JD Wetherspoon, one of the biggest pubcos in the UK, has suffered a huge data theft incident, with hackers making off with the details of over 600,000 customers, including the details of around 100 credit and debit cards.
The company revealed today that its old website, was hacked in June and an associated database, containing the details of 656,723 customers and an unknown number of employees, was stolen.
The customer details were, in the majority of cases, limited to names, phone numbers, dates of birth, and email addresses, but 100 of those affected had "extremely limited credit/debit card details ... accessed".
"Only the last four digits of the card numbers were obtained since the remaining digits were not stored in the database. Other information, such as the customer name and the expiry date was not compromised," the company said in a statement.
"As a result, these credit/debit card details cannot, on their own, be used for fraudulent purposes."
However, Simon Keates, a consultant in mobile security at Thales e-Security, said the theft of the other personal details "is of no less significant concern".
"In fact, theft of card details is relatively easy to 'deal with' - they can be blocked and replaced," he said. "It's the other - seemingly innocuous - information that can pose a bigger problem.
"Details such as you mother's maiden name, your date of birth, and where you live can be pieced together relatively easily by would-be criminals and used as bait for targeting phishing attacks and identity theft to access more sensitive this information."
Mark James of IT security firm ESET added: "John Hutson, the CEO of JD Wetherspoon, has stated that the breach affected the chain's 'old website', which has since been replaced in its entirety.
"There is a high possibility that little or poor security was involved in the original creation of the [old] site and that in itself led to the site being rewritten. If this was the case, it would be easy to gain access to that data and retrieve all the information and leave without anyone ever noticing."
James and several other security experts have also raised concerns over the fact it took six months for the company to become aware of the breach.
In a statement, the Information Commissioner's Office (ICO) told IT Pro: "We are aware of an incident at JD Wetherspoon and are making enquiries."
