It's just been disclosed that a hacker stole
sensitive data from computer systems used by TJX, parent company of
retailers TJ Maxx and Marshalls. HomeGoods, A.J. Wright, Winners and
HomeSense stores, all subsidies of TJX, may also be affected.
The hackers targeted systems which TJX uses to handle credit and debit
transactions for stores in the U.S. and Puerto Rico, but the company admits its
still investigating the full depth of the compromise.
TJX representatives said the security breach occurred sometime in May, but the
compromise continued until mid-December. The unauthorized intrusion was
initially detected by the company sometime in December but only publicly
revealed last week.
Visa USA is providing help to the banks of all affected customers. The
Bank of America and American Express are also watching accounts that may be
used for fraudulent transactions. TJX has established a helpline for all customers
who have questions or concerns about the incident: 866-484-6978 in the United States,
Canada and 0800-77-90-15 in
the United Kingdom and Ireland.
TJX has not disclosed how many customers were left vulnerable from the security
breach, though it states that transactions it knows are compromised occurred
between May and December 2006 and transactions in 2003.
TJX urges customers to check their bank transactions for irregular behavior.
