On Friday, daily shopping deals website Catch of the Day, contacted its customers to advise of a data breach affecting customer accounts created before 7 May 2011.

In the email it confirms that customer names, delivery addresses, email addresses and encrypted (hashed) passwords were compromised, with some users’ credit card information also affected.

It has not provided any guidance in relation to the delay between the time of the breach and its notification of the incident, however its statement includes:

‘With technological advances it means there is an increasing risk that those hashed passwords may become compromised, which is why we are asking all those users with accounts created before 7 May 2011 to change their passwords.’

If you were registered with Catch of the Day before 7 May 2011, you should change your password immediately.

If you reuse any of these logon details elsewhere you should also change your passwords for those sites immediately.

If you had credit card information registered with Catch of the Day before 7 May 2011, you should monitor your bank accounts for any suspicious activity. You can also contact your bank to seek further advice.

Catch of the Day’s notification email states that it acted quickly at the time of the attack to shut it down, and that it notified the police, the Australian Privacy Commissioner, banks and credit card companies that took action which included cancelling some credit cards.

If you registered with Catch of the Day after 7 May 2011, the company advises that you should not be affected, however, you may consider changing your password as a matter of precaution and good practice.

The company also states that its other group sites were unaffected. These include Scoopon, Mumgo, Grocery Run, Eat Now and West Avenue.

Further press statements may be provided by Catch of the Day. You can monitor catchoftheday.com.au for more information.

Protecting your credit card

Every site you provide credit card information to will use different technology and expertise to manage the security of data they keep about you. While many take all the available precautions, others may not, and despite the best intentions, even well-known sites have been compromised. You should consider this risk whenever you provide credit card information to a site while signing up.

Some of the ways to minimise your risk include:

  • Using reputable third party payment services (such as PayPal). (Of course many of these have also been targeted by hackers in the past.)
  • Using a separate credit/debit card with limited funds in case it is compromised.
  • Minimising the number of places where your credit cards are registered online.
  • Removing your information from sites you no longer use. (Although sites may still retain your information.)
  • Reading the security information offered by websites when you sign up. Good websites will often promote their security technology and practices, particularly if you are providing credit card information.
  • You can also Google these companies to see if they have any previous security concerns.
