If there's one company next to your bank you don't want to have a security flaw it's your Internet service provider. It stores your name, address, billing information, everywhere you've gone on the Internet and information about your connection that could let a hacker snoop on you.
An 18-year-old security researcher named Eric Taylor discovered one such flaw in the fourth largest Internet provider in the country. The ISP fixed it right away, but the flaw had been around for a long time before anyone noticed, so who knows what information was stolen.
The ISP is Charter Communications, and it serves 4.7 million customers. After reviewing the flaw, Charter says it potentially affected fewer than a million customers, and didn't expose any payment information.
However, according to Taylor, the flaw did give away a user's full name, email address, physical address and Internet hardware information. Plus it let hackers create additional usernames, user accounts and email addresses under a user's account. From there, they could take over the entire account.
