Sources: 4. Developments: 2. Croatian authorities arrested a 33-year-old Serbian businessman, Georgije V., on suspicion of conducting serious cyberattacks against various Croatian public authorities and companies. The investigation by the Zagreb County State Attorney's Office led to a court order for investigative detention due to concerns regarding flight risk and the potential for obstructing justice. Subsequent details revealed that the suspect is allegedly linked to Serbia's Security Intelligence Agency (BIA). The breaches reportedly targeted sensitive systems, including the Croatian Ministry of the Interior, the Tax Administration, the Health Insurance Fund, and the e-Citizens platform. Investigators identified that the attacks utilized a Serbian IP address and a Swedish server hosted by a company in Belize. While Croatian officials, including Minister Tomo Medved, have praised the response of the security and intelligence community, the full extent of the impact on national security remains under investigation. Legal counsel for the suspect is currently contesting the pre-trial detention order. ## Timeline ### 2026-08-07: Serbian businessman arrested in Croatia for alleged state-linked hacking A Serbian businessman has been arrested in Croatia on suspicion of hacking various state agencies and being linked to the Serbian Security Intelligence Agency (BIA). 2 sources. https://clstr.news/cluster/serbian-businessman-arrested-in-croatia-for-alleged-state-linked-hacking ### 2026-08-06: Croatian Minister Tomo Medved Praises Security Response to Hacker Croatian Minister Tomo Medved praised the security services for lawfully detaining Serbian hacker Georgije V., suspected of major cyber attacks on Croatian firms and authorities, after the Zagreb State Attorney 2 sources. https://clstr.news/cluster/croatian-minister-tomo-medved-praises-security-response-to-hacker --- Cite as: Cyberattacks against Croatian state institutions.
