First Ukrainian International Bank

First Ukrainian International Bank, widely recognised by its acronym PUMB, is a bank that delivers a range of financial products to individuals and businesses across Ukraine. Its core services include accepting deposits, extending loans, processing payments, and offering other standard retail and corporate banking solutions. The institution is headquartered in Ukraine, placing it under the jurisdiction of the National Bank of Ukraine. As a licensed bank, it participates in the country’s payment systems and contributes to the intermediation of funds within the economy. Its client base comprises both personal account holders and corporate entities seeking traditional banking facilities.

The bank is regarded as one of the major players in the Ukrainian banking sector, a status implied by its inclusion in a coordinated cyber‑attack that targeted nearly a dozen prominent Ukrainian financial institutions. While concrete metrics such as total assets, branch count, or customer numbers are not supplied in the available sources, its significance is inferred from the scope of the attack campaign. The institution operates under the regulatory oversight of the National Bank of Ukraine, which sets capital adequacy, liquidity, and conduct requirements for all banks in the country. Its market activities are concentrated domestically, with no explicit mention of overseas branches or subsidiaries in the provided material. Consequently, any description of its international footprint would be speculative and is therefore omitted.

On 27 June 2023, First Ukrainian International Bank suffered a distributed denial‑of‑service (DDoS) assault launched by the pro‑Russian hacktivist group NoName057(16). The attack formed part of a wider offensive against the Ukrainian financial sector, which the group asserted was a reaction to Ukrainian political debates about transitioning to a cashless society. The DDoS effort specifically aimed to overwhelm the bank’s online infrastructure, focusing on authorization systems, login portals, and customer‑service platforms. This disruption hindered clients’ ability to access digital banking services and highlighted the institution’s dependence on resilient cyber defenses. The episode underscored the increasing cyber‑threat environment confronting Ukrainian banks amid ongoing geopolitical tensions.

Details concerning the bank’s ownership structure, parent company, or subsidiary relationships are absent from the supplied information, so no definitive statements can be made about its corporate governance. As a result, any speculation about shareholdings, affiliations, or group membership is avoided to remain strictly factual.
