Some retailers launched online deals well in advance of Thanksgiving, Black Friday and Cyber Monday.
The daily deal provider says no consumer card data was accessed.
LivingSocial said today it had experienced a “cyber-attack” that exposed some customer data, but not customers’ payment card data nor financial information for merchants. The daily-deal provider asked customers to reset their LivingSocial passwords.
The attack “resulted in unauthorized access to some customer data from our servers. We are actively working with law enforcement to investigate this issue,” LivingSocial said in a message to consumers.
LivingSocial said that the attack affected data for some 50 million consumers. The information accessed included names, e-mail addresses and dates of birth. Further details from LivingSocial were not immediately available.
Earlier this year, LivingSocial raised $110 million that will increase reserves and fund strategic moves for the daily deal operator and Groupon Inc. competitor.
