Data breaches are a run-of-the-mill occurrence these days, but every now and then a breach rises to the level of jaw-dropping. For 2015, that was most certainly the Ashley Madison hack in August. Hackers were able to breach the site and obtain real names, partial credit card numbers, home addresses, phone numbers, and even sexual preferences for many users of the infidelity service, including some celebrities, personalities, and politicians.
Unfaithful adults weren't the only ones to have their info hijacked this year. Child electronics maker VTech also suffered a data breach affecting 4.8 million parents and as many as 200,000 children.
