any corrective actions at this time.
In a Telegram channel post, Oleg Gorokhovsky, who is a co-owner of Monobank, indicated that the bank’s network infrastructure faced a powerful distributed denial-of-service (DDoS) attack. The message appeared in a publication on that channel, signaling a possible root cause for the operational pause.
Earlier, Ukraine’s Ministry of Energy reported that approximately two million people across the country lost electricity due to issues within the power system.
The outage episode occurred on the afternoon of May 30, when the power system operator experienced an emergency that triggered immediate electricity cuts.
The disruptions affected multiple regions, including Kyiv, Vinnytsia, Dnipropetrovsk, Kirovohrad, and Mykolaiv.
Further outages were reported in Odesa, Poltava, Kharkiv, Khmelnytskyi, and Cherkasy, as well as in the Kyiv-controlled areas of the Energodar-adjacent zone of the Zaporozhye region.
The Ministry of Energy added that this incident stands as the largest system-wide failure since February 2023.
Previously, Ukraine faced a broad breakdown of mobile communications that affected service across several regions, underscoring the country’s exposure to critical infrastructure stress in recent months.
Across these events, authorities and service providers are focused on restoring services, assessing the scale of the disruptions, and identifying any persistent vulnerabilities in both digital and energy networks. Observers emphasize the importance of redundancy, incident response readiness, and transparent communication as key factors in mitigating the impact on citizens and the broader economy.
