T&T Supermarket, Canada’s largest Asian grocery store chain, has shut down its website after a cyberattack that may have exposed the personal information of 58,000 people.

The company says “unauthorized users” hacked into their website on June 6, 7, 11 and on June 14 to 17.

Customers placing online orders or applying for jobs may also have been tricked into downloading malware onto their computers.

T&T, which is owned by Loblaws, says affected customers could have had their user names, passwords, email addresses, cellphone numbers, street addresses as well as their names compromised.

But the company says it does not collect credit card information, driver’s licenses, birth dates or social insurance numbers through its website.

T&T said it temporarily suspended its website and has brought in security experts to conduct an investigation.

Meanwhile, the company will be contacting affected customers and is advising those who may have been exposed to change their passwords and run an antivirus on their computers.

T&T, which is based in Richmond, B.C., has three locations in Toronto — two in Scarborough and one in the Port Lands — as well as several locations in the GTA, including Vaughan, Markham, Richmond Hill and Mississauga.

Affected customers can contact T&T at pr@tntsupermarket.com or 1-855-296-2342.
