Popular crowdfunding site Kickstarter announced on its website Saturday that it had been hacked.
Information about Kickstarter's customers, including e-mail addresses, phone numbers and passwords, were accessed, though no credit card data had been breached.
Kickstarter said the security breach has been closed and recommended that its users create a new password.
"We're incredibly sorry that this happened," Yancey Strickler, Kickstarter's CEO, said in the notice on the website. "We set a very high bar for how we serve our community, and this incident is frustrating and upsetting. We have since improved our security procedures and systems in numerous ways, and we will continue to do so in the weeks and months to come. We are working closely with law enforcement, and we are doing everything in our power to prevent this from happening again."
