I worked at Capital One. Hacks like this are most dangerous for low-income people.

  The Capital One breach announced recently compromised the data of 100 million Americans, which is nearly 40 percent of all U.S. adults. After the Equifax, Target, Home Depot, and Marriott hacks, it can be easy to shrug off the news of another leak, but one group of consumers is at particular risk in the Capital One breach: 80,000 Americans who applied for secured credit cards with the company.

  The hacker, Paige Thompson, gained access to personal information such as income, address, and credit scores for seemingly all recent applicants to Capital One credit cards. For secured card applicants, who tend to be low-income, bank account information was compromised as well.
