Credit card security breached at hotel group

25 Jun 2003 has learned that the Marriott International hotel group is the merchant at the centre of the massive security breach which has lead to 3,000 Irish credit cards being reissued and an estimated 60,000 worldwide.

News of the incident began to emerge yesterday, although no merchant was named. It is believed that Irish financial institutions have been aware of it for the past week. AIB and Bank of Ireland have each already contacted approximately 1,000 customers in order to reissue cards which may have been compromised by the fraud. It is understood that Permanent TSB has contacted around 100 of its customers in connection to the incident.

Although it has only just come to light, it is understood that security had been compromised for approximately one year to eighteen months. It is believed that the security breach came to light once the affected cards began to be used to make purchases. has learned that the form of fraud involved was skimming, i.e. the illegal copying of a card’s data. This is one of the most common forms of credit card fraud and often takes place out of sight of the owner when the card has been handed over to pay for goods or services.

A spokesperson for Visa declined to comment on the incident, other than read a pre-prepared statement. Visa would not give a figure for the number of cards affected worldwide, although sources close to the banking industry give an estimated figure of 60,000 cards.
