Kickstarter, founded five years ago, has collected $982 million for more than 56,000 projects, according to its website. It says it has collected pledges from more than 5.6 million people.

The breach comes after discount retailer Target Corp. said it believes hackers infiltrated the computers of one of its vendors and installed malicious software in Target’s checkout system for its 1,800 US stores.

Experts believe the thieves gained access during the busy holiday season to about 40 million credit and debit card numbers from Target customers.

They also got the personal information — including names, e-mail addresses, phone numbers, and home addresses — of as many as 70 million customers.
