Amsterdam – VEON Ltd. (NASDAQ: VEON, Euronext Amsterdam: VEON), a global digital operator that provides converged connectivity and online services, announces that its Ukrainian subsidiary Kyivstar has started restoring voice services on its mobile network as of 18.00 Kyiv time, following the widespread cyber-attack of 12 December 2023. 

The restoration will continue to progress gradually and in stages; and setbacks during the process are possible. Kyivstar technical teams are also working on the restoring data and SMS messaging services; and hope to gradually make these available within the next 24 hours. In parallel, the company is working in close cooperation with Ukrainian law enforcement agencies, government services, and the Security Service of Ukraine, to identify the circumstances of the attack. Earlier in the day, Kyivstar refuted unfounded claims that hacker groups shared social media, and confirmed that consumer data has not been compromised. 

VEON and Kyivstar are also conducting a thorough investigation to determine the full extent and impact of the incident, and to implement additional security measures to prevent any recurrence. The full financial impact remains not quantifiable at this stage as the restoration of services continue. 

VEON and Kyivstar thank Ukrainian government agencies for their immediate response and assistance in addressing the attack, and express their gratitude to Kyivstar customers, corporate clients, partners and industry colleagues for the overwhelming support they have shown on public and private channels. 

VEON and Kyivstar reiterate their commitment to keeping Ukraine connected and resilient.
