French Police Arrest HexDex Hacker Over Mass Data Theft and Leaks

French police arrested a 20-year-old hacker using the alias HexDex who is accused of stealing data from dozens of organisations — including about 15 sports federations, the Ministry of Education's Compas trainee‑teacher system (affecting 243,000 employees), the national firearms database (SIA), police e‑training, and multiple companies and charities — and posting the stolen information on forums such as Breachforums and Darkforums; law enforcement seized his devices and darkforum account while forensic analysis continues to establish the full extent of the compromises.
