Helsinki, May 11, 2026 – The Europe Today: A cyber breach at Finland’s state information technology provider Valtori affected the Finnish Defence Forces and the Office of the President, according to documents obtained by Finnish broadcaster Yle.
The incident, which is being investigated as suspected espionage and aggravated unauthorised access to computer systems, involved a breach of a mobile device management service widely used across the Finnish government.
Valtori disclosed the breach in February and said approximately 50,000 users were affected. The agency stated that devices connected to Finland’s secure government communications network were not compromised.
Documents reviewed by Yle indicated that several security authorities were impacted by the cyber intrusion. The Office of the President reported that information linked to more than 50 individuals had been exposed, while Finnish Customs made a similar assessment in documents cited by the broadcaster.
Information concerning the Finnish Defence Forces was redacted from the released records.
The National Police Board of Finland estimated that information related to between 16 and 30 people had been exposed. According to documents cited by Yle, police authorities said the compromised material included identity information connected to official duties rather than broader organisational data.
Valtori chief executive Hannu Naumanen told Yle that no information from Finland’s secure government network had leaked.
The breach targeted a mobile service maintained by Valtori and used extensively within state administration for managing government-issued devices. According to information published by Yle and earlier statements from the agency, the leaked data included personal and contact details, country-level location information and records of software installed on devices.
Several Finnish ministries were also affected by the incident.
Finland’s National Bureau of Investigation, commonly known as KRP, is leading the investigation into the cyber breach.
