In privacy news, the credit reporting agency Equifax said Thursday that a software vulnerability left personal information for 143 million people exposed to hackers, in one of the largest data breaches in U.S. history. Equifax said the information included Social Security numbers, driver’s license information, credit card numbers and other data. Bloomberg reports that just days after learning of the breach, three top Equifax executives sold about $1.8 million worth of the company’s stock—yet waited over a month to inform the public. Equifax’s share price plummeted in overnight trading after news of the data breach broke, losing nearly 15 percent of its value.
