The huge hack of Hong Kong toy company V-Tech continues to spread. V-Tech said today that hackers stole information of nearly 6.5 million children who used its toys. That number is up from 200,000, which is how many kids the company said were affected when it announced the hack on Friday. Hackers also stole data from about 5 million of the children’s parents. The stolen information includes names and birth dates, and may include photos of the children and chat logs from V-Tech’s toy tablets and their parents’ phones. Ben Johnson, the host of Marketplace Tech and the new podcast Codebreaker, explains the hack.
