MasterCard hack opens door for phishing attack

by Nikola Strahija on June 23rd, 2005 Fraudsters have been quick to launch phishing attacks in a bid to cash in on the publicity surrounding a security breach involving MasterCard International that may affect up to 40 million credit card holders.

The clumsy phishing attack, spotted by Secure Computing, is unlikely to fool many but illustrates how fraudsters are quick to adapt to current events in instigating security assaults.

MasterCard International is notifying member financial institutions of possible fraud risks following a security breach at CardSystems Solutions, a third party processor of payment card data. The breach of payment card data "potentially exposed more than 40 million cards of all brands to fraud", MasterCard warns.

Approximately 13.9 million of these are MasterCard-branded cards. CardSystems discovered a "potential security incident" on 22 May and notified the FBI about the problem the next day but the breach only became public on Friday (17 June) just a day before it was exploited in phishing attacks. These attacks made no specific reference to the security breach so it looks as if fraudsters used "one they'd prepared earlier".

Here is an example of phishing e-mail:
