Una task force internazionale dovrà cercare di far luce sugli attacchi informatici in decine di Stati in tutto il mondo, circa 150 secondo diverse fonti. Risultano colpiti privati, istituzioni, aziende, ospedali, in tutto 200'000 sistemi ha detto il diretto Rob Wainwright.
La ricerca dei responsabili appare difficile mentre gli esperti di Europol prevedono nuovi attacchi di hacker.
Un bilancio delle azioni è difficile da fare ma è sicuro che dovranno essere rafforzate le misure di protezione. Le richieste di denaro (estorsioni) per potere nuovamente accedere ai sistemi sono state relativamente poche. Ma il timore è che gli hacker potrebbero mettere in difficoltà ad esempio centrali di produzione elettrica, ciò che avrebbe effetti tangibili molto gravi. Finora i sistemi di protezione hanno retto bene. Fra i gruppi, Renault in Francia ha dovuto sospendere la produzione per diverse ore a Sandouville. Brutte sorprese potrebbe riservare l’attivazione degli ordinatori lunedi, alla ripresa del lavoro.
