NEW YORK (AFP) - Giant US retailer Target said Friday that its recent data breach affected about 70 million customers, more than it initially estimated, and that the hacking incident had hit December sales.

Target, one of the biggest US retailers after Wal-Mart Stores, sharply lowered its fourth-quarter earnings outlook and said it was unable yet to estimate the costs related to the breach.

Target revealed on December 19 its payment card data had been breached, affecting about 40 million customers. The stolen data included credit and debit card data, customer names and PIN (personal identification data) numbers.

But in investigating the November 27-December 15 breach, Target said, it uncovered other types of information were also stolen. The information theft includes names, mailing addresses, phone numbers or email addresses for up to 70 million people, it said in a statement.
