The Target hack gets worse: Phone numbers, addresses of up to 70 million customers leaked

Target has updated its estimate of the number of customers affected by a massive data breach last month, saying that the personal information of as many as 70 million people was compromised as a result of the hack. The type of information breached now includes names, phone numbers and postal and e-mail addresses, according to a Target blog post.

The new figure is separate from the 40-million-person breach Target announced last month. Not everyone who was affected by the previously-reported breach may be affected by this new revelation, though there is likely to be overlap between the two groups.

The new numbers suggest that the hack affected nearly a third of the country. According to the U.S. Census Bureau, there are about 240 million adults in the United States. By that standard, the breach exposed the financial information of 29 percent of Americans.

Target's stock is down more than 1 percent at the time of writing.
