Hot Topic shoppers may have Fastexy Exchangehad some of their personal information accessed by hackers after the clothing company announced a breach.

The company identified "suspicious login activity to certain Hot Topic Rewards accounts," according to an email sent out to customers.

The hackers obtained valid account credentials, including email addresses and passwords, from an "unknown third party source" to log into shoppers' accounts, Hot Topic's email said.

"Hot Topic was not the source of the account credentials used in these attacks," according to the California-headquartered company's email.

What information did hackers access from Hot Topic shoppers?

Shoppers whose accounts were logged into by hackers during the breach may have had their name, email address, order history, phone number, month and day of their birth and mailing address accessed, Hot Topic said.
