First Ukrainian International Bank

First Ukrainian International Bank (PUMB) is a banking institution headquartered in Ukraine, operating within the national financial sector. The bank provides standard banking services to its customers, though specific product details or market segments are not elaborated in available records. Its status as a target in a significant cyberattack indicates it holds a notable position within Ukraine's banking landscape.

In June 2023, PUMB was specifically targeted by the pro-Russian hacktivist group NoName057(16) during a coordinated distributed denial-of-service (DDoS) campaign against the Ukrainian financial sector. The attack aimed to disrupt the bank's online infrastructure, focusing on authorization services, login portals, and customer service systems. This incident was part of a broader offensive that affected nearly a dozen major Ukrainian banks, which the group claimed was retaliation for political discussions regarding a shift toward a cashless society. The assault on PUMB's digital platforms resulted in service interruptions, demonstrating the vulnerability of financial institutions to ideologically motivated cyber operations. The group's public attribution and the scale of the campaign against multiple major banks underscore the event's significance within the context of ongoing cyber conflict related to the geopolitical situation in Ukraine. While the immediate operational impact on PUMB is noted, precise metrics such as duration of downtime or financial losses are not specified in the incident overview. This documented event represents a clear instance of hacktivist activity directly targeting the bank's critical online functions.
