Vienna, Austria — April 16, 2026 The trial of Egisto Ott, former head of Austria’s now-defunct BVT intelligence service, resumes Monday amid revelations that a 2020 data leak may have compromised the personal information of over 36,000 Interior Ministry employees, in what prosecutors call one of the country’s worst-ever data breaches.

The Scope of the Breach

The Vienna Regional Court will examine allegations that Ott violated secrecy laws by sharing an electronic personnel directory containing sensitive data on all 36,368 Interior Ministry employees as of February 1, 2018. The directory included personal and employment-related details, raising concerns about misuse by political or foreign intelligence networks.

Investigators traced the leak to a USB stick seized during a September 2021 raid at the home of Hans-Jörg Jenewein, a former Freedom Party (FPÖ) lawmaker. Jenewein claimed the data was "anonymously sent to him," but prosecutors suspect the breach may have extended to Russian intelligence services.

Legal Proceedings and Notification

Wolfgang Wohlmuth, spokesperson for Austria’s Office of the Public Prosecutor (OStA), confirmed that the 36,368 affected employees were notified via the judiciary’s Ediktsdatei system, a legally permissible method under Section 83, paragraph 5 of the Code of Criminal Procedure.
