Actually, every single Yahoo account got hacked in 2013 The updated figure triples the scope of the breach.

The revised number vastly expands the scope of the historic hack, which had previously broken records as the world's largest data breach. The updated figure comes as the public is still reeling from back-to-back reports of data breaches at Equifax and the fast-food chain Sonic.
