Popular online fundraising website Kickstarter reported a security breach to its users, making sure to say that no personal account information was stolen.

“On Wednesday night, law enforcement officials contacted Kickstarter and alerted us that hackers had sought and gained unauthorized access to some of our customers’ data,” stated Kickstarter CEO Yancy Strickler in a post that was sent out to Kickstarter users. “Upon learning this, we immediately closed the security breach and began strengthening security measures throughout the Kickstarter system.”

“No credit card data of any kind was accessed by hackers,” Strickler stressed. “There is no evidence of unauthorized activity of any kind on your account.” However, the company has reset all users’ Facebook login credentials since some of the information stolen included email addresses, user names, mailing addresses, phone numbers and encrypted passwords. “Actual passwords were not revealed, however it is possible for a malicious person with enough computing power to guess and crack an encrypted password, particularly a weak or obvious one,” stated the company.

“We’re incredibly sorry that this happened,” wrote Strickler. “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.”
