Your Value Your Change Short position was hit by an extensive theft of its customers' credit-card and debit-card data during the busy holiday-shopping season, a brazen breach of the major retailer's information security.
The company early Thursday said a data breach may have affected about 40 million credit card and debit card accounts between Nov. 27 and Dec. 15. Target said it alerted authorities and financial institutions immediately after it found out about the unauthorized access. It added that it is joining with a forensics firm to conduct an investigation into the incident.

"We take this matter very seriously and are working with law enforcement to bring those responsible to justice," said Target CEO Gregg Steinhafel in a statement.
The Wall Street Journal reported the breach Wednesday, citing people familiar with the matter.
The theft was national in scope and happened in stores, not online, and may have involved tampering with the machines customers use to swipe their cards when making purchases, people familiar with the matter said.
The data affected in the breach included customer names, credit or debit card numbers, expiration dates and CVV security codes, according to a notice posted for customers on the Target website.
Target officials were able to determine and resolve the unauthorized access on December 15, though it remains unclear who conducted the data breach and how.
"This was obviously a very sophisticated crime," said Molly Snyder, a Target spokeswoman.
The Secret Service is investigating the breach, a spokesman said, but wouldn't discuss details of the incident while the investigation is ongoing. Secret Service often investigates significant hacks of credit-card data, as part of its mission is to safeguard the country's financial infrastructure and payment systems.
The discount chain has 1,797 stores in the U.S. and another 124 in Canada.
The apparent breach occurred during the period when Americans kick off their holiday shopping and store traffic is around its highest of the year. Retailers try to lure shoppers to stores on Black Friday with "door buster" deals and overnight hours that often draw big crowds. The breach may have gone into the Monday after Thanksgiving, one of the people said.
The thieves gained access to data that is stored on the magnetic stripe on the back of the credit and debit cards, according to the people familiar with the breach. The stripe contains data that is valuable for making counterfeit cards, such as account numbers and expiration dates, but it wasn't immediately known which data was vulnerable.

Hackers typically aim to sell such information in bulk on the black market to people who use it to produce fake credit or debit cards. Crime rings can use the fake cards to buy gift cards from major retailers and convert them eventually into cash, according to investigators and former U.S. officials.
