Greece ranked second in the European Union for new fraud cases referred to Eurojust in 2025, sending 237 cases, four fewer than Italy’s 241. The figures, seen by eKathimerini, come from Eurojust’s handling of cross-border cases brought by national authorities. The ranking counts new cases referred for judicial cooperation, not the overall scale of fraud in each country. Online fraud was the biggest category Eurojust dealt with in 2025, with 4,803 cases, including 1,894 newly referred cases. In cybercrime, Greece introduced 65 new cases, compared with 57 from Germany and 35 from Finland. Greece also took part in an early October international operation against the cyber-extortion group KillSec, linked to nearly 1,000 attacks worldwide. A 16-year-old man was arrested in Spain, and authorities in Athens identified an 18-year-old suspect believed to be the group’s programmer. Nine countries cooperated in the operation, investigators seized more than 110 terabytes of stolen data, and Greece’s Eurojust office took part in 1,311 cases in 2025. The prosecutor leading the Greece-based Eurojust office has been in the role since September 2022, and from January to September the office joined 124 fraud cases and 32 cybercrime cases.
