A 15-year-old boy is alleged to have changed grades, turning 5s into 6s, from his home in Italy, and to have interfered with tanker routes in the Mediterranean; he was identified through an investigation coordinated by the Polizia Postale and the prosecutor and was reported (an allegation). The Ministero dell’Istruzione e del Merito said checks showed no access to its own systems, that the case most likely involved the electronic register, and that each school chooses and contracts its register supplier autonomously. The Ministry said it was in contact with the Polizia Postale and urged schools to keep attention on digital security. Who first noticed is not stated in source beyond a complaint that opened the file. Whether the register was changed is not stated in source.
