Polski Standard Płatności, operator of BLIK—Poland’s dominant mobile payment system—faced a DDoS (Distributed Denial of Service) attack that disrupted payment processing, causing intermittent transaction failures. The attack overwhelmed BLIK’s infrastructure, rendering services temporarily unavailable and affecting millions of users relying on the platform for daily transactions. While the system was restored by 6:30 PM on the day of the incident, the outage created financial inconvenience for customers, merchants, and banks, given BLIK’s role in processing 2.4 billion transactions worth PLN 347 billion (EUR 81.5 billion) in 2024 alone. The attack also targeted Poland’s broader settlement infrastructure, as confirmed by Deputy PM Krzysztof Gawkowski, indicating a coordinated effort to destabilize the country’s digital payment ecosystem. Though no data breach or permanent financial loss was reported, the disruption undermined trust in the system’s reliability, risked reputational damage, and highlighted vulnerabilities in critical financial infrastructure. A similar attack had occurred just days prior, suggesting a persistent threat.
